Access SQL - consolidated SUM - sql

I have a table of several hundred thousand similar records and I am trying to consolidate multiple similar records into a more concise table. The SQL query I have used below doesn't give me accurate results when compared with the original table, but I am not sure why.
The table is intended to pull all fields from the original table but consolidate each record in to a single unique record with a sum of the count, so the sum of count should correspond exactly with the sum from the original table.
SELECT Date_mday, date_month, date_year, [Message#EventID], aaRequestType,
[Message#SecurityParameters#AccountNumber] ,
[Message#SecurityParameters#LogonUserID] ,
InstitutionPOBoxCountry,
[Message#SecurityParameters#RoleData] ,
Sum(Count) AS SumOfCount
FROM TempImport
GROUP BY Date_mday, date_month, date_year, [Message#EventID], aaRequestType, [Message#SecurityParameters#AccountNumber], [Message#SecurityParameters#LogonUserID], InstitutionPOBoxCountry, [Message#SecurityParameters#RoleData], Count;
I'm certain that this is straightforward to solve but I have tried a few different approaches and am pretty stumped.
My original table looks like this:
date_mday | date_month | date_year | Message#EventID | aaRequestType | Message#SecurityParameters#AccountNumber | Message#SecurityParameters#LogonUserID | InstitutionPOBoxCountry | Message#SecurityParameters#RoleData | count
-----------|------------|-----------|-----------------|---------------|------------------------------------------|----------------------------------------|-------------------------|-------------------------------------|-------
1 | Jan | 2017 | XML-INPUT | GetData | A1234 | AAA1234 | GB | VALIDATE | 1
1 | Jan | 2017 | XML-INPUT | GetData | A1234 | AAA1234 | GB | VALIDATE | 1
1 | Jan | 2017 | XML-INPUT | GetData | A1234 | AAA1234 | GB | VALIDATE | 1
1 | Jan | 2017 | XML-INPUT | GetData | A1234 | AAA1234 | GB | VALIDATE | 1
And the consolidated table would have a single line, but with the final column (SumOfCount) as 4.

count is the field you are aggregating. If you include it in the GROUP BY, you will get a separate row for each count value.
Because you want to sum the values:
SELECT Date_mday, date_month, date_year, [Message#EventID], aaRequestType,
[Message#SecurityParameters#AccountNumber],[Message#SecurityParameters#LogonUserID] ,
InstitutionPOBoxCountry, [Message#SecurityParameters#RoleData] ,
Sum(Count) AS SumOfCount
FROM TempImport
GROUP BY Date_mday, date_month, date_year, [Message#EventID], aaRequestType, [Message#SecurityParameters#AccountNumber],
[Message#SecurityParameters#LogonUserID], InstitutionPOBoxCountry, [Message#SecurityParameters#RoleData];
Your GROUP BY should only contain columns that are not part of aggregation functions.

How to find two consecutive rows sorted by date, containing a specific value?

I have a table with the following structure and data in it:
| ID | Date | Result |
|---- |------------ |-------- |
| 1 | 30/04/2020 | + |
| 1 | 01/05/2020 | - |
| 1 | 05/05/2020 | - |
| 2 | 03/05/2020 | - |
| 2 | 04/05/2020 | + |
| 2 | 05/05/2020 | - |
| 2 | 06/05/2020 | - |
| 3 | 01/05/2020 | - |
| 3 | 02/05/2020 | - |
| 3 | 03/05/2020 | - |
| 3 | 04/05/2020 | - |
I'm trying to write an SQL query (I'm using SQL Server) which returns the date of the first two consecutive negative results for a given ID.
For example, for ID no. 1, the first two consecutive negative results are on 01/05 and 05/05.
The first two consecutive results for ID No. 2 are on 05/05 and 06/05.
The first two consecutive negative results for ID No. 3 are on on 01/05 and 02/05 .
So the query should produce the following result:
| ID | FirstNegativeDate |
|---- |------------------- |
| 1 | 01/05 |
| 2 | 05/05 |
| 3 | 01/05 |
Please note that the dates aren't necessarily one day apart. Sometimes, two consecutive negative tests may be several days apart. But they should still be considered as "consecutive negative tests". In other words, two negative tests are not 'consecutive' only if there is a positive test result in between them.
How can this be done in SQL? I've done some reading and it looks like maybe the PARTITION BY statement is required but I'm not sure how it works.
This is a gaps-and-island problem, where you want the start of the first island of '-'s that contains at least two rows.
I would recommend lead() and aggregation:
select id, min(date) first_negative_date
from (
select t.*, lead(result) over(partition by id order by date) lead_result
from mytable t
) t
where result = '-' and lead_result = '-'
group by id
Use LEAD or LAG functions over ID partition ordered by your Date column.
Then simple check where LEAD/LAG column is equal to Result.
You'll need also to filter the top ones.
The image attached just shows what LEAD/LAG would return

Query columns based on values of table

I'm new to DB and SQL so I don't know if there is anything new I need to try for this. I want to solve this table my senior has given to me:
Passbook(Table Name)
Date | Amount | Type
-----------------------------
14/3/19 | 48000 | Debit |
13/2/19 | 75000 | Credit|
9/7/19 | 65000 | Credit|
12/6/19 | 15000 | Debit |
Now I have to generate a query in this manner:
Month | Debit | Credit
------------------------------
13/2/19 | 0 | 75000
14/3/19 | 48000 | 0
12/6/19 | 15000 | 0
9/7/19 | 0 | 65000
Here my Passbook table value has become the columns for query and IDK how to generate it in this manner
Anyone help me do this please
for monthly sorting, I'm supposed to use ORDER BY clause, I suppose
Now I have to generate a query in that manner.
A basic pivot query should work here:
SELECT
Format(Month([Date])) AS Month,
SUM(IIF(Type = 'Debit', Amount, 0)) AS Debit,
SUM(IIF(Type = 'Credit', Amount, 0)) AS Credit
FROM yourTable
GROUP BY
Format(Month([Date]));
If you instead want date level output, then aggregate the by the Date column directly.

Access 2016 & SQL: Totaling two columns, then subtracting them

Say I have a MoneyIN and a MoneyOUT column. I wish to total these entire columns up so I have a sum of each, then I wish to subtract the total of the MoneyOUT column from the total of the MoneyIN column. I also want to display a DateOF column and possibly a description (I think I can do that by myself).
This would be the original database where I get my information from:
+-------------+------------------+---------+----------+-----------+
| Location ID | Location Address | Date Of | Money In | Money Out |
+-------------+------------------+---------+----------+-----------+
| 1 | blah | date | 10.00 | 0.00 |
| 2 | blah | date | 2,027.10 | 27.10 |
| 2 | blah | date | 0.00 | 2000.00 |
| 1 | blah | date | 0.00 | 10.00 |
| 3 | blah | date | 5000.00 | 0.00 |
+-------------+------------------+---------+----------+-----------+
I would like to be able to type in a location ID and then have results show up (in this example I type 2 for the location)
+---------+----------+-----------+------+
| Date Of | Money In | Money Out | |
+---------+----------+-----------+------+
| date | 2027.10 | 27.10 | |
| date | 0 | 2000 | |
| Total: | 2027.10 | 2027.10 | 0 |
+---------+----------+-----------+------+
I have tried other solutions (One of which was pointed out below), however, they don't show the sum of each entire column, they simply subtract MoneyOUT from MoneyIN for each row. As of now, I am trying to do this in a query, but if there is a better way, please elaborate.
I am extremely new to SQL and Access, so please make the explanation understandable for a beginner like me. Thanks so much!
This is a table referred to below.
+-------------+-------+----------+-----------+-----------+
| Location ID | Date | Money IN | Money Out | Total Sum |
+-------------+-------+----------+-----------+-----------+
| 1 | date | 300 | 200 | |
| 1 | date | 300 | 200 | |
| 1 | date | 300 | 200 | |
| 1 | total | 900 | 600 | 300 |
+-------------+-------+----------+-----------+-----------+
The following should give you what you want:
SELECT DateOf, MoneyIn, MoneyOut, '' AS TotalSum FROM YourTable
UNION
SELECT 'Total', SUM(MoneyIn) AS SumIn, SUM(MoneyOut) AS SumOut,
SUM(MoneyIn - MoneyOut) AS TotalSum FROM YourTable
Edit:
You do not need to alter very much to achieve what you want. In order to get Access to prompt for a parameter when running a query, you give a name for the parameter in square brackets; Access will then pop-up a window prompting the user for this value. Also this parameter can be used more than once in the query, without Access prompting for it multiple times. So the following should work for you:
SELECT DateOf, MoneyIn, MoneyOut, '' AS TotalSum
FROM YourTable
WHERE LocationID=[Location ID]
UNION
SELECT 'Total', SUM(MoneyIn) AS SumIn, SUM(MoneyOut) AS SumOut,
SUM(MoneyIn - MoneyOut) AS TotalSum FROM YourTable
WHERE LocationID=[Location ID];
However, looking at your table design, I strongly encourage you to change it. You are including the address on every record. If you have three locations, but 100 records, then on average you are unnecessarily repeating each address more than 30 times. The "normal" way to avoid this would be to have a second table, Locations, which would have an ID and an Address field. You then remove address from YourTable, and in its place create a one-to-many relationship between the ID in Locations and the LocationID in YourTable.
It's a little unclear exactly what you expect without sample data, but I think this is what you want:
SELECT DateOf, SUM(MoneyIN) - SUM(MoneyOut)
FROM YourTable
GROUP BY DateOf
This will subtract the summed total of MoneyOut from MoneyIn at each distinct DateOf
Updated Answer
A UNION will let you append a 'Totals' record to the bottom of your result set:
SELECT *
FROM (
SELECT CAST(DateOf as varchar(20)) as DateOf, MoneyIn, MoneyOut, '' as NetMoneyIn
FROM YourTable
UNION
SELECT 'Total:', SUM(MoneyIn), SUM(MoneyOut), SUM(MoneyIN) - SUM(MoneyOut)
FROM YourTable
) A
ORDER BY CASE WHEN DateOf <> 'Total:' THEN 0 ELSE 1 END, DateOf
Some notes.. I used a derived table to ensure that the 'Total' record is last. Also casted DateOf to a string (assuming it is a date), otherwise you will have issues writing the string 'Total:' to that column.

SQL sum 12 weeks of data based on first sold date across different items

The database has thousands of individual items, each with multiple first sold dates and sales results by week. I need a total sum for each products first 12 weeks of sales.
Code was used for previous individual queries when we know the start date using a SUM(CASE. This is too manual though with thousands of products to review and we are looking for a smart way to speed this up.
Can I build on this so the sum find the minimum first shop date, and then sums the next 12 weeks of results? If so, how do I structure it, or is there a better way?
Columns in database I will need to reference with sample data
PROD_ID | WEEK_ID | STORE_ID | FIRST_SHOP_DATE | ITM_VALUE
12345543 | 201607 | 10000001 | 201542 | 24,356
12345543 | 201607 | 10000002 | 201544 | 27,356
12345543 | 201608 | 10000001 | 201542 | 24,356
12345543 | 201608 | 10000002 | 201544 | 27,356
32655644 | 201607 | 10000001 | 201412 | 103,245
32655644 | 201607 | 10000002 | 201420 | 123,458
32655644 | 201608 | 10000001 | 201412 | 154,867
32655644 | 201608 | 10000002 | 201420 | 127,865
You can do something like this:
select itemid, sum(sales)
from (select t.*, min(shopdate) over (partition by itemid) as first_shopdate
from t
) t
where shopdate < first_stopdate + interval '84' day
group by id;
You don't specify the database, so this uses ANSI standard syntax. The date operations (in particular) vary by database.
Hi Kirsty, Try like this -
select a.Item,sum(sales) as totla
from tableName a JOIN
(select Item, min(FirstSoldDate) as FirstSoldDate from tableName group by item) b
ON a.Item = b.Item
where a.FirstSoldDate between b.FirstSoldDate and (dateadd(day,84,b.FirstSoldDate))
group by a.Item
Thanks :)

SQL deleting rows with duplicate dates conditional upon values in two columns

I have data on approx 1000 individuals, where each individual can have multiple rows, with multiple dates and where the columns indicate the program admitted to and a code number.
I need each row to contain a distinct date, so I need to delete the rows of duplicate dates from my table. Where there are multiple rows with the same date, I need to keep the row that has the lowest code number. In the case of more than one row having both the same date and the same lowest code, then I need to keep the row that also has been in program (prog) B. For example;
| ID | DATE | CODE | PROG|
--------------------------------
| 1 | 1996-08-16 | 24 | A |
| 1 | 1997-06-02 | 123 | A |
| 1 | 1997-06-02 | 123 | B |
| 1 | 1997-06-02 | 211 | B |
| 1 | 1997-08-19 | 67 | A |
| 1 | 1997-08-19 | 23 | A |
So my desired output would look like this;
| ID | DATE | CODE | PROG|
--------------------------------
| 1 | 1996-08-16 | 24 | A |
| 1 | 1997-06-02 | 123 | B |
| 1 | 1997-08-19 | 23 | A |
I'm struggling to come up with a solution to this, so any help greatly appreciated!
Microsoft SQL Server 2012 (X64)
The following works with your test data
SELECT ID, date, MIN(code), MAX(prog) FROM table
GROUP BY date
You can then use the results of this query to create a new table or populate a new table. Or to delete all records not returned by this query.
SQLFiddle http://sqlfiddle.com/#!9/0ebb5/5
You can use min() function: (See the details here)
select ID, DATE, min(CODE), max(PROG)
from table
group by DATE
I assume that your table has a valid primary key. However i would recommend you to take IDas Primary key. Hope this would help you.
