Hi ,
I have created this function to remove UserDataAccountid
from both tables
UserAccountDetails and UserAC
CREATE OR REPLACE FUNCTION DeleteUserData(ACDetailsID int[])
RETURNS void AS $$
DECLARE _id int;
BEGIN
-- postgresql has no table type, use a int array instead
FOR _id IN array_lower(ACDetailsID,1) .. array_upper(ACDetailsID,1)
LOOP
DELETE FROM UserAccountDetails WHERE UserDataAcountId=
_id;
DELETE FROM UserAC WHERE UserDataAcountId= _id;
END;
END LOOP;
EXCEPTION WHEN OTHERS THEN
RAISE WARNING 'some issue %', SQLERRM;
END;
$$ LANGUAGE plpgsql;
Now I am calling this function to delete userdataacountid
from both tables, say i have a user with userdataacountid '5', how can i delete
this user by calling this function , i have tried
select DeleteUserData(5);
and
select * from DeleteUserData(5);
its not working ,
thanks

I would guess that the error you're getting is:
ERROR: function deleteuserdata(integer) does not exist
LINE 1: select DeleteUserData(5);
^
This is happening because your function takes an array, not a single
integer. PostgreSQL can automatically cast from a string to an array if
the string is properly formatted:
select DeleteUserData('{5}');
Hope this helps.
