Re: duplicate key violates unique constraint

Shavonne,
You will probably always find someone on the list who will answer your
questions, but you really should read the manual too!
In this case you could have found the answer by reading

Thank you. I tried as you said. But i get a ERROR: syntax error at or
near
"INSERT" at character 9

BEGIN
INSERT INTO my_shevi values ('a', 4, 2, 2);
EXCEPTION
WHEN unique_violation THEN
INSERT INTO my_shevi values ('a', 5, 2, 2);
END;

I don't see anything wrong with the code..
