[ @objname = ] 'object'

Is the qualified or unqualified name of a stored procedure, trigger, table, or view in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure or trigger, the stored procedure or trigger will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures that reference the table or view will be recompiled the next time they are run.

0 (success) or a nonzero number (failure)

sp_recompile looks for an object in the current database only.

The queries used by stored procedures and triggers are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures and triggers may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

Note:
SQL Server automatically recompiles stored procedures and triggers when it is advantageous to do this.

Requires ALTER permission on the specified object.

The following example causes stored procedures that act on the Customer table to be recompiled the next time they are run.

USE AdventureWorks;
GO
EXEC sp_recompile N'Sales.Customer';
GO
