You use Microsoft SQL Server Profile to evaluate a query named Query1. The Profiler report indicates the following issues:
At each level of the query plan, a low total number of rows are processed.
The query uses many operations. This results in a high overall cost for the query.
You need to identify the information that will be useful for the optimizer.
What should you do?
A. Start a SQL Server Profiler trace for the event class Performance statistics in the Performance event category.
B. Create one Extended Events session with the sqlserver.missing_column_statistics event added.
C. Start a SQL Server Profiler trace for the event class Soft Warnings in the Errors and Warnings event category.
D. Create one Extended Events session with the sqlserver.error_reported event added.
