• Using a RegEx in a SQL Query

  - by Jim B

  Hey Everyone, Here's the situation I'm in: We have a field in our database that contains a 3 digit number, surrounded by some text. This number is actually a PK in another table, and I need to extract this out so I can implement a proper FK relationship. Here's an example of what would currently reside in the column: Some Text Goes Here - (305) Followed By Some More Text So, what I'm looking to do is extract the '305' from the column, and hopefully end up with a result that looks something like this (pseudo code) SELECT <My Extracted Value>, Original Column Text, Id FROM dbo.MyTable It seems to me that using a Regex match in my query is the most effective way to do this. Can anybody point me in the right direction?

• SQL Server stored procedure + set error message from the records of a table

  - by lucky

  Hello, My question is I have a table with the set of records. I am calling a stored procedure for some other purpose. But when ever it finds some duplicate records. It need to return as error message back to php. C1 C2 c3 abc 32 21.03.2010 def 35 04.04.2010 pqr 45 30.03.2010 abc 12 04.05.2010 xyz 56 01.03.2010 ghi 21 06.05.2010 def 47 17.02.2010 klm 93 04.03.2010 xyz 11 01.03.2010 For the above set it need to check for the records that has the same c1. The stored procedure should return as abc,def,xyz are duplicate. I tried something like this. This will not work it has more than 1 set of duplicate records. Please help me to enhance this to solve the purpose. SET @duplicate = (SELECT c1 FROM temp GROUP BY c1 HAVING count(c1) > 1) --Check for duplicate concession Nr. IF(len(@duplicate) > '1') BEGIN SET @error = @error + ' Duplicate C1 Number:- ' + @duplicate SET @errorcount = @errorcount + 1 END As this one type error I am checking for errorcount. IF @errorcount <> '0' BEGIN GOTO E_General_Error END -- If an error occurs, rollback and exit E_General_Error: PRINT 'Error' SET @error = @error IF @@error <> 0 SET @error = 'Database update failed' ROLLBACK TRANSACTION update_database RETURN END Now it is able to return Duplicate c1 number abc. If there are more than 1 problem comes. Thanks in advance!

• code duplication in sql case statements

  - by NS

  Hi I'm trying to output something like the following but am finding that there is a lot of code duplication going on. | australian_has_itch | kiwi_has_itch | | yes | no | | no | n/a | | n/a | no | ... My query looks like this with two case statements that do the same thing but flip the country (my real query has 5 of these case statements): SELECT CASE WHEN NOT EXISTS ( SELECT person_id FROM people_with_skin WHERE people_with_skin.person_id = people.person_id AND people.country = "Australia" ) THEN 'N/A' WHEN EXISTS ( SELECT person_id FROM itch_none_to_report WHERE people.country = "Australia" AND person_id = people.person_id ) THEN 'None to report' WHEN EXISTS ( SELECT person_id FROM itchy_people WHERE people.country = "Australia" AND person_id = people.person_id ) THEN 'Yes' ELSE 'No' END australian_has_itch, CASE WHEN NOT EXISTS ( SELECT person_id FROM people_with_skin WHERE people_with_skin.person_id = people.person_id AND people.country = "NZ" ) THEN 'N/A' WHEN EXISTS ( SELECT person_id FROM itch_none_to_report WHERE people.country = "NZ" AND person_id = people.person_id ) THEN 'None to report' WHEN EXISTS ( SELECT person_id FROM itchy_people WHERE people.country = "NZ" AND person_id = people.person_id ) THEN 'Yes' ELSE 'No' END kiwi_has_itch, FROM people Is there a way for me to condense this somehow and not have so much code duplication? Thanks!

• sql stored procedure in visual studio 2008

  - by Greg

  Hi, I want to write stored procedure in visual studio that as a parameter recieves the name of project and runs in database TT and copies data from TT.dbo.LCTemp (where the LC is the name of the project recieved as a parameter) table to "TT.dbo.Points" table. both tables have 3 columns: PT_ID, Projectname and DateCreated I think I have written it wrong, here it is: ALTER PROCEDURE dbo.FromTmpToRegular @project varchar(10) AS BEGIN declare @ptID varchar(20) declare @table varchar(20) set @table = 'TT.dbo.' + @project + 'Temp' set @ptID = @table + '.PT_ID' Insert into TT.dbo.Points Select * from [@table] where [@ptID] Not in(Select PT_ID from TT.dbo.Points) END Any idea what I did wrong?

• SQL: how to get the left 3 numbers from an int

  - by dmr

  I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

• deleting and reusing a temp table in a stored precedure

  - by Sheagorath

  Hi I need to SELECT INTO a temp table multiple times with a loop but I just can't do it, because after the table created by SELECT INTO you can't simply drop the table at the end of the loop, because you can't delete a table and create it again in the same batch. so how can I delete a table in a stored procedure and create it again? is it possible to this without using a temp table? here is a snippet of where I am actualy using the temp table which is supposed to be a pivoting algorithm: WHILE @offset<@NumDays BEGIN SELECT bg.*, j.ID, j.time, j.Status INTO #TEMP1 FROM #TEMP2 AS bg left outer join PersonSchedule j on bg.PersonID = j.PersonID and bg.TimeSlotDateTime = j.TimeSlotDateTime and j.TimeSlotDateTime = @StartDate + @offset DROP TABLE #TEMP2; SELECT * INTO #TEMP2 FROM #TEMP1 DROP TABLE #TEMP1 SET @offset = @offset + 1 END

• How to implement multi relationship in SQL Server?

  - by Ethan

  I’m trying to design a database to use with ASP.net MVC application. Here is the scenario: There are three entities and users can post their comments for each of these different entities. I just wonder how just put one table for Comments and link all other entities to it. Obviously, Comments table needs 3 references (foreign key) to those tables but as you know these foreign keys can’t be null and just one of them can be filled for each row. Is there any better way than implementing three different tables for each entity’s comments?

• Clean up State field with T-SQL?

  - by Pselus

  The State field in our database is a mess. There was no validation when it was filled so we have everything from two letter abbreviations to full state names to misspelled state names to "test" and "xxxx", etc. I am not going to try to handle everything, but for sure I want to fix the correct state names to abbreviations. I have a list of valid state names and abbreviations, but I don't know how I can do this: UPDATE Table SET State = ('AR','AK') WHERE (SELECT * FROM Table WHERE State IN ('Arkansas','Alaska')) Basically, can I update a field to be something from a list by the location it is in another list?

• SQL Server: Mitigating schema changes/upgrades

  - by bradhe

  I haven't spent a ton of time researching this yet, mostly looking for best practices on upgrading/changing DB schemas. We're actively developing a new product and as such we often have additions or changes to our DB schema. We also have many copies of the DB -- one for the test environment, one for the prod environment, dev environments, you name it. We don't really want to have to blow away test data every time we want to make a change to the DB. Are there good ways of automating this or handling this? None of us have really ever had to deal with this so...

• sql select with exact outcome

  - by Shiro

  Asking a simple question, just want everyone have fun to solve it. I got 2 tables. 1. Student 2. Course Student +----+--------+ | id | name | +----+--------+ | 1 | User1 | | 2 | User2 | +----+--------+ Course +----+------------+------------+ | id | student_id | course_name| +----+------------+------------+ | 1 | 1 | English | | 2 | 1 | Chinese | | 3 | 2 | English | | 4 | 2 | Japanese | +----+------------+------------+ I would like to get the result all student, who have taken English and Chinese, NOT English or Chinese. Expected result: +----+------------+------------+ | id | student_id | course_name| +----+------------+------------+ | 1 | 1 | English | | 2 | 1 | Chinese | +----+------------+------------+ What we normally do is select * from student join course on (student.id = course.student_id) WHERE course_name = 'English' OR course_name = 'Chinese' but in this result I can get User2 record which is not my expected result. I want the record only display the User take the course English+Chinese only.

• Copy 2 databases without detach in SQL 2005

  - by molgan

  Hello I have a server with live databases, and I have a test-server where I sometimes restore databases from the live one, to get fresh data. But this way I have to set up all the users again, I have about 4 different users with different permissions that need set again. Is there some way to do this a better way without using detach and attach, since I cant take the databases offline on the live-server? Prefered some thing I could run that "re-fills" the tables with fresh data. No need to redo stored procedures and rights. /M

• Simulating an identity column within an insert trigger

  - by William Jens

  I have a table for logging that needs a log ID but I can't use an identity column because the log ID is part of a combo key. create table StuffLogs { StuffID int LogID int Note varchar(255) } There is a combo key for StuffID & LogID. I want to build an insert trigger that computes the next LogID when inserting log records. I can do it for one record at a time (see below to see how LogID is computed), but that's not really effective, and I'm hoping there's a way to do this without cursors. select @NextLogID = isnull(max(LogID),0)+1 from StuffLogs where StuffID = (select StuffID from inserted) The net result should allow me to insert any number of records into StuffLogs with the LogID column auto computed. StuffID LogID Note 123 1 foo 123 2 bar 456 1 boo 789 1 hoo Inserting another record using StuffID: 123, Note: bop will result in the following record: StuffID LogID Note 123 3 bop

• Wrong SQLServer syntax: need help!

  - by user512602

  Hi, this is what I want to achieve: 4 tables are involved: Players with PlayerID as PK, Competitions with CompetID as PK Results with ResultID as PK and CompetID as FK And the 4th table: PlayerResultts with ResultID + PlayerID as PK and CompetID as new column I created. Competitions, results and PlayerResults are already populated and quite large (300000 PlayerResults so far). In order to populate the PlayerResults.CompetID column, I try a Update ... (Select....) request but I'm not aware of the right syntax and it fails. Here is my feeble attempt: update PlayerResults set competid = (select distinct(r.competid) from results r, playerresults p where r.resultID = p.resultid) Error is (of course): "Msg 512, Level 16, State 1, Line 1 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , , = or when the subquery is used as an expression." Can someone put me in the right direction? TIA

  Say I have the simple table below: KeyWordID KeyWord ----------- ---------- 1 Blue 3 Yellow 1 Yellow How would I select the KeyWordID that selects the KeyWordIDs that where both KeyWord is Blue and Yellow.
