How to retrieve fixed length character data (for example char(5) ) from database using hibernate SQLQuery?

example:

Object obj=session.createSQLQuery("select col1 from table1 where
col2='12345'").uniqueObject();

Note: datatype of column 'col1' is char(5)

In result iam getting only the first character, the rest of the characters are gone.......need help in retrieving the whole data

please let me know if i did any mistake in the coding..........also let me know if it is possible or not
thanks
