SAS 4GL的sql如何加入

Question

我在編程是新表，我必須做一些任務，看起來像這樣： 我有例如兩個表：

表A

+-------+ 
| name | 
+-------+ 
| name1 | 
| name2 | 
| name3 | 
+-------+ 

表B

+-------+-------+ 
| name | tips |

| name1 | tips2 | 
| name1 | tips3 | 
| name2 | tips4 | 
| name2 | tips5 |

現在我想有一個表是這樣的：

表C

+-------+---------------------+ 
| name |  tips   | 
+-------+---------------------+ 
| name1 | tips1, tips2, tips3 | 
| name2 | tips4, tips5  |

Answer 1

data TableC; 
    set TableB; 
    by name; 

    length t_tips $ 1000; 
    retain t_tips; 

    if (first.name) then 
     do; 
      t_tips=strip(tips); 
     end; 
    else 
     do; 
      t_tips=strip(tips) ||", "||strip(t_tips); 
     end; 

    if (last.name) then output; 
    drop tips; 
run;
