我用Delphi连接ACCESS数据库，库的格式是
NO 1 2 3 4 5 6 7 8 9 10
1 bc ab bc ac abc ac ab bc ac ab
2 ac abc ab bc ac ab ab bc abc ab
3 ab bc abc ab abc ac bc ac abc ac
4 abc ab bc bc ac ab ab ab ac bc
....
怎样在delphi中用程序实现每个字段的组合并存入ACCESS数据库的表中！如从第一条记录抽取每个字段的最后一个字母得到的一个组合为
NO 1 2 3 4 5 6 7 8 9 10
1 c b c c c c b c c b
....
第一条记录共得到2*2*2*2*3*2*2*2*2*2=1536个组合，
然后再到第二条记录，如此到表的最后一条记录！
NO 1 2 3 4 5 6 7 8 9 10
1 bc ab bc ac abc ac ab bc ac ab
2 ac abc ab bc ac ab ab bc abc ab
3 ab bc abc ab abc ac bc ac abc ac
4 abc ab bc bc ac ab ab ab ac bc
