sql - 将数值转换为数据类型数值时出现算术溢出错误

Question

每次运行此查询时，我都会收到此错误消息:

Msg 8115, Level 16, State 8, Line 33
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.

但是如果我将创建表更改为 (7,0)，我不会收到错误消息。但我需要将数据显示为小数。我试过8，3不行。

DECLARE @StartDate AS DATETIME
DECLARE @StartDate_y AS DATETIME
DECLARE @EndDate AS DATETIME
DECLARE @temp_y AS DATETIME

SET @temp_y = Dateadd(yy, Datediff(yy, 0, Getdate()), 0)
SET @StartDate_y = Dateadd(dd, 1 - Datepart(dw, Dateadd("ww", -2, @temp_y)),
                                      Dateadd("ww", -2, @temp_y))
SET @StartDate = Dateadd(dd, 1 - Datepart(dw, Dateadd("ww", -2, Getdate())),
                                  Dateadd("ww", -2, Getdate()))
SET @EndDate = Dateadd(dd, 6, @StartDate)

我的猜测是您试图将大于 99999.99 的数字压缩到小数字段中。如果它大于 99999.999，则将其更改为 (8,3) 不会执行任何操作 - 您需要增加小数点之前的位数。您可以通过增加精度(即小数点前后的位数)来实现此目的。您可以保持比例不变，除非您需要更改要存储的小数位数。尝试 decimal(9,2) 或 decimal(10,2) 或其他。

您可以通过注释掉 insert #temp 来测试这一点，并查看 select 语句为您提供的数字，并查看它们是否大于您的列可以处理的大小。
