RE: Different Plans for Literal Vs Bind Variables

What's the DB version?  If it's 9i+, are you using bind variable peeking?  If 
so, then the plan with the literal should be the same as the plan with the bind 
variable unless the bind statement is already cached with a plan optimized 
based on a significantly different bind value.  If you're not using bind 
variable peeking, the usual solution is to provide a hint or stored outline.  
If you can't do a hint since it's coming from PeopleSoft, then the outline is 
the way to go, or if you're in 10g and have the tuning pack, can use a SQL 
Profile, but if you're in 10g, then you should probably be using bind variable 
peeking.
