Find constraint disabled in SQL Server
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I'm doing an audit of constraints in SQL Server.
How to find all constraints that are not enabled?
This, after using the next declaration:
alter table mytable nocheck constraint all
sql-server sql-server-2008 constraint alter-table ddl

Use the system views for this:
select * from sys.check_constraints
where is_disabled = 1;

Mike and Aaron are both on the right track - but the question asks for ALL constraints that are disabled - not just CHECK constraints (i.e., FKs can be disabled too).
Moreover, FKs can also be UNTRUSTED - which will yield the potential for not just bad/invalid DATA but can/will also lead to perf issues (as SQL Server can't/won't trust these FKs when creating execution plans) as per:
https://sqlserverfast.com/blog/hugo/2007/03/can-you-trust-your-constraints/
As such, I tend to use the following:
WITH constraints AS (
SELECT
QUOTENAME(SCHEMA_NAME(t.[schema_id])) + N'.' + QUOTENAME(t.[name]) [table] ,
c.[type_desc] [constraint_type],
c.[name] [constraint_name]
FROM
sys.tables AS t
INNER JOIN sys.check_constraints AS c ON t.[object_id] = c.parent_object_id
WHERE
c.is_disabled = 1
UNION
SELECT
QUOTENAME(SCHEMA_NAME([schema_id])) + N'.' + QUOTENAME(OBJECT_NAME([parent_object_id])) [table],
CASE WHEN is_disabled = 1 THEN 'FOREIGN_KEY (DISABLED)' ELSE 'FOREIGN_KEY (UNTRUSTED)' END [constraint_type],
[name] [constraint_name]
FROM
sys.[foreign_keys]
WHERE
[is_disabled] = 1 OR [is_not_trusted] = 1
)
SELECT
[table],
[constraint_type],
[constraint_name]
FROM
constraints
ORDER BY
[constraint_type], [table];

Mike and Aaron are both on the right track - but the question asks for ALL constraints that are disabled - not just CHECK constraints (i.e., FKs can be disabled too).
Moreover, FKs can also be UNTRUSTED - which will yield the potential for not just bad/invalid DATA but can/will also lead to perf issues (as SQL Server can't/won't trust these FKs when creating execution plans) as per:
https://sqlserverfast.com/blog/hugo/2007/03/can-you-trust-your-constraints/
As such, I tend to use the following:
WITH constraints AS (
SELECT
QUOTENAME(SCHEMA_NAME(t.[schema_id])) + N'.' + QUOTENAME(t.[name]) [table] ,
c.[type_desc] [constraint_type],
c.[name] [constraint_name]
FROM
sys.tables AS t
INNER JOIN sys.check_constraints AS c ON t.[object_id] = c.parent_object_id
WHERE
c.is_disabled = 1
UNION
SELECT
QUOTENAME(SCHEMA_NAME([schema_id])) + N'.' + QUOTENAME(OBJECT_NAME([parent_object_id])) [table],
CASE WHEN is_disabled = 1 THEN 'FOREIGN_KEY (DISABLED)' ELSE 'FOREIGN_KEY (UNTRUSTED)' END [constraint_type],
[name] [constraint_name]
FROM
sys.[foreign_keys]
WHERE
[is_disabled] = 1 OR [is_not_trusted] = 1
)
SELECT
[table],
[constraint_type],
[constraint_name]
FROM
constraints
ORDER BY
[constraint_type], [table];
