Implementing  Resultset   with  Pagination in a Web Application
But my Problem is thar the user can to choice 3 columns diferents for to order and Asc ou Desc
The Problem is thar the query is very large.
Example The user Choice column 1 ASC or Column2 DESC or COLUMN8 Desc
In other topic, tell me put as:
   ORDER BY decode(P_order,0, decode(P_coluna,1,LAST_NAME,2,CODE_NAME,3,VALUE)) ASC,
decode(P_order,1,decode(P_coluna,1,LAST_NAME,2,CODE_NAME,3,VALUE))  DESCBut did not work, work only when P_coluna =1 , for other number return me error
Put Query in Dynamic Query is Impossible is very great
Some have some idea?

Answer 1

I'm not sure why you think the size of the query
makes it more difficult to use dynamic SQL. From
your description of the problem, the only dynamic
piece is the ORDER BY clause. Everything other than
the ORDER BY clause is static.
Turning this into dynamic may take some effort, but
is far from impossible.Thank
Look length of my query ?
