Consider the CHECK TABLE command.
In which two situations should this command be used? (Choose two.)
A. to repair table structure problem
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
MyISAM and InnoDB tables. For MyISAM tables, it also updates the index statistics. If the table is a view, CHECK TABLE verifies the view definition. If the output from CHECK TABLE indicates that a table has problems, the table should be repaired.
