Syntax error converting datetime from character string.

    #116585

    I have a stored proc where in i have the following line of code

    SET @dtStopTime = cast(CONVERT(varchar(10),GETDATE(),110) + ' 23:59:59.000' as datetime)

    This proc works fine when runs from Query analyzer and also works fine when runs as part of job on a scheduled time.

    But This code is failing and returning the error (subject line) when This procedure was invoked when SQL Server is restarted. ( I have checked the checkbox "execute whenever SQL Server starts"on the procedure, its available as the proc is from master db).

    My procedure is lying in Master DB and i want this proc to be executed whenever SQL Server Started. also this proc is scheduled to run every day midnight. So, This procedure should run every day midnight as per schedule(This is working fine) and also this proc should run when SQL Server Starts ( this is failing).

    Any help would be highly appreciated.

    This SP will invoke at midnight to start capturing traces and willl stop at 11:59:59:00 PM on the same day to generate trace file of all the events captured that day.

    SELECT @dtStoptime = CONVERT(DATETIME,CONVERT(VARCHAR(11),GETDATE(),120)+ '23:59:59.999',120)

    Or try this so you are not convert between varchar and datetime at all.

    SET @dtStopTime = dateadd(s,-1,dateadd(d,datediff(d,0,GETDATE()) + 1,0))

     

    Not sure why it would be an issue thou. Might dig later.

    David's solution is almost correct, but not quite... the resolution for DATETIME datatypes is 3 milliseconds... David's solution rounds up to midnight... you need to do this instead...

    SELECT @dtStoptime = CONVERT(DATETIME,CONVERT(VARCHAR(11),GETDATE(),120)+ '23:59:59.997',120)

    Really, it would be better if your code did round up to midnight and then use < instead of <= in any of your enddate comparisons.
