pg_send_prepareSends a request to create a prepared statement with the given parameters, without waiting for completion


pg_send_prepare ( resource $connection , string $stmtname , string $query ) : bool

Sends a request to create a prepared statement with the given parameters, without waiting for completion.

This is an asynchronous version of pg_prepare(): it returns TRUE if it was able to dispatch the request, and FALSE if not. After a successful call, call pg_get_result() to determine whether the server successfully created the prepared statement. The function's parameters are handled identically to pg_prepare(). Like pg_prepare(), it will not work on pre-7.4 versions of PostgreSQL.



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().


The name to give the prepared statement. Must be unique per-connection. If "" is specified, then an unnamed statement is created, overwriting any previously defined unnamed statement.


The parameterized SQL statement. Must contain only a single statement. (multiple statements separated by semi-colons are not allowed.) If any parameters are used, they are referred to as $1, $2, etc.

Valores devueltos

Returns TRUE on success, FALSE on failure. Use pg_get_result() to determine the query result.


Ejemplo #1 Using pg_send_prepare()

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);
