  • fbsql_error()

    (PHP 4 >= 4.0.6, PHP 5, PHP 7)

    Returns the error message from previous operation

    说明

    fbsql_error([resource $link_identifier]): string

    Returns the error message from previous FrontBase operation.

    Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_error() to retrieve the error text. 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

    由fbsql_connect()或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 text from the last fbsql function, or''(the empty string)if no error occurred.

    范例

    Example #1 fbsql_error() 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 />";
    ?>
