我试图使用proc sql汇总我的数据集,但我在输出中重复了一个值,我的代码的一个简单版本是:
PROC SQL;
CREATE TABLE perm.rx_4 AS
SELECT patid,ndc,fill_mon,
COUNT(dea) AS n_dea,
sum(DEDUCT) AS tot_DEDUCT
FROM perm.rx
GROUP BY patid,ndc,fill_mon;
QUIT;
一些示例输出是:
Obs Patid Ndc FILL_mon n_dea DEDUCT
3815 33003605204 00054465029 2000-05 2 0

正如你所看到的,有重复输出,例如obs 3815,3816。我看到有些人有类似的问题,但答案对我没有用。

我猜你有变量的格式,很可能是日期。 Proc SQL不会聚合格式化值,但会使用基础值,但仍然将其显示为格式化,因此它们显示为重复值。你的proc内容证实了这一点。你可以通过将变量转换为字符变量来解决这个问题。
function onMouseUp(event) {
console.log('vup');
}
