我有一个从SQL Server到mySQL数据库的链接服务器(使用MySQL ODBC Driver 5.3的Windows Server).我有一个独特的情况,如果我在OPEN QUERY中转换它们,我只能返回我的longtext列:

SELECT * 
FROM
OPENQUERY (woocommerce, 'SELECT meta_id, CONVERT(meta_value using UTF8) as meta_value
                         FROM woocommerce.wp_postmeta WHERE meta_id = 9465078') 

如果我不转换/转换它我从链接服务器收到以下错误:

Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "woocommerce" reported an error. The provider reported an unexpected catastrophic failure.

我需要更新这个longtext列,"meta_value",但我不能,因为它已被转换/转换.

    UPDATE 
    OPENQUERY (woocommerce, 'SELECT meta_id, CONVERT(meta_value using utf8) 
                             FROM woocommerce.wp_postmeta WHERE meta_id = 9465078') 
    SET meta_value = 'outofstock';

有没有办法使用OPENQUERY和链接服务器更新已转换/转换列？我尝试过转换或转换它的方式.
