We know Format is a common function to convert date in SAS, such as,format aestdt date9.. What aboutProc Format? When and how should we use it? Case 1: Numeric to Character Presentation When data are coded in numerical, we would like to display it in characters in Frequency tables. S...
When converting a string to a numeric value, note the encoding of the string. When the string is a single-byte encoding, DS2 translates the value to a TKChar (UCS-2 or UCS-4) for conversion. The longer the string, the longer the time it takes to do the conversion....
sas 合并不了,提示错误为:ERROR: Variable ___1 has been defined as both character and numeric. 答案 这是因为你的合并变量在两个来源数据集中定义的类型不一致,一个是字符型,另外一个是数值型.需要重新定义类型,比如说用format语句. 相关推荐 1 sas 合并不了,提示错误为:ERROR: Variable ___1 has ...
