I am using Access 2007 on windows 7 Enterprise
I apologize if this has been covered, but I couldn't find it.
In a table where i have:
ID.....info.... place.... because
1..... abc ... home..... fridge
1 .... abc ... work....... desk
1..... abc.... play....... pockets
I would like a query that the result is
Id.. info....as1 .... as1...... as2..... as2 .... as3 ... as3
1....abc...home...fridge... work... desk... play.. pockets
the number of results by ID may vary, and the "Place and because" may not be the same.
any help is greatly appreciated
Thanks in advance
First, you need a column that uniquely identifies each row:
ID info place because id
1 abc home fridge 1
1 abc work desk 2
1 abc play pockets 3
Then, a union query to have all the records in a single column:
ID info rowID key value name
1 abc 1 place home as_1_place
1 abc 1 because fridge as_1_because
1 abc 2 place work as_2_place
1 abc 2 because desk as_2_because
1 abc 3 place play as_3_place
1 abc 3 because pockets as_3_because
Then you want a crosstab query on the name field
ID info as1_place as1_because as2_place as2_because as3_place as3_because
I will elaborate on this shortly.

I have control dashboard where multiple tables are listed with query
And in dashboard I can switch it to one table from ALLData to User1Table... and vice versa.
When there is only one table chosed I can easily manipulate data. However, I am struggling with updating rows when ALLData(all tables) are listed in dashboard. I can update it checking each table. I was wondering is there any better way to update it.
Tables have no DR. All tables have same column names.
//ALLData
SELECT * FROM users1
UNION ALL
SELECT * FROM users2...
user1
id name tel status
1 Bob 911 1
user2
id name tel status
3 Anna 11 0
3 Jack 12 1
//ALLData in dashboard
id name tel status
1 Bob 911 1
3 Anna 11 0
3 Jack 12 1
I can use id and status as PK
I have been trying to write a query which gives me data in a specific way, for example - Coulmns in database
ID Name Equipment Resolution DateTIme
1 xyz Pace Powercycle 2/10/2016 12:09
2 abc Aris Sent HIT 2/10/2016 12:09
3 xyz PAce Sent HIT 2/11/2016 12:09
4 xyz Pace Trouble Call 2/13/2016 12:09
When the data returns after the query it should look like
Count(Equipment) Resolution 1 Resolution2
1 Powercycle **Sent Hit**
1 **Sent Hit** Trouble call
Sent Hit from row 1 is same as that in row 2
How would i be able to achieve it?
Thanks for you help in advance.
It looks like you look for the cartesian product
SELECT COUNT(a.Equipment), a.Resolution AS 'Resolution1', b.Resolution AS 'Resolution2'
FROM tablename a, tablename b
I am pretty new to mysql and this site. I got an old mysql database (100.000 entries) to migrate to our new system. This is the old table:
CUSTOMER
Customer_ID Name Categories

5 Rick 13,2
And i need the following structure:
CUSTOMER
Customer_ID Name
1 Bob
2 Phil
3 Ines
4 Carol
5 Rick
Category
Category_ID Category_Name
1 Biker
2 Doctors
3 Teacher
... ...
13 Drivers
CustomerHasCategory
Customer_ID Category_ID
1 1
1 2
3 10
3 8
4 1
5 13
5 2
Thanks for any help.
I also had this problem but not in MySQL. I solved it with Python using the Pandas library. So, the exact steps I followed won't be useful for you. However, I'll show you the general idea behind the solution I used.
Below is image of the original column
First, I splitted the text into columns using the comas as the delimiter.
Next, I 'stacked' the columns
Finally, I removed the artefact column(s). So, I have only the ID and the values columns. This creates a one-to-many relationship.
I'm building a e-Commerce platform (PHP + MySQL) and I want to add a attribute (feature) to products, the ability to specify (enable/disable) the selling status for specific city.
Here are simplified tables:
cities
id name
==========
1 Roma
2 Berlin
3 Paris
4 London
products
id name cities
==================
1 TV 1,2,4
2 Phone 1,3,4
3 Book 1,2,3,4
4 Guitar 3
In this simple example is easy to query (using FIND_IN_SET or LIKE) to check the availability of product for specific city.
This is OK for 4 city in this example or even 100 cities but will be practical for a large number of cities and for very large number of products?
For better "performance" or better database design should I add another table to table to JOIN in query (productid, cityid, status) ?
availability
id productid cityid status
=============================
1 1 1 1
2 1 2 1
3 1 4 1
4 2 1 1
5 2 3 1
6 2 4 1
7 3 1 1
8 3 2 1
9 3 3 1
10 3 4 1
11 4 3 1
For better "performance" or better database design should I add
another table
YES definitely you should create another table to hold that information likewise you posted rather storing in , separated list which is against Normalization concept. Also, there is no way you can gain better performance when you try to JOIN and find out the details pf products available in which cities.
At any point in time if you want to get back a comma separated list like 1,2,4 of values then you can do a GROUP BY productid and use GROUP_CONCAT(cityid) to get the same.
I have a SharePoint list with 5 options (questions). Each option has a dropdown with values 1-6. The user (employee of a company) needs to select an option, then select a value from the dropdown and hit Submit. The selected value is unique. In other words, if the user selects the value 1 for the first option, that value cannot be chosen again. Here's an example form -
Category Rank
------------------------------
1. Work/Life Balance 4
2. Compensation 2
3. Commute 3
4. Work 1
5. Development 5
After filling the form, the data looks likes this on the Sharepoint list -
Employee Manager Work/Life Compensation Commute Work Development
--------------------------------------------------------------------------------
1. Employee 1 Manager 1 2 4 3 1 5
2. Employee 2 Manager 3 1 3 4 5 2
3. Employee 3 Manager 1 5 4 2 3 1
4. Employee 4 Manager 2 4 1 5 2 3
I'm able to get the Y-axis (for Rank) on the report just fine. The X-axis needs to display each category grouped by each Manager. Here's a sample of how I want it to look like -
Each colored bar on the X-axis is a Manager. This is my first time with SSRS (2012) and I'm just not sure how to accomplish this. If this is not possible, will moving the data to a SQL table in a different layout help? Any help is greatly appreciated.
You could aggregate each employee's response into an average in your dataset (I'm assuming you know how to do this):
Averages (just pretend)
Manager Work/Life Compensation Commute Work Development
--------------------------------------------------------------------------------
1. Manager1 2 4 3 1 5
2. Manager3 1 3 4 5 2
3. Manager2 4 1 5 2 3
Then you can use the categories as you have, with the manager as the series field. Pretty sure that should achieve what you're looking for.
