Hope this will help,

select id,    
NewsHeadline as news_headline,    
NewsText as news_text,    
state,    
CreatedDate as created_on      
from News    
WHERE CreatedDate >= cast(dateadd(day, -7, GETDATE()) as date)
and CreatedDate < cast(GETDATE()+1 as date) order by CreatedDate desc

Answer 3

DATEADD and GETDATE functions might not work in MySQL database. so if you are working with MySQL database, then the following command may help you.

select id, NewsHeadline as news_headline,    
NewsText as news_text,    
state, CreatedDate as created_on    
from News    
WHERE CreatedDate>= DATE_ADD(CURDATE(), INTERVAL -3 DAY);

I hope it will help you

Answer 4

I don't think you have data for every single day for the past seven days. Days for which no data exist, will obviously not show up.

Try this and validate that you have data for EACH day for the past 7 days

SELECT DISTINCT CreatedDate
FROM News 
WHERE CreatedDate >= DATEADD(day,-7, GETDATE())
ORDER BY CreatedDate

EDIT - Copied from your comment

i have dec 19th -1 row data,18th -2 rows,17th -3 rows,16th -3 rows,15th -3 rows,12th -2 rows, 11th -4 rows,9th -1 row,8th -1 row

You don't have data for all days. That is your problem and not the query. If you execute the query today - 22nd - you will only get data for 19th, 18th,17th,16th and 15th. You have no data for 20th, 21st and 22nd.

EDIT - To get data for the last 7 days, where data is available you can try

select id,    
NewsHeadline as news_headline,    
NewsText as news_text,    
state,    
CreatedDate as created_on      
from News    
WHERE CreatedDate IN (SELECT DISTINCT TOP 7 CreatedDate from News
order by createddate DESC)

Answer 5

To pull data for the last 3 days, not the current date :

date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()

Example:

SELECT *

FROM user_login
WHERE age > 18
AND date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()

LIMIT 10

Answer 6

If you want to do it using Pentaho DI, you can use "Modified JavaScript" Step and write the below function:

dateAdd(d1, "d", -7);  // d1 is the current date and "d" is the date identifier

Check the image below: [Assuming current date is : 22 December 2014]

Hope it helps :)
