The wildcards are part of your input string, so you'd need
value = "%raj%" (looks like there was an extraneous single
quote in the original) and your sql would be
"SELECT * FROM tb_name WHERE firstname LIKE ?"
Named parameters are usually used for calling
stored procedures. As far as I know, you can't use them
with plain Sql.
