java - 如何在 Jooq 中为例程添加 OrderBy？

Question

我正在使用下面的代码

Transaction transaction = Transaction.current();
        SelectQuery<Record> selectQuery = transaction.selectQuery();
        selectQuery.addSelect(Folder.FOLDER.FOLDER_RSN, Routines.fFoldernumber(Folder.FOLDER.FOLDER_RSN).as("FolderNumber"),
                Folder.FOLDER.FOLDER_NAME, Folder.FOLDER.FOLDER_TYPE);
selectQuery.addFrom(FolderPeople.FOLDER_PEOPLE);

现在我想在FolderNumber上添加OrderBy，如下所示

selectQuery.addOrderBy("FolderNumber")

在上述情况下如何添加OrderBy？

Answer 1

jOOQ生成的存储函数实现org.jooq.Field ，因此您只需将它们添加到 ORDER BY 子句中即可:

selectQuery.addOrderBy(fFoldernumber(...));

您可能还需要考虑创建存储函数调用的本地引用，而不是重复整个调用:

Field<?> folder = Routines.fFoldernumber(Folder.FOLDER.FOLDER_RSN).as("FolderNumber");
// ...
selectQuery.addSelect(..., folder);
selectQuery.addOrderBy(folder);
