pg_execute
(PHP 5 >= 5.1.0)
pg_execute — Sends a request to execute a prepared statement with given parameters, and waits for the result.
Description
resource pg_execute
( resource $connection
, string $stmtname
, array $params
)
resource pg_execute
( string $stmtname
, array $params
)
pg_execute() is like pg_query_params(),
but the command to be executed is
specified by naming a previously-prepared statement, instead of giving a
query string. This feature allows commands that will be used repeatedly to
be parsed and planned just once, rather than each time they are executed.
The statement must have been prepared previously in the current session.
pg_execute() is supported only against PostgreSQL 7.4 or
higher connections; it will fail when using earlier versions.
The parameters are identical to pg_query_params(), except that the name of a
prepared statement is given instead of a query string.
Parameters
-
connection
-
PostgreSQL database connection resource. When
connection
is not present, the default connection
is used. The default connection is the last connection made by
pg_connect() or pg_pconnect().
-
stmtname
-
The name of the prepared statement to execute. if
"" is specified, then the unnamed statement is executed. The name must have
been previously prepared using pg_prepare(),
pg_send_prepare() or a PREPARE SQL
command.
-
params
-
An array of parameter values to substitute for the $1, $2, etc. placeholders
in the original prepared query string. The number of elements in the array
must match the number of placeholders.
Warning
Elements are converted to strings by calling this function.
Return Values
A query result resource on success, or FALSE on failure.
