Question

when I have a query result for something like:

select col as newName from table;

and I then do (in java) :

rs.getMetaData().getColumnName(i)

it returns the name of the column instead of “newName”…

if however I do

select concat(col,'') as newName from table;

it returns the expected “newName”

is there a way to get the “newName” without messing with tho sql query?

This is all mysql, java, tomcat 6.

Answer 1

Try using getColumnLabel() instead:

rs.getMetaData().getColumnLabel(i);

FYI, I did a test and rs.getMetaData().getColumnName(i) worked for me – ie it gave me the alias, not the column name, but perhaps you are using an older version of the JDBC driver and/or mysql database.
