Hi @psilberk Thanks for the PR! We already have a PR addressing support for Oracle Dialect to ChatMemory #3601. Could you review the PR#3601 instead of having a duplicate one please?

Hi @ilayaperumalg , yes, sorry I didn't see that PR! It looks like several things need to be updated int this other PR, some minors (like the switch instead of multiple if else) and some more complex (tests). It also has an unnecessary index in the schema creation.

@psilberk No problem at all. thanks for your contribution! Could you add your review comments in #3601 and we can discuss the best way forward to get Oracle ChatMemory support added by co-ordinating this with @fanxt0218?

@psilberk Once you can confirm collaborating with the PR #3601, we can close this PR as duplicate. Thanks.
