SAS proc sql passthrough无限期运行

如何解决SAS proc sql passthrough无限期运行

我有一些周-日期-时间格式的数据，即 14dec2020:00:00:00:000。我正在使用 SAS 和 proc sql (SQL Server) 传递查询

此数据包含数周的数据，但我很好奇是否可以仅提取与当前周相关的数据？ IE 今天是 17dec2020，所以我只想提取 14dec2020 当周的数据。如果今天是 2020 年 12 月 22 日，那么我希望它提取 2020 年 12 月 21 日这一周的数据。

Data macros;
    today = today();
    wkday = weekday(today);
    start = today()-(wkday-1);
    end = today+(7-wkday);
    length cstart cend $22;
    cstart = "'" || put(start,date9.) || ':00:00:00.000' || "'";
    cend = "'" || put(end,date9.) || ':00:00:00.000' || "'";
    call symput ('start',cstart);
    call symput('end',cend);
run;
proc sql;  
    connect to odbc (dsn='x' uid='y' pwd='z');
    create table work.pleasehelp as select * from connection to odbc 
        (select Year,Month,Week,store,sales,SKU
            from datatable
            Where (&start. <= Week and week <= &end.)
            order by SKU);
    disconnect from odbc;
quit;

宏数据集返回正确的日期边界，但当它尝试运行 PROC SQL 时，它会无限期地运行。我运行了 16 分钟，它的 CPU 运行时间只有 1.09 秒。我已尝试将 cstart 和 cend 更改为在整个查询过程中仅开始和结束，但没有匹配。

这里的任何帮助将不胜感激！

解决方法

此示例代码将记录 SAS 生成的传递查询是什么。尝试使用 SQL Server 工具执行相同的查询。

%let start=;
%let end=;

data _null_;
    last_sunday = intnx('week',today(),0);
    next_sunday = last_sunday + 7;

    call symput('last_sunday',quote(put(last_sunday,yymmdd10.),"'")); 
    call symput('next_sunday',quote(put(next_sunday,"'")); 
run;

/* The source code in the macro variables is
   'yyyy-mm-dd'
   and will be understood by SQL Server to be an ISO8601 standard date value
 */
%put &=last_sunday;
%put &=next_sunday;

/* This macro has SQL NOEXEC so you can see in the LOG window what
   the pass through query is.  Try running the same query in a
   SQL Server tool to see what the expected result set is
 */

%macro query;

proc sql noexec;
    connect to odbc (dsn=x uid=y pwd=z);
    create table work.pleasehelp as
    select * from connection to odbc
    ( select Year,Month,Week,store,sales,SKU
      from datatable
      where &last_sunday <= Week and Week < &next_sunday
            order by SKU
        );
    disconnect from odbc;
quit;

%mend;

options mprint;
%query;
