I am writing a trigger to inspect a row of a temporary table to determine if
the row has any null columns, I will return as soon as I find a null
column. I ran across this in the manual and It seems like I could use
The FOR-IN-EXECUTE statement is another way to iterate over rows:
[<<label>>]
FOR record_or_row IN EXECUTE text_expression LOOP
statements
END LOOP;
postgresql has a RECORD type which is an abstract row.
Does it have any fields to tell the length?
Does it have an accessor function like new.element(index};
I am trying to write a general function where from instance to instance the
columns in the record change. If I can't do this I will have to create a
new function for each temporary table.
Is this possible or should I quit looking;
FOR record IN {something related to NEW } LOOP
END LOOP;
