EXECUTE(7) PostgreSQL 9.2.7 Documentation 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.
