Enable defined limits on sqltrace

We would like to see the ability to add limits when enabling sqltrace to limit it to only trace by specific requirements. The basic one, which this alone would make a huge difference would be the ability to list one or more tables and only have it...

Sort data calculations should not be used to determine number of passes for UPDATE STATISTICS MEDIUM/HIGH statements where an index is used, fix misleading explain output

UPDATE STATISTICS MEDIUM/HIGH can be used with an explain option. The explain file always shows a sort data calculation which then determines the number of table scans (passes) the database engine will undertake. These are calculated before any de...
