Question

我正在尝试使用workbench 6.0 CE将MS SQL数据库迁移到MySQL。在“逆向工程选择方案”步骤中，我得到“UnicodeDecodeError”。我想知道如何调试这个问题？所有表格名称都很直接，不使用任何特殊字符。

错误日志如下：

我知道这是一个老问题，但是出于相同的原因，我的MySQL Workbench在尝试从SQL Server数据库迁移时崩溃了。我已经解决了将默认编码更改为“ C：\ Program Files \ MySQL \ MySQL Workbench 8.0 CE \ modules \ db_mssql_grt.py”文件中的相应编码的问题。我有这两行（我的脚本中为141-142）：


    con.add_output_converter(-150, lambda value: value if value is None else value.decode('utf-16'))
    con.add_output_converter(0, lambda value: value if value is None else value.decode('utf-16'))

在我的情况下，SQL Server使用的是cp1252，因此我将utf-16更改为cp1252。
