Data Distribution & Estimated row countgreenspun.com : LUSENET : SQL Server Database Administration : One Thread |
Hi!Iīd like to make my questions more concrete. I want to access some statistical information used by query optimizer.
1. How can I access distribution statistics?
I canīt store the result of DBCC SHOW_STATISTICS since that command returns more than one result set.
2. How can I estimate the number of tuples that will be returned by query?
This information exist in query plan but I canīt access that value.
ps. I canīt believe that there is no easy way to access these values. So I donīt want to print the output of DBCC command/Execution plan to a text file and to process that file.
Cheers, FA.

Fuat,Distribution steps are only recorded for the first column. There is no more information to see.
Good Luck,
Eric
