Insert Data from to a table
- by Lee_McIntosh
I have a table that lists number of comments from a particular site like the following:
Date Site Comments Total
---------------------------------------------------------------
2010-04-01 00:00:00.000 1 5 5
2010-04-01 00:00:00.000 2 8 13
2010-04-01 00:00:00.000 4 2 7
2010-04-01 00:00:00.000 7 13 13
2010-04-01 00:00:00.000 9 1 2
I have another table that lists ALL sites for example from 1 to 10
Site
-----
1
2
...
9
10
Using the following code i can find out which sites are missing entries for the previous month:
SELECT s.site
from tbl_Sites s
EXCEPT
SELECT c.site
from tbl_Comments c
WHERE c.[Date] = DATEADD(mm, DATEDIFF(mm, 0, GetDate()) -1,0)
Producing:
site
-----
3
5
6
8
10
I would like to be able to insert the missing sites that is listed from my query into the comments table with some default values, i.e '0's
Date Site Comments Total
---------------------------------------------------------------
2010-04-01 00:00:00.000 3 0 0
2010-04-01 00:00:00.000 5 0 0
2010-04-01 00:00:00.000 6 0 0
2010-04-01 00:00:00.000 8 0 0
2010-04-01 00:00:00.000 10 0 0
the question is, how did i update/insert the table/values?
cheers,
Lee
