Table 1 a total of two columns, rows variable:
A B
C A
B C D


D Table 2 A absolute of two columns,You can not love life forever , rows precarious
01 A
02 A, B, D
03 B, C
04 C, D

If you produce table 3 (N = null)
01 A A N N N N
02 A A B D B B C D
03 B C N N
04 C C D D N N

Table 1 and Table 2, detect out how the data namely equal to the pertinent contact Table 3, Table 2, the second column is the character series.

best no apt use loops and cursors, the best SQL tin be secondhand to directly solve.
