对数值型变量,因为SAS里默认长度就是8,所以不需要再写length语句。 注意,如果length语句放在set语句之前,那么length后面的变量会依次出现在数据集最左边,这样方便查看新生成的变量做的是不是对,而且可以重新设定一个变量的长度。 实际上,依据FDA e-submission的法规要求,...
the valid lengths are usually 3 through 8. The longer the length, the greater the precision allowed within the column values. For character columns, the length can be 1 through 32767. For single-byte
The LENGTH function returns an integer that represents the position of the rightmost non-blank character in string. If the value of string is blank, LENGTH returns a value of 1. If string is a numeric constant, variable, or expression_r(either initialized...
Correct answer: b The TRIM function removes trailing blanks from character values. In this case, extra blanks must be removed from the values of FirstName. Although answer c also works, the extra TRIM function for the variable LastName is unnecessary. Because of the LENGTH statement, all ...
如果原始文件data file的前20行含有所有的缺失值或非典型值(missing value or non-representative data),则使用GUESSINGROWS,(guessingrows)语句以确保变量被分配了正确的data type 和length。 开始读取行datarows=n; melimiter='delimiter-character'指定文件中使用的Delimiter。

You can use the MODIFY clause to change a column's 1:length (column width) - for a character column only 2:informat 3:format 4:label. 不能更改列的类型,比如char->num 不能更改列名 /*modify列*/ procsql;altertablework.payrollmaster4 ...
char_lengths - I've added a BPC (bytes per character) value to my lookup table for all of the SAS encodings. In the cases where BPC is 1 (single byte encodings), I can optimize out the transcoding to bytes of the SAS encoding from the length calculations, and only calculate char leng...
