JOOQ:使用字符串获取表和列? [英] JOOQ: Get table and columns with string?

问题描述

你好，我在Spring Boot中使用JOOQ，想知道是否有一种方法可以获取具有其名称字符串的表及其列?例如:

Hello I'm using JOOQ with Spring Boot and was wondering if there was a way to obtain a table and its columns with a string of their name? For example:

我希望能够通过执行以下操作来获取表格:

I want to be able to get a table by doing something like:

someObject.getTable("user")

然后使用该get方法的结果，我还想获取该表的所有列，并能够将列名与其他字符串进行比较.换句话说，如果有一种获取表的方法，我还可以从同一对象中获取表的列名吗?

Then using the result of that get method I also want to obtain all of that table's columns and be able to compare the column names to other strings. In other words if there is a way to get a table, can I also get the table's column names from that same object?

在此方面，我将不胜感激.

I would really appreciate any help with this.

推荐答案

是的，您可以:

当您生成模式时，所有这些信息都可以从生成的代码中获得.只需转到您的架构并查找表(区分大小写！):

When you generate your schema, all this information is available to you from generated code. Just go to your schema and look for the table (case-sensitive!):

Table<?> table = PUBLIC.getTable("user");

然后:

Field<?>[] fields = table.fields();

使用 org.jooq.Meta

如果尚未生成元数据，您仍然可以使用

Using org.jooq.Meta

If you don't have generated meta data, you can still look up things from your JDBC connection using DSLContext.meta(), from where you can navigate your schemas / tables / etc.
