SAS proc 导入缺少前导零
我正在尝试使用 proc import ( SAS ) 将数字从 csv 文件导入到 sas 数据集，但导入后所有前导零都消失了。
例如，
导入后“0123456”我只会得到“123456”

For example,
'0123456' after import I would get only '123456'

如果您将它们作为数字字段读取，则只需对变量应用一种格式即可显示前导零。请记住，数字 012345 相当于数字 12345，因此没有理由存储前导零。尝试一下格式
. To display the zero in your example above.
If you really need the zeroes for some reason, and the number of digits is arbitrary, then you need to read them in as character variables instead.
If you are reading them in as numerical fields, you just need to apply a format to the variable to display the leading zeroes. Remember, the number 012345 is equivalent to the number 12345 so there's no reason to store the leading zero. Try the format
