Hi Michael,
Good question :-)
I am writing a function that has a row of data passed into it as variables
and an ID. The function needs to pull out the appropriate row of data and
compare each data item which those passed in. For each found difference a
log row is written somewhere else and if there are *any* differences the
whole row is updated.
I was building an array from the passed in parameters with ||, then I wanted
to build an array from a query (with SELECT INTO) and then compare each
value with a loop:
FOR i IN 1..17 LOOP
-- compare current with new data
if CurrentData[i] is not NewData[i] then
ChangeFound := true;
-- load change into log table
Make sense? Thanks again,
G.
