A procedure is a database object similar to a function. The difference is
that a procedure does not return a value, so there is no return type
declaration. While a function is called as part of a query or DML
- command, a procedure is called explicitly using
- the <xref linkend="sql-call"/> statement.
+ command, a procedure is called in isolation using
+ the <xref linkend="sql-call"/> command. If the CALL command is not
+ part of an explicit transaction, a procedure in many server-side
+ languages can commit, rollback, and begin new transactions during
+ its execution, which is not possible in functions.
