EXECUTE(7)


NAME

   EXECUTE - execute a prepared statement

SYNOPSIS

   EXECUTE name [ ( parameter [, ...] ) ]

DESCRIPTION

   EXECUTE is used to execute a previously prepared statement. Since
   prepared statements only exist for the duration of a session, the
   prepared statement must have been created by a PREPARE statement
   executed earlier in the current session.

   If the PREPARE statement that created the statement specified some
   parameters, a compatible set of parameters must be passed to the
   EXECUTE statement, or else an error is raised. Note that (unlike
   functions) prepared statements are not overloaded based on the type or
   number of their parameters; the name of a prepared statement must be
   unique within a database session.

   For more information on the creation and usage of prepared statements,
   see PREPARE(7).

PARAMETERS

   name
       The name of the prepared statement to execute.

   parameter
       The actual value of a parameter to the prepared statement. This
       must be an expression yielding a value that is compatible with the
       data type of this parameter, as was determined when the prepared
       statement was created.

OUTPUTS

   The command tag returned by EXECUTE is that of the prepared statement,
   and not EXECUTE.

EXAMPLES

   Examples are given in the EXAMPLES section of the PREPARE(7)
   documentation.

COMPATIBILITY

   The SQL standard includes an EXECUTE statement, but it is only for use
   in embedded SQL. This version of the EXECUTE statement also uses a
   somewhat different syntax.
