Hi,
Does anyone know why when I join two tables by the
name of the column the rows which contain the duplicates are overwritten?,
i.e.
I have two tables which consist of the same number
of rows, and columns with the same name and respectively the same names of
the properties in rows. Some properties have the same name but different
reference number, therefore the name has to be duplicated. The spatial objects
for the duplicated names were created and added to the table which stores the
spatial data. Of course I can join the tables on ID(this works), but I am not
really sure that IDs will be "compatible" with each other and checking the data
manually is very time consuming and at the same time I cannot assure myself that
my eye is perfect
Thanks,
Ewa |
