Order one field both ASC and DESC - mysql

I've got a table with events that I'd like to show. I want to sort my events in the future ascending, and the past in descending order. How can I do this with one query?
My current order
Dec 23
Nov 10
Nov 04
Sep 12
Aug 01
Jul 23
The order I want
Nov 4 ** changed place
Nov 10
Dec 23 ** changed place
Sep 12
Aug 01
Jul 23
Many thanks in advance.

You are asking to sort by the distance from current date:
SELECT *
FROM table
ORDER BY IF(date_field >= NOW()),0,1), ABS(DATEDIFF(NOW(), date_field))

MySQL select multiple date range

I have a table with 2 dates: startDate and EndDate
I pass to my query 2 dates and I want to check if in this date range the offer are available.
I have an offer that is valid From 1 may 2019 to 30 may 2019.
When I search in offers, I want to show this only if the date range that I pass is included in the date range of the offer.
OFFER From 1 may 2019 to 30 may 2019
Value pass: 01 jan 2019 to 4 jan 2019 NO SHOW
Value pass: 28 april 2019 to 2 may 2019 NO SHOW
Value pass: 10 may 2019 to 12 may 2019 ONLY SHOW IN THIS CASE
Value pass: 29 may 2019 to 2 june 2019 NO SHOW
Value pass: 10 nov 2019 to 12 now 2019 NO SHOW
How can I do this?
This will work for MySQL.
date_from < '2019-10-05' AND date_to > '2019-10-12'

Sql Server Query not getting desire Result

I want show record month wise and date wise. My query is this but I am not getting how I can achieve this.
Query is
select
iWorkItemId
, convert(varchar(20),Progress.dtProgressDate,106) as dtProgressDate
, vsDescription
, WPD.rWeightage
, Progress.ProgressPerc as ProgressPerc
, Convert(decimal(6,2)
, ((WPD.rWeightage * Progress.ProgressPerc)/100)) as TotalProgress
from tblPkgWorkItems WPD
join tblPkgWorkItemsProgress Progress on WPD.iWorkItemId = Progress.iWorkItemsId
where iPackage='7'
group by iWorkItemId, dtProgressDate,vsDescription,rWeightage,ProgressPerc,progressmonth
order by progressmonth ASC,dtProgressDate ASC , iWorkItemId ASC
Column name : (1) progressmonth (Store Month Name)
(2) dtProgressDate (Store complete date)
Example :
In our table we are storing the records like in this manner:
30 Apr 2013
31 Aug 2013
28 Feb 2013
30 Jan 2013
Then I want to show records like this
30 Jan 2014
if some record is inserted in 15 jan 2014 then After 30 jan 2014 then 15 jan 2014 record will show.
28 Feb 2014
30 Apr 2014
30 Aug 2014
Means firstly Jan records will come then Feb record then March records.
Means all records will come month by order then sort by date wise .
My data is being returned like this:
iWorkItemId dtProgressDate progressmonth rWeightage
320 30 Apr 2014 Apr 2
321 20 Apr 2014 Apr 3
320 10 Feb 2014 Feb 4
321 9 Jan 2014 Jan 7
I want record should come first 9 jan 2014 then 10 Feb 2014 (Means Order by Month) then after it 30 April 2014, then 20 april 2014 (Then Sot by Date).
iWorkItemId will repeat win every month.
For my problem is I want to show
Firstly Jan records then Feb records , then March records
And whenever Jan month is coming then All Date which is belong to jan month that will come under JAN month.
Firstly Higher date of JAN month (Means ) 31 Jan 2014, 30 jan 2014, 29 jan 2014, 28 feb 2014, then 27 feb 2014.
Means first records fetch month wise then on particular month that records sort by datewise

MS Access year to date numbers by month

I have a query in an Access database which returns the results below:
MthName 2010
Jan £4.51
Feb £10.20
Mar £17.51
Apr £22.86
May £28.82
Jun £33.30
Jul £37.96
Aug £42.52
Sep £47.88
Oct £54.25
Nov £60.52
Dec £65.80
That is fine but these are year to date numbers and I would like to create a query that could give me the actual month numbers instead.
Taking the above sample the Jan number is clearly £4.51 but the Feb number is
(£10.2-£4.51)= £5.70
I have tried using something like DLOOKUP but it seems that would be really slow and wasn't working correctly.
This can be achieved very easily in Excel but I was hoping to find a query for future use.
Thanks
Avoid using Dlookup as much as you can.
if it is possible to add column [mntNum] with SEQUENCE number of month :
mtnNum MthName 2010
01 Jan £4.51
02 Feb £10.20
03 Mar £17.51
04 Apr £22.86
05 May £28.82
06 Jun £33.30
07 Jul £37.96
08 Aug £42.52
09 Sep £47.88
10 Oct £54.25
11 Nov £60.52
12 Dec £65.80
Query
SELECT table.mntNum, table.mntName, table.[2010], [2010]-nz((SELECT [prev].[2010] FROM [table] as [prev] where [prev].[mntNum]=[table].[mntNum]-1),0) AS JUST_THIS_MONTH
FROM [table];
UPD:
Result of this query
mntNum mntName 2010 JUST_THIS_MONTH
1 Jan 4.51 4.51
2 Feb 10.2 5.69
3 Mar 17.51 7.31
4 apr 22.86 5.35
5 may 28.82 5.96
6 jun 33.3 4.48
7 jul 37.96 4.66
8 Aug 42.52 4.56
9 Sep 47.88 5.36
10 Oct 54.25 6.37
11 Nov 60.52 6.27
12 Dec 65.8 5.27999999999999

Getting data between two date strings in MySQL

I have been recording Twitter data for a project I'm working on the date information is saved as Thu, 14 Jul 2011 06:21:48 +0000 in a string field.
How do I select data that falls between two dated using mySQL? I can get data larger than a value or smaller than a value but not between to values.
The data for example is:
Thu, 14 Jul 2011 06:21:48 +0000
Thu, 14 Jul 2011 12:18:21 +0000
Thu, 14 Jul 2011 18:48:00 +0000
Thu, 14 Jul 2011 23:48:02 +0000
Fri, 15 Jul 2011 06:48:10 +0000
Fri, 15 Jul 2011 12:48:00 +0000
Fri, 15 Jul 2011 18:43:32 +0000
Fri, 15 Jul 2011 23:44:08 +0000
Sat, 16 Jul 2011 06:47:08 +0000
Sat, 16 Jul 2011 12:46:49 +0000
Sat, 16 Jul 2011 18:45:41 +0000
Sat, 16 Jul 2011 23:41:27 +0000
My SQL string is:
SELECT *
FROM twitter
WHERE SUBSTR(twitter_date, 6, 11) >= '2011-06-15'
AND SUBSTR(twitter_date, 6, 11) <= '2011-06-21'
I've tried BETWEEN statements as well but no luck.
Any help will be appreciated!
You can't use between because they are strings and not actual date fields. If you know the format of the date will always be the same, you can do the following:
STR_TO_DATE(str,format)
SELECT *
FROM twitter
WHERE STR_TO_DATE(twitter_date, '%a, %c %b %Y %k:%i:%s')
between '2011-06-15' AND '2011-06-21'
You are comparing "6 Jul 2011" with 2011-06-15.
It should be
SELECT *
FROM twitter
WHERE SUBSTR(twitter_date, 6, 11) >= '6 Jul 2011'
AND SUBSTR(twitter_date, 6, 11) <= '21 Jul 2011'
You may want to look into MySQLs STR_TO_DATE function. This will give you a date and between should work as expected.
The query will fail. You're comparing two STRINGS, not dates. You need to tell MySQL explicitly that you want to treat the strings as dates. Since it's date information, store it in a date or datetime field type in MySQL, which saves you all this trouble:
SELECT STR_TO_DATE(SUBSTR(twitter_date, 6, 11)) >= '2011-06-15' ...
Forcing your left-hand-side to be a proper date value will hint to MySQL that it should treat the right-hand-side as a date as well.
Once you have altered your table to hold the date data in proper DATETIME fields, you may want to refer to my answer to the following question regarding dates and filtering them, which may prove useful.
For example, in your query / data above, what would happen if you had no data for one of the dates you were querying? You'd get no output for that date, which may look odd when charting, etc. If you use the technique I describe in the attached question, you can get that additional information, and other useful stuff like the day of the week, month name, etc.
Select all months within given date span, including the ones with 0 values
Hope that helps!
