Hi All,
I am having difficulty understanding the use of defaults.
I have a table with defaults defined in three columns. When I run a function
that inserts/or updates records the default value is not written into the
record. I thought this was a result of updates occurring and not inserts.
So, I changed the source table to have the same defaults. However when I use
the COPY command to place data in the source table the defaults do not appear
to be applied there either.
When I run a query on the table specifying WHERE ptos_uom_factor ISNULL I get
lots of records back. I though that using a default would prevent this outcome.
When is the default value applied? On INSERT? UPDATE? COPY? None of the above?
TIA
