问题 I am working with Firebird 2.5.8, ODS Version 11.2, connecting via Firebird ADO.NET v6.6 (in C# using Visual Studio).

When logged into the tool, the connection uses the RDB$ADMIN ROLE

问题 Hello I'm working with Firedac (Delphi Seattle) using Firebird (2.5) as a database, when I run this query using a TFDQuery, no records are returned: SELECT ID FROM USERS WHERE PWD = 'êHÆ–!+' The same query within a Database program as IbExpert return one record.
