查找前x天的记录？

Question

如何设置选择过去30天结果的存储过程？

where MONTH(RequestDate) > 6 and DAY(RequestDate) >= 10 
and MONTH(RequestDate) < 21 and DAY(RequestDate) < 7

Answer 1

SELECT *
FROM Table
WHERE GETDATE() >= DATEADD(DAY, -30, GETDATE())

用适当的列名替换第一个GETDATE().

SELECT *
FROM Table
WHERE Table.ColumnName >= DATEADD(DAY, -30, GETDATE())
