how store primerykey in sqlitedatabase in iphone - iphone

Question

I am creating a database to store the value in table with a primary key but I am getting a problem with the primary key. It is not taking. If I enter the first time it's shown in the database record but if I enter a second time the record is not showing in the database. My application shows bad access in the console.

Answer 1

You have to release your newobj not the array.
Replace this:
[appDelegate.journeyList release];
with this:
[newobj release];
