Query Assistance
Mar 8, 2006
I am trying to pull some "notes" from a sql database.....the notes that
are put into the database come via the web and the user is entering it
for a certain task. they are stored in their own table and field and
get assigned and incremental ID #.
I want to be able to pull up the latest entry to the task, not all of
the notes just the latest one.. The entry does get a timestamp in the
field so I am thinking I might be able to look at that field
somehow.... Right now my query shows all notes / entries for the task.
I am an intermediate sql query guy so I hopefully expained enough to
get assistance.
Let me know if you need to know more.

I am trying to build a related article display. I have a SQLDataSource that I want to be able to select information (Category) from the table (Articles) based on a querystring (ID). SELECT [Category] FROM [Articles] WHERE ([ArticleID] = @ID) which for an example, lets say ID = 1, and it results as Category = Health.That is easy enough, but how would I then select all columns from the table WHERE Category = Result of first SELECT? SELECT * FROM [Articles] WHERE ([Category] = ??? Result of prior select) Can this be done in 1 select command, or would a store procedure need to be written? I am a little lost, sincr I am using a SQLDataSource, and it will be displayed with a Repeater. Thanks!

First off, here is my query:SELECT DeviationDist.DEVDN, DeviationDist.DEVDD, DEVDA, DEVCT, DEVST, DEVBG, DEVDV, DEVPS, DEVAT, DEVCN, DEVCF, DEVCP, DEVCEFROM DeviationDistINNER JOIN DeviationContact ON DeviationContact.DEVDN = DeviationDist.DEVDNWHERE DeviationDist.DEVDN = '200270'ORDER BY Deviationdist.DEVDN DESCI'm joining the deviationcontact table to the deviation dist table by DEVDN. This query works fine except when the DeviationContact table doesnt contain any records for the DEVDN that the DeviationDist table does contain. In my app, Deviationdist will always have an record for each DEVDN, but DeviationContact may not. I would like to still get the results back for what records exist in the DeviationDist table, even if DeviationContact has no associated records, but still show them if it does...

Hi,
I have a need to renumber or resequence the line numbers for each unique claim number. For background, one claim number many contain many line numbers. For each claim number, I need the sequence number to begin at 1 and then increment, until a new claim number is reached, at which point the sequence number goes back to 1. Here's an example of what I want the results to look like:
ClaimNumber LineNumber SequenceNumber
abc123 1 1
abc123 2 2
abc123 3 3
def321 5 1
def321 6 2
ghi456 2 1
jkl789 3 1
jkl789 4 2
So...
SELECT ClaimNumber, LineNumber, <Some Logic> AS SequenceNumber FROM MyTable
Is there any way to do this?
Thanks,
Dennis

I realize this query is inherently incorrect, but my issue is mainly syntax. The line, "WHEN a.order_id <> b.order_id THEN" is wrong. I want to ensure that a.order_id is not in the settlement table. So I was thinking something along the lines of "WHEN a.order_id not in (select order_id from settlement)" which I know will cause a slower response time, but I'm willing to deal with it. In any case, that syntax doesn't appear to work.
sum(
CASE
WHEN a.ready_to_pay_flag = 'Y' and a.deduction_type = 'E' and (
CASE
WHEN a.order_id <> b.order_id THEN
a.transaction_date
ELSE
b.delivery_date
END) used_date datediff(d,used_date, ".$cutOffDate.") < 30) THEN
a.amount
END) earn_amount_rtp_curr,
Any help here would be hotness!
Thanks!

I am trying to get a running total. I need the query to reset the running total for each year/id. Below is the sample query. Any help would be greatly appreciated.
Code:
CREATE TABLE #valueset (k1 int, date datetime, groupByThis nvarchar(50), c1 int)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13024, '09/14/2007', '2007', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '09/15/2006', '2006', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '10/13/2006', '2006', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '09/14/2007', '2007', 2)
SELECT v.k1, v.date, v.groupByThis, v.c1, RunningTotal=SUM(a.c1)
FROM ( SELECT k1, date, groupByThis, c1, RANK() OVER (PARTITION BY k1 ORDER BY groupbythis, date) as Rank
FROM #valueset ) v
CROSS JOIN
( SELECT k1, date, groupByThis, c1, RANK() OVER (PARTITION BY k1 ORDER BY groupbythis, date) as Rank
FROM #valueset ) a
WHERE a.Rank <= v.Rank
AND a.groupByThis = v.groupByThis
GROUP BY v.k1, v.date, v.groupByThis, v.c1
ORDER BY v.groupByThis, v.date
Drop Table #valueset
Expected Results:
k1 date groupbythis c1 RunningTotal
13025 2006-09-15 00:00:00.000 2006 1 1
13025 2006-10-13 00:00:00.000 2006 1 2
13024 2007-09-14 00:00:00.000 2007 1 1
13025 2007-09-14 00:00:00.000 2007 2 2
13025 2007-11-09 00:00:00.000 2007 1 3
I am almost there - any help would be great. I need to reset the running total after every "groupbythis" for every "k1"
Thanks.

I am relatively new to the use of coplex queries. Here is a task that I am trying to accomplish.
Source table.
Address
ID
Workstation
Test-a
1
WS1
Test-b
2
WS1
Test-a
5
WS2
Test-d
3
WS2
Test-b
7
WS2
I am trying to write a query that will display this result into Excel.
Address
Duplicate
WS1
WS2
Test-a
Yes
1
5
Test-b
Yes
2
7
Test-d
No
Basically I am trying to identify if there is a duplicate address, if so mark it as such in the duplicate column and then placing the ID into a column under the Workstation.
I only want to see the duplicated address once (Distinct?) but mark that it is indeed a duplicate and mark the ID's that it has under the workstations.
Any ideas? I have created a query that does pull the data in the first example that is doing a DTS export to excel. However I need to format this to show the second example.
I appreciate any help I can get on this.

Hello,
I have two tables, USER and ROTATION. What I would like to display is the Maximum Start_Date and Maximum End_Date from the ROTATION Table along with the First_Name and Last_Name that is associated with that max entry.
When I just create a select statement that asks for the max value of the Start_Date and End_Date, I get the value I see. However when I try to add the First_Name and Last_Name to the mix, I get the Max Start and End Date Values of all the people in the User Table. I only want one result returned. I'm probably missing something very simple here. Any assistance would be appreciated.
The SQL code I am currently using:
Code SnippetSELECT [USER].FIRST_NAME, [USER].LAST_NAME, MAX(ROTATION.ONCALL_START_DATE) AS Expr1, MAX(ROTATION.ONCALL_END_DATE) AS Expr2
FROM ([USER] INNER JOIN
ROTATION ON [USER].USER_ID = ROTATION.USER_ID)
GROUP BY [USER].FIRST_NAME, [USER].LAST_NAME
Example of my desired result:
First_Name Last_Name OnCall_Start_Date OnCall_End_Date
John Doe 8/10/08 8/17/08
John Doe should be the only result returned because he would have the highest OnCall_Start and OnCall_End in the ROTATION Table.

I am new to SQL and aftering reading my SQL For Dummies book, I still am unsure how to accomplish this task.
The table I need to query contains resident census information. There are multiple rows for each resident. I need to determine if the resident is still active, so I only need to read the last row for each resident to make this determination.
What method can I use to read only the last row for the resident. Here is what I tried previously, but it returns multiple rows for each resident.
select a.firm_id_code as FacAddOnNum,
f.shortname as FacName,
left(a.resident_code,6) as ResidentCode,
(r.res_first_name + ' ' + r.res_last_name) as ResidentName,
a.LastDate,
a.cens_trans_type
from (select firm_id_code,
resident_code,
max(dt_cens_trans) as LastDate,
cens_trans_type
from arrescensus
where firm_id_code = @FacId
group by firm_id_code, resident_code, dt_cens_trans, cens_trans_type) as a
join corp_info.dbo.facilityinfo as f on (a.firm_id_code = f.addonnum)
join arresidents as r on ((r.firm_id_code = a.firm_id_code) and (r.resident_code = a.resident_code))
Any help with this is greatly appreciated!

I've got a website with dynamic content, each page (subject) got an ID. On every page there can be a number of links. These are either links to internal other pages on that website or external links.
For the internal links the only thing I need is the ID and Title of that page. Those can be found in the Tbl_subjects. As for external links I need ID, Title and URL which can be found in the Tbl_ext_links.
I've got a table named Tbl_linkboxes with:
- a Subject ID which means that this link belongs on this subject page.
- Link ID which is either an ID from Tbl_subjects or Tbl_ext_links
- External a boolean column to indicate if the Link ID refers to the Subject table or the External links table
There's basically 2 questions:
1) How to make this work? I've got a query below as feeble attempt
2) Should I really really really consider to use 2 columns for IDs and removing the External boolean. And simply setting one of those fields in the columns to >0 while the other is 0.
Okay, here's my attempt
PHP Code:
SELECT s.Sub_id, s.Link_id
(l.external IS FALSE, (SELECT Title FROM Tbl_subjects), (SELECT Title,URL FROM Tbl_ext_links)
FROM Tbl_subjects s
WHERE s.Sub_id = <some id>
Not sure if I should work with IIF here to make it work or something else. I'm almost tempted to kick the boolean column overboard and introduce a JOINT on both columns then, one for external link ids and other for internal page ids.
Amazing how long one can stare at a query and not being able to get it right

I'm attempting to write and update query. So far I have written the following:
update vwDISTCITY_TAXCODE
set tax_code='04'
where DIST_CITY='04'AND year_id=2007 AND frozen_id=0 AND p_id=93549 AND total_taxes=isnull
The last part of the query "total_taxes=isnull" is where the problem lies. Essentially I want to say if all of the other things are true and there is a null value in the total_taxes column, then I I want to set the tax_code to '04'. However how would I phrase the last part correctly?
Thanks!

Good Day;I would appreciate assistance developing a query that I haven't beenable to develop without using a second table. I wish to count thenumber of records that are still open on the first of each month.Each record has an open date and a close date or the close date isnull i.e., the record is not yet closed. I've previously beaten thisby building a table, simply a list of the dates for the first of eachmonth for the next ten years or so, and then selecting values basedupon a date selected from that table. However I'd be happier if Icould do it without the second table. I'd be prepared to accept theMin(Date) for each month as being the first of the month.I've included some DDL statements to build and populate the table ifthat helps. Since the selection is rather small and all the opendates are very close together I think the result will be simply adecreasing count from the month the first record is opened till today.A pseudo code select statement might look likeSelect Min(DateOpened) As DateOfInterest, Count(*) as [Qty Still Open]FROM DetailTWhere DateReceived > DateOfInterest or DateReceived is Null andDateOpened < DateOfInterestGroup by Min(DateOpened)Order by Min(DateOpened)I hope I've explained it sufficiently well.CREATE TABLE [dbo].[DetailT] ([Autonum] [int] IDENTITY (1, 1) NOT NULL ,[QDNumber] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[DateOpened] [smalldatetime] NOT NULL ,[DateReceived] [smalldatetime] NULL ,)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C15788', '06/04/2005 9:35', 07/04/2005)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B16091', '06/04/2005 9:36', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B15001', '06/04/2005 9:51', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('M18696', '06/04/2005 9:56', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C14969', '06/04/2005 10:05', '10/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('O10091', '06/04/2005 10:08', '12/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('D01197', '06/04/2005 10:13')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('H15001', '06/04/2005 10:15', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('J15090', '06/04/2005 10:24', '08/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('J01202', '06/04/2005 10:31')Insert into DetailT (QDNumber, DateOpened)VALUES('G01193', '06/04/2005 10:32')Insert into DetailT (QDNumber, DateOpened)VALUES('K01164', '06/04/2005 10:35')Insert into DetailT (QDNumber, DateOpened)VALUES('K01162', '06/04/2005 10:48')Insert into DetailT (QDNumber, DateOpened)VALUES('F01124', '06/04/2005 10:59')Insert into DetailT (QDNumber, DateOpened)VALUES('H01147', '06/04/2005 11:01')Insert into DetailT (QDNumber, DateOpened)VALUES('S15068', '06/04/2005 11:10')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('E12322', '06/04/2005 11:32', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('A12205', '06/04/2005 11:37', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('D12259', '06/04/2005 11:40', '07/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('C03394', '06/04/2005 11:51')If you made it this far thank you for your patience.

I am trying to generate some datasets with some queries...With a given series information, it should return PART_NOs that has STD= 1 and a unique price at that particular 'START', and keeping the'TYPE' in consideration...DB examples below:Main DBIDPART_NOSERIESSTD1A-1A12A-2A13A-3A14D-1D15D-2D0Price DBIDPART_IDTYPESTARTPRICE501X100050511X1000040521Y100060531Y1000050542X100050552X1000040562Y100060572Y1000050582X100090etc.main.ID and Price.PART_ID are paired together.So in an example case, lets say I am querying for SERIES A, with TYPEX. A table should be outputted something likePART_NOA-1100050A-11000040A-3100090Note how it skipped printing A2 because the price is the same as A1.I'm really looking for the SQL code here... I can't get it to filter ondistinct price.SELECT MAIN.PART_NO, PRICING.START, PRICING.PRICEFROM MAIN, PRICINGWHERE (MAIN.SERIES LIKE 'A')AND (MAIN.STD = '1')AND (PRICING.PRICE != '')AND (PRICING.TYPE = 'X')AND (MAIN.ID = PRICING.PART_ID)I've been trying to use GROUP BY and HAVING to get what I need but itdoesn't seem to fit the bill. I guess I'm not terribly clear on how Ican use the SQL DISTINCT command...? If I try and use it in my WHEREstatement it gives me syntax errors, from what I understand you canonly have distinct in the select statement? I'm not sure how tointegrate that into the query to suit my needs.Thanks for any help.

I have a query that gets three columns of data. PRODUCT_ID, SMALL_TEXT_VALUE, AND LARGE_TEXT_VALUE. I'd like to know if there is a way that I can alter my query below so that whenever SMALL_TEXT_VALUE is Null, it uses the value thats in the LARGE_TEXT_VALUE column. Whenever the small is null, the data I need is in the large column. My Query: Select EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID, EXTENDED_ATTRIBUTE_VALUES.SMALL_TEXT_VALUE, EXTENDED_ATTRIBUTE_VALUES.LARGE_TEXT_VALUEFrom EXTENDED_ATTRIBUTE_VALUES, EXTENDED_ATTRIBUTESWhere EXTENDED_ATTRIBUTE_VALUES.Ext_Att_ID = EXTENDED_ATTRIBUTES.Ext_Att_IDORDER BY Product_ID DESC

I got some help on here before with building my query. I thought this was working fine but it turns out when there are multiple records for a column type, it only grabs the first one. I need to get all records. Is there an alternative to MAX? I needed to structure it like this because I needed to return each row as a column and this was the way suggessted before.
My query:SELECT TOP (100) PERCENT PRODUCT_NUMBER, PRODUCT_NAME,
MAX(CASE WHEN ColumnName = 'Federal Specification Number' THEN TheValue ELSE NULL END) AS [Federal Specification Number]FROM (SELECT dbo.PRODUCT_FEATURE_VALUES.PRODUCT_ID AS ProductID, dbo.SHARED_FEATURE_VALUES.FEATURE_TEXT_VALUE AS TheValue,
dbo.SHARED_FEATURE_TYPES.FEATURE_TYPE AS ColumnName, dbo.PRODUCTS.PRODUCT_NUMBER, dbo.PRODUCTS.PRODUCT_NAME
FROM dbo.PRODUCT_FEATURE_VALUES INNER JOINdbo.SHARED_FEATURE_TYPES ON
dbo.PRODUCT_FEATURE_VALUES.FEATURE_TYPE_ID = dbo.SHARED_FEATURE_TYPES.FEATURE_TYPE_ID INNER JOINdbo.SHARED_FEATURE_VALUES ON
dbo.PRODUCT_FEATURE_VALUES.FEATURE_VALUE_ID = dbo.SHARED_FEATURE_VALUES.FEATURE_VALUE_ID INNER JOINdbo.PRODUCTS ON dbo.PRODUCT_FEATURE_VALUES.PRODUCT_ID = dbo.PRODUCTS.PRODUCT_ID
UNIONSELECT dbo.EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID AS ProductID, ISNULL(dbo.EXTENDED_ATTRIBUTE_VALUES.SMALL_TEXT_VALUE,
dbo.EXTENDED_ATTRIBUTE_VALUES.LARGE_TEXT_VALUE) AS TheValue, dbo.EXTENDED_ATTRIBUTES.COLUMN_NAME AS ColumnName, PRODUCTS_1.PRODUCT_NUMBER, PRODUCTS_1.PRODUCT_NAME
FROM dbo.EXTENDED_ATTRIBUTE_VALUES INNER JOINdbo.EXTENDED_ATTRIBUTES ON
dbo.EXTENDED_ATTRIBUTE_VALUES.EXT_ATT_ID = dbo.EXTENDED_ATTRIBUTES.EXT_ATT_ID INNER JOIN
dbo.PRODUCTS AS PRODUCTS_1 ON dbo.EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID = PRODUCTS_1.PRODUCT_ID) AS t1
WHERE PRODUCT_NUMBER = '02083'
GROUP BY PRODUCT_NUMBER, PRODUCT_NAME
ORDER BY PRODUCT_NUMBER
This returns:
Product_Number Product_Name Federal Specification Number
02083 Di-Electric Grease, 10.5 Wt Oz FDZ-CFR-21-178.3570
There is another record for Federal Specification Number I need to return as well. If I change to MIN, it gets the other record. Anyway I can get both?

I have two tables that are pretty standard I think. Table a has product descriptions and one of those fields is a price. I have a second table that contains fees based on the price. so table B looks like this.
min max fee
0 19.99 2.50
20.00 49.99 3.50
50.00 1000.00 5.50
the max ends up around a million just to be sure we cover all prices. my problem is this I need a very efficient query to
poll all the values from A and the correct value from B. All the attempts I have made are not working. I also have to make sure this query is extremely efficient as it is executed several times a minute. If there is a better way in general to structure this I am all ears. I wanted to avoid placing the fees in the product table as the fees are updated often, but if its the only way to get this to work, then that is where I will go.
Thanks everyone

The View SQL below takes 1:50 minutes to execute. I am looking for a way to improve processing time and keep the view select statements as simple as possible.
One part of the view that could be restructured is the lookup for the current term (TERM_TBL - bolded). When I hard code the current term my execution time drops to about 13 seconds
There are three possible values for the current term; one for each of our three acedemic careers (UGRD, CONT, & EXED). Could this information be looked up once and then each enrollment selected based upon the appropriate academic career current term value? If so, how would it be restructured? Currently, the lookup is done for every enrollment record.
There are no common fields between the NAMES table and the TERMS_TBL.
Code Snippet
SELECT A.EMPLID, A.LAST_NAME_SRCH, A.FIRST_NAME, A.MIDDLE_NAME, A.LAST_NAME
FROM NAMES A
WHERE A.EMPLID IN (
SELECT DISTINCT B.EMPLID
FROM STDNT_ENRL B
WHERE B.INSTITUTION = 'AAAAA'
AND B.STRM >= (
SELECT DISTINCT T.STRM
FROM TERM_TBL T
WHERE T.INSTITUTION = B.INSTITUTION
AND T.ACAD_CAREER = B.ACAD_CAREER
AND T.TERM_BEGIN_DT <= GETDATE()
AND T.TERM_END_DT >= GETDATE())
AND A.EMPLID NOT IN (
SELECT DISTINCT C.EMPLID
FROM SRVC_IND_DATA C
WHERE C.INSTITUTION = 'AAAAA'
AND C.SRVC_IND_CD = 'DPL' )
AND A.NAME_TYPE = 'PRI'
AND A.EFFDT = (
SELECT MAX(D.EFFDT)
FROM NAMES D
WHERE D.EMPLID = A.EMPLID
AND D.NAME_TYPE = 'PRI'
AND D.EFFDT <= GETDATE() )
Any suggestions will be gladly accepted. Keep in mind that the new and much improved must be legal within the context of a view select statement.
Thanks,
Steve

Hiya,
This is a fairly detailed problem, so this will be a long post... I do appologize. I have been agonizing over this now for over a week and cannot find a viable solution. Hopefully one of you can help.
First off, I work for a realestate company, and this query will display a list of properties based on a number of different criteria and criteria types. There are multiple tables involved:
dbo.Prop:
Property Database. Holds basic info about each property
dbo.Prop_Features:
holds all the features (such as Pool, Carpet, Drapes etc) for each property. The only information stored in this table are PropID and FeatureID (PropID being the Identity of the Prop table, FeatureID being the Identity of the Features Table)
dbo.Features
Holds information on each possable "feature" in the system.
dbo.Members
Holds basic information and criteria for each of our members.
dbo.Members_Features
This table holds the MemberID and FeatureID where members have chosen one ore more features to be used for criteria when searching for a property.
Ok, now... That said, here is my problem. The query I had written (by a professional hired thru Robert Half Technologies) takes over 30 seconds to execute. I will post a copy of that SP below. This is unacceptable. We have to process thousands of these per hour, and a 30 second process time is very bad. Can any of you give me a idea of how to better approach this problem?
In the code below, you will notice there are other tables I did not mention - they are not important. The Speed problem is surrounding a single function, which I will mention below.
CREATE PROCEDURE dbo.Member_Get_List

Okey, now. Please notice this part of that code:
dbo.Prop_Get_Feature_List_Fun(P.PropID) + CASE Len(P.CustomFeatures)

ELSE ', ' + P.CustomFeatures
End
+ CASE Len(P.Comments)
WHEN 0 THEN ''
ELSE ', ' + P.Comments
End
AS 'Features',
This function is the cause of the speed problem, methinks. When run alone, it takes 29 seconds to process with the same MemberID that takes about 33 seconds to process completely (the whole Proc). This function simply returns a list of comma delimited features for each property, for displaying on a customer list. Here is that function:
CREATE Function dbo.Prop_Get_Feature_List_Fun (@PropID int)
RETURNS Varchar(3500)
AS
BEGIN
Declare @FeatureList Varchar(3500)
select @FeatureList = Coalesce(@FeatureList + ', ', '' ) + F.FeatureName
FROM
Prop P
INNER JOIN
Prop_Features PF
ON
P.PropID = PF.PropID
INNER JOIN
Features F
ON
PF.FeatureID = F.FeatureID
WHERE
P.PropID = @PropID
ORDER BY
F.FeatureName
Set @FeatureList = isnull(@FeatureList,'Please call for features.')
RETURN @FeatureList
END
Now, I know I probably gave lots more information then needed to solve this issue - but its better to have too much then not enough.
Any help at all in speeding up this function or describing another way to do this would be most appreciative.

I have a table that was created as follows
create table call_summary (
row_date smalldatetime,
[700] int,
[730] int,
[800] int,
[900] int)
I have a query that returns the following
date interval (int) calls (int)
2008-01-07 00:00:00 700 0
2008-01-07 00:00:00 730 0
2008-01-07 00:00:00 800 0
2008-01-07 00:00:00 830 9
2008-01-07 00:00:00 900 8
I am looking for a way to get my table mentioned above to look like this
row_date [700] [730] [800] [830] [900]
2008-1-7 0 0 0 9 8
does anyone have any slick ideas on how I can accomplish this task?

Hi Folks,
I have a slight problem designing two drop down lists accessing my database as some clients are listed twice because they are located in multiple citys
I have one table called Clients with the following columns
Client
City
F_name
L_name
ID
I am using SELECT DISTINCT Client FROM Clients for my first Dropdownlist with a postback etc.
e.g.
Brown
Black
The Second Dropdownlist must select the different Distinct City Values where they are located on selecting Dropdownlist one
e.g.
Brown > London, New York
or
Black > Singapore and Boston
What SQL Code can i place so the second dropdownlist will select the correct values on selecting the first Dropdownlist.
Thanks,
Sully

I need some explanantion on the following query that I'm trying to run:
if exists (select * from sysobjects
where id = object_id ('slice_trace')
and sysstat & 0xf = 3)
delete from slice_trace
where control_seq_number = 130
and claim_number = 7912450
When I run this query within a database where the slice_trace table does NOT exist, it still seems to execute the delete statement and hence fails because the object is not there.
Essesntially I need this statement to execute only in databases where the table exists.

I new it was a mistake changing from mysql to mssql! I'm having difficulty with the following and would really appreciate any help you could offer.
I have two tables.
The first [users] has personal details:
[id]
[business_name]
[title]
[surname]
[firstname]
The second [orders] has their orders:
[order_id]
[user_id]
[order_date]
[order_price]
I need a query that returns the latest record from [orders] for each member, with member details, but only where the latest order was within (now)-425.
Many thanks.

Dear friends!
I'd like to ask your assistance in writing some T-SQL.
I have a table
MYTABLE (THEDATE datetime, TEMPERATURE numeric(4))
3.02 15
4.02 16
5.02 16
8.02 13
10.02 15
11.02 15
12.02 19
I need a T-SQL without using analitic(range) functions like RANK or DENSE-RANK to provide the following output:
3.02 15
4.02 16
8.02 13
10.02 15
12.02 19
In other words I need to obtain only first occurance of the "neibough" adjacent rows where the temperature is equal.
Please advice.
Thanks in advance.

I have received a table of data that has a field containing dateinformation. Unfortunately it was derived from a MainFrame dump andoriginated as a txt file and was then ported into an Access MDB filebefore it became an SQL table. The date format is vchar(50) andactually is comprised of 6 charecters ie: 010104 for Jan 1 2004. Ineed to run a select statement for a range of dates such as 010104thru 030104. Unfortunately being a charecter field this returnsincorrect results under a majority of cases. Back in my dBase daysthere was a VAL() that could be used in this case but I have beenunable to find anything comperable in SQL. Can anyone help me please?Thanks in advanceSteve

Error: "A connection was successfully established with the server, but an error occurred during the pre-login handshake. (provider: SSL Provider, error:0 - The certificate chain was issues by an authority that is not trusted.) (Microsoft SQL Server)

I can terminal sevice in to the box and confirm my credentials work

The Certificate tab is clear under "Protocols for MSSQLServer", but the server does have certs I can see them in the "Certificate" dropdown.
Any help would be great.

Hey all,
I have been working for some time on this T-SQL statement and getting it to work the way I would like it to work. I have been reading through books and everything, but am still having trouble. I am pretty new to T-SQL so I am probably making some beginners mistakes.
Basically I am working on a SQL 2005 server and I have a single database with two tables. Below are the tables and the fields that I am using from each. The table name is in bold and the fields are plain.
Users
username (PK, varchar(7), not null)
full_name (varchar(50), not null)
call_history
queue (varchar(6), not null)
update_date (datetime, null)
status (char(1), not null)
Ok, now that you have the gist of the tables and fields. What I am trying to do is the impossible I think. Basically I work in a call center that supports software. The queue field is the identifier of what specialist is handling any call within the table. It can be linked to the "username" on the Users table. One thing I just noticed is that the varchar has a difference. Will that affect my below select statement?
SELECT u.full_name AS 'Specialist Name', COUNT (*)
FROM dbo.call_history c
LEFT OUTER JOIN dbo.users u ON c.queue = u.username
WHERE (c.status = 'P') AND (DATEDIFF(dayofyear, update_date, getdate()) >= 6) AND (DATEDIFF(dayofyear, update_date, getdate()) <= 9)
AND queue IN('alatif', 'AWILLI', 'AYOUNG', 'BPRING', 'CSKINN', 'DALDEN', 'DBACCH', 'DGIZZI', 'DKUSSA', 'DMCCUE',
'EKEPFE', 'GBACKH', 'GJONES', 'HESTAL', 'JBANKS', 'JCRICH', 'JDELGA', 'JFOLCH', 'JGRAVE', 'JHARRI',
'JLI', 'JMYERS', 'JPOPPE', 'JRICHA', 'JRIMME', 'JTHOMP', 'JWELLS', 'KDUKHI', 'KSTANL', 'LCHAMP', 'LGABOR',
'LHARVE', 'LMONTG', 'LSHORT', 'LTOM', 'MBECK', 'MJONES', 'MVANDE', 'NBROWN','NTOMPK', 'PELLIS',
'RATTAR', 'RDODGE', 'TANDRO', 'TBROWN', 'TDAVIS', 'TNDREX', 'TNORRI', 'YSOSA', 'YWILLI')
GROUP BY full_name
ORDER BY full_name
So here is my dilemma:
I am trying to emulate a spreadsheet that was given to me by my boss. This is pretty much going to determine whether or not I can get a job as the Web Developer. So the spread sheet displays the number of calls that have not been updated in X amount of days for all of our reps. I have been trying so many different varieties from nested SELECT statements now to joins. To put it simply enough, do I need to do a query that populates column by column?
Here is what it should look like:
http://i135.photobucket.com/albums/q129/tico1177/CropperCapture1.jpg
As you can see, I have to include everyone even if they have zero. That is where the problem comes in. When I use the above statement, the list shows up but takes away people from the list instead of keeping them and placing a null for the count. I have tried placing a HAVING statement at the bottom of the query to compensate for COUNT(*) = 0, but I get an error. I think because I have a WHERE statement.
I am trying to see if this whole thing can be done with a SQL statement to avoid having loop though in code. I basically want to populate a datagridview with the information that I gather.
Is this possible?
All help is greatly appreciated!

I know I need to go to Management, SQL Server Agent, Jobs, New Job. Do I put the stored procedure in the descriptions part? After that I'm lost what do I do.
