Question

I would like to convert an Oracle SQL query into SQL server query.
But I encountered a problem with the following line :

AND to_date(to_char(M_DATE,’DD-MM-YYYY’)) = ’27/01/12′

M_DATE : DATE NOT NULL

I use

to_char(DATE,’DD-MM-YYYY’)

in order to get their data like that : DD-MM-YYYY 00:00:00.000 (data are stocked like : 25/02/12 15:32:06.578)

So I searched on the Internet, but I didn’t find any available solution. But I’m not an experienced SQL user, so if anybody know the solution..

Thanks

Answer 1

In general when removing any time values from a date I would use Date functions rather than converting to string

 DATEADD(DAY, 0, DATEDIFF(DAY, 0, GETDATE()))

instead of

CONVERT(VARCHAR, GETDATE(), 103)

Although the end result is the same you are maintaining date format and while I have no specific results sets to prove it conclusively I have found this to be much quicker when dealing with large quantities of data.
