我想在Test1.COL3 = Test2.COL5和Test1.Time = Test2.TIME上使用Test2连接Test1和所需的输出看起来像

我运行以下代码是SAS

  proc sql;
  create table final as
  select * from 
  (
  (select * from Test1) A
  left join
  (select * from Test2) B
  on Test1.COL3=Test2.COL5 and Test1.Time=Test2.TIME
  )  
  quit;

并且我没有得到所需的输出，即使两个数据集中的TIME列长度相同，格式和格式

我的结果是

  Final

  RowID  COL2      COL3     DATE         TIME      AMOUNT     RowID    COL2                 COL3             COL4            TIME    COL5    Amount

I do not understand what is wrong. 

Answer 1

14.14.50 ne 14:14:50

修复您的格式，或使用INPUT将它们都设为数字。

Answer 2

尝试使用

PROC sql;
CREATE TABLE final AS 
SELECT    * 
FROM      ( 
          ( 
                 SELECT * 
                 FROM   test1) A 
LEFT JOIN 
          ( 
                 SELECT * 
                 FROM   test2) B 
ON        A.col3=B.col5 
AND       Replace(A.time,':','.')=Replace(B.time,':','.') )
quit;
