pg_send_execute

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

pg_send_execute — Sends a request to execute a prepared statement with given parameters, without waiting for the result(s)

说明

pg_send_execute(PgSql\Connection $connection, string $statement_name, array $params): int|bool

Sends 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.

参数

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.

返回值

Returns true on success, false or 0 on failure. Use pg_get_result() to determine the query result.

更新日志

版本	说明
8.1.0	现在 `connection` 参数接受 PgSql\Connection 实例，之前接受资源(resource)。

范例

示例 #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);
  }
  
?>
