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....
I want to import a tab delimited file into sas. there are a variable containing percentage values, like 6.9873% or -12.0945%. SAS recognizes this variable as character when I import the file. I need this variable to be numeric, so I did the following: newvar=input(oldvar,percent...
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 ...
2. Simply change the informat toB8601DJ(reads Java datetime) becauseit does not require aTin the datetime value. 3. When theB8601TMinformat specifies a width larger than the value being read, an incorrect result may be created. For example, specifying B8601TM8. to read a value with a w...

This type of error is most likely to occur in cases of character-to-numeric variable conversion, most especially when the user does not fully understand the data contained in the data set. This paper will review the basics of data storage for character and numeric variables in SAS, the use...

PROC IMPORT做的事有:(1)扫描你的data file(默认20行),并自动决定变量的数据类型(character 或 numeric)。(2)给字符变量分配长度(assign lengths to the character variables) (3)可以识别一些特殊的日期时间格式(如DATE11.)。(4)将连续的delimiters 看作事一个缺失值(missing value)。(5)将引号包围起来的部分...
