How to ensure whether the row is successfully inserted

Question

HI All,
Is there any means of ensuring whether the row was successfully inserted or not?
I want to insert a row into a table and if it is successfully inserted I want to return the return code as 0 else some error code.
Also I am selecting a value into a variable from the join of 3 records and the select is supposed to return a unique value.
What I want to ensure is if at all it is returning a row of not and if not then pass other value(say null)
What I have done is I have taken the result into a cursor and I loop through it because I know that the cursor proceeds if it finds a null as the resultant row. But I know it is not a good method.
What else can I do?
Regards,
Amit

Answer 1

a basic example would look something like this
Create Or Replace Procedure Your_Procedure_Name (pErrNum Out Number) Is
Begin
  Insert Into Your_Table_Name
   (col1, col2, col3)
  Values
   (pCol1, pCol2, pCol3);
  -- return 0 means successfull
  pErrNum := 0;
Exception
  When Others Then
    -- return the errorcode
    pErrNum := SQLCODE;
End;
