有人能帮我解决这个问题吗

谢谢

您需要使用文本编辑器从您的站点尝试一些诊断

1）打开 C:\Program Files\MySQL\MySQL Workbench 6.2 CE\modules\db\u mssql\u grt.py文件，带记事本或记事本+，并在第174行附近您会发现一行如下所示：

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

2） 改为：

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

然后保存并重试。谢谢
