In Excel, records are entered in single rows going across, and columns.
I have a searchable online Mysql (using PHP) working database, with a single table to query same which so far is working great. All my online input queries work great, except for one which eludes me to date:
I would like to Query & ECHO results of each Company related information ONCE, followed by each person that works within each Company - then, next Company data again followed by all employees within it, Etc... all in one query without repeating the Company information again which is redundant.
I have been tried my best to research the above for a few weeks before asking for your help. I would appreciate any guidance you may be able to offer me related to this task - Thank you in advance for your time and guidance !
Here's a possible solution: Do a SELECT DISTINCT on your "station" field. This will return you a set of all unique stations.(read about distinct selections here)
Put that data into an array called $uniqueStations or something.
Then you can use a foreach loop to go through each value in $uniqueStations and echo out employee data with a different SELECT based on the unique station. (More on foreach here)

I am in need of creating a table that will get its data from a database (this is done:) ).
The users must be able to filter the table if they want to find specific rows based on the their input.
The table will have around 33 columns which not all of them will be visible, but the user can drag and drop new columns whenever he likes. and be able to filter the table using values from these columns as well.
The table will look like this and every time the user inputs something on the top of a column then the table will get filtered based on that column. also multiple filters can be placed.
Any suggestions on how to do this? is it even possible?
I would like suggest you to use http://yadcf-showcase.appspot.com/DOM_source_chosen.html jquery plugin for datatable also it works with ajax source

I have a data set of searches made on a website. I have to find top searches from that data set. The problem is, i cannot think of a way to do it. The search terms are long sentences. How could i find what are users interested in? It seems to be a problem of counting and i am using php. Any suggestion would be appreciated.
You can create a table in database, which will contain columns search_phrase and counter. Each time when user will search same phrase, you'll just increase counter instead of creating new row.
You can also create a script which will take all records from this table, and find similar phrases.
You can make counter corresponding to each phrase. Suppose You have a queries in long sentence format , divide your sentence into smaller parts and identify the most meaningful word and avoid the conjuctions and other verbs. Particularly focus on Nouns. For an eg, Query is : How to Make account on stackoverflow? Possible Solutions[words] : account, stackoverflow,make. Possibly in this way you can solve it.

I am creating a website where users can easily calculate the calories they eat and see the repartition in term of fat, carbo, etc.
I want the users to be able to retrieve data from previous days.
I then need to store the data sent by my users everyday (basically, they input how much of each food they have eaten everyday and I am making the calculation then store the results).
The question if the following: what would be the best way to store the data? I have to store the data for each user for each day. I can't think of a simple solution (I think creating a new table for each new day would not be great, would it?).
I'm using PHP and MySQL for now.
Thanks for the help!
It seems that you are a step ahead of your self with the daily breakdown question.
First, you need to decide what you need to store, e.g. fields and normalise the way they are stored.
For example, you would have the following tables:
Users:
Id
..
EatItems:
UserId
ProductId
Calories
Fat
DateTime
Once you have these tables up and running, you can build reporting layer on top of that to breakdown consumption by user / date or anything else you might be interested in.
You could have a table that holds the input/calculated data/date which relates to a user/account.
When the user views previous day's, select the data that relates to that user.
I wouldn't create a table for each day. One table would suffice.
However, I would suggest attempting something and posting the code for specific issues you have if you run into before posting here.

I've read tons of questions who are in many ways the same as this one. But I just can't seem to understand how I am supposed to do this the proper way.
I've got one table with my pages.
And one table with portfolio items.
I want to be able to say to a portfolio item: You are linked to the welcome page now.
My approach:
In my pages table i've created a "items_linked" column. Inside this column the id's of the linked portfolio items get stored.
In the html of the 'edit page' I have a select with all my portfolio items, whichever I select gets stored inside the "items_linked".
I use the mysql UPDATE to get the information inside the database.
However this way I can't link a portfolio item to more than 1 page.
Because UPDATE removes the old information.
So I was guessing I needed a way to keep the old info, and add new info if the item is linked to a second page.
Can someone push me into the right direction?
Since we have no way of knowing what we are replacing I can only give you an idea of what to do:
UPDATE `table`
SET `myColumn` = CONCAT(`myColumn`, other_data)
WHERE some_condition_exists
This causes the information in myColumn to have additional data appended to it.
Here's the thing (caveat ahead): If you need one item to be linked to many items what I have described is not the way to go. You should have a table between the two you have already which will allow a one-to-many relationship between pages and portfolios. Please consider refactoring your database design.

I have a school project and i hit a small snag . I just learned some basic mysql and i can work with single tables/row such as register users , validating logins and outputting all the data in a table.
I now have a more complex issue and i'm not very sure how to proceed .
I need to create a 'courses' that have several subsections such as :
(1) A course can have different lectures for each semester
(2) A lecture has its specific tutorials & labs ( more than one )
I know how to create a single row such as : username , frst name , last name , email etc....
But for the stucture below - i'm not really sure how to do this. I don't have a pre-existing code yet as i have not yet decided how to proceed .
i'm thinking about adding more than one data in the fields like : sections ="TA,TB" but i read that its not recommended in mysql
(source: 4.ii.gl)
(source: 2.ii.gl)
You schould make multiple tables.
One for courses. One for lectures and one for tutorials etc.
Then you bind them togheter woth unique IDs
