3.从固定的位置开始获得固定长度的字符串:substr(s,p,n). 从字符串s中的第p个字符开始抽取n个字符长的子串. 4.scan函数:scan(string,i,"char") 表示从字串string中以char为分隔符提取第i个字串。其中char可以是多个字符组合。 如:datawork.test; Title = 'A Tale of two Cities,Charles j.Dickens'; ...

Sets the designated parameter to the given Java boolean value. The driver converts this to an SQL BIT value when it sends it to the database. The IOM JDBC driver supports this method for NUM columns, but does not support it for CHAR columns. Specified by: setBoolean in interface java...
做做merging, combine, convert time format, subset data(尤其是从几十万的数据库里调用需要的数据和变量)完全是小case. 这一点私以为stata的功能是远远比不上的。sas里面还可以run sql. 如果需要join多方面来源的复杂数据,sql的功能是远高于stata的。 R的强项在于数据分析和数据可视化(同stata相似),并且这两项...
(3)将Excel文件中的变量LABEL转换为SAS 变量label,并去除空格;(4)将Excel中的变量LENGTH转换为SAS变量length,并去除空格;(5)将Excel文件中的变量TYPE转换为SAS变量 type,并将TYPE类型转为SAS专有的”Number“或”Character“两种。(6)创建宏变量keepstring,将所有的variable读取进去,以”|“间隔。 生成数据集EMPTY...
