From Linux Man Pages
EXECUTE - execute a prepared statement
EXECUTE plan_name [ (parameter [, ...] ) ]
Contents |
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 cur-
rent 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 state-
ments 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:prepare|prepare(7)]]].
PARAMETERS
plan_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 of
a type compatible with the data type specified for this parameter position in the PREPARE command that
created the prepared statement.
OUTPUTS
The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE.
EXAMPLES
Examples are given in the Examples [[[7:prepare|prepare(7)]]] section of the PREPARE [prepare(l)] documentation.
COMPATIBILITY
The SQL standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXE-
CUTE statement also uses a somewhat different syntax.
