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.

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!
