Analysing multiple rows to determine one status - ms-access

In one of my tables, some customers have multiple lines - this could be due to re-visits from technicians etc. What I want to do is for each customer ID, analyse whether a re-vist has taken place and place a marker against their name.
I have tried to combine an if/in statement that analyses the max/min visit dates for each customert ID. So if the max>min its classed as a "re-visit", however, i keep getting a syntax error.
Can someone help?

This is a job for two SQL queries:
1st query:
SELECT customerID, count(customerID) as visitCount
FROM tableOfInterest
GROUP BY customerID
2nd query uses first query:
UPDATE customerManifest INNER JOIN queryAbove ON queryAbove.customerID = customerManifest.customerID
SET customerManifest.multipleVisitIndicatorField to queryAbove.visitCount

SQL Temporary Table or Select

I've got a problem with MySQL select statement.
I have a table with different Department and statuses, there are 4 statuses for every department, but for each month there are not always every single status but I would like to show it in the analytics graph that there is '0'.
I have a problem with select statement that it shows only existing statuses ( of course :D ).
Is it possible to create temporary table with all of the Departments , Statuses and amount of statuses as 0, then update it by values from other select?
Select statement and screen how it looks in perfect situation, and how it looks in bad situation :
SELECT utd.Departament,uts.statusDef as statusoforder,Count(uts.statusDef) as Ilosc_Statusow
FROM ur_tasks_details utd
INNER JOIN ur_tasks_status uts on utd.StatusOfOrder = uts.statusNR
WHERE month = 'Sierpien'
GROUP BY uts.statusDef,utd.Departament
Perfect scenario, now bad scenario :
I've tried with "union" statements but i don't know if there is a possibility to take only "the highest value" for every department.
example :
I've also heard about
With CTE tables, but I don't really get how to use it. Would love to get some tips on it!
Thanks for your help.
Use a cross join to generate the rows you want. Then use a left join and aggregation to bring in the data:
select d.Departament, uts.statusDef as statusoforder,
Count(uts.statusDef) as Ilosc_Statusow
from (select distinct utd.Departament
from ur_tasks_details utd
) d cross join
ur_tasks_status uts left join
ur_tasks_details utd
on utd.Departament = d.Departament and
utd.StatusOfOrder = uts.statusNR and
utd.month = 'Sierpien'
group by uts.statusDef, d.Departament;
The first subquery should be your source of all the departments.
I also suspect that month is in the details table, so that should be part of the on clause.

MYSQL - Syntax for Joining My 3 Tables Correctly

Edit2: Chose to separate the queries and collate/handle the information as a whole outside of the database's output. Taking these out in a .CSV format, and adding them into Excel where I'm going to be running the actual numbers.
Query 1 to pull out orders and desired info:
SELECT
shipstation_orders_v2.id AS SSO_id,
shipstation_orders_v2.order_number AS SSO_orderNumber,
shipstation_orders_v2.order_id AS SSO_orderID,
shipstation_orders_v2.storename AS SSO_storeName,
shipstation_orders_v2.order_date AS SSO_orderDate,
shipstation_orders_v2.order_total AS SSO_orderTotal,
shipstation_orders_v2.name AS SSO_name,
shipstation_orders_v2.company AS SSO_company
FROM shipstation_orders_v2
GROUP BY shipstation_orders_v2.id,
shipstation_orders_v2.order_number,
shipstation_orders_v2.order_id,
shipstation_orders_v2.storename,
shipstation_orders_v2.order_date,
shipstation_orders_v2.order_total,
shipstation_orders_v2.name,
shipstation_orders_v2.company
ORDER BY SSO_orderDate
Query 2 to pull out fulfillments and equivalent info:
SELECT DISTINCT
shipstation_orders_v2.id AS SSO_id,
shipstation_fulfillments.id AS SSF_id,
shipstation_fulfillments.order_number AS SSF_orderNumber,
shipstation_orders_v2.order_number AS SSO_orderNumber,

shipstation_orders_v2.company,
shipstation_fulfillments.name,
shipstation_fulfillments.company
Edit: Question marked as answered. I figured out another way to do it that wasn't quite as harebrained. Props to DRapp for getting my brain moving.
Original Code is below Wall of Text
I'm a self-taught MySQL database user. I won't say administrator, since it's just me. I've put together a small database for work - about 60,000 rows and a maximum of 51 columns spread over three tables. I use this at work as a way to organize a fairly disparate sales data setup and make sense of it to identify trends, seasonality, all that good stuff. I work primarily with Shipstation data.
My problem is when I needed to introduce this third table. With two tables, obviously, it's just a simple JOIN. I got that working just fine. I'm having quite a bit of trouble setting up the JOINs correctly for this third table.
I'm attempting to JOIN the data from the two innermost queries to shipstation_orders_v2 and order_keys to the shipstation_fulfillments results I have in the third table.
For those of you who don't use Shipstation or aren't familiar with this element of it, fulfillments are in a different category than orders and don't use quite the same data. This is my dirty way of gluing them together so we have some decent, manipulable information on sales and shipping trends, etc.
I am making an internal query from shipstation_orders_v2 to order_keys as a way to SELECT DISTINCT the sum totals of split orders. I had problems with data duplication before I built up that subquery. With the (now) subquery and sub-subquery, the duping problem has been eliminated and with just those two tables it worked fine.
The issue is, when I'm making the SELECT from shipstation_fulfillments with a JOIN to the subquery and sub-subquery, I'm hitting a roadblock.
I've gotten several errors while working on this query. In order of occurrence and resolution:
Error 2013, lost connection to server during query (which told me I'm doing a full table read on three joined tables, since it isn't erroring out beforehand, but my rinkadink setup can't handle it). I got rid of that one.
Then, Error 1051 for an unidentified table name shipstation_fulfillments. To me I think it might be an issue for the query aliases. I am not sure.
Finally, good ole Error 1064, incorrect syntax on the first subquery after the
SELECT shipstation_fulfillments arguments.
Being self-taught, I'd virtually guarantee I'm merely missing an element of syntax somewhere that would appear fairly obvious to a well-practiced user of MySQL. Below is my current query setup.
If there needs to be any clarification, let me know.
SELECT
`shipstation_fulfillments`.`order_date` AS `orderDate`,
`shipstation_fulfillments`.`order_number` AS `orderNumber`,
(`shipstation_fulfillments`.`amount_paid` + `shipstation_fulfillments`.`tax_paid`) AS "Total Paid",
`shipstation_fulfillments`.`name` AS `name`,
`shipstation_fulfillments`.`company` AS `company`,

(
(SELECT
COUNT(`shipstation_orders_v2`.`order_key`) AS `orderCount`,

JOIN `order_keys` ON ((`order_keys`.`order_key` = `shipstation_orders_v2`.`order_id`)))) `t`)
JOIN `shipstation_fulfillments`
ON (`shipstation_orders_v2`.`order_number` = `shipstation_fulfillments`.`order_number`)) `w`
As a couple notes... As for long table names, no problem, but you can use alias references to them such as I have done via example ...ShipStation_Fulfillments SSF... the "SSF" is now an alias for shorter typing yet still makes sense of origin.
When changing column names in query via "AS", you only need the as if your column name result will change from its original as you had in the beginning such as SSF.order_date AS orderDate where you remove the "_" from the final column name, but also in "Total Paid" (yet I HATE column names with embedded spaces, let the user interface handle labeling things, but thats just me).
When typing table.column (or alias.column), doing via CamelCasing helps readability vs camelcasing slightly harder to read where the brain naturally breaks into readable words for us.
Other issue based on query. Outer query portions can't recognize aliases from inner closed queryies, only the alias of the subselect as you had with the "t" and "w" aliases.
Next, when doing JOINs, my preference is to read them in the way the tables are within the query listing the first one on the left, and whatever is joined TO on the right.
If went from Table A Join to Table B, the ON clause would be ON A.KeyID = B.KeyID vs B.KeyID = A.KeyID especially if you are going several tables... A->B, B->C, C->D
Any query with aggregates (sum, avg, count, min, max, etc) must have a "GROUP BY" clause to identify when each record should break. In your example, I would assume break on the original sales order.
Although this query IS NOT WORKING, here is a cleaned-up version of your query showing implementations from above.
SELECT
SSF.order_date AS OrderDate,
SSF.order_number AS OrderNumber,
(SSF.amount_paid + SSF.tax_paid) AS `Total Paid`,
SSF.name,
SSF.company
FROM
( SELECT
SSOv2.key_id,
SSOv2.order_number,
SSOv2.storename AS store,
SSOv2.order_total - SSOv2.shippingPaid AS OrderPrice,
SSOv2.ShippingPaid,
SSOv2.order_total AS OrderTotal,
SSOv2.QtyShipped,
SSOv2.name,
SSOv2.company,
COUNT(SSOv2.order_key) AS orderCount,
MAX(SSOv2.order_date) AS order_date,
SUM(SSOv2.shippingpaid) AS `SUM shippingPaid`,
SUM(SSOv2.order_total) AS `SUM Total Amount Paid`,
SUM(SSOv2.qtyshipped) AS `SUM qtyShipped`
FROM
( SELECT DISTINCT
OK.key_id AS key_id,
OK.order_key AS order_key,
SSOv2.order_number AS order_number,
SSOv2.order_id AS order_id,
SSOv2.order_date AS order_date,
SSOv2.storename AS storename,
SSOv2.order_total AS order_total,
SSOv2.qtyshipped AS qtyshipped,
SSOv2.shippingpaid AS shippingpaid,
SSOv2.name AS name,
SSOv2.company AS company
FROM
shipstation_orders_v2 SSOv2
JOIN order_keys
ON SSOv2.order_id = OK.order_key
JOIN shipstation_fulfillments SSF
ON SSOv2.order_number = SSF.order_number ) t
) w
Next, without seeing actual data or listed structures critical to solve the query, I will ask you edit your existing post. Create a sample table listing table, columns and sample data so we can see the basis of what you are aggregating and trying to get out of the query. Especially show where there could be multiple rows per order and fulfillment respectively and a sample answer of what you EXPECT the results to show.

Access SQL Append/Update Distinct

I'm trying to update a query I have, Access SQL (for now). It is currently a make table, but I want to change it into an update query, but only if the information isn't already in the end table.
Here is the current "Make Table" Query:
SELECT DISTINCT dbo_Us_postal_codes.[City]
,dbo_Us_postal_codes.[State] INTO dbo_ActiveZipCodes
FROM dbo_General_Client_List INNER JOIN dbo_Us_postal_codes ON
dbo_General_Client_List.ZipCode = dbo_Us_postal_codes.[Zip Code]
WHERE (((dbo_General_Client_List.ActiveCompany)=Yes));
US Postal Codes is a list of all US zipcodes, and their corresponding City, State.
What I want to do, is as General_Client_List is updated, run this query and add to ActiveZipCodes if the city/state combo isn't already there.
Add dbo_ActiveZipCodes to your query window. Join the City and state fields from the source table with an Left join to the matching fields in the dbo_ActiveZipCodes. Make the criteria for both Is Null.
Obviously test it as as select query first.

Removing Duplicating Issue in MySQL views

I have two tables called transactions (TransactionID, HotelID, service..) and services (id, userid, HotelID, type) and I need to create view from there. In here 1st table has 15 tuples and 2nd one has 8 tuples.
When I wrote this SQL query:
CREATE VIEW summary
AS
SELECT TransactionID, userid, HotelID, service
FROM transactions, services
WHERE transactions.HotelID = services.name
I got 105 results in summary view. How I get rid of this duplication issue.
As far as i understands your question, i think you need to use group concate and group by using join query.
using group by and group concate duplication of record will be solve.
and using join you can get common data from both table.
try below query.
currently i am not having knowledge of your table structure that's why i take assumption of your query and created my own tables and as per them created query.
Eg:
select
c.country_id,c.country_name,group_concat(s.state_id),group_concat(s.state_name) from country c inner join state s on c.country_id =s.country_id group
by c.country_id;
if you have any query feel free to ask.

Invalid results returning from a multi-table SELECT Statement

I have a Database with the following structure:
http://i.imgur.com/DFZz3Py.png
I'm trying to run a select statement, getting information from multiple tables, however it keeps bringing me duplicate results. The statement I'm using is:
SELECT StockReceipts.StockID, StockReceipts.Quantity, StockPriceHistory.Price
FROM StockReceipts,StockPriceHistory,Receipts
WHERE (Receipts.ReceiptID = 1) AND (Receipts.OrderDate BETWEEN StockPriceHistory.DateStart AND StockPriceHistory.DateEnd)
And the results i'm getting are:
http://i.imgur.com/2ZrgYyZ.png
What I actually want is matching rows from the stockreceipts table,
but with the price for each item of stock (the price that was within the date & time of ordering - OrderDate taken from the Receipts table) as well, taken from the StockPriceHistory table. I don't understand why it's making up duplicate/incorrect rows when there are only two rows in the StockReceipts table for that receipt.
Can anyone help? Thanks
SELECT
SR.StockID,
SR.Quantity,
SPH.Price
FROM
Receipts R
JOIN StockReceipts SR
on R.ReceiptID = SR.ReceiptID
JOIN StockPriceHistory SPH
on SR.StockID = SPH.StockID
WHERE
R.ReceiptID = 1
AND R.OrderDate BETWEEN SPH.DateStart AND SPH.DateEnd
You had no JOIN conditions between the tables leaving it a Cartesian result... For every record in one, grabbed entries from all other table rows.
