iOS Question The FMDatabase <FMDatabase: 0x283be9770> is not open.

[DeclanOK]

Writing a small SQLite based app,. I am sorry about formatting

The FMDatabase <FMDatabase: 0x283be9770> is not open.

Code is here and error happens last line

Sub FillSubjectTable
TableViewSubjects.RowHeight = 50
Log("Fill Subject table")
Dim SubjectList As List
If Main.SQLMainQ.IsInitialized = False Then Main.SQLMainQ.Initialize(File.DirDocuments, Main.db_questions, False)
Dim RSS As ResultSet= Main.SQLMainQ.ExecQuery( "SELECT DISTINCT(subject) FROM " & Main.tablechosen & " Group by subject;"

The app crashes on the last line

There is also an out of memory error in the logs. That might be the real error.

Do other queries work?
