Hi,
I suggest the following:
- If a literal is always going to be the same value than it is marginal whether you use a bind variable for this.
- I'm not sure why you are using the to_char to_date functions? You should be able to create a bind variable of type date - hence you shouldn't need to worry about the format.
Cheers,
Craig.

Subject: Stupid Bind Variable question
In any given SQL statement, do I need (or should I :^) ) create a bind variable for every literal value even if it is one of the following cases:
1) substring in a substr function
2) date/time format mask used in to_char or to_date function
3) comparison value in a decode/case statement (not in the where clause)
I've seen it mentioned to use bind variables when comparing a column to a literal in the where clause, but nothing specific about the above scenarios. Basically what I am asking is, do all literals need to be made bind variables?
Thanks.
