Re: Bind Sensitivity and PL/SQL cursor caching

Hi Patrick,

Session cached cursors are awesome and would be a shame to lose them. I know you've simplified your use case, but is it possible that you already know what the skewed inputs are at run time? If so, depending on the inputs you could call a different _hinted_ SQL to produce the plan you want. Then the rest could use a different plan.

No school like the old school.
