# sys.system_sql_modules (Transact-SQL)
[!INCLUDE [sql-asdb-asdbmi-asa-pdw](../../includes/applies-to-version/sql-asdb-asdbmi-asa-pdw.md)]

  Returns one row per system object that contains an SQL language-defined module. System objects of type FN, IF, P, PC, TF, V have an associated SQL module. To identify the containing object, you can join this view to [sys.system_objects](../../relational-databases/system-catalog-views/sys-system-objects-transact-sql.md).

|**definition**|**nvarchar(max)**|SQL text that defines this module.|
