Re: Combining data from Temp Tables

Obviously my formatting did not post correctly the first time. Here is another attempt, with the desired result table listed:

Temp Table 1
DATE LN MBRID DS
1/1 A 1 30
1/1 A 1 30
1/1 B 1 30

1/1 A 2 30
1/1 A 2 30

1/1 C 3 45

1/1 D 4 45
1/1 D 4 45

Temp Table 2
DATE LN MBRID DS
1/1* A 1 -30

1/1* A 2 -30
1/1* A 2 -30

1/6* D 4 -45

*including and up to five days after Temp Table 1 DATE
Temp Table 3 (desired)
DATE LN MBRID DS
1/1 A 1 30
1/1 B 1 30

1/1 C 3 45

1/1 D 4 45

Thanks again.

Subject: [GENERAL] Combining data from Temp Tables

Hi all,

I have created two temp tables that I would like to combine to make a third temp table and am stuck on how to combine them to get the results I want. Any guidance you could give would be appreciated.

Temp Table 1 Temp Table 2
DATE LN MBRID DS DATE LN MBRID DS
1/1 A 1 30 1/1* A 1 -30
1/1 A 1 30
1/1 B 1 30

1/1 A 2 30 1/1* A 2 -30
1/1 A 2 30 1/1* A 2 -30

1/1 C 3 45

1/1 D 4 45 1/6* D 4 -45
1/1 D 4 45

*including and up to five days after Temp Table 1 DATE

I would like the Temp Table 3 to hold only the BOLD records above. In essence, it would compare and erase a record at a one to one ratio based on some fields being identical and the date range being on or within the next five days of Temp Table 1 date.

Thanks!
