       EXECUTE - execute a prepared statement

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

       EXECUTE  is used to execute a previously prepared statement. Since prepared statements only exist for the dura-
       tion 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 [prepare(7)].

       name   The name of the prepared statement to execute.

              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.

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

       Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation.

       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.
