Creating a SQL Insights Task

Scenarios

SQL Insights allows you to not only query all executed SQL statements, but also analyze and search for the tables that are accessed and updated most frequently, and the SQL statements that have the longest lock wait, helping you quickly identify exceptions.

Constraints

• You need to enable Collect All SQL Statements before using SQL Insights.
• After Collect All SQL Statements is disabled, new SQL statements will not be collected anymore and the collected SQL data will be deleted.
• Only the tasks created in the last two days can be displayed.
