Hi Richard, Thanks for the quick reply.
So what I am confused is, if there is a Write (update) operation and it creates a WAL file and subsequently a read operation comes in and the read is trying to access the same data what write is working on. Does in this scenario read will wait or it will grab the data from the original database file which is not really data?

Please help me to improve the documentation for SQLite by telling me what you read in the documentation that lead you to believe that WAL mode gaves dirty reads? -- D.
