Try getting an oracle trace ( like 10046 ) and put it thru a resource profiler like tkprof etc.

What you have included does not look like a complete SQL statement ( missing some right parens ).

It is pretty standard using variables in a plsql environment at times. Can you define them ahead of time in C#?

This sql statement is just a piece of the whole statement. If I try to write out the form_slag just before statement dataadapter.fill(datatable) the compiler will complain about not knowing about the form_slag.
This form_slag is either defined before the sql statement is executed or defined in the database in some way.
I far as I understand it seems to me that this form_slag is not known before this dataadapter.fill(datatable)
so the definition must be within the database in some way.

Is it possible that the definition of this form_slag is in the database in some way.
The .NET seems to not knowing anything about this form_slag
