If it's easy to solve in C #, what do you do in SQL? I've never done that before. Open SQL Server Books Online and quickly find a function: DATEADD (datepart, number, date), which functions by adding a period of time to the specified time and then returning. With this function, things can be done much better.
Like what:
Use pubs
GO
SELECT DATEADD (day,21,pubdate) as timeframe
From titles
GO
is to return a value that adds 21 days to the original time of the pubdate field.
The following table is the DATEPART value:
| Date Part |
Abbreviations |
| Year |
YY, yyyy |
| Quarter |
QQ, Q |
| Month |
MM, M |
| DayOfYear |
Dy, y |
| Day |
DD, D |
| Week |
WK, WW |
| Hour |
hh |
| Minute |
MI, n |
| Second |
SS, S |
| Millisecond |
Ms |
specifically to my question, need to be on the basis of the original record minus 15 minutes, the condition is all this morning late attendance record, see the following sql:UpdateKaoqin
SetSj=DateAdd(MI,-
the, SJ)
where(SJ>'2007-8-15 08:00:00'Subtract time only needs to set number to the corresponding negative value on the line.
SQL Date Time format conversion large complete, SQL plus minus one months, plus minus one day, SQL time format conversion.
