I am not sure what SQL is exactly, databases I think, would SQL be the thing to use?
I want it so that when a user types into a search box it displays a "did-you-mean" box, that also shows how many other people used that term but I will do later ;)
currently I just want the text to be saved into database (?) and also how many times it's been done.
(new to stackoverflow so sorry if format/whatever is bad)
You just need a three table named something like search_queries which has columns for: id, search_text, and count. Everytime somebody searches just increment the count column where search_text is equal to what they searched for. This is a really broad question though and you need to start by learning the basics and report back here with more specific questions.

I am doing a beginners' SQL tutorial and I started to wonder whether a simple SQL query on this table: http://www.sqlcourse2.com/items_ordered.html could tell the number of items (also 1) which have only been purchased more items at a time, so there is no record which contains the quantity column with a value of 1 AND the item. I am really beginner at this so please try to keep it simple.
Thank you in advance!
Welcome to the fascinating world of SQL.
Well - I'm not giving you the answer, but a hint (after all, it's a training and your own thinking and finding the solution would be the best way for you to learn something new).
The way you formulate your question is somewhat puzzling.
When I combine what you ask with what is possible with SQL, the question that would make sense to me would be that you need to list (or count, I did not understand that very well) the items (or the complete rows in the table with matching item, that was not clear either), that were never sold with a quantity of 1.
If that's what you need, you will need a subselect to get all distinct items that were sold with a quantity of 1, and select the rows from your base table whose item value is not in the list you get from the subselect.
Do you need more hints?

I am trying to write a query that 1) works and 2) shows meaningful information.
However, I can't seem to complete both scenarios. Both bits of code do work to a degree. My SQL query does work by showing all the useful information a user wants but when you click the edit button it doesn't link properly so it won't allow the user to update that row. The other shows only keys and rowid but when you click edit does show the information and allows it to be updated.
So as not to get another down-voted question, I have taken pictures of each scenario to show the problem, but, ultimately, I need to show meaningful information: an id or key isn't meaningful to the vast majority of users.
Here is my code
SELECT APPLICATIONS.APP_ID, APPLICATIONS.SRN, STUDENTS.SURNAME, STUDENTS.FORENAME, APP_STATUS.STATUS, METHODS.METHOD, JOBS.JOB_TITLE, APPLICATIONS.APP_DATE
FROM APPLICATIONS
JOIN STUDENTS
ON APPLICATIONS.SRN = STUDENTS.SRN
JOIN APP_STATUS
ON APPLICATIONS.STATUS_ID = APP_STATUS.STATUS_ID
JOIN METHODS
ON APPLICATIONS.METHOD_ID = METHODS.METHOD_ID
JOIN JOBS
ON APPLICATIONS.JOB_ID = JOBS.JOB_ID;
and here are the pictures of it in action
below is the code that does not show meaningful information but does work.
select "ROWID",
"APP_ID",
"SRN",
"STATUS_ID",
"METHOD_ID",
"JOB_ID",
"APP_DATE"
from "#OWNER#"."APPLICATIONS"
If i knew how to properly use rowid i am sure this is a simple feat but i dont so if i could get any help it would be useful
//edit
who ever renamed this to Application Expression why? what i am using is Apex Application Express it was relevant information that got changed to something wrong which might make it hard for someone with a similar problem to find later.
In the second, simple query, apex can determine which table (and record) you are trying to edit.
In the first query, with the joins, it can't tell which of the five tables in query you want to edit. You probably want to have the edit link pass the primary key of the row from APPLICATIONS to the child page. You would need to build into that page any logic (lists of values etc) that map lookup tables (such as status) to the values needed in the APPLICATIONS table.

1.site built by professional that left company,
2.I am inexperienced but trying/ want to learn,
3.Customer support site for service reps,
................................................
What im trying to do exactly per stackoverflows parameters.
We have a drop down box listing issues that the customer had in a column labeled "issue_type". I can export via csv entire table load onto excel then give to boss for overall review of what the issues were. However data base has a "hide" column. Its function is that when the row is updated the record is kept but the same "job or call" has only one viewable report on site (the most recently updated one). Hide is a boolean. In conclusion I want to export rows that only has the "hide" column Boolean status at 0, AND to only export the columns "customer", and "issue_type". I can seem to only do one or the other. and have researched a minimum of 4 hours to find answer myself and cannot find a syntax to do both at the same time with phpmyadmin.
I dont want an enormous data that is mostly useless but for issue type and customer but i will have to manually delete all the rows with hide = 1?
Thanks anyone 1st attempt question sorry if not correct for stackflow.
SELECT Customer,Issue_type FROM tickets where hide =0;
Elaborating on what is above for anyone that may be looking for a similar answer, SQL supports the "where" clause of which you can when properly syntaxed select many of your columns and their associated strings, booleans, and numbers to = what your looking for. Wildcards I found later for other uses work as well.
Sorry about the self answer but hopefully someone finds this usefull
it might be possible I'm searching for the wrong keywords, but so far I couldn't find anything useful.
My problem is quite simple: At the moment I get a list of individual Ids through a report parameter, I pass them to a procedure and show the results.
The new request is like this: Instead of showing the list for all individuals at once, there should be a list for each individual id.
Since I'm quite a beginner in srss, I thought the easiest approach would be the best: Create a subreport, copy the shown list, and create a subreport per individual id.
The amount of this IDs is dynamic, so I have to create a dynamic amount of subreports.
Funny enought, this doesnt seem to be possible. This http://forums.asp.net/t/1397645.aspx url doesnt show exactly the problem, but it shows the limit of the subreports.
I even ran trough the whole msdn pages starting http://technet.microsoft.com/en-us/library/dd220581.aspx but I couldnt find anything there.
So is there a possibility, to create a loop like:
For each Individual ID in Individual IDs, create a subreport and pass ONE ID to this?
Or is there another approach I should use to make this work?
I tried to create a 'Fake'-Dataset with no sql query but just for iterating the id list, but it seems the dataset needs a data-source...
As usual, thanks so far for all answers!

You didn't provide much detail about what sort of information needs to be included in the subreport, but assuming it's a small amount of data (say, showing a personnel record), and not a huge amount (such as a persons sales for the last year), a List might be the way to go.

All datasets require a data source, though if you're merely hard-coding some fake return data, any data source will do, even a local SQL instance with nothing in it.
I've got a spreadsheet that has the headings Operation, Priority and Specialty so all of the information for a specific operation is on one line and is stored as text.
I need to create a report for each Specialty that tells me the number of Operations done, which is easy (using COUNTIF), but also how many routine or urgent Priority Operations there were.
This would be easy in a database. I'd do it like this.
COUNT * FROM OPERATION_LIST
WHERE Specialty = "Cardiac"
AND Priority = "Routine";
I cannot for the life of me work out how to do this in Spreadsheet though.
I know Google Drive Spreadsheets have a QUERY function but I cannot work out how to use it for this and Googling for answers is no help. I'm sure it'll be obvious when I see it but I've been working on this for days now, with no luck.
Can anyone help?
I would do it like this:
=query(A:C, "select A,count(B) where B = 'Routine' and C = 'Cardiac' group by A label count(B) 'Count'",1)
Assuming that you have a header row (Operation, Priority, Speciality, which represent A,B,C in the query - respectively).
Hope this helps.
