在SQL Server 2005 Express中查询日期时间

Question

How to query the rows based on DateTime in SQL Server 2005 Express installed on windows server 2008 r2?

I have code that selects rows based on from and to date values. It's working in my Windows 7 system . But, It's not working on Windows Server 2008 R2 ... Any help

this.filterreportTableAdapter.FillBy(this.cRdataset.filterreport_datatable, fromdate, todate);

and my SQL query is

SELECT * 
FROM tablename 
WHERE DATE BETWEEN @fromdate and @todate

Answer 1

It sounds like date/time values are being passed as strings. This is always a bad idea, and formatting issues abound. The best approach here is simply: use correctly-typed parameters. if both client and server know it is a DateTime, then it is passed as a primitive vaue, not a string - thus no formatting problems.

Make sure that fromdate and todate in the c# are DateTime , and that @fromdate , @todate and tablename.DATE in the TSQL are datetime .

Answer 2

请设置与Windows 7上相同的日期时间格式，例如：dd / MM / yyyy

Answer 3

it seems that you have a date format mistake when passing date parameters. there are two solutions: first, you can try to use date format that works everywhere that is: YYYYMMDD ex : 20120722. another solution is to make a DateDiff in sql query Best regard
