I am migrating a project from Delphi XE with UniDAC 4.5.10 to Delphi Alexandria with UniDAC 9.2.1 and I am getting a few errors on Query.Open. These are the errors and I don’t have them in the old project.
1. illegal constraint expression
2. object was open.
3. object was open. Cannot execute command in current transaction context until previous opened DataSet (cursorType is ctDefaultResultSet) is fetched to end
All errors are on different random queries. I have noticed that in UniDAC 4.5.10 there is not a cursorType propertie. Do you have any idea how can I solve my problem?
