fbsql_errno Returns the error number from previous operation php函数


fbsql_errno

(PHP 4 >= 4.0.6, PHP 5)

fbsql_errnoReturns the error number from previous operation

说明

int fbsql_errno ([ resource $link_identifier ] )

Returns the numerical value of the error message from previous FrontBase operation.

Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno() to retrieve the error code. Note that this function only returns the error code from the most recently executed fbsql function (not including fbsql_error() and fbsql_errno()), so if you want to use it, make sure you check the value before calling another fbsql function.

参数

link_identifier

fbsql_connect()fbsql_pconnect() 返回的 FrontBase 链接标识符.

如可选并未指定,函数会尝试查找一个到 FrontBase 服务器的开放链接,且如没有找到这样的链接,会尝试通过不带参数调用 fbsql_connect() 来创建一个。

返回值

Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.

范例

Example #1 fbsql_errno() Example

<?php
fbsql_connect
("marliesle");
echo 
fbsql_errno() . ": " fbsql_error() . "<br />";
fbsql_select_db("nonexistentdb");
echo 
fbsql_errno() . ": " fbsql_error() . "<br />";
$conn fbsql_query("SELECT * FROM nonexistenttable;");
echo 
fbsql_errno() . ": " fbsql_error() . "<br />";
?>
