Answer 1

Make sure your connection is not Active in design time.

In FormCreate (or DataModuleCreate) you can do

Sql_componentname.DatabaseName := ExtractFilePath(ParamStr(0)) + 'yourdb.gdb';
Sql_componentname.Active := true;

This is if your db is in the same directory as your program. Otherwise you could set it elsewhere (from ini or userdirectory)

Otherwise: Via an inifile in your applicationdirectory you could do this

iniFile := TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini')) ;
try
  Sql_componentname.Databasename := iniFile.ReadString('Server','DatabaseName','') ;
finally
  iniFile.Free;
end;

And in the ini

[server]
databasename=projectFolder/store/db.fdb
