# cubrid_errno

(PECL CUBRID >= 8.3.1)

cubrid_errno — Return the numerical value of the error message from previous CUBRID operation

### 说明

cubrid_errno ([ resource `$conn_identifier` ] ) : int

Returns the error number from the last CUBRID function.

The cubrid_errno() function is used to get the error code of the error that occurred during the API execution. Usually, it gets the error code when API returns false as its return value.

### 参数

`conn_identifier`

  The CUBRID connection identifier. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.

### 返回值

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

### 范例

Example #1 cubrid_errno() example

    <?php
    $con = cubrid_connect('localhost', 33000, 'demodb', 'dba', '');
    $req = cubrid_execute($con, "select id, name from person");
    if ($req) {
        while (list ($id, $name) = cubrid_fetch($req))
        echo $id, $name;
    } else {
        echo "Error Code: ", cubrid_errno($con);
        echo "Error Message: ", cubrid_error($con);
    }
    ?>

以上例程会输出：

    Error Code: -493 Error Message: Syntax: Unknown class "person". select id, [name] from person
