+title: Using HAWQ Built-In Languages
+---
+
+This section provides an introduction to using the HAWQ built-in languages.
+
+HAWQ supports user-defined functions created with the SQL and C built-in
languages. HAWQ also supports user-defined aliases for internal functions.
+
+
+## <a id="enablebuiltin"></a>Enabling Built-in Language Support
+
+Support for SQL, internal, and C language user-defined functions is
enabled by default for all HAWQ databases.
+
+## <a id="builtinsql"></a>SQL
+
+SQL functions execute an arbitrary list of SQL statements. The SQL
statements in the body of an SQL function must be separated by semicolons. The
final statement in a non-void-returning SQL function must be a
[SELECT](../reference/sql/SELECT.html) that returns data of the type specified
by the function's return type. The function will return a single or set of rows
corresponding to this last SQL query.
