The query below lists table check constraints.
Query
select schema_name(t.schema_id) + '.' + t.[name] as [table],
col.column_id,
col.[name] as column_name,
con.[definition],
case when con.is_disabled = 0
then 'Active'
else 'Disabled'
end as [status],
con.[name] as constraint_name
from sys.check_constraints as con
left outer join sys.objects as t
on con.parent_object_id = t.object_id
left outer join sys.all_columns as col
on con.parent_column_id = col.column_id
and con.parent_object_id = col.object_id
order by schema_name(t.schema_id) + '.' + t.[name],
col.column_id
Columns
- table - schema and table name
- column_id - column table id (unique within table)
- column_name - name of the column for column-level check constraints, null for table-level check constraints
- definition - SQL expression that defines this check constraint
- status - constraint status:
- 'Active' if constraint is active,
- 'Disabled' for disabled constraints
- constraint_name - name of the constraint in the database
Rows
- One row: represents one check constraint
- Scope of rows: the query returns all check constraints in the database
- Ordered by: table schema and name, table column id
