Function parameter

P: n/a
Hi there,

I need to do something like this:

-- Function: public."ModifyOrder"(int4, text, int4)
CREATE FUNCTION public."ModifyOrder"(int4, text, int4) RETURNS void AS
'UPDATE orders SET $2 = $3 WHERE "OrderId" = $1;' LANGUAGE 'sql'
COMMENT ON FUNCTION public."ModifyOrder"(int4, text, int4) IS
'ModifyOrder(OrderId, FieldToUpdate, NewValue)';

where parameter $2 will be a text value that represent a column name.
Is there any way to do something like that?

I just want to be able to change values of several columns using this
function, writting something like this:

ModifyOrder(19283, "DestinationId", 5);

so that it will update the record with OrderId = 19283, and change
DestinationId to value 5.
