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 ...

When creating variables, do not use the names of special SAS automatic variables (for example, _N_ and _ERROR_) or special variable list names (for example, _CHARACTER_, _NUMERIC_, and _ALL_). The maximum length of a variable is 32 bytes. The first ch...
One of the first lessons that SAS(R) programmers learn on the job is that numeric and character variables do not play well together, and that type mismatches are one of the more common source of errors in their-otherwise flawless-SAS programs. Luckily, converting variables from one type to ...
_CHARACTER_:表示数据集所有字符变量 _NUMERIC_:表示数据集中所有数值变量 这些名称列表在要计算某观测的所有数值变量的均值时(MEAN(OF _NUMERIC_)),或列出某观测所有变量的值时(PUT _ALL_)非常有用。 datazdata.songs;infile"D:\data\sas_file\songs.dat";inputcity $ 1-15 age wj kt tr filp ttr;array...
