MySQL dump .sql script and import to an apache derby

Question

So presumably mysqldump can export to ansi compatible format so that you can import to other vendors' databases.

However trying to import to an apache derby I face all this syntax errors. Thought I try some regex and fix things but it seems that there are more than a couple.

Is there something I'm missing about mysqldump? Tried ddlutils but couldn't make progress after step 3 with these docs which seem out of date.

Do I have any other options with that?

Answer 1

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."

Unfortunately, the SQL syntax supported by each database is a bit different. 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.

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. One such tool is the SQuirreL DB Copy Plugin (I have never actually used it, but from what I heard it works well).

如果可以CSV格式或类似格式导出数据，则可以使用Derby数据导入过程来导入数据： http : //db.apache.org/derby/docs/10.7/ref/rrefimportproc.html
