# ingres_query

(PHP 4 >= 4.0.2, PHP 5)

ingres_query -- Send a SQL query to Ingres II

## Description

bool ingres_query ( string query [, resource link] )

警告
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

Returns `TRUE` on success, or `FALSE` on failure.

ingres_query() sends the given query to the Ingres server. This query must be a valid SQL query (see the Ingres SQL reference guide)

The query becomes part of the currently open transaction. If there is no open transaction, ingres_query() opens a new transaction. To close the transaction, you can either call ingres_commit() to commit the changes made to the database or ingres_rollback() to cancel these changes. When the script ends, any open transaction is rolled back (by calling ingres_rollback()). You can also use ingres_autocommit() before opening a new transaction to have every SQL query immediately committed.

Some types of SQL queries can't be sent with this function:

- close (see ingres_close())

- commit (see ingres_commit())

- connect (see ingres_connect())

- disconnect (see ingres_close())

- get dbevent

- prepare to commit

- rollback (see ingres_rollback())

- savepoint

- set autocommit (see ingres_autocommit())

- all cursor related queries are unsupported

例子 1. ingres_query() example

`<?php ingres_connect($database, $user, $password); ingres_query("select * from table"); while ($row = ingres_fetch_row()) { echo $row[1]; echo $row[2]; } ?>`

See also ingres_fetch_array(), ingres_fetch_object(), ingres_fetch_row(), ingres_commit(), ingres_rollback(), and ingres_autocommit().
