I am trying to use a substitution variable following the select statement. My need is to take from one to 30 requests from a website for redisplay.
I have tried this approach in a package...

Define v_web_in = 'Column1,Column2,Column3'

Cursor lc_need_rec IS
Select &&v_web_in
From mytable
Where condition='true'

where v_web_in is defined as the columns to be selected based upon checkbox choices from the web site.

Any suggestions out there ??

This sound like you will need dynamic SQL...

And depending on which version of Oracle you run, you have 2 different way of codig it. Starting Oracle 8i, you can use Native Dynamic SQL which is a lot easier that the old DBLS_SQL Package.

see for Native

See for DBMS_SQL
http://technet.oracle.com/doc/oracle8i_816/server.816/a76936/dbms_sql.htm#998100

Either way, that's the only way you are going to create a valid Sql Statement.

Good luck!
