php - PHP 中的 ORA-12504 警告

Question

我有以下脚本用于在 Linux 中使用 PHP 检查 Oracle 数据库连接:

<?php
        $conn = oci_connect('proekt', 'proekt1', 'localhost:1521');

        $stid = oci_parse($conn, "select 1+2 as sum from dual");
        oci_execute($stid);
        $row = oci_fetch_array($stid, OCI_BOTH);
        echo $row[SUM];
?>

但它给了我这个警告:

Warning: oci_connect(): ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA in /var/www/test.php on line 2

我该如何解决它，问题是什么？

Answer 1

更改 oci_connect() 中的第三个参数帮助了我:

$conn = oci_connect('proekt', 'proekt1', ' (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = proekt)
    )
  )');
