  • RE: Can a long running select query cause locking and impact an update transaction?

    Yes it can. As that piece from books online stated, a select takes shared locks for the duration of it's execution. A shared lock means that while other reads can...

  • RE: 70-431

    Thanks Todd. I noticed the E-Learning. How long does it take? I was considering taking it during lunch breaks next week.

    I've got a lot of experience with 2000, and have...

  • RE: Cursor or not

    There's not that much difference between a cursor that processes a set of records one by one and a while loop that processes a set of records one by one....

  • RE: Is it possible to trap or log FATAL ERROR from a stored proc?

    Can you give an example of @sql_string?

    There is an error avoidence technique that you could use:

    IF EXISTS (SELECT 1 FROM sysobjects WHERE name='TableToBeDropped')

     DROP TABLE TableToBeDropped

  • RE: Help with Left Join in query and ordering

    Yes, but it will require a subquery to do the calculation

    SELECT PRODUCTS.PRODUCT_ID, PRODUCTS.P_NAME, VOTES.V_SCORE

    FROM [PRODUCTS]

    LEFT JOIN [VOTES]

      ON VOTES.PRODUCT_ID = PRODUCTS.PRODUCT_ID AND

           VOTES.USER_ID = 3

    LEFT OUTER JOIN (SELECT Product_ID,...

  • RE: Correlate dbname and his dbfile (data+log)

    I'm not a fan of dynamic SQL, but this is a place where it will help.

    DECLARE @DBName varchar(20)

    SET @DBName = 'msdb'

    DECLARE @sSQL VARCHAR(500)

    SET @sSQL = 'SELECT name, filename FROM '...

  • RE: Writing queries best practice

    I mostly agree with Marco. Here's a suggested rewrite

    SELECT Table01.field01, Table01.field02, Table01.field03, Table01.field04, Table01.field05

     FROM Table01 LEFT OUTER JOIN Table02 ON Table01.field03 = Table02.field03

     LEFT OUTER JOIN Table03 ON Table01.field03 = Table03.field03

     WHERE...

  • RE: Changing collation.

    You can change TempDB's collation by changing the colation of then entire server. That will involve rebuilding the master database with the new collation. Look up Rebuildm in books online.

  • RE: Updates which don''''t participate in a transaction.

    How about building up an insert/update statement as a string then executing it after the rollback. Something like this

    BEGIN TRANSACTION

    Insert into VeryImportantTable (...) values (...)

    IF @@Error!=0

    BEGIN

    DECLARE @sSQL VARCHAR(1000)

    SET @sSQL =...

  • RE: Is it possible to trap or log FATAL ERROR from a stored proc?

    Yes you can. You can't trap the ones above 20, but those are written into the error log. 11 through 19 are standard errors, less than 11 are warnings or...

  • RE: Is it possible to trap or log FATAL ERROR from a stored proc?

    Correction. TRY...CATCH only catch errors with severity>10 (anything less than that is a warning or information message and not an error) and will only catch errors that don't close the...

  • RE: Using MIN/MAX in update

    Ah, then you should be able to get what you want in Table3 with a single insert, no need for a seperate update after.

    INSERT INTO Table3(custID, DOB_Min, DOB_Max)

    SELECT Table1.CustID, MIN(Table2.DOB),...

  • RE: Using MIN/MAX in update

    You can do it in one step(if you had custID in table 2 that is)

    Insert into Table3 (CustID, DOB_Min, DOB_Max)

    SELECT CustID, MIN(C_DOB), MAX(C_DOB) FROM Table2 GROUP BY CustID

    How do table1...

  • RE: READTEXT into variable

    <sarcasm>Well excuse me for trying to help</sarcasm>

    Just offerng an additional possibility that doesn't require adding an additional parameter to the procedure to deal with the output of substring.

  • RE: READTEXT into variable

    Declare the variable as varchar.

    DECLARE @v-2 VARCHAR(8000)

    SELECT @v-2 = SUBSTRING(Code,@StartPos, @Length) FROM tmp_AuditTriggerCustomised

    You'll get an error if you give a length over 8000 (since the variable can't hold more than 8000 characters)

    The...
