Conditional Where If Results
Nov 6, 2007
This is my query:
SELECT Class.ClassID, Class.Comments, Class.Address1, City.City, Class.State, Instructor.FirstName, Instructor.LastName, ClassInstructor.IsPrimary
FROM Class
LEFT OUTER JOIN City ON City.CityID = Class.CityID
LEFT OUTER JOIN ClassInstructor ON ClassInstructor.ClassID = Class.ClassID
LEFT OUTER JOIN Instructor ON Instructor.InstructorID = ClassInstructor.InstructorID
WHERE Class.ClassID = @ClassID
AND ClassInstructor.IsPrimary=1
The problem is that if the class doesn't have an instructor yet, the query doesn't return results because even though I am using a LEFT JOIN on the class table, the "ClassInstructor.IsPrimary=1" statement will cause no results. I want results from the other class fields even if the class doesn't have an instructor.
I tried this and it works but seems kinda inefficient:
SELECT @cnt=COUNT(*)FROM ClassInstructor
WHERE ClassID = @ClassID
AND ClassInstructor.IsPrimary=1
IF @cnt>0
BEGIN
SELECT Class.ClassID, Class.Comments, Class.Address1, City.City, Class.State, Instructor.FirstName, Instructor.LastName, ClassInstructor.IsPrimary
FROM Class
LEFT OUTER JOIN City ON City.CityID = Class.CityID
LEFT OUTER JOIN ClassInstructor ON ClassInstructor.ClassID = Class.ClassID
LEFT OUTER JOIN Instructor ON Instructor.InstructorID = ClassInstructor.InstructorID
WHERE Class.ClassID = @ClassID
AND ClassInstructor.IsPrimary=1
END
Is there a better way to do this?

Hello everybody,After several attempts of writing the query, I had to post myrequirement in the forum.Here is what I have, what I need and what I did.Table ACol1 Col21 Nm12 Nm23 Nm3Table BCol1 Col210 10020 200Table CCol1 (A.Col1) Col2 (B.Col1)1 102 10Table DCol1 (A.Col1) Col21 Value12 Value2I need results based on below criteria,1.Criteria - B.Col2 = 100ResultsetA.Col1 D.Col11 Value12 Value22.Criteria - B.Col2 =""A.Col1 D.Col11 Value12 Value23 NULL3.Criteria - B.Col2 =200Empty resultsetHere is the query I tried, but looks its not working. Probably there isa better way to do this.DDL and DML statements:create table #tab1 (a1 int, a2 nvarchar(20))create table #tab2 (b1 int, b2 int)create table #tab3 (c1 int, c2 int)create table #tab4 (d1 int, d2 nvarchar(20))insert into #tab1 values (1, 'nm1')insert into #tab1 values (2, 'nm2')insert into #tab1 values (3, 'nm3')insert into #tab2 values (10, 100)insert into #tab2 values (20, 200)insert into #tab3 values (1, 10)insert into #tab3 values (2, 10)insert into #tab4 values (1, 'value1')insert into #tab4 values (2, 'value2')selecta.a1, d.d2from #tab1 aleft join #tab3 bon a.a1 = b.c1left join #tab2 con b.c2 = c.b1left join #tab4 don a.a1 = d.d1wherec.b2 = [100 or 200 or ''] or exists (select 1 from #tab4 dwhere a.a1 = d.d1and c.b2 = [100 or 200 or ''] )The above query works well to give results for Criteria 1 and Criteria3, but doesn't return for '' (criteria 2). I couldn't manage crackingthe solution. I shall try once again, but meanwhile if anyone couldhelp me in this, that would be great.Thanks.

My source table has two columns... Policynum and PolicyStartdate and data looks like..
.
Policynum PolicyStartdate
123G 01/01/2012
456D 02/16/2012
789A 01/21/2012
163J 05/25/2012
Now my output should return based on 3 parameters..
First two parameters are date range... let say @fromdt and @todt
Third parameter is @policynum
Scenario-1: Enter dates in date range param and leave policynum param blank
Ex: policystartdate between '01/01/2012 and '01/31/2012'.... It returns 1st and 3rd rows from above in the output
Scenario-2: enter policy num in policynum param and don't select any dates
Ex: policynum ='456D' It returns 2nd row in the output
Scenario-3: Select dates in date range param and enter policynum in param
Ex: policystartdate between '01/01/2012 and '01/31/2012' and policynum
='163J'. it should return only 4th row even though dates were selected(Override date range when policynum is entered in param and just return specified policynum row in the output)
I need t-sql code to get above results.

Hello everyone,
Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query
executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.
Any help or suggestions will be much appreciated.
Thanks,
Larry

I have the following code in the color property of a textbox. However, when I run my report all of the values in this column display in green regardless of their value.
=SWITCH(Fields!Wrap.Value >= 3, "Red", Fields!Wrap.Value < 3, "Green")
I already tried =iif(Fields!Wrap.Value >= 3 , "Red", "Green") and got the same results.
Is it because this is a matrix report? What am I doing wrong?
Thanks in advance . . .

I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100
SELECT * FROM Customer WHERE
CountyId IN
(
SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId)
THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?

Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist.
My current SQL statement is as follows.
SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))"
So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated.
Thanks,
James.

Hi,
I have a web form that lets users search for people in my database they wish to contact. The database returns a paged set of results using a CTE, Top X, and Row_number().
I would like to give my users to option of removing individual people from this list but cannot find a way to do this.
I have tried creating a session variable with a comma delimited list of ID's that I pass to my sproc and use in a NOT IN() statement. But I keep getting a "Input string was not in a correct format." Error Message.
Is there any way to do this? I am still new to stored procedures so any advice would be helpful.
Thanks

Hi, when I copy and paste results from query analyzer into Excel it appears that values with zeroes at the end loose the zeroes. Example, if I copy and paste V128.0 into an Excel cell it comes out as V128 or if I copy 178.70 it displays as 178.7 - any ideas? I'm using SQL Enterprise Manager for 2000.

Im faced with the following design issue..
on my site there are different profiles: a city profile, a restaurant profile and a user profile.
in my DB:City profiles are stored in tbCities cityID int PK shortname nvarchar(50) forumID int FK (...)
Restaurant profiles are stored in tbRests restID int PK shortname nvarchar(50) forumID int FK (...)
User profiles are stored in tbUsers userID int PK shortname nvarchar(50) forumID int FK (...)
as you can see a single ID value (for CityID,restID or userid) might occur in multiple tables (e.g. ID 12 may exist in tbRests and in tbUsers)Each of these profile owners can start a forum on their profile.
forumID in each of the above tables is a FK to the PK in tbForums:forumID intforumname nvarchar(50) (...)
Now imagine the following:
a site visitor searches ALL forums...say he finds the following forums:ForumID Forumname1 you opinion on politics2 is there life in space?3 who should be the next president of the USA?
a user may want to click on the forum name to go to the profile the forum belongs to.And then there's a problem, because I dont know in which table I should look for the forum ID...OR I would have to scan all tables (tbCities,tbRests and tbUsers) for that specific forumid,which is time-consuming and I dont want that!
so if a user would click on forumID 2 (is there life in space?)
I want to do a conditional inner join for the tablecontainingforumID (which may be tbCities,tbRests or tbUsers)
select tablecontainingforumID.shortname FROM tablecontainingforumID tINNER JOIN tbForums f ON t.ForumID=f.ForumIDwhere f.ForumID=2
I hope my problem is clear..any suggestions are welcome (im even willing to change my DB design if that would increase effectivity)

Hi, is it possible to do a conditional WHERE in T-SQL? I have a table with a column that consists of a reference that starts with either a single alpha character or two alpha characters followed by four numeric digits (the numeric portion is always unique but the alpha isn’t). E.g. A1234, AB1235, AB1236, C1237, HT1238. What I want to do is select a range of rows based on the numeric portion of this reference column. In other words I want to select say 50 rows starting from row 1000 (rows 1000 to 1050) regardless of whether there is one or two alpha characters preceding the numerics.The Stored procedure I have so far works (using COUNT for testing) for selecting a range of rows that has two alpha's at the start. However, if I simply add an OR to the WHERE to select rows where there is a single alpha in the reference column, when a single alpha reference is found it will fail the first logical check for two alpha's giving an error condition. Therefore, how can I incorporate a conditional WHERE using IF or some alternative method, so that it will also give me all the rows in the number sequence that start with either single or double alpha's within the same SELECT / WHERE statement?
Thanks for any help.ALTER PROCEDURE [dbo].[sp_Test]
(
@startRef int,
@endRef int
)
AS
BEGIN
SELECT Count(*) FROM myTable
WHERE ((SUBSTRING(Ref,3,LEN(Ref)-2) BETWEEN @startRef AND (@startRef + @endRef)))
END
RETURN

I have an SqlDataSource that uses a value from the query string in the WHERE clause of the sql statement.
The sql is something like this:
SELECT * FROM myTable WHERE myfield = @myfield
and I have the QueryStringParameter setup like this:
<asp:QueryStringParameter Name="myfield" QueryStringField="myfield" />
What I need is for the sql statement to return all records in the case that "myfield" is not defined in the query string.
How would I implement this?

Hello all, my update statement works as expected, but lacks some conditional logic. How can I change the statement to not decrement qtyonhand if the quantity is 0? Additionally, I would need to return to the calling application something that would allow me to populate a label with a message to the user.. How can that be accomplished?
Here is my sproc:CREATE PROCEDURE [webuser].[cssp_removeItem]
@lblID int
AS
Update cstb_inventoryset qtyonhand = qtyonhand -1where Id = @lblIDGO
Here is my app code:
Try
Dim cmd As SqlCommand = cn.CreateCommand
cmd = New SqlCommand("cssp_removeItem", cn)
cmd.CommandType = CommandType.StoredProcedure
With cmd
cmd.Parameters.Add("@lblId", SqlDbType.Int).Value = lblId.Text
End With
If Not cn.State = ConnectionState.Open Then
cn.Open()
End If
cmd.ExecuteNonQuery()
Catch ex As Exception
Response.Write(ex.ToString)

Hi,
[SQL 2005 Express]
I would like a DropDownList to be populated differently depending on the selected value in a FormView.
If the FormView's selected value (CompanyID) is 2, then the DropDownList should show all Advisers from the relevant Company. Otherwise, the DropDownList should show all Advisers from the relevant Company where the TypeID field is 3.
Here is the SQL for case 1:
SELECT AdviserID, AdviserName FROM Advisers WHERE (CompanyID = @CompanyID).
Here's the SQL for case 2:
SELECT AdviserID, AdviserName FROM Advisers WHERE (CompanyID = @CompanyID) AND (TypeID = 3).
Here's my best (failed) attempt to get what I want:
SELECT AdviserID, AdviserName FROM Advisers WHERE IF @CompanyID = 2 THEN BEGIN (CompanyID = @CompanyID) END ELSE BEGIN (CompanyID = @CompanyID) AND (TypeID = 3) END
I've also tried:
SELECT AdviserID, AdviserName FROM Advisers WHERE CASE @CompanyID WHEN 2 THEN (CompanyID = @CompanyID) ELSE (CompanyID = @CompanyID) AND (TypeID = 3) END
and
SELECT AdviserID, AdviserName FROM Advisers WHERE CASE WHEN (@CompanyID = 2) THEN (CompanyID = @CompanyID) ELSE (CompanyID = @CompanyID) AND (TypeID = 3) END
I'd be very grateul to know (a) what the correct syntax for this is and (b) if it can be achieved using a parametised query, rather than a stored procedure.
Thanks very much.
Regards

Hello Folks,
Well I've hit the wall on this one:
I'm wondering if one can designate a conditional foreign key that relates to one of many different tables depending on the "type" column in the foreign key's. My goal is to come up with some SQL code that will allow for this in a Create table statement. (By the way I'm using MS SQL-7 but I'm wondering if this can be done in general.)
I have two simple cases below that show illustrate what I'm trying to do:
Thanks in advance, -JerryZZ
---------------------------------------------------------
Case 1: The foreign key relation is to a primary key
Table: Invoices
-Fields:
---InvoiceID ..... (primary key)
---BilleeID ...... (fkey to Manfacturers.ManfID IF BilleeType=M)
...................(fkey to Distibutors.DistID IF BilleeType=D)
---BilleeType .....(constraint = M or D)
Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---CompanyName.. (not null)
Table: Distributors
-Fields:
---DistID ........ (primary key)
---CompanyName .. (not null)
---------------------------------------------------------
Case 2: The foreign key relation is to a unique "not null" non-primary key
Table: InvoicesEmail
-Fields:
---InvoiceID ..... (primary key)
---EmailAddress .. (fkey to Manfacturers.EmailAddress IF BilleeType=M)
...................(fkey to Distibutors.EmailAddress IF BilleeType=D)
---BilleeType .....(constraint = M or D)
Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---EmailAddress .. (unique, not null)
Table: Distributors
-Fields:
---DistID ........ (primary key)
---EmailAddress .. (unique, not null)
---------------End-O-Message-------------------------------------

Hi, ladies and gentelmen!
Can you help me with following trouble:
I got a table (let it be called SomeTable) in which there's one nullable field (let's call it SomeField) among many others. PRIMARY KEY for SomeTable is of INT IDENTITY type.
Business rules are following: only records that have SomeField IS NULL can be deleted, so I need to perform conditional delete (for cases like DELETE SomeTable). I don't like idea about using SP here, so I tried to solve the task by means of trigger. However, when DELETE clause is used within a transaction and there're records affected by the trigger that don't match business rule, trigger uses ROLLBACK TRAN and then deletes only matching rows from target table. Everything works fine with our SomeTable, but not so fine with the transaction, because due to ROLLBACK TRAN statement in trigger body this transaction is rolled back (as it is described in documentation). But I don't wanna ALL my transaction rolled back! So, is there in SQL Server 7.0 any way to rollback only changes that caused trigger to fire? Something like ROLLBACK TRIGGER?

I would like to write the following (pseudo) stored procedure, but am having problem with the syntax:
Create Procedure spSort
@IDContract nvarchar(10)
@SortOrder int
SELECT * FROM Contracts
WHERE IDContract = @IDContract
IF @SortOrder = 0
BEGIN
ORDER BY ContractDate
END
IF @SortOrder = 1 THEN
BEGIN
ORDER BY ShippingPeriod
END
The problem is in conditionally setting the sort order. The actual sp is quite complex and I don't really want to have to use two procedures (one for ordering by ShippingPeriod and one for ordering by ContractDate
Any suggestions please?
Many thanks

Hi,
Originally had 2 tables, fullsource and ssotarget. I did the following extract on fullsource due to its irregular schema and inserted into ssotarget:
INSERT SSOTARGET (pin, address1, address2, address3, MemberNo, Tel1, Tel2, Tel3, Tel4, DOB, Email, IDNumber, Title, Initials, Firstname, Surname, STATUS)
SELECT
PIN,
MAX(CASE WHEN HEADER = 'ADDRESS DETAILS' AND PROPERTY = 'LINE 1' THEN VALUE ELSE NULL END) AS address1,
MAX(CASE WHEN HEADER = 'ADDRESS DETAILS' AND PROPERTY = 'LINE 2' THEN VALUE ELSE NULL END) AS address2,
MAX(CASE WHEN HEADER = 'ADDRESS DETAILS' AND PROPERTY = 'LINE 3' THEN VALUE ELSE NULL END) AS address3,
MAX(CASE WHEN HEADER = 'ACOMPANY' AND PROPERTY = 'Membership Number' THEN VALUE ELSE NULL END) AS MemberNo,
MAX(CASE WHEN HEADER = 'CONTACT DETAILS' AND PROPERTY = 'Preferred method of contact*' THEN VALUE ELSE NULL END) AS Tel1,
MAX(CASE WHEN HEADER = 'CONTACT DETAILS' AND PROPERTY = 'Tel number (o/h) e.g. 011 2690000' THEN VALUE ELSE NULL END) AS Tel2,
MAX(CASE WHEN HEADER = 'CONTACT DETAILS' AND PROPERTY = 'Mobile number e.g. 0821234567' THEN VALUE ELSE NULL END) AS Tel3,
MAX(CASE WHEN HEADER = 'CONTACT DETAILS' AND PROPERTY = 'Fax number e.g. 011 2691000' THEN VALUE ELSE NULL END) AS Tel4,
MAX(CASE WHEN HEADER = 'Date Of Birth' AND PROPERTY = 'eg. 04 Jan 1965' THEN VALUE ELSE NULL END) AS DOB,
MAX(CASE WHEN HEADER = 'Email address' AND PROPERTY = 'Email Address' THEN VALUE ELSE NULL END) AS Email,
MAX(CASE WHEN HEADER = 'ID Number' AND PROPERTY = 'ID Number' THEN VALUE ELSE NULL END) AS IDNumber,
MAX(CASE WHEN HEADER = 'Member Information' AND PROPERTY = 'Title' THEN VALUE ELSE NULL END) AS Title,
MAX(CASE WHEN HEADER = 'Member Information' AND PROPERTY = 'Initials' THEN VALUE ELSE NULL END) AS Initials,
MAX(CASE WHEN HEADER = 'Member Information' AND PROPERTY = 'Firstname' THEN VALUE ELSE NULL END) AS Firstname,
MAX(CASE WHEN HEADER = 'Member Information' AND PROPERTY = 'Surname' THEN VALUE ELSE NULL END) AS Surname,
MAX(CASE WHEN HEADER = 'ACOMPANY' AND PROPERTY = 'Membership Number' THEN STATUS ELSE NULL END) AS STATUS
FROM
FULLSOURCE
GROUP BY PIN
Now how can I reverse this to insert all the values back to tbl FULLSOURCE from maybe an updated SSOTARGET Tbl. FULLSOURCE looks like this:
SELECT [PIN]
,[SYSTEM]
,[Header]
,[Property]
,[Value]
,[Status]
,[ID_Header]
,[ID_Property]
FROM [fullsource]

I am trying to write query that will select calls that only show up when the resolution returned from the case in the sub query is 'y'. When I do the group by some calls will show up twice because of a null and a 'y' resolution return. I want to only select a call if there is a 'y' that shows for all resolutions associated with that call. If there are any null resolutions for the call I don't want it to show up in my returned values. This is what I have so far, but I can't figure out how to make it drop both instances of the callID if one instance is null.
Code:
SELECT C.CallID, P.PrimarySupportGroupID, P.PrimaryTeamName, T1.Resolution, CASE C.CallID WHEN T1.Resolution IS NOT NULL THEN 'Y' ELSE 'N' END
FROM HEAT.dbo.CallLog C,
(SELECT CallID, CASE WHEN A1.Resolution = '' THEN 'Y' ELSE NULL END AS Resolution
FROM HEAT.dbo.Asgnmnt A1) T1, HEAT.dbo.Profile P
WHERE C.CallID = T1.CallID AND C.CustID = P.CustID AND (P.PrimarySupportGroupID = 'ATS') AND (P.PrimaryTeamName = 'Beta')
GROUP BY C.CallID, P.PrimarySupportGroupID, P.PrimaryTeamName, T1.Resolution
If anyone could help me out with this or at least give me a little information and point me in the right direction I would really appreciate it.
Thank you

Select field, field2, Count(if Field3 > 0)
(i know this code will not work)
The idea is to only count records if they have a value greater than zero

I have a trigger that updates values in a table when col2 is updated by a stored procedure.
I'd like to make this a conditonal trigger to prevent negative values from being inserted in the table. I'm not familiar with the syntax of triggers enough to get this to work and I've search for a reference with no luck.
Here's the current trigger code:
Code:
FOR INSERT, UPDATE
AS
UPDATE table1
SET col4= col1 - col2 - col3
I need to evaulate (col1 - col2 - col3) to see if it's less than zero. If it is, I want to set col4=0.
This is what I've tried, but it doesn't work. Any help is appreciated:
Code:
FOR INSERT, UPDATE
AS
select col1, col2, col3 from table1
if (col1 - col2 - col3) < 0
UPDATE table1
SET col4 = 0
else
UPDATE table1
SET col4= col1 - col2 - col3

I need to do a conditional insert. This is what I have tried, it does not work.
What am I doing incorrectly?
IF (SELECT COUNT(*) FROM TBL1 INNER JOIN
TBL2 ON TBL1.MODEL_ID = TBL2.MODEL_ID INNER JOIN
TBL3 ON TBL1.PRO_TYPE = TBL3.TYPE INNER JOIN
TBL4 ON TBL1.PRO_SITE = TBL4.WHDESC) > 0
INSERT INTO TBL5
SELECT TBL1.PRO_SITE, TBL1.MODEL_ID,
TBL1.NUM_SLOTS, TBL1.TARGET_DAYS, GETDATE() AS Expr1,
TBL3.TYPE_ID, NULL AS Expr2, TBL1.NUM_SLOTS AS Expr3, NULL AS Expr4, NULL
AS Expr5, 0 AS RAMP
FROM TBL1 INNER JOIN
TBL2 ON TBL1.MODEL_ID = TBL2.MODEL_ID INNER JOIN
TBL3 ON TBL1.PRO_TYPE = TBL3.TYPE INNER JOIN
TBL4 ON TBL1.PRO_SITE = TBL4.WHDESC
UPDATE TBL5
SET TEAMS=0
GO
UPDATE TBL5
SET TEAMS = (SELECT NUM_SLOTS
FROM TBL6 R1
WHERE (R1.TEAM_ID = TBL5.TEAM_ID)
)
WHERE (TEAM_ID =
(SELECT TEAM_ID
FROM TBL6 R3
WHERE (R3.TEAM_ID = TBL5.TEAM_ID)))
GO
UPDATE TBL5
SET TOTALTEAMS = TEAMS + RAMP
GO
I need to do a conditional because sometimes the select that returns data contains no records.
Thanks...

Hi, I've been handed a task at work where I need to use SQL triggers to solve the problem.
I need to be able to run a Trigger when, and only when, a cell in a specific column in a row changes to a specific value.
For instance, say I have the following table:
CREATE TABLE source
(
ID tinyint NOT NULL,
contacttype tinyint NOT NULL,
)
If one of the rows is UPDATE'd to contacttype = 2, I want to fire a trigger, but not if it changes to anything else.
How can this be performed?
