将datetime添加为参数会在存储过程中将数据类型varchar转换为datetime（Error）时出错

Question

我有一个stored procedure接受一个参数作为@ReportDate。

但是当我用参数执行它时，它会给出错误

这是SP。

我正在执行这样的EXEC GET_EMP_REPORT '16/05/2016'

输入的当前日期格式是DD/MM/YYYY，它给出了错误。执行它作为MM/DD/YYYY工作，但我宁愿执行它作为DD/MM/YYYY。

但得到错误

我正在使用SQL-server-2005

Answer 1

EXEC GET_EMP_REPORT '20160516'

以通用格式'yyyyMMdd'传递日期

Answer 2

如果您对Date and Time Styles有自己的偏好，那么最好通过预先设定首选样式来使用CONVERT函数，例如： DD/MM/YYYY。

DECLARE @ReportDate DATETIME = CONVERT(DATETIME, '16/05/2016', 103)
EXEC GET_EMP_REPORT @ReportDate

要么

DECLARE @ReportDate DATETIME = CONVERT(DATETIME, '16/05/16', 3)
EXEC GET_EMP_REPORT @ReportDate

Answer 3

DECLARE @ReportDate DATETIME
SET @ReportDate ='31/12/2016' -- DD/MM/YYYY Format you cant insert . It will give the below error

将varchar数据类型转换为日期时间数据类型会导致超出范围的值。

如果你真的需要以DD / MM / YYYY格式插入相同的内容。将@ReportDate声明为Varchar.Please参考下面的代码。

DECLARE @ReportDate VARCHAR(10)
SET @ReportDate ='31/12/2016' 

SELECT * FROM MyTable WHERE MyColumn BETWEEN CONVERT(DATETIME, @ReportDate, 103) AND GETDATE()

Answer 4

其他答案有效，但在我看来更简单的声明：

SET DATEFORMAT dmy;
EXEC GET_EMP_REPORT '16/05/2016'
