Subj:   Re: Missing lines in DBC.DBQLStepTbl
 
From:   DWellman

Hi,

How long between running your INSERT query and querying DBQLStepTbl ?

Rows are not written to the DBQLxxx tables immediately, they are held in a buffer and written at an interval and/or when the buffer is full. Diffferent DBQLxxx tables have different buffers an so may get written to disk at different times.

If I want to ensure that the DBQLxxx tables have the data I need then I usually issue an "END QUERY LOGGING" command first. This causes DBQLxxx buffers to be flushed.


Regards,

Dave
