789             w, xyz

输出1

AccountNumbers  Loans
123             abc
123             def
123             ghi
456             jkl
456             mnopqr
456             stuv
789             w
789             xyz

输入2

AccountNumbers  Loans
123             15-abc
123             15-def
123             15-ghi
456             99-jkl
456             99-mnopqr
456             99-stuv
789             77-w
789             77-xyz

输出2

AccountNumber   Loans
123             15-abc, 15-def, 15-ghi
456             99-jkl, 99-mnopqr, 99-stuv
789             77-w, 77-xyz

我管理从输出1获取输入2，现在只需要输出2.

我真的很感激帮助。

谢谢！

Answer 1

尝试此操作，将[输入2]替换为输入2表的实际名称。

data output2 (drop=loans);
    do until (last.accountnumbers);
        set [Input 2];
        by accountnumbers;
        length loans_combined $100;
        loans_combined=catx(', ',loans_combined,loans);
    end;
run;
