B. to make sure a table has no structural problems
C. to find out why a query takes a long time to execute on a given table
D. to improve performance by updating index distributing statistics on InnoDB tables
E. to make sure that no table indexes are corrupted
Answer: B,E
Explanation
The CHECK TABLE statement performs an integrity check on table structure and contents. It works for
