Question

I want to

• Insert a new row into my table if it does not exist
• If key already exits, then update the entries but only if the field timestamp date is newer then the stored filed. I tried this with sqlite but it gives me an error near where. Im also not sure if this is correct and how to do it properly.

code:

String sql = "INSERT OR REPLACE INTO "+TABLE_USER+" (...)" +
     " VALUES ('"..."'" + 
     ") WHERE " + timestamp + 
         " > (select " + COLUMN_TIMESTAMP + 
         " from " + TABLE_USER + " where " + COL_NUMBER + " = '" nr + "')" 

Answer 1

Insert or replace does not allow a where clause. I guess you have to do it in two steps.
