How to add a row number based on criteria in SAS Enterprise Studio?
问题
这是我尝试的代码：
data add_row_count;set LIB.Table1;count + 1;by ID OTHER_DATE;if first.OTHER_DATE then count = 1;run;
这将根据每个唯一的 "ID" 和 "OTHER_DATE" 列的第一个出现的行设置计数器，并在每个新的 "OTHER_DATE" 值开始时将计数器重置为1。希望这可以帮助您得到期望的结果。
英文:
I have a table like this:
ID OLD_ACCOUNT NEW_ACCOUNT DATE OTHER_DATE20 001 002 1/1/2023 1/1/202320 002 003 2/1/2023 2/1/202320 002 004 4/1/2023 2/1/202320 003 004 4/1/2023 4/1/202330 101 102 1/2/2023 1/2/202330 102 103 2/2/2023 2/2/2023
I am trying to add a row number that starts at 1 at the first iteration of a new "OTHER_DATE" for each unique "ID". So the new column would look like this:
ID OLD_ACCOUNT NEW_ACCOUNT DATE OTHER_DATE COUNT20 001 002 1/1/2023 1/1/2023 120 002 003 2/1/2023 2/1/2023 120 002 004 4/1/2023 2/1/2023 220 003 004 4/1/2023 4/1/2023 130 101 102 1/2/2023 1/2/2023 130 102 103 2/2/2023 2/2/2023 1
This is the code I tried:
data add_row_count ;set LIB.Table1;count + 1;by ID DATE OTHER_DATE;if first.OTHER_DATE then count = 1;run;
This is returning a 1 for every row which is not what I need. Thank you in advance

这段代码是关于操作顺序的可能性。这对你有什么帮助吗？
data add_row_count ;set LIB.Table1;by ID DATE OTHER_DATE;if first.OTHER_DATE then count = 1;else count+1;run;
