Please, bear with me, as this is my first post here.
(1) I have a 2 table database, result of a conversion from Access. This has
been made by an amateur, as one of the tables should be at least 3 related
tables, bunch of redundant data,and the other one 2.
I know I could create a table as the result of a request, so that I could
isolate these redundant data, but what I don't know is how I would in the
same time update the original table to put the ID of the matching ROW
number in the newly created table, instead of the redundant data ?
Should I create a stored procedure for that, and if yes, how ? Or should I
do that in 2 passes, sequentially ?
(2) How should I go to create a sequence for an existing table? For all
futures data entry, after this conversion, I want the unique ID for each
row to come from a sequence, but if I know how to create a table using
serial, I am not sure how to modify one for this.
Thanks,
Bernard
