I need to show a report weekly for sales of a specific item "Phone1". When I currently run the report, if an employee does not sell that item it omits them from the report. I want to show them even if no sales.
I have tried a few options including (IsNull) and (IsNothing). These still do not have the expected outcome.
=IIF(IsNothing(Sum(Fields!New_and_Upgrade_Total.Value)), 0, Sum(Fields!New_and_Upgrade_Total.Value))
The result should show all employees withing the company even if they do not have a sale for that time frame.
EMP Name | Sales | Item |
Employee 1 | 0 | Phone1 |
Employee 1 | 5 | Phone1 |

I have a table of tickets to multiple dates of shows shows. basically, it looks like this...
+----+---------------+--------------+-----------+
| ID | ticket_holder | ticket_buyer | show_date |
+----+---------------+--------------+-----------+
ticket_holder and ticket_buyer are both user ids
If I wanted to count the total number of tickets that one ticket holder has, I could group by that holder and count the rows, but I want more stats than that.
I want to know a user's total bought tickets, how many they hold and how many shows they've bought tickets for.
+------+---------+--------+-------+
| USER | HOLDING | BOUGHT | DATES |
+------+---------+--------+-------+
| 1 | 12 | 24 | 7 |
+------+---------+--------+-------+
| 2 | 3 | 4 | 2 |
+------+---------+--------+-------+
| 3 | 1 | 2 | 1 |
+------+---------+--------+-------+
is it possible to put all this in a query, or do i need to do php stuff to make it happen?
I would do it in multiple queries. You can't group by either ticket_holder or ticket_buyer like you want, in a single query. If you try GROUP BY ticket_holder, ticket_buyer then it will group by both columns, which is not what you want.
SELECT ticket_holder, COUNT(*) AS tickets_held
FROM `a table of tickets` GROUP BY ticket_holder;
SELECT ticket_buyer, COUNT(*) as tickets_bought
FROM `a table of tickets` GROUP BY ticket_buyer;
SELECT ticket_buyer, COUNT(DISTINCT show_date) AS shows_bought
FROM `a table of tickets` GROUP BY ticket_buyer;
Not every task has to be accomplished in a single query! It's part of the design of SQL that it should be used by some application language, and you're expected to handle formatting and display in the application.
I have a table products and a table locations which are linked together in a many-to-many relationship with a table products_locations. Now a client can select a set of products, and I want to run a query that selects only the locations, where ALL of the selected products are available.
This seemed pretty straight forward at first, but I see myself being quite baffled by how to achieve this. I initially thought I could get all the correct location-ids with something like
SELECT location_id
FROM products_locations
WHERE product_id = ALL [the user selected product ids]
But on second thought that does not appear to make sense either (the structure of products_locations is quite simply [product_id, location_id].
Any suggestion on how to structure such a query would be appreciated. I feel like I am overlooking something basic..
EDIT: I am using mysql syntax/dialect
Quick sample: Given the following tables
| products | | locations | | products_locations |
| id | name | | id | name | | product_id | location_id |
|------------| |-----------| |--------------------------|
| 1 | prod1 | | 1 | locA | | 1 | 2 |
| 2 | prod2 | | 2 | locB | | 2 | 1 |
| 3 | prod3 | |-----------| | 2 | 2 |
|------------| | 3 | 1 |
|--------------------------|
If a user selects products 1 and 2, the query should return only location 2. If the user selects products 2 and 3, the query should return location 1. For 1, 2, and 3, no location would be valid, and for product 2, both locations would be valid.
I figured out a query that achieves what I need. Though it is not as clean as I had hoped, it seems to be a robust approach to what I'm trying to query:
SELECT t.location_id
FROM (SELECT location_id, COUNT(*) as n_hits
FROM products_locations
WHERE product_id IN [the user selected products]
GROUP BY location_id) t
WHERE n_hits = [the number of user selected products];
Explanation:
I create a temporary table t which contains every location_id that has at least one matching product in the user's selection, together with the number of times that location matches a product in the user's selection. This is achieved by grouping the query by location_id.
I select the location_id(s) from that temporary table t, where the number of hits is equal to the number of products the user had selected. If that number is lower, I know that at least one product did not match that location.
So I have two access tables:
Jobs Table:
JobID,
Customer,
Address,
Measure Date,
Install Date
Job Items:
JobID,
Item Name,
Item Length,
Item Width,
Item Quantity,
Item Cost
So what I want to do is add a field to the Jobs Table that shows the Total Value of all of the Item Costs with the same JobID.
How do I do this?
Edit:
Jobs:
+----+-------------+-----------------+--------------+--------------+
| ID | Customer | Address | Measure Date | Install Date |
+----+-------------+-----------------+--------------+--------------+
| 1 | Josh Manson | 22 Louis Lane, | 13/08/2016 | 27/08/2016 |
+----+-------------+-----------------+--------------+--------------+
Job Items:
+------------+-------------------------+-------------+------------+---------------+--------------------+
| Job Number | Item Name | Item Length | Item Width | Item Quantity | Item Material Cost |
+------------+-------------------------+-------------+------------+---------------+--------------------+
| 1 | Security Screen | 800 | 600 | 2 | $250.00 |
| 1 | Window, white aluminium | 700 | 400 | 3 | $150.00 |
+------------+-------------------------+-------------+------------+---------------+--------------------+
I would like there to be an extra column in the first table that adds all the Item Costs for that ID. For JobID 1 it would have a value of $400.
Sorry I'm not quite sure how to format tables properly in StackOverflow.
Create a query in the query designer, with both tables and their INNER JOIN.
Add functions/grouping by clicking the "Totals" button.
Add all fields from the Jobs table, they will all be set to "Group by".
Add Item Material Cost from the Items table, and set its "Total" to Sum.
That's it (well, you should set a column title for the sum column, or it will show in the query result as SumOfItemMaterialCost or something).
I'm doing a kind of point-of-sale system whose MySQL database has (among other things) a table with items for sale, a table with sales, and a table with purchases (a purchase being my ad-hoc notation for any single item bought in a sale; if the same person buys three items at once, for example, that's one sale consisting of three purchases). All these tables have logical IDs, viz. item_id, sale_id, purchase_id, and are easily joined with simple pivotal tables.
I am now trying to add a discount feature; basically your garden-variety supermarket discount: buy these particular items and pay X instead of paying the full sum of the regular item prices. These 'package deals' have their own table and are linked to the items table with a simple pivotal table containing deal_id and item_id.
My problem is getting to the point of figuring out when this is to be applied. To give some example data:
items
+---------+--------+---------+
| item_id | title | price |
+---------+--------+---------+
| 12 | Shoe | 10 |
| 76 | Coat | 23 |
| 82 | Whip | 19 |
+---------+--------+---------+
sales
+---------+-----------+
| sale_id | timestamp |
+---------+-----------+
| 2973 | 144995839 |
| 3092 | 144996173 |
+---------+-----------+
purchases
+-------------+-------------+---------+----------+---------+
| purchase_id | no_of_items | item_id | at_price | sale_id |
+-------------+-------------+---------+----------+---------+
| 12993 | 1 | 12 | 10 | 2973 |
| 12994 | 1 | 76 | 23 | 2973 |
| 12996 | 1 | 82 | 19 | 2973 |
| 13053 | 1 | 12 | 10 | 3092 |
| 13054 | 1 | 82 | 19 | 3092 |
+-------------+-------------+---------+----------+---------+
package_deals
+---------+-------+
| deal_id | price |
+---------+-------+
| 1 | 40 |
+---------+-------+
deals_items
+---------+---------+
| deal_id | item_id |
+---------+---------+
| 1 | 12 |
| 1 | 76 |
| 1 | 82 |
+---------+---------+
As is hopefully obvious from that, we have a shoe that cost $10 (let's just assume we use dollars as our currency here, doesn't matter), a coat that costs $23, and a whip that costs $19. We also have a package deal that if you buy both a shoe, a coat, and a whip, you get the whole thing for $40 altogether.
Of the two sales given, one (2973) has purchased all three things and will get the discount, while the other (3092) has purchased only the shoe and the whip and won't get the discount.
In order to find out whether or not to apply the package-deal discount, I of course have to find out whether all the item_ids in a package deal are present in the purchases table for a given sale_id.
How do I do this?
I thought I should be able to do something like this:
SELECT deal_id, item_id, purchase_id
FROM package_deals
LEFT JOIN deals_items
USING (deal_id)
LEFT JOIN purchases
USING (item_id)
WHERE
sale_id = 2973
AND item_id IS NULL
GROUP BY deal_id
In my head, that retrieved all rows from the package_deal table where at least one of the item_ids associated with the package deal in question does not have a corresponding match in the purchases table for the sale_id given. This would then have told me which packages don't apply; i.e., it would return zero rows for purchase 2973 (since none of the items associated with package deal 1 are absent from the purchases table filtered on sale_id = 2973) and one row for 3092 (since one of the items associated with package deal one—namely the coat, item_id 76—is absent from the purchases table filtered on sale_id = 3092).
Obviously, it doesn't do what I naïvely thought it would—rather, it just always returns zero rows, no matter what.
It doesn't really matter much to me whether the resulting set gives me one row for each package deal that should apply, or one for each package deal that shouldn't apply—but how do I get it to show me either in a single query?
Is it even possible?
The problem with your query above is that sale_id is also NULL in the missing row that you're interested in, due to the LEFT JOIN.
This query will return the deal_id for any deals that DO NOT apply to a given order:
SELECT DISTINCT
pd.deal_id
FROM package_deals pd
JOIN deals_items di on pd.deal_id = di.deal_id
WHERE di.item_id NOT IN (SELECT item_id FROM purchases WHERE sale_id = 3092)
From that it's easy to work out the ones that do apply. Note that for a fully functioning system, you'd still need to take the purchase quantities into account - e.g. if the customer had bought 2 of two the items in the deal, but only 1 of the third... etc.
A SQL fiddle demonstrating the query is here: http://sqlfiddle.com/#!9/f2ae4/8
Note that I've made my joins using the ON syntax, as I'm simply more familiar than with USING. I expect that would work too if you prefer it.
I'm working with SharePoint Lists, I have 2 Lists for this issue i.e. Movies & Theatres. Only one list is used tough, because Theatres reference a movie.
(I know this is weird but I'm not actually working with movies and theatres, it's just using an analogy so anyone could understand the problem so let's assume each Theatre only plays a single movie :-P )
So from the Theatres list I create a dataset with following fields: Linked_Movie (Title), Country, Theatre_Number.
I want to create a report that shows a tablix that lists all Movie-titles with all the countries it's shown in and a count of the theatres that are playing that movie. So the tablix should look like example below:
MovieTitle | Country | # of theatres
| |
Movie 1 | Country A | 5
| Country B | 10
SubTotal | 2 | 15
| |
Movie 2 | Country C | 15
SubTotal | 1 | 15
| |
Total | 3 | 30
I have already created a tablix which groups on Linked_Movie first and Country second. Then in the details-section I just count the theatres that play that certain movie in that specific country. To achieve this I created a second dataset with the exact same data so I could use LookUpSet.Length. But even though my calculations are correct the tablix still generates a row for each individual theatre. So my tablix actually looks like example below:
MovieTitle | Country | # of theatres
| |
Movie 1 | Country A | 5
| | 5
| | 5
| | 5
| | 5
.... | ... | ...
So if anyone knows how I would be able to achieve a tablix like the first example that would be greatly appreciated.
If anything is still unclear please don't hesitate to ask.
Kind regards

I was able to solve it by adding a calculated field to the dataset named MovieCountry.
After this I put the expression below as the condition for 'Row visibility' and the visiblity of the '=(Details)' properties:
=iif(Fields!MovieCountry.Value = Previous(Fields!MovieCountry.Value), True, False)
This way I only get a single row for each movie and country combination.
Any questions are always welcome!
