Dinesh,

I think what you are showing here IS the way to build up a dynamic sql=20=

statement.  I'm not sure that you can write a prepared statement within=20=

the body of a function, which would then look more like what you are=20
suggesting you want to do--perhaps others on the list can enlighten us=20=

about that.  In any case, why won't using the || operator work for you?
