我收到此属性错误：＆＃39;没有类型＆＃39;目标没有属性＆＃39; split＆＃39;当我试图在mysql workbench中将sql db迁移到mysql db时

这些是日志详细信息：

Failed

我尝试了一个解决方案（如下所示，取自链接https://bugs.mysql.com/bug.php?id=66030&thanks=3&notify=195）。但它没有帮助。我仍然得到同样的错误。请帮我。

解决方案：

//我们需要您的帮助才能诊断出这一点。使用文本编辑器，打开/Applications/MySQLWorkbench.app/Contents/PlugIns/db_mssql_grt.py文件在第174行附近，您会找到一条如下所示的行： ver_string = execute_query（connection，＆＃34; SELECT SERVERPROPERTY（＆＃39; ProductVersion＆＃39;）＆＃34;）。fetchone（）[0]

将其更改为：

ver_string = execute_query(connection, "SELECT CAST(SERVERPROPERTY('ProductVersion') AS VARCHAR)").fetchone()[0]

然后保存并重试。谢谢！ //
