Exception- The definition for user-defined data type ‘MyTypeList’ has changed.

The definition for user-defined data type ‘MyTypeList’ has changed. Exception when we rename or changed any User defined TYPE and it used in stored procedures.
Stored Procedures which is using this type variable will not run and throwing the exception. If we have large numbers of SP then it will to time consuming or irritating to re-compile all SP one by one.
Instead of using this manual process this script will help to fix all references.

DECLARE @Name NVARCHAR(776);

DECLARE REF_CURSOR CURSOR FOR
SELECT referencing_schema_name + '.' + referencing_entity_name
FROM sys.dm_sql_referencing_entities('dbo.MyTypeList', 'TYPE');

OPEN REF_CURSOR;

FETCH NEXT FROM REF_CURSOR INTO @Name;
WHILE (@@FETCH_STATUS = 0)
BEGIN
    EXEC sys.sp_refreshsqlmodule @name = @Name;
	PRINT @Name
    FETCH NEXT FROM REF_CURSOR INTO @Name;
END;

CLOSE REF_CURSOR;
DEALLOCATE REF_CURSOR;
