如何在C＃Windows Form应用程序中获取SQL Server中今天插入的数据的记录

Question

I am developing an app in VS2010 c# to fetch a single row data from SQLServer and insert it to MySQL.

In this I have to check that how many records inserted today with one SQL Server query in SQL Server table name RAW_S001T01.

I have tried to Google it but not getting exact answer. I tried below query

SELECT        Date_Time
FROM            RAW_S001T01
WHERE        (Date_Time = { fn CURDATE() })
ORDER BY Date_Time DESC

but not getting correct output.

Please help me with correct query.

Thanks in advance.

Answer 1

If you only want records in RAW_S001T01 where Date_Time column is equals to the today date, you can modify your WHERE clause like this :

SELECT        Date_Time
FROM          RAW_S001T01
WHERE         Date_Time = CONVERT(date, getdate())
ORDER BY      Date_Time DESC

GETDATE() is an SQLServer function which will return the today date, like 2013-11-20 14:05:54.943 . Cast it in DATE to only keep the date part, ie 2013-11-20 .

Answer 2

If I've understood your question, you only need to count the number of records added today by the Date_time column. Hope I'm not mistaken.
Try this;

SELECT        Count(Date_Time) as No_Of_records_today
FROM          RAW_S001T01
WHERE        (Date_Time = getdate())

Thanks for your suggestions got correct answer ie

SELECT Date_Time FROM RAW_S001T01
WHERE  Date_Time >= CONVERT(DateTime, DATEDIFF(DAY, 0, GETDATE()))
ORDER BY Date_Time DESC
