An Easy Way To Reference The Nth Row From A Table Meeting A Condition X, And The Mth Row From The Same Table Meeting Condition Y
Hi
I am developing a scientific application (demographic forecasting) and have a situation where I need to update a variety of rows, say the ith, jth and kth row that meets a particular condition, say, x.
I also need to adjust rows, say mth and nth that meet condition , say y.
My current solution is laborious and has to be coded for each condition and has been set up below (If you select this entire piece of code it will create 2 databases, each with a table initialised to change the 2nd,4th,8th and 16th rows, with the first database ignoring the condition and with the second applying the change only to rows with 'type1=1' as the condition.)
This is an adequate solution, but if I want to change the second row meeting a second condition, say 'type1=2', I would need to have another WITH...SELECT...INNER JOIN...UPDATE and I'm sure this would be inefficient.
Would there possibly be a way to introduce a rank by type into the table, something like this added column which increments for each type:
ID
Int1
Type1
Ideal Rank by Type
1

The solution would then be a simple update based on an innerjoin reflecting the condition and rank by type...
I hope this posting is clear, albeit long.
Thanks in advance

Recurring Meeting On Multiple Days UGH!
Ugh! I need to create some SQL that will generate all the dates for a recurring meeting on multiple days per week. For example: a meeting on Monday , Wednesday and Friday at 10:00 am - 10:30 am from December 1st 2004 to Feb 28th 2005. I'm not sure what to do here. Any Ideas? Regards Russ

Repost!: Extract Data Meeting Specific Criteria.
Here’s a more in depth breakdown of my problem: We have 4 regions, currently we only have 3 servers in the field, and therefore only 3 regional id’s are being used to store the actual data of the pbx. The central server (RegionalID = 0) is holding the data for itself and the 4th region until the new server is deployed. It now has to be deployed and therefore the data migration for this region has to take place. I am trying to extract all the data for this 4th region (RegionalID= 1) from the central server database from all the relevant tables. When doing this I will firstly, have to check that the CallerID is valid, if it is not valid, then check that RegionalDialup = ‘0800003554’ which is the dialup number for this 4th region (RegionalID = 1). I have a table named lnkPBXUser which contains the following: RegionalID pbxID userID 0 1012 17 0 543 2 0 10961 6 0 16499 26 0 14061 36 0 15882 2 4 15101 6 4 15101 26 6 16499 2 6 16012 26 I have a table named tblDialupLog which has 20 columns, I have selected only the columns I am interested in (below): PBXIDDailupDT DongleAccessNum CLI RegionalID RegionalDialup 838/8/2006 8:58:11 AM T2 UQ 28924 013249370000800003554 5438/8/2006 8:55:44 AM T0 UA 33902 012362350000800003554 12198/8/2006 8:59:03 AM T3 ZD 02031 015295809500800003554 10128/8/2006 9:02:54 AM T0 UA 41261 017301105000800003554 13318/8/2006 8:59:57 AM T0 UA 01938 012460462700800003554 19798/8/2006 9:02:52 AM T0 UA 09836 016375121000800003554 19038/8/2006 8:58:41 AM T0 UA 26009 014717535600800003554 15228/8/2006 8:58:54 AM T3 MB 94595 057391287100800004249 3198/8/2006 8:51:28 AM T2 ZD 32892 054337510000800004249 32708/8/2006 9:04:26 AM T2 MB 8733100800004249 I have a table named tblCodes, it contains all regions but I only need to select the codes for RegionalID 1 : CodeIDRegionalID ExtName SubsNDCDLocCDUpdateStatusRegionDesc 79731 PRETORIA 0123620NORTH EASTERN REGION 79741 HARTEBEESHOEK 012 30120NORTH EASTERN REGION 79751 HARTEBEESHOEK 01230130NORTH EASTERN REGION 79761 PRETORIA 01730140NORTH EASTERN REGION 79771 PRETORIA 01230150NORTH EASTERN REGION I have a table named tblDongleArea which contains the following (below only shows dongle area codes for the fourth region( RegionalID = 1): AreaIDRegionalIDDongleAreaCodeAreaDescUpdateStatus 121UAOumashoop0 131UBPietersburg0 141UCWarmbad01 151UDNylstroom0 161UEPotgietersrus0 271UFLouis Trichardt0 281UGMessina0 291UHEllisras0 301UIThabazimbi0 311UJPhalaborwa0 321UKTzaneen0 331UTStanderton0 341UMMeyerton0 351UNNelspruit0 361UOWitrivier0 371UPLydenburg0 381UQMiddelburg0 391URWitbank0 401USBronkhorstspruit0 461UZOlifantsfontein0 I have a table named tblRegionalNumbers which contains the following, as you can see the RegionalDialup for the fourth region = 0800003554: RegionalID RegionalDialupRegionUpdateStatusRegionCodeLocalRegion 10800003554North Eastern010 20800005027Gauteng020 30800006194Eastern030 40800004249Central040 50800201859Southern050 60800201989Western060 70800113515HO101 80800222204Tellumat070 Ok, I am dealing with the lnkPBXUser table at the moment, I need to be able to join lnkPBXUser and tblDialupLog, then compare tblDialupLog.CLI to tblCodes.SubsNDCD + tblCodes.LocCD (when these two columns are concatenated the result will only be a substring of tblDialupLog.CLI. (this is to make sure that the CLI exists in tblCodes.) If it does exist, then it is part of the fourth region and should be returned in the result set. If it does not exist, I then need to check that tblDongle.DongleAreaCode is a substring of tblDialupLog.DongleAccessNumber. If it is a valid DongleAreaCode for that region, then it is part of the fourth region and should be returned in the result set. If it does not exist, I then need to check that tblDialupLog.RegionalNumber = ‘080003554’. So from the above tables an expected result would be: RegionalID pbxID userID 0 1012 17 0 543 2 Please assist, it would be greatly appreciated. Regards SQLJunior

One Table, Two Condition, Display Result As One Table
I got one table with 3 columns = Column1, Column2, Column3 Sample Table Column1 | Column2 | Column3 ------------------------------------ A | 12 | 0 A | 13 | 2 B | 12 | 5 C | 5 | 0 Select Column1, Column2, Column3 as New1 Where Column1 = A AND Column2 = 12 AND Column3 = 0 Select Column1, Column2, Column3 as New2 Where Column1 = A AND Column2 = 12 AND Column3 >0 The only difference is one condition Column3 = 0 and another one Column3 > 0. This two condition is not an "AND" condition... but just two separate information need to be display in one table. So how do i display the result in one table where the new Output will be in this manner Column1 | Column2 | New1 | New2| Thanks

Create Table On Condition
I import CSV file into MSSQL database table twice a day using DTS. There is a filed name clients, which contains clients name. I import all data from CSV file to temp table, from temp table it goes to every single clients table. Client A, B and C has separate tables in database as tableA, tableB and tableC. Problem is that when there is a new client in the CSV file I need to create a table for new client in database manually. I am in need of a script which check for new client entry in CSV file and compare it in clients table. If incoming client is not present in client's table locally then then script should create a new table for new incoming client, automatically. Thanx. Waiting for someones response !

Select Condition From Log Table
Hi guys Im not even sure how to word this right, but how do I compare one element(unsure word number 1) namely Filename, from a list of results, and use that value as a variable for another condition in the same select... I think?! So if I get a list of 50 filenames (from a log table), some might be double. If the file was successfully processed, it will log that filename and the status as OK and if not then BAD. The file will be modified and then reprocessed until OK. Each time the file was processed, it will log the filename and status. I then run a statement that shows all the files that were BAD (from the log table) and it will bring up then filename and BAD status. What I want to do is check the status' and if the file is BAD, check if there is another logged entry with that filename and status is OK, if found then not produce output as Im only looking for the files that status' are BAD with no OK status for any of the logged entries for that filename. Is that understandable? If not then Ill try reword it. The help is much appreciated! Justin

COndition Spli - Error Date Condition
Dear friends, I'm having a problem... maybe it's very simple, but with soo many work, right now I can't think well... I need to filter rows in a dataflow... I created a condition spli to that... maybe there is a better solution... And the condition is: Datex != NULL(DT_DATE) (Some DATE != NULL) [Eliminar Datex NULL [17090]] Error: The expression "Datex != NULL(DT_DATE)" on "output "Case 1" (17123)" evaluated to NULL, but the "component "Eliminar Datex NULL" (17090)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error. What is wrong?? Regards, Pedro

Insert Into Temp Table Based On If Condition
hello all,this might be simple:I populate a temp table based on a condition from another table:select @condition = condition from table1 where id=1 [this will giveme either 0 or 1]in my stored procedure I want to do this:if @condition = 0beginselect * into #tmp_tablefrom products pinner joinsales s on p.p_data = s.p_dataendelsebeginselect * into #tmp_tablefrom products pleft joinsales s on p.p_data = s.p_dataendTha above query would not work since SQL thinks I am trying to use thesame temp table twice.As you can see the major thing that gets effected with the condictionbeing 0/1 is the join (inner or outer). The actual SQL is much biggerwith other joins but the only thing changing in the 2 sql's is the joinbetween products and sales tables.any ideas gurus on how to use different sql's into temp table based onthe condition?thanksadi

How To Make Table Row Invisible Based On Certain Condition
HI I have the following scenario in my report. -The data is displayed in a table -The table groups by one field -Each table row calls a subreport -There is about 6 paramaters in the report -The last paramater of the list of paramters is a multivalue paramater and based on what is selected in the list the corresponding subreport must be shown. -So i use a custom vbscript funtion to determine if a specific value was selected or not. This functionality is working fine. My problem is if the user does not select all the values in the multi select then i want to make the row invisble and remove the whitespace so that there is not a gap between the other subreports which is shown. I can make the subreport invisible inside the row but there is still the white space which does not display very nicly. How can i make the row invisible if the vbscript function that is called returns a false value? Here is the funtion I call -> Code.InArray("ValueToSearchFor", Parameters!MultiValueDropDown.Value) The Function returns a true or false. Thanks.

Trying To Create A Proc That Will Insert Values Based On A Condition That Is Another Table
Can someone give me a clue on this. I'm trying to insert values based off of values in another table. I'm comparing wether two id's (non keys in the db) are the same in two fields (that is the where statement. Based on that I'm inserting into the Results table in the PledgeLastYr collumn a 'Y' (thats what I want to do -- to indicate that they have pledged over the last year). Two questions 1. As this is set up right now I'm getting NULL values inserted into the PledgeLastYr collumn. I'm sure this is a stupid syntax problem that i'm overlooking but if someone can give me a hint that would be great. 2. How would I go about writing an If / Else statement in T-SQL so that I can have the Insert statement for both the Yes they have pledged and No they have not pledged all in one stored proc. I'm not to familar with the syntax of writing conditional statements within T-SQL as of yet, and if someone can give me some hints on how to do that it would be greatly appriciated. Thanks in advance, bellow is the code that I have so far: RB Select Results.custID, Results.PledgeLastYr From Results, PledgeInLastYear Where Results.custID = PledgeInLastYear.constIDPledgeInLastYear Insert Into Results(PledgeLastYr) Values ('Y')

Update Statement Performing Table Lock Even Though Where Condition On Clustered Primary Index?
Hi All,I have a database that is serving a web site with reasonably hightraffiic.We're getting errors at certain points where processes are beinglocked. In particular, one of our people has suggested that an updatestatement contained within a stored procedure that uses a wherecondition that only touches on a column that has a clustered primaryindex on it will still cause a table lock.So, for example:UPDATE ORDERS SETprod = @product,val = @valWHERE ordid = @ordidIn this case ordid has a clustered primary index on it.Can anyone tell me if this would be the case, and if there's a way ofensuring that we are only doing a row lock on the record specified inthe where condition?Many, many thanks in advance!Much warmth,Murray

The data is like this: Sequence ItemCode IsParent 1 XYZ 0 'do not have child record 2 PQR 1 'have child records with sequence no 3 3 ASD 0 3 AFDGE 0 3 VDC 0 4 ASR 1 'have child records with sequence no 5 5 ASR 0 If IsParent = 1, that record has child records with sequence = parent sequenece + 1 I think u can understand the data I need to bind, and it is like: XYZ + PQR ASD AFDGE VDC ASR On + click we can do show/hide of child records. I m not getting how to achive this in SQL server report. Can u give some hint? Thanks in advance Pravin

Condition (if / Else) In SQL?
Hi all,I'm building a DataSet on Visual Studio and don't know how to do a condition (if/else) with SQL... I have a search form, with a DropDownList and have 2 options in it: Search by Title or Search by Author. If the "Title" is selected, then the value is "title and if "Author" is selected, then the value is "author".Here is what I have right now for the DataSet, as seperated queries but I think I can combine them to be one single query 1.This will returns the songs that matches the title:SELECT LYRICS_PK, LYRICS_TITLE, LYRICS_TITLE2, LYRICS_WRITER, LYRICS_WRITER2, LYRICS_COWRITER, LYRICS_DATE_ADDED, UserId_FK, LYRICS_APPROVED, LYRICS_TYPE, LYRICS_VIEWS, LYRICS_ADDED_BYFROM t_lyricsWHERE ((@LYRICS_TITLE IS NULL) OR (LYRICS_TITLE LIKE '%' + @LYRICS_TITLE + '%') OR (LYRICS_TITLE2 LIKE '%' + @LYRICS_TITLE + '%')) AND (@LYRICS_TYPE = 'title') 2. This returns the songs that matches the author: SELECT LYRICS_PK, LYRICS_TITLE, LYRICS_TITLE2, LYRICS_WRITER, LYRICS_WRITER2, LYRICS_COWRITER, LYRICS_DATE_ADDED, UserId_FK, LYRICS_APPROVED, LYRICS_TYPE, LYRICS_VIEWS, LYRICS_ADDED_BY FROM t_lyrics WHERE ((@LYRICS_AUTHOR IS NULL) OR (LYRICS_AUTHOR LIKE '%' + @LYRICS_AUTHOR + '%') OR (LYRICS_AUTHOR2 LIKE '%' + @LYRICS_AUTHOR + '%')) AND (@LYRICS_TYPE = 'author') This is very inefficient because I have 2 queries, and I need to build 2 ObjectDataSources as well as 2 different GridViews to display the results. I think we can do something likeSELECT .... ... FROM t_lyricsif (@LYRICS_TYPE = 'title') DO THE WHERE CLAUSE THAT RETURNS MATCHES WITH TITLEelse if (@LYRICS_TYPE = 'author') DO THE WHERE CLAUSE THAT RETURNS MATCHES WITH AUTHOR But I don't know how to write that in T-SQL.Any help would be greatly appreciated,Thank you very much,Kenny.

And / Or Condition
hi, i'm working on a query and have discovered something fairly simple regarding "and" / "or" condition. if I use e.g. id_product in ('1111','2222') as a result i should get all products that match id = 1111 and id = 2222. But if I do it like id_product in ('1111') and id_product in ('2222') as a result i get 0 rows returned, where as i want to find invoices that have both products, and not those which have either product 1111 or 2222 or even both :) thank you for any suggestions!

SQL Query Condition
Hi, I am creating a stored procedure which takes a few paramaters. One of which is a string of comma separated codes. At the end of my select query the codes will be used in the where clause. What I'm doing is parsing the comma separated string and populating a temp table called #codes. So my query will look something like this: select * from tableA where tableA.col1 = 'something' and tableA.code in (select * from #codes) and.... However, the code paramater can be null and if this is the case I want the query to be called for all codes - i.e. I effectively want to remove the and tableA.code in (select * from #codes) part of the where clause. Is there any clever way of doin this other than having a if... else... and writing 2 queries - one with the and and one without it? Hope this is clear. Thanks, Wallace

Where Condition Using Variable
Hi, I've come across a funny when using variables within a WHERE clause in a multiple JOIN statement. I have the following tables: Articles table ============== Article_ID int PK IDENTITY(1,1) Title varchar(128) Article_Date datetime Author_ID int FK REFERENCES Authors(Author_ID) Archive char(1) WaitingForConfirm char(1) Authors table ============= Author_ID int PK IDENTITY(1,1) Author_Name varchar(64) TextArticles table ================== ContentRow_ID int PK IDENTITY(1,1) Article_ID int FK references Articles(Article_ID) Content varchar(2048) Below is an extract from a fairly complex stored procedure used to search based on a variable number of values including Author, Title and Content. SELECT Articles.Article_ID , Articles.Title , Articles.Article_Date , Authors.Author_Name FROM Articles LEFT OUTER JOIN Authors ON Articles.Author_ID = Authors.Author_ID LEFT OUTER JOIN TextArticles ON Articles.Article_ID = TextArticles.Article_ID LEFT OUTER JOIN FileArticles ON Articles.Article_ID = FileArticles.Article_ID WHERE Articles.Article_Date BETWEEN @startdate AND @enddate AND (Articles.Archive > 'Y' OR Articles.Archive < 'Y') AND (Articles.WaitingForConfirm > 'Y' OR Articles.WaitingForConfirm < 'Y') AND Articles.Title LIKE @title AND authors.author_name LIKE @author AND TextArticles.Content LIKE @content ORDER BY Articles.Article_Date DESC If any of these variables are passed in as NULL I convert to '%' and any variable that is not null is altered to '%value%'. The problem arises with the @content variable - which is varchar(128). The following variables are passed in: @startdate = 'JAN 01 2000' @enddate = GETDATE() @author = 'smith' - which is changed within the procedure to '%smith%' @title = NULL - which is changed within the procedure to '%' @content = NULL - which is changed within the procedure to '%' The procedure returns 0 rows based on these criteria - even though if I hard- code these values the expected number of rows are returned. I have used various print statements throuout the procedure and the @content variable is always correctly established. I have come across this before with another table/column/join combination and am at a loss to explain it. Any help would be greatly appreciated. Many Thanks . . Greg

Stuck With OR Condition
Hi, I have a sql problem I'm trying to solve. I'm selecting from a table based on a foreign key, and the select returns 2 rows. The table has a column called type, and each row for the foreign key has a different type value. Hopefully the example below can help to explain: Case 1: PK | FK | Type | Text -------------------------- 1 | 226 | 0 | some text goes here 2 | 226 | 1 | NULL Case 2: PK | FK | Type | Text -------------------------- 3 | 334 | 0 | some text goes here 4 | 334 | 1 | actual text I want to select is in this cell I'm trying to create a select statement to grab the text for the foreign key I'm looking up. In case 2, I want the text where type=1 but in case 1 I want the text where type=0. I had started writing it as select text from table where fk=334 and ( (type=4 and text is not null) or type=0 ) but this returns both rows. What I what is something that I think is more akin to case a || case b expression in programming - if case a evaluates as true, use that, otherwise evaluate case b and use if true, otherwise return false. I hope you can understand what I'm trying to get and any suggestions would be much appreciated. Thanks in advance, Peter
