    +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.
