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. --- End diff -- Global: change "an SQL" to "a SQL" (pronounced 'sequel') > document the HAWQ built-in languages (SQL, C, internal) > ------------------------------------------------------- > > Key: HAWQ-1096 > URL: https://issues.apache.org/jira/browse/HAWQ-1096 > Project: Apache HAWQ > Issue Type: Improvement > Components: Documentation > Reporter: Lisa Owen > Assignee: David Yozie > Priority: Minor > > the HAWQ docs do not discuss the built-in languages supported by HAWQ - SQL, > C and internal. add content to introduce these languages with relevant > examples and links. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
