pg_send_execute
Sends a request to execute a prepared statement with given parameters, without waiting for the result(s)
Description
intbool pg_send_execute(PgSql\Connection $connection, string $statement_name, array $params)
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
-
An PgSql\Connection instance.
-
statement_name
-
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 or 0 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);
}
?>
