MySQL转储.sql脚本并导入到Apache derby

[英]MySQL dump .sql script and import to an apache derby

原文 2010-09-20 12:21:50 1 2 mysql/ export/ derby/ ansi

So presumably mysqldump can export to ansi compatible format so that you can import to other vendors' databases. 因此，大概mysqldump可以导出为ansi兼容格式，以便您可以导入其他供应商的数据库。

However trying to import to an apache derby I face all this syntax errors. 但是，尝试导入到Apache德比中时，我遇到了所有这些语法错误。 Thought I try some regex and fix things but it seems that there are more than a couple. 以为我尝试了一些正则表达式并修复了问题，但似乎还有很多。

Is there something I'm missing about mysqldump? 关于mysqldump我缺少什么吗？ Tried ddlutils but couldn't make progress after step 3 with these docs which seem out of date. 尝试了ddlutils，但在第3步之后无法使用这些似乎过时的文档取得进展。

Do I have any other options with that? 我还有其他选择吗？

The mysqldump option --compatible=ansi doesn't produce a SQL script that is fully ANSI compatible, it just tries to produce a result that is more ANSI compatible: "Produce output that is more compatible with other database systems or with older MySQL servers." mysqldump选项--compatible=ansi不会生成与ANSI 完全兼容的SQL脚本，它只会尝试生成与ANSI 更加兼容的结果：“生成与其他数据库系统或旧版MySQL服务器更兼容的输出”。

Unfortunately, the SQL syntax supported by each database is a bit different. 不幸的是，每个数据库支持的SQL语法都有些不同。 SQL is a relatively weak standard, much weaker than Javascript or even C. Some databases support compatibility features like MySQL does, or even compatibility modes (disclaimer: I'm the main author of H2), but even this is not enough sometimes. SQL是一个相对较弱的标准，比Java甚至C语言都弱得多。某些数据库支持MySQL等兼容功能，甚至支持兼容模式（免责声明：我是H2的主要作者），但是有时这还不够。

You have multiple options: you could change the generated SQL script by hand, or you could use another tool to copy the table structure / data. 您有多种选择：可以手动更改生成的SQL脚本，也可以使用其他工具复制表结构/数据。 One such tool is the SQuirreL DB Copy Plugin (I have never actually used it, but from what I heard it works well). 这样的工具之一就是SQuirreL DB Copy插件（我从未真正使用过它，但是据我所知它运行良好）。
