python - 数据库从Sybase迁移到MySQL : "error calling Python module function DbSQLAnywhereRE.reverseEngineer"

Question

我正在尝试从 Sybase 迁移数据库至 MySQL与 MySQL Workbench迁移工具。

我在连接数据源和目标数据库时没有问题，但是当它开始迁移时，我从日志消息中得到以下问题。

我该如何解决这个问题？

Answer 1

那是因为SQL要获取表名。查看db_sqlanywhere_re_grt.py:142，有:

SELECT st.table_name
FROM SYSTAB st LEFT JOIN SYSUSER su ON st.creator=su.user_id
WHERE su.user_name = '%s' AND st.table_type = 1

这是 sql anywhere 版本 < 10 的有效 sql，我猜你有最新版本。因此，您可以使用兼容的 SQL 编辑和更新该文件。 请记住，该文件中还有更多的 SQL 需要更新。 同时，请在 bugs.mysql.com 填写错误报告.
