Copying date if 'date' matches with the reference

S

Sajjad Qureshi

I have data in different tables. When I collate the two, the two sets
of data doesn't match line by line using the date columns as a
reference. How can I remove non matching rows from the 2nd data set?

Here is how the table looks like.

2/13/1979 2/13/1979 22.894 1.01044
2/14/1979 2/14/1979 22.894 1.01044
2/15/1979 2/15/1979 22.894 1.01044
2/16/1979 2/16/1979 23.064 1.01044
2/20/1979 2/19/1979 23.064 1.01009 'need to remove this
2/21/1979 2/20/1979 23.064 1.01009
2/22/1979 2/21/1979 23.064 1.01009
2/23/1979 2/22/1979 23.064 1.01009
2/26/1979 2/23/1979 23.221 1.01009
2/27/1979 2/26/1979 23.221 1.01033
