One can create table with the same name for `field` and `table` `check` constraint. For example: `create table t(a int check(a>0), constraint a check(a>10));` But when inserting new rows same error is always raised. For example with ```insert into t values (-1);``` and ```insert into t values (10);``` same error `ER_CONSTRAINT_FAILED` is obtained and it is not clear which constraint is violated. This patch solve this error so that in case if field constraint is violated the first parameter in the error message is `table.field_name` and if table constraint is violated the first parameter in error message is `constraint_name`.
