I have to query 10 days data from snowflake database. I tried the date between '2019-07-30' and '2019-08-09' which includes start and end date?
Dates should be in single quotes as such:
Date >= '2019-07-30' and Date <= '2019-08-09'
You can also use between as you mentioned:
Date between '2019-07-30' and '2019-08-09'
Adding this into your WHERE clause will seperate results between these two dates
If you want to include all dates including today going back 9 days (so 10 total days) then try using this WHERE clause:
WHERE date >= DATEADD(DAY, -9, CURRENT_DATE()) AND
date < DATEADD(DAY, 1, CURRENT_DATE())
This says to match dates which occur on or after midnight of 9 days ago, up until any date strictly before midnight of tomorrow (implying all of today matches).
Here's the BETWEEN Snowflake documentation, and it reads:
"The expression A BETWEEN X AND Y is equivalent to A >= X AND A <= Y"
use below Query
SELECT * FROM snowflake WHERE start_date >='2019-07-30' and end_date <= '2019-08-09';

Hope someone can help me out. I'm trying convert a line of SQL to work with Presto. Currently in SQL I do the following to get all records that are due in the next 0-5 days:
((EventStartDate)between getdate()-1 and dateadd(day, 5, getdate()))
I thought it would be something like this in Presto
EventStartDate between current_date and interval '5' day
But get the following error in AWS Athena: Cannot check if date is BETWEEN date and interval day to second
Thanks,
Mark
Interval needs a date or timestamp to be used and BETWEEN can only be made between to equal entities to dates twp timestamps two numbers
So do this instead
EventStartDate between current_date and current_date + interval '5' day
I'm trying to get the data between last weeks monday and last week sunday. I'm having trouble with getting the relative part. I'm trying like this:
where date <= LASTWEEKSUNDAY OR date >= LASTWEEKMON
The closest I got to what I seek was using now(), but it returned also some days from the current week. Thanks in advance
You are describing:
where date >= date_sub(date_trunc(current_date, week(Monday), interval 1 week) and
date < date_trunc(current_date, week(Monday))
Although the function calls change, the same logic works on datetimes and timestamps.
Of course week(Monday) is the default for isoweek, so you can use:
where date >= date_sub(date_trunc(current_date, isoweek, interval 1 week) and
date < date_trunc(current_date, isoweek)
I think it's what you want
where date between DATE_SUB(DATE_TRUNC(CURRENT_DATE(), WEEK(SUNDAY)), interval 6 day) and DATE_TRUNC(CURRENT_DATE(), WEEK(SUNDAY))
You shouldn't use OR in the where statement, it'll cover all the days if you use OR. Instead, you can prefer using AND or between.
I am trying to calculate the number of days of the current of month from day 1 until yesterday without the need of changing the count manually. The original SQL as below:
select order_id
from orders
where date > dateadd(-23 to current_date) and date < 'today'
the desired code is something like
select order_id
from orders
where date > dateadd(datediff(day,firstdayofthemonth,current_date) to current_date) and date < 'today'
Appreciate any help
In firebird you could do:
WHERE
date >= DATEADD(1 - EXTRACT(DAY FROM CURRENT_DATE) DAY TO CURRENT_DATE)
AND date < CURRENT_DATE
In addition to the answer provided by Mark, you can also use BETWEEN (starting with Firebird 2.0.4)
WHERE
date BETWEEN current_date - extract(day from current_date) + 1
AND current_date - 1
P.S. all those answers rely upon DATE data type (thus, date column and CURRENT_DATE variable) having no time part. Which is given for modern SQL dialect 3. But if Dialect 1 would get used it is not given.

In addition to the answer provided by GMB, you can also use fact that Firebird allows addition of days to a date without needing to use dateadd:
date > current_date - extract(day from current_date)
and date < current_date
I am having trouble to find the records which are with in a 30 days range in a given date
Ex: I have record with the date of 10/31/2014 and I have a given specific Due date of 11/28/2014.
I would like to retrieve this record(10/31/2014) when my current date is 10/28/2014 until my current date becomes 11/28/2014 (i.e with in 30 days range). If my current date is 11/29/2014 then I no need retrieve this record.
I have spend almost 3 hours of my time. It will be greatly appreciated if you can give me a query for it.
Thanks,
VJ.
The general format is something to the effect of:
where duedate >= CURRENT_DATE - interval '30' day and duedate <= CURRENT_DATE
This is standard syntax and will work in MySQL and Postgres. An Oracle equivalent is:
where duedate >= trunc(sysdate) - 30 day and duedate <= trunc(sysdate)
And a SQL Server equivalent is:
where duedate >= cast(getdate() - 30 as date) and duedate <= cast(getdate() as date)
I want to get the previous month relative to the current date
SELECT datediff(mm,-1,2-2-2011)
This query gives 67 which is a wrong value .. where i went wrong ?
You can use DATEADD
eg.
SELECT DATEADD(month, -1, GETDATE())
This 2-2-2011 is not a valid date literal - you are subtracting 2 from 2 and then 2011 from the result - proper date literals are '2-2-2011' and #2-2-2011#. You can use GETDATE() to get the current date, instead of relying on a literal.
Nor should you be using DATEDIFF - it gives you the difference between dates.
You should be using DATEADD to calculate new dates.
Try this:
SELECT DATEADD(mm,-1, GETDATE())
This will get the date a month ago.
If you just want the month, you need to also use DATEPART:
SELECT DATEPART(mm, SELECT DATEADD(mm,-1, GETDATE()))
SELECT datepart(mm, dateadd(mm,-1,'2011/1/1') )
If you want the month before the current month, you want
SELECT MONTH(DATEADD(mm, -1, GETDATE()))
If you want the date for a month before the current date, you want
SELECT DATEADD(mm, -1, GETDATE())
BTW, SELECT datediff(mm,-1,2-2-2011) computes the number of months between day -1 and day -2011, which is 67 (2010 / 30). That's nowhere near what you seem to actually want.
You need to use DATEADD - not DATEDIFF
DATEDIFF calculates the difference between two dates - it doesn't add day or months to an existing date....
Also, you need to put your dates into single quotes: use '2-2-2011' instead of simply 2-2-2011.
And lastly: I would strongly recommend using the ISO-8601 date format YYYYMMDD (here: 20110202) - it will work regardless of the language and regional settings on your SQL Server - your date format will BREAK on many servers due to language settings.
DATEDIFF calculates the difference between your stating and ending dates
every date previous to the current date has a positive number and every date next to the current date has negative number, this works in geting your specific date weather it a day,month,year or hour to understand this better below is the syntax of datediff
DATEDIFF (your datetime type, your starting date,your ending date)
the function does (your ending date)-(your starting date)
in your case the below datediff will work just pefectly
SELECT DATEDIFF (month,[you_date_or_datetime_column],GETDATE()) = 1
You can use DATEADD try this code
For previous month
SELECT DATEADD(month, -1, GETDATE())
For 7 day previous
$date = date('Y-m-d',strtotime("-7 days"));
SELECT * FROM users WHERE `date` LIKE '%$date%'
$date varibale get previous date date
