◆ add_check_constraints()

bool PT_check_constraint_column_attr::add_check_constraints ( Sql_check_constraint_spec_list check_const_list)
inlineoverridevirtual

Reimplemented from PT_column_attr_base.

◆ apply_alter_info_flags()

void PT_check_constraint_column_attr::apply_alter_info_flags ( ulonglong flags) const
inlineoverridevirtual

Reimplemented from PT_column_attr_base.

◆ contextualize()

bool PT_check_constraint_column_attr::contextualize ( Column_parse_context pc)
inlineoverridevirtual

Do all context-sensitive things and mark the node as contextualized.

Parameters
pccurrent parse context
Return values
falsesuccess
truesyntax/OOM/etc error

Reimplemented from Parse_tree_node_tmpl< Column_parse_context >.

◆ set_constraint_enforcement()

bool PT_check_constraint_column_attr::set_constraint_enforcement ( bool  enforced)
inlineoverridevirtual

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 from PT_column_attr_base.
