I have a table with columns
Account number (number)
Account Status(Number)
Datetime(text)
some accounts are repeating with same time stamp
I need to get the account status of repeating data of the same account with same timestamp to same row as new column (new Account Status)
Account_Number Account Status Timestamp
7856277 5 9155070519
4527882 5 1045225522
7856277 1 9155070519
I want to
Account_Number Account Status Timestamp new account Status
7856277 5 9155070519 1
You will want to join the table with itself, using the account number as the linked column. Consider the query below (where o is the older record and n is the newer one)
SELECT o.account_number, o.account_status, n.timestamp, n.account_status "new account status"
FROM table o join table n on (o.account_number = n.account_number)
WHERE n.timestamp>o.timestamp
SQL tables represent unordered sets. So, there is no "new" or "old" unless a column specifies the ordering. You don't seem to have such a column.
But you can use aggregation to get the results on a single row:
select Account_Number, Timestamp,
min(AccountStatus) as status_min,
max(AccountStatus) as status_max
from t
group by Account_Number, Timestamp
having count(*) > 1;
You need a self join:
SELECT
t.account_number, t.account_status, t.timestamp,
tt.account_status new_account_status
FROM tablename t INNER JOIN tablename tt
ON
tt.account_number = t.account_number AND
tt.timestamp = t.timestamp AND
tt.account_status < t.account_status

I have run into an issue I don't know how to solve. I'm working with a MS Access DB.
I have this data:
I want to write a SELECT statement, that gives the following result:
For each combination of Project and Invoice, I want to return the record containing the maximum date, conditional on all records for that combination of Project and Invoice being Signed (i.e. Signed or Date column not empty).
In my head, first I would sort the irrelevant records out, and then return the max date for the remaining records. I'm stuck on the first part.
Could anyone point me in the right direction?
Thanks,
Hulu
Start with an initial query which fetches the combinations of Project, Invoice, Date from the rows you want returned by your final query.
SELECT
y0.Project,
y0.Invoice,
Max(y0.Date) AS MaxOfDate
FROM YourTable AS y0
GROUP BY y0.Project, y0.Invoice
HAVING Sum(IIf(y0.Signed Is Null,1,0))=0;
The HAVING clause discards any Project/Invoice groups which include a row with a Null in the Signed column.
If you save that query as qryTargetRows, you can then join it back to your original table to select the matching rows.
SELECT
y1.Project,
y1.Invoice,
y1.Desc,
y1.Value,
y1.Signed,
y1.Date
FROM
YourTable AS y1
INNER JOIN qryTargetRows AS sub
ON (y1.Project = sub.Project)
AND (y1.Invoice = sub.Invoice)
AND (y1.Date = sub.MaxOfDate);
Or you can do it without the saved query by directly including its SQL as a subquery.
SELECT
y1.Project,
y1.Invoice,
y1.Desc,
y1.Value,
y1.Signed,
y1.Date
FROM
YourTable AS y1
INNER JOIN
(
SELECT y0.Project, y0.Invoice, Max(y0.Date) AS MaxOfDate
FROM YourTable AS y0
GROUP BY y0.Project, y0.Invoice
HAVING Sum(IIf(y0.Signed Is Null,1,0))=0
) AS sub
ON (y1.Project = sub.Project)
AND (y1.Invoice = sub.Invoice)
AND (y1.Date = sub.MaxOfDate);
Write A SQL query, which should be possible in MS-Access too, like this:
SELECT
Project,
Invoice,
MIN([Desc]) Descriptions,
SUM(Value) Value,
MIN(Signed) Signed,
MAX([Date]) "Date"
FROM data
WHERE Signed<>'' AND [Date]<>''
GROUP BY
Project,
Invoice
output:
Project
Invoice
Descriptions
Value
Signed
Date

Note: for invoice 1 on project A, you will see a value of 300, which is the total for that invoice (when grouping on Project='A' and Invoice=1).
Maybe I should have used DCONCAT (see: Concatenation in between records in Access Query ) for the Description, to include 'TV' in it. But I am unable to test that so I am only referring to this answer.
Try joining a second query:
Select *
From YourTable As T
Inner Join
(Select Project, Invoice, Max([Date]) As MaxDate
From YourTable
Group By Project, Invoice) As S
On T.Project = S.Project And T.Invoice = S.Invoice And T.Date = S.MaxDate
I have a table with the follow structure
ID ReportDate Object_id
What I need to know, is the count of new and count of old (Object id's)
For example: If I have the data below:
I want the following output grouped by ReportDate:
I thought a way doing it using a Where clause based on date, however i need the data for all the dates I have in the table. To see the count of what already existed in the previous report and what is new at that report. Any Ideas?
Edit: New/Old definition- New would be the records that never appeared before that report run date and appeared on this one, whereas old is the number of records that had at least one match in previous dates. I'll edit the post to include this info.
managed to do it using a left join. Below is my solution in case it helps anyone in the future :)
SELECT table.ReportRunDate,
-1*sum(table.ReportRunDate = new_table.init_date) as count_new,
-1*sum(table.ReportRunDate <> new_table.init_date) as count_old,
count(*) as count_total
FROM table LEFT JOIN
((SELECT Object_ID, min(ReportRunDate) as init_date
FROM table
GROUP By OBJECT_ID) as new_table)
ON table.Object_ID = new_table.Object_ID
GROUP BY ReportRunDate
This would work in Oracle, not sure about ms-access:
SELECT ReportDate
,COUNT(CASE WHEN rnk = 1 THEN 1 ELSE NULL END) count_of_new
,COUNT(CASE WHEN rnk <> 1 THEN 1 ELSE NULL END)count_of_old
FROM (SELECT ID
,ReportDate
,Object_id
,RANK() OVER (PARTITION BY Object_id ORDER BY ReportDate) rnk
FROM table_name)
GROUP BY ReportDate
Inner query should rank each occurence of object_id based on the ReportDate so the 1st occurrence of certain object_id will have rank = 1, the next one rank = 2 etc.
Then the outer query counts how many records with rank equal/not equal 1 are the within each group.
I assumed that 1 object_id can appear only once within each reportDate.
I'm working in a telecom and part of work is to check the last status for a specific mobile number along with that last de-active status,it's easy to get the active number by using the condition ACTIVE int the statement ,but it's not easy to pick the last de-active status because each number might have more than one de-active status or only one status ACTIVE, I use the EXP_DATE as an indicator for the last de-active status,I want to show both new data and old data in one row,but I'm struggling with that ,below my table and my expected result :-
my expected result
query that I use on daily basis
select * from test where exp_date>sysdate; to get the active numbers , to get the de-active number select * from test where exp_date<sysdate;
You just need to do outer join with one subquery containing ACTIVE records and one with latest DE-ACTIVE record as following:
SELECT A.MSISDN,
A.NAME,
A.SUB_STATUS,
A.CREATED_DATE,
A.EXP_DATE,
D.MSISDN AS MSISDN_,
D.NAME AS OLD_NAME,
D.SUB_STATUS OLD_STATUS,
D.CREATED_DATE AS OLD_CREATED_DATE,
D.EXP_DATE AS OLD_EXP_DATE
FROM
(SELECT * FROM TEST
WHERE EXP_DATE > SYSDATE
AND SUB_STATUS = 'ACTIVE') A -- ACTIVE RECORD
-- USE CONDITION TO FETCH ACTIVE RECORD AS PER YOUR REQUIREMENT
FULL OUTER JOIN
(SELECT * FROM
(SELECT T.*,
ROW_NUMBER() OVER (PARTITION BY T.MSISDN ORDER BY EXP_DATE DESC NULLS LAST) AS RN
FROM TEST T
WHERE T.EXP_DATE < SYSDATE
AND T.SUB_STATUS='DE-ACTIVE')
-- USE CONDITION TO FETCH DEACTIVE RECORD AS PER YOUR REQUIREMENT
WHERE RN = 1
) D
ON (A.MSISDN = D.MSISDN)
Cheers!!
Here is an overview of how to do this -- one query to get a distinct list of all the phone numbers, left join to a list of the most recent active on that phone number,left join to a list of the most recent de-active on the phone number
How about conditional aggregation?
select msidn,
max(case when status = 'DE-ACTIVE' then create_date end) as deactive_date,
max(case when status = 'ACTIVE' then exp_date end) as active_date
from test
group by msisdn
I generated a query to pull in unique logins by date, and the average duration of each. What I am now trying to do is add a column representing the logins.
The way I'm pulling in the unique logins is by subtracting the maximum and minimum created date (as this is needed to calculate average duration).
I now have a simple query to calculate all logins (not simply unique logins).
Based on my query - how can I add a column so I will have logins, unique logins, average_duration, and the login_date?
MY QUERY:
SELECT
COUNT(unique_session_ids) as unique_logins
,AVG(
CASE WHEN duration > '0'
THEN duration
END) as average_duration
,login_date
FROM(
SELECT a.session_id as unique_session_ids
,MAX(a.created)-min(a.created) as duration
,MIN(to_char(b.created,'mm-dd')) as login_date
FROM base_identity a
INNER JOIN base_identity b
ON a.session_id = b.session_id
WHERE a.source_system_id = 11
AND a.created >= '2018-12-01'
GROUP BY a.session_id) x
GROUP BY login_date;
WHAT I WANT TO ADD TO THAT:
SELECT COUNT(session_id) as logins
FROM base_identity
GROUP BY to_char(created,'mm-dd')
So, I essentially just want the logins and unique logins represented together.
Thanks!
You can select from multiple tables with the following syntax
SELECT Table1.column_name, Table2.column_name
FROM Table1, Table2
In your case, it would look like
SELECT
COUNT(x.unique_session_ids) as unique_logins
,AVG(CASE WHEN x.duration > '0' THEN x.duration END) as average_duration
,x.login_date
,COUNT(y.session_id)
FROM([...]) x
, base_identity y
GROUP BY x.login_date;
I am using Terdata SQL Assistant connected to an enterprise DW. I have written the query below to show an inventory of outstanding items as of a specific point in time. The table referenced loads and stores new records as changes are made to their state by load date (and does not delete historical records). The output of my query is 1 row for the specified date. Can I create a stored procedure or recursive query of some sort to build a history of these summary rows (with 1 new row per day)? I have not used such functions in the past; links to pertinent previously answered questions or suggestions on how I could get on the right track in researching other possible solutions are totally fine if applicable; just trying to bridge this gap in my knowledge.
SELECT
'2017-10-02' as Dt
,COUNT(DISTINCT A.RECORD_NBR) as Pending_Records
,SUM(A.PAY_AMT) AS Total_Pending_Payments
FROM DB.RECORD_HISTORY A
INNER JOIN
(SELECT MAX(LOAD_DT) AS LOAD_DT
,RECORD_NBR
FROM DB.RECORD_HISTORY
WHERE LOAD_DT <= '2017-10-02'
GROUP BY RECORD_NBR
) B
ON A.RECORD_NBR = B.RECORD_NBR
AND A.LOAD_DT = B.LOAD_DT
WHERE
A.RECORD_ORDER =1 AND Final_DT Is Null
GROUP BY Dt
ORDER BY 1 desc
Here is my interpretation of your query:
For the most recent load_dt (up until 2017-10-02) for record_order #1,
return
1) the number of different pending records
2) the total amount of pending payments
Is this correct? If you're looking for this info, but one row for each "Load_Dt", you just need to remove that INNER JOIN:
SELECT
load_Dt,
COUNT(DISTINCT record_nbr) AS Pending_Records,
SUM(pay_amt) AS Total_Pending_Payments
FROM DB.record_history
WHERE record_order = 1
AND final_Dt IS NULL
GROUP BY load_Dt
ORDER BY 1 DESC
If you want to get the summary info per record_order, just add record_order as a grouping column:
SELECT
load_Dt,
record_order,
COUNT(DISTINCT record_nbr) AS Pending_Records,
SUM(pay_amt) AS Total_Pending_Payments
FROM DB.record_history
WHERE final_Dt IS NULL
GROUP BY load_Dt, record_order
ORDER BY 1,2 DESC
If you want to get one row per day (if there are calendar days with no corresponding "load_dt" days), then you can SELECT from the sys_calendar.calendar view and LEFT JOIN the query above on the "load_dt" field:
SELECT cal.calendar_date, src.Pending_Records, src.Total_Pending_Payments
FROM sys_calendar.calendar cal
LEFT JOIN (
SELECT
load_Dt,
COUNT(DISTINCT record_nbr) AS Pending_Records,
SUM(pay_amt) AS Total_Pending_Payments
FROM DB.record_history
WHERE record_order = 1
AND final_Dt IS NULL
GROUP BY load_Dt
) src ON cal.calendar_date = src.load_Dt
WHERE cal.calendar_date BETWEEN <start_date> AND <end_date>
ORDER BY 1 DESC
I don't have access to a TD system, so you may get syntax errors. Let me know if that works or you're looking for something else.
