◆ apply_type_flags()

◆ has_constraint_enforcement()

virtual bool PT_column_attr_base::has_constraint_enforcement ( ) const
inlinevirtual

Check for the [NOT] ENFORCED characteristic.

Returns
true if the [NOT] ENFORCED follows the CHECK(...) clause, false otherwise.

Reimplemented in PT_constraint_enforcement_attr.

◆ is_constraint_enforced()

virtual bool PT_column_attr_base::is_constraint_enforced ( ) const
inlinevirtual

Check if constraint is enforced.

Method must be called only when has_constraint_enforcement() is true (i.e when [NOT] ENFORCED follows the CHECK(...) clause).

Returns
true if constraint is enforced. false otherwise.

Reimplemented in PT_constraint_enforcement_attr.

◆ set_constraint_enforcement()

virtual bool PT_column_attr_base::set_constraint_enforcement ( bool  enforced)
inlinevirtual

Update the ENFORCED/NOT ENFORCED state of the CHECK constraint.

Parameters
enforcedtrue if ENFORCED, false if NOT ENFORCED.
Returns
false if success, true if error (e.g. if [NOT] ENFORCED follows something other than the CHECK clause.)

Reimplemented in PT_check_constraint_column_attr.
