ingres_query — Send a SQL query to Ingres
ingres_query() sends the given query to the Ingres server.
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.
A valid SQL query (see the Ingres SQL reference guide).
Some types of SQL queries can't be sent with this function:
The connection link identifier. If not specified, the last opened link is used.
如果成功则返回 TRUE，失败则返回 FALSE。
Example #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];
}
?>
