Hello,

When I execute the following query, the error Divide by zero error encountered. is generated :
SELECT Object_name(qt.objectid),
       qs.execution_count                                                 AS
       [Execution Count],
       qs.execution_count / Datediff(second, qs.creation_time, Getdate()) AS
       [Calls/Second],
       qs.total_worker_time / qs.execution_count                          AS
       [AvgWorkerTime],
       qs.total_worker_time                                               AS
       [TotalWorkerTime],
       qs.total_elapsed_time / qs.execution_count                         AS
       [AvgElapsedTime],
       qs.max_logical_reads,
       qs.max_logical_writes,
       qs.total_physical_reads,
       Datediff(minute, qs.creation_time, Getdate())                      AS
       [Age in Cache]
FROM   sys.dm_exec_query_stats AS qs
       CROSS apply sys.Dm_exec_sql_text(qs.[sql_handle]) AS qt
WHERE  qt.[dbid] = Db_id()
ORDER  BY qs.execution_count DESC
OPTION (recompile);

Why?

Thanks

Please check all divisions and make sure none of those columns or record set listed below can return NULL. Add ISNULL() around them or COALESCE()
...
 / Datediff(second, qs.creation_time, Getdate()) AS  [Calls/Second],
...
/ qs.execution_count                          AS ...
....
/ qs.execution_count                         AS [AvgElapsedTime],

>Why?
Because the denominator in a division operation is a zero.  Why else?

The usual T-SQL way of handling divide by zero errors goes like this..
CASE WHEN denominator = 0 THEN 0 ELSE numerator / denominator END as column_name

Open in new window

So take the above template and apply it to the three places you have division operators in your query.
