Detailed Description

Class to represent check constraint in the TABLE instance.

The Sql_table_check_constraint is a Sql_check_constraint_share with reference to the parent TABLE instance and itemized (materialized) form of check constraint expression. Sql_table_check_constraint is prepared from the Sql_check_constraint_share of TABLE_SHARE instance.
