  • Great script. Thanks a million.

  • i've change it a bit , so the curent size on the db to be more acurate ... se tempdb...

    thanks 🙂

  • Even better. Thanks.

  • i get an error with this script:

    Column name or number of supplied values does not match table definition.

  • I do not get the error. Could you re-post the exact syntax you are trying to run? Also, could you send version of the db server?

  • I use the exact same script as you have posted. I tried to find the exact line that cause the error. It's this one:

    delete t from @tmpdb t where DBName = @DBName and [FileName] = @FileName

    if i replace the last condition with an empty string, it work (it will loop forever but the error is gone)

    delete t from @tmpdb t where DBName = @DBName and [FileName] = ''

    it seems that the @FileName variable is the problem but i can't find why

    I'm using SQL Server 2012

  • I doubt that is the problem. Are you referring to my original script or the re-write posted in forum? The re-write posted in the forum is different than my script. If you notice that the table variable @tmpspace has different columns than the one in my original script. I'm willing to guess that would be the cause of the problem. Run the original script below and let me know if this works.

  • the one i used is the one on this forum. The last one you've just posted have the error too. The same line. And if i remove the @FileName condition, the script run.

    very weird!

  • i believe you hve your data file on the c: drive in 'program files' or other dir with spaces in it... or the name itself... you must enclose the filname in the brackets tooo as for dbnamw...

  • ok... i have configured the debugger and found something new. The real line that is causing the error is this one on the second pass in the 'while loop':

    insert into @vlf

    exec(@query)

    in the @query variable, i have this:

    use [Corporatif]

    DBCC loginfo

    and the result of this query is this:

  • double post.. sorry!

  • ok... i now see the problem. The DBCC loginfo is returning one addition column that the script doesnt know about. It's the column RecoveryUnitId. This is why i have the error.

    The correction is just to add the RecoveryUnitId field to the @vlf table:

    declare @vlf table

    (RecoveryUnitId int,

    FileID int,

    FileSize bigint,

    StartOffset bigint,

    FSeqNo int,

    [Status] int,

    Parity int,

    CreateLSN numeric(25,0))
