How to make the resultset returned from oracle keeps its column aliases characters case

问题

I am trying to querying some sql statment againest oracle database.

I am using Java ResultSetMetaData to get column alias names (through: rsmd.getColumnLable() )

The query looks like:

select part_id partId, part_num partNumber from tbl;

But the result set meta-data returns for me the aliases as partid and partnumber respectively ...

But I need to get the aliases in the same characters case the user choose, so I need to get it as partId and partNumber respectively.

How to accomplish that?

Thanks.

回答1:

Column names and aliases are case insensitive by default, if you want to preserve case in an oracle statement you could quote the names like this:

select part_id "partId", part_num "partNumber" from tbl;

In my tests the column names where returned in uppercase when not using the quotes, so the behaviour might also depend on the version of the jdbc driver.
