Sqlite: Insert if not exist, Update if exist

Question

I have a database with 2 tables like this:

cg_resp
id  | name   | email
1   | George | george@yahoo.com

id column is primary

Answer 1

SQLite has no built-in mechanism that would not delete the existing row.

The easiest way to do this is to put the logic into your application:

cursor = db.execute("SELECT ...")
if cursor.empty:
    db.execute("INSERT ...")
else:
    db.execute("UPDATE ...")

If your language allows to read the number of affected rows, it is possible to do this with two SQL commands:

db.execute("UPDATE ...")
if db.rowcount == 0:
    db.execute("INSERT ...")
