Question

我正在尝试在SAS中运行PROC SQL步骤但由于某种原因继续遇到错误。这是我的代码：

PROC SQL; 
    CREATE TABLE NewTable AS
        SELECT a.ID as ID, 
            a.Group as Group, 
            a.2014_04,
            b.2014_04,
            c.2014_04,
            b.2014_04/a.2014_04,
            c.2014_04/a.2014_04
        FROM work.TESTDATA a
        LEFT OUTER JOIN work.TESTDATA_0000 b on a.ID
        LEFT OUTER JOIN work.TESTDATA_0001 c on b.ID;
QUIT;

我收到的错误如下：

ERROR 22-322: Syntax error, expecting one of the following: a name, *.  

ERROR 200-322: The symbol is not recognized and will be ignored.

这些错误似乎集中在变量上。错误是否与我引用变量的方式有关？

在SAS中，变量名必须以字符或下划线开头。因此，您的2014_列在SAS中无效。

试试这样：

PROC SQL; 
    CREATE TABLE NewTable AS
        SELECT a.ID as ID, 
            a.Group as Group, 
            a.'2014_04'n,
            b.'2014_04'n,
            c.'2014_04'n,
            b.'2014_04'n/a.'2014_04'n,
            c.'2014_04'n/a.'2014_04'n
        FROM work.TESTDATA a
        LEFT OUTER JOIN work.TESTDATA_0000 b on a.ID
        LEFT OUTER JOIN work.TESTDATA_0001 c on b.ID;
QUIT;

'<invalid_sas_var_name>'n允许您仍然使用原本无效的SAS变量名称

符号/语法无效
