dbx_error — Report the error message of the latest function call in the module

说明

dbx_error ( object $link_identifier ) : string

dbx_error() returns the last error message.

参数

link_identifier: The DBX link object returned by dbx_connect()

返回值

Returns a string containing the error message from the last function call of the abstracted module (e.g. mysql module). If there are multiple connections in the same module, just the last error is given. If there are connections on different modules, the latest error is returned for the module specified by the link_identifier parameter.

范例

Example #1 dbx_error() example

 <?php
$link   = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password")
    or die("Could not connect");

$result = dbx_query($link, "select id from non_existing_table");
if ($result == 0) {
    echo dbx_error($link);
}
dbx_close($link);
?>

注释

Note:

Always refer to the module-specific documentation as well.

The error message for Microsoft SQL Server is actually the result of the mssql_get_last_message() function.

The error message for Oracle (oci8) is not implemented yet.
