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.
Returns TRUE
on success, FALSE
on failure. Use pg_get_result() to determine the query result.
<?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); } ?>
