NexusDB UniConnection cannot connect to remote server without empty database

Post by VojkoCendak » Thu 23 Apr 2020 13:46

Hi, (NexusDB4 pro, Delphi XE5 ent)

Is this as designed ?
Problem: we want to create new alias (from SQL DDL)
1. connect to server ==> here it throws "unknown database" if we have Server specified "NexusDB@127.0.0.1"
2. then create alias ...

Thank you
Vojko Cendak

Are you able to connect to the server without specifying the database name and then run the DDL to create an alias using the standard NexusDB components?
If you're able to connect to the server, please describe how you do that.

You can connect to an in memory database by using
#inmemdbname for the database AliasPath and go from there.

(answer from Nexus team);

We have already fixed the issue, the fix will be included in the next UniDAC. In the new build, an #INMEM alias is created automatically when it is specified in the Database property. Therefore, in the new build, to solve the issue, you can set the Database property to #INMEM.
Please specify your IDE version and we'll send you the nightly build of UniDAC that includes the fix.
