LOCK TABLES
The following command is not supported in MemSQL.
LOCK TABLES table_name [ READ | WRITE ] [, table_name [READ | WRITE]] ...
By default, it will emit this warning:
Feature 'LOCK TABLES' is not supported by MemSQL. Execution will continue, but the feature will be ignored.
The command has no effect.
If you set the global system variable warn_level to errors, then this command will return an error instead.
The default behavior of returning a warning is for increased compatibility with some MySQL-compatible tools.
