"also checked that primary key is not repeated from my side" - nevertheless,you are trying to insert a record with a primary key that already exists on that database

if your 'primary key' is "auto inc : A.I", don't write the belonged field in your "insert" query.
the Db engine will do it for you.

Primary keys must - by definition - be unique: you cannot enter a second PK that has the same value - and the error message is pretty explicit about this.

So start by looking at your values and how you INSERT them to the DB; check that you are using the DB you think you are; that you are using the table you think you are; and look closely at your code to find out how you are passing the data to the DB Engine.

The DB Engine doesn't raise this error spontaneously: it is being passed a PK field value that would duplicate an existing one!

Sorry, but we can't help you fix this: we have no access to your DB, your data, or your code - and you need all three to start working this out!
