Hi Everyone
My question is, is it possible to create a referential integrity constraint
on an exisiting, already populated, table??
My reasons for this are:
I am trying to copy two delimited text files into a database using the COPY
command. The first file - with about 280,000 lines - takes about 5-10
minutes to copy. The second file - with about 89,000 lines - is still
running after 4 days!
This second table has refrential integrity constraints on 3 fields (it's a
15 field table)
I have also copied this file into a table with no refential integrity
constraints and then used an INSERT command to copy the records into the
correct table. This is also taking days.
So, if I can't copy this file into a table and then apply the referential
integrity constraints, can anybody help me work out what my options are?
Thanks
Adam Fisher
