Toad for SQL server (trial) only undo some of the wrong queries

Hi,

I'm trying out Toad for SQL server 2019 as there is feature to undo the update and delete statement.

First I tried to update a table with 33609 records, and undo it successfully with 33609 records.
Second attempt, I tried to update another table which has 2847069 rows affected, but undo only works on 100000++ records, which is not as expected.

Is it some limitation on the undo function with trial version? Or did I missed up anything on the undo thing?

Hi, to my knowledge, trial does not have any limitation to this. We are currently testing SQL Server 2019 and implementing new features. It's not yet fully certified.
