You shouldn't just skip column 11. If you don't want to bind a value to it, use sqlite3_bind_null . But given that you only have 13 columns and you're binding using indexes up to 14, I'm presuming you removed isNotification , so perhaps you want to renumber indexes 12-14 to be 11-13? Bottom line, check the result of the sqlite3_bind_xxx calls and it would have caught this, methinks.

Also, btw, do not call sqlite3_reset . (That's for resetting a prepared statement so that you can bind new values in order to call sqlite3_step again.) You should instead use sqlite3_finalize .

If you're still having problems, tell us what the exception was. Or if you're not going to share that with us, refer to My App Crashed, Now What? . And I understand why you may have added exception handling, but that's not a preferred error handling mechanism in Objective-C and I'd remove it so that you an see what the full stack trace and full details of the exception in the debugger.
