IN Clause issue - sql

I have one SQL output table like this
ITEM,LOC,PERIOD,QUANTITY
101,US,07/22/2015,500
101,US,07/02/2015,0
102,LON,07/22/2015,0
102,LON,07/02/2015,1000
But I want the output table as follows,
ITEM LOC 07/22/2015 07/02/2015
101 US 500 0
102 LON 0 1000
Please find the code which I have used below,
select * from
(
select item, loc, period, quantity
from example
)
pivot
(
sum (quantity) for period in ('22/JUL/2015','02/JUL/2015'));
If it is for 2 dates, then no issue in mentionning the 'IN' clause
If it is 1000 dates like weekly, monthly and daily. Then how ?
Below command is not working in 'IN' clause.
SELECT PERIOD FROM EXAMPLE WHERE PERIOD < TO_DATE(22/JUL/2015);
Can you please help me to solve this issue ?
Thanks for your time.

Your issue may be incompatible data types. If the period column on your table is DATE type, you are trying to compare strings/VARCHAR with DATE type.
If period column is a DATE try changing your IN to
SELECT period FROM example WHERE period < DATE '2015-07-22';
or
SELECT period FROM example WHERE period < TO_DATE('22/JUL/2015', 'DD/MON/YYYY');

SQL minimum date value after today's date Now()

I am writing a query and am having trouble filtering data as I would like. In the table, there is a date field and an ItemCode field. I would like to return one record per ItemCode with the earliest date that is after today.
If today is 6/6/2017 and my data looks like:
ItemCode Date
1 6/1/2017
1 6/7/2017
1 6/10/2017
2 6/2/2017
2 6/8/2017
2 6/15/2017
I would want the result to be
ItemCode Date
1 6/7/2017
2 6/8/2017
My query so far is:
SELECT PO_PurchaseOrderDetail.ItemCode, Min(PO_PurchaseOrderDetail.RequiredDate) AS NextPO
FROM PO_PurchaseOrderDetail
GROUP BY PO_PurchaseOrderDetail.ItemCode
HAVING (((Min(PO_PurchaseOrderDetail.RequiredDate))>=Now()));
The problem is that the Min function fires first and grabs the earliest dates per ItemCode, which are before today. Then the >=Now() is evaluated and because the min dates are before today, the query returns nothing.
I've tried putting the >=Now() inside the min function in the HAVING part of the query but it does not change the result.
My structure is wrong and I would appreciate any advice. Thanks!
I would approach like this for standard SQL, Access approach may vary
select PO_PurchaseOrderDetail.ItemCode,
min(PO_PurchaseOrderDetail.RequiredDate) as NextPO
from PO_PurchaseOrderDetail
where PO_PurchaseOrderDetail.RequiredDate >= Now()
group by PO_PurchaseOrderDetail.ItemCode;
Put the date condition in the where clause (not the having clause):
select ItemCode, min(Date) as NextPO
from PO_PurchaseOrderDetail
where Date > '6/6/2017'
group by ItemCode

Select Query between dates not retrieving any data

I have been trying to retrieve the rows registered between two dates (since every time a person goes through a door a row is inserted). This way we get the "amount of visitors" on a monthly basis.
When querying the following:
select MOV_DATAHORA from LOG_CREDENCIAL
WHERE MOV_DATAHORA>'2017-01-01'`
a total of 5851 rows are shown. This is an example of a row:
2017-01-05 21:33:30.000
However when trying the following:
select MOV_DATAHORA from LOG_CREDENCIAL
WHERE MOV_DATAHORA>'2017-01-01'
AND MOV_DATAHORA<'2017-01-02'
0 rows are shown. I even tried the count(MOV_DATAHORA) statement but it still isn't working. I also tried with the BETWEEN statement unsuccessfully. Any ideas why?
Well... the simplest explanation based on your query predicate:
WHERE MOV_DATAHORA > '2017-01-01'
AND MOV_DATAHORA < '2017-01-02'
is that on January 1st (right after the New years) there were no visitors.
You are comparing a DateTime and a Date data types. Your table has a DateTime as you can see the 21:33:30.000 after the date, to convert and compare like types do the following.
SELECT MOV_DATAHORA FROM LOG_CREDENCIAL WHERE DATE(MOV_DATAHORA)>'2017-01-01'
AND DATE(MOV_DATAHORA)<'2017-01-02'
or using between
SELECT MOV_DATAHORA FROM LOG_CREDENCIAL WHERE DATE(MOV_DATAHORA) BETWEEN '2017-01-01'
AND '2017-01-02'

SQL: select datetime values prior to that date based on it's value

I want to select rows for a field MRD which is declared as date where it is prior for that date only.
So
(case when sum (transPoints) > 4 and MRD is that same date then 4
So if a row has a date of today, I want the case when to be triggered when the transaction points are bigger than 4 against all columns with the same date.
As you can imagine the date field will be different against many rows.
Based on what I can understand from your question, it seems that the GROUP BY clause may be what you're looking for. If your date column is in the correct format then you may have to use something like:
SELECT CAST(DateColumn as DATE)
FROM YourTable
GROUP BY CAST(DateColumn as DATE)

Get Months between two Date columns

I have a table AreaValues with columns ID, Name, Value, startDate, EndDate.
I need to view a report that select the values of every month with month name or number
Example: this is my table AreaValues:
ID Name Value StartDate EndDate
-------------------------------------------
1 Test 200 05-06-2012 07-08-2016
I need report get the value using SQL Server Reporting Services or query or any way:
month value = (200 / count of months from startdate to end date)
ID Name Value year2012 year2013 year2014 year2015 year2016
1 test 200 6,7,8,9,10,11,12 1,2,3,....12 1,2,3,....12 1,2,3,....12 1,2,3,4,5,6,7
and do that for every record in the table
Please, I need help
It Solved
I used a Loop in SQl that get all months between two dates
Then
Create report with Matrix get the months above and ID left

issue with complex query involving returning 0 for no data in query result

I have a table defined in Oracle11g schema like this
Txn_summ_dec
=================
id
currentdate
resource_id
user_id
trans_id
eventdescptn
each resource has different event descriptions.
I give a date range (of maximum 1 month or less) and resource_id and I want to get distinct count of all users for the given resource id, group by currentdate, eventdescptn
So I have the following query
SELECT COUNT(DISTINCT(txn_summ_dec.user_id)) as dusers, currentDate, eventdescptn
FROM Txn_summ_dec
WHERE resource_id = 1
AND currentdate BETWEEN TO_DATE('2011-12-01', 'YYYY-MM-DD')
AND TO_DATE('2011-12-31', 'YYYY-MM-DD')
GROUP BY currentdate, eventdescptn
and it gives me rightly the result below
dusers currentdate eventdescptn
182 12/01/2011 00:00:00 Save
33 12/04/2011 00:00:00 Save
98 12/01/2011 00:00:00 Read
22 12/30/2011 00:00:00 Write
I want result in the following format: From the query
with the given date range is suppose 5th to 5th of a month (or less) I want results for all dates in the range for all eventdescptn of a resource. If there is no result for a particular date in the range, for a particular event descptn then it should still have that record in the resultset with a 'dusers' value = 0
so if a resource has 3 different eventdescptns (Save, Read, Write) and the date range is 5th to 30th of a month then there should be a total of 26X3 = 78 records in the resultset..
How do I write a query for that?
Also I will need to convert it to hibernate later.. but Sql to start with is fine
Thanks in advance
Check the accepted answer here:
generate days from date range
If I understand you correctly you don't necessarily have an event for every date in the range in your log. That answer gives you a way to materialize a list of dates in the range. If you can modify it to include 1 of each of those dates per event, you would just have to join back to the results you have already aggregated here and set the null dUsers to zero.
I haven't tried this, but I wonder if you could you do:
WITH the_query AS (
... your query here ...
)
SELECT dusers, currentdate, eventdescptn
FROM the_query
WHERE 0 != ( SELECT COUNT(*) FROM the_query )
UNION
SELECT 0, NULL, NULL
FROM the_query
WHERE 0 = ( SELECT COUNT(*) FROM the_query )
