Subj:   Re: Query Execute time
From:   Prescott, Kyle R

From DBQLogTbl you can use the following timestamp calculations that will give you an interval data type - hours:minutes:seconds.n(6):

First step time minus query start time = parse/optimize phase

First response time minus first step time = execute time

First response time minus start time = total time or wall time

     ,firststeptime - starttime hour(4) to second as ParseOptimizeTime
     ,firstresptime - firststeptime hour(4) to second as QueryExecTime
     ,firstresptime - starttime hour(4) to second as WallTime
