SQL Select data by this week - sql

Question

Hi how do I get the data by current week?
Select * from Transaction where transactionDate ....

Answer 1

In SQL Server based on week of year. Please see DATEPART for ##DATEFIRST etc. for example, this is all trades since Sunday in US/UK settigs:
WHERE DATEPART(week, transactionDate) = DATEPART(week, GETDATE())
Edit:
For Access, use this DatePart and use "ww" for the part of date you want.
In answer to the comment, "week" is not a variable; it's the bit of the date you want
So:
WHERE DatePart("ww", transactionDate) = DatePart("ww", GETDATE())

Answer 2

In Microsoft Access
Last n days:
SELECT *
FROM Transaction
WHERE transactionDate >=Date()-7
If you have indexes and this type of difference suits, it will be faster because it is sargable
This week by week difference:
SELECT *
FROM Transaction
WHERE DateDiff("w",[transactionDate],Date())=0
BTW It is considered bad practice to use *
DateDiff: http://office.microsoft.com/en-us/access/ha012288111033.aspx

Answer 3

Simple but portable:
SELECT *
FROM Transaction
WHERE transactionDate >= ?
AND transactionDate <= ?
Calculate the two parameters in your server-side code to whatever definition of 'week' you need.

Answer 4

In IBM DB2
SELECT *
FROM Transaction
WHERE transactionDate BETWEEN CURRENT TIMESTAMP - 7 days AND CURRENT TIMESTAMP;

Answer 5

In Access, if you want to run a query to find records that fall in the current week, use
SELECT *
FROM table
WHERE table.DateField Between (Date()-Weekday(Date())+1) And (Date()-Weekday(Date())+7);
That runs Sunday through Saturday. Use +2 and +6 instead if you want the workweek.

Answer 6

mySQL (standard date stamp)
SELECT *
FROM Transaction
WHERE WEEK(NOW())=WEEK(transactionDate);
mySQL (unix timestamp stamp)
SELECT *
FROM Transaction
WHERE WEEK(NOW())=WEEK(FROM_UNIXTIME(transactionDate));
Bit of a unoptimized query. Could be a more efficient way.
Note: This isn't a rolling 7 days. Just the current week of the year.
EDIT: Sorry I didn't see the ms-access tag. ignore all of this :|
