pg_send_execute
(PHP 5 >= 5.1.0, PHP 7)
pg_send_execute — Sends a request to execute a prepared statement with given parameters, without waiting for the result(s)
Description
$connection
, string $stmtname
, array $params
) : boolSends a request to execute a prepared statement with given parameters, without waiting for the result(s).
This is similar to pg_send_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. The function's parameters are handled identically to pg_execute(). Like pg_execute(), it will not work on pre-7.4 versions of PostgreSQL.
Parameters
-
connection -
PostgreSQL database connection resource. When
connectionis 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.
Return Values
Returns TRUE on success, FALSE on failure. Use pg_get_result()
to determine the query result.
Examples
Example #1 Using pg_send_execute()
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// Prepare a query for execution
if (!pg_connection_busy($dbconn)) {
pg_send_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
$res1 = pg_get_result($dbconn);
}
// Execute the prepared query. Note that it is not necessary to escape
// the string "Joe's Widgets" in any way
if (!pg_connection_busy($dbconn)) {
pg_send_execute($dbconn, "my_query", array("Joe's Widgets"));
$res2 = pg_get_result($dbconn);
}
// Execute the same prepared query, this time with a different parameter
if (!pg_connection_busy($dbconn)) {
pg_send_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
$res3 = pg_get_result($dbconn);
}
?>
