我正在处理这个查询，在添加了cursor块之后，执行时间从10秒变为2米。
有没有办法缩短执行时间？查询是对同一个表进行3次选择的结果，但条件不同。
我需要光标，因为我应该从一个表中获取一篇文章的价格，该表包含在第一次查询中无法获取的每个日期的价格。

我想这会让你 PrixUnitaire 不需要通过光标。尝试将其添加到提供temp表的三个查询中：

(
    select top 1 CoutAchat from CoutArticle
    where Article = CArticle AND DateCalcul < DateConsommation
    order by DateCalcul desc        
) as PrixUnitaire
