Hi Mike,
Okay – opening an incident will be great as my team will handle this. If we could get the sample code – include ASE version, table DDL, that sort of thing plus error messages.
We made some changes after SP122 but not sure they will affect this one. Plus, if the two signatures are different than a sample to demonstrate the difference, based on your developers' experience will be extremely helpful.
If they have the opportunity to test current 15.7 SP130 release that would be helpful as well.
Cheers,
-Paul
