在SAS中将字符串与日期连接起来，例如

Question

I need to create a computed column in SAS with the combination of the string 'ULPDT_' and the result from the today() function. so that my result looks like this: ULPDT_20190101. Here is my non-functional code for the advanced expression:

t1.SourceFile='ULPDT_'||PUT(today(), yyddmmn8.)

Answer 1

year-day-month, YYYYDDMM , is not a normal representation for date, you might actually want year-month-day YYYYMMDD

t1 is indicative of an EG generated join wherein the t1 is a table alias. If you are editing the code of a join node, and the problematic statement is part of a select clause, the correct SQL syntax might be

'ULPDT_'||PUT(today(), yymmddn8.) as t1.SourceFile

Hand coded example (versus EG visual join):

proc sql;
  create table x as 
  select 
    'ULPDT_'||PUT(today(), yymmddn8.) as SourceFile
  from 
    sashelp.class(obs=1)
  ;
