This is a prototype I wrote a while back that takes a source SQLite database and clones it to another SQLite database - in this case an in memory SQLite database. The code is prety straight forward, initialize the source (from) and destination (to) SQLite databases and call the CopySQLiteDB sub.

sqLite queries can have parameters which can also be tested. A typical subroutine to create a DB and create a table within it are shown below: '============================================================================================ Public Sub tuningVarsSQL_Init If tuningVarsSQL.IsIn

That's why the below 'Try' block with the SQL operations is there, ' and why it doesn't just open the database. A successful File.Delete is inconclusive. File.Delete(dir, fileName) Catch Return True End Try End If Try Dim sql1 As S

Don't use InitializeSQLite. Use Initialize or Initialize2. Something like sql.Initialize("com.sqlite.JdbcUrl","jdbc:sqlite:test.db") That should open an unencrypted test.db SQLite database file that is located in the same directory as the the program file (.jar) or, while developing, in the Object
