    [ @query_id = ] query_id , 
    [ @plan_id = ] plan_id, 
    [ @force_plan_scope = ] replica_group_id [;]

Arguments

[ @query_id = ] query_id

Is the query_id of the query. query_id is a bigint, with no default.

[ @plan_id = ] plan_id

Is the plan_id of the query plan that will no longer be enforced. plan_id is a bigint, with no default.

[ @force_plan_scope = ] replica_group_id

You can force and unforce plans on a secondary replica when Query Store for secondary replicas is enabled. Execute sp_query_store_force_plan and sp_query_store_unforce_plan on the secondary replica. The optional force_plan_scope argument defaults only to the local replica, but you can optionally specify a replica_group_id referencing sys.query_store_plan_forcing_locations.

Return Code Values

0 (success) or 1 (failure)

Remarks

Permissions

Requires the ALTER permission on the database.

Examples

The following example returns information about the queries in the query store.

SELECT Txt.query_text_id, Txt.query_sql_text, Pl.plan_id, Qry.*
FROM sys.query_store_plan AS Pl
JOIN sys.query_store_query AS Qry
    ON Pl.query_id = Qry.query_id
JOIN sys.query_store_query_text AS Txt
    ON Qry.query_text_id = Txt.query_text_id ;

After you identify the query_id and plan_id that you want to unforce, use the following example to unforce the plan.

EXEC sp_query_store_unforce_plan 3, 3;
