The short answer is: No it can't be done, unless you have some other data that allows you to backtrack the relations.
There should be a table for the invoice rows, what content does that have?

There are definitely other tables in the mix, as is clear from the License table. I suspect that you can walk a relationship between those. All of those ID fields point to something, chase them down. My suggested starting points are LICENSETYPEID, LICENSESTATUSID, and LICENSECLASSIFICATIONID.
Keep in mind that you may need to join on GLOBALENTITYID to get useful results.

I'm taking a database driven website course. The teacher wants us to build a database driven website. I haven't touched a database in a yr since taking a sql plus course and even then never built a database from the planning stage. My idea is to build a website of my favorite music artist with their record album, year, song title, label stored in a database. This website will also have a database that when you click on the artist, a bio of the artist will appear. I also want to be able for the visitor to click a link and play song from my mp3 collection database. I have a database model of what I have so far that I can post. The teacher has given us very little direction other than a book called web programming and internet technologies. Everyone in the course is still in the dark about how to go about doing this project. Any ideas would be approciated on helping me design this. Thank you in advance.

Well, as it is a school assignment you are expected to do the work. However, there are lots of samples of website projects that you can find by doing a Google search, or look at some of the articles referred to at Beginner's Walk - Web Development[^]. The CodeProject articles section also has many database articles.

Hello experts,
I hope this question falls under the Database category.
I have this query:
Select e.Dept, e.division, a.managerID,e.EmpName,e.empnum, e.Email,e.zip, e.SSN FROM Emp e, Angular a Where e.empID = a.managerid OR e.empID = @empid and password=@pass
What I am attempting to do is that if a user attempts to log in and that user is a manager, redirect him/her to manager screen.
Otherwise, redirect to employee screen.
The issue is that when I run that query, I expect to see records associated with that manager.
It shows ALL employees belonging to different managers.
How do I tweak this to work?
A bit more info:
There are two tables, Emp table with following relevant attributes:
EmpName,
EmpID
Dept
Division
Password
SSN
User logs in with EmpID as username and last digits of SSN as password
Then this other table called Angular with following relevant attributes:
EmpID - FK to EmpID from Emp table
ManagerID FK to EmpID from Emp table
Status (done or pending)
The logic we are trying to employ is that if empID (from Emp table) that the user is logging in with matches ManagerID (from Angular table) then this must be a manager, redirect him or her to manger page.
If empID from Emp table does not match managerID from Angular table, redirect to employee table.
What am I doing wrong?
The code for redirect is asp.net and no need to post it here because if the query is correct, that will work.
Your assistance is greatly appreciated.

Something like this?
SELECT
e.Dept,
e.division,
a.managerID,
e.EmpName,
e.empnum,
e.Email,
e.zip,
e.SSN
FROM
Emp As e
LEFT JOIN Angular As a
ON a.managerid = e.empID
WHERE
e.empID = @empid
And
e.password = @pass

Hi,
I am using below code to display times as Pivot table grouped by date, this is basically for fingerprint attendance... I am getting what I want like this:
2012-06-03 10:23:30,10:23:32,10:24:05,10:24:07,10:24:24,10:24:26
How can I make the comma separated values displayed in columns instead of comma so it will be something like this
created_date - time1 - time2 - time3 - time4 --- etc
this is the code:
SELECT created_date, GROUP_CONCAT(created_time)
FROM fingerprint
GROUP BY created_date

How? We do not have access to your database so we have no way of correcting its content.
|
|
|
|
|
but atleast you can tell me the best possible solutions
|
|
|
|
|
The best possible solution is to learn all about database management. It looks like (but this is a guess since your question is not clear) that you have changed the schema of your database and now some of your records do not match the schema.
|
|
|
|
|
actaually as i said that if i write the query (which i posted in the forum) then i get the error....but if i write the same query using diffrent tables then it gives desired output
|
|
|
|
|
i have checked ...n both the tables are in same schema.
|
|
|
|
|
Then you need to investigate how you have records in one table that contain null values where they are not allowed.
|
|
|
|
|
that is what my issue that m getting null values though there is no column which has no records
|
|
|
|
|
Look at the error message you receive:
ERROR: null value in column "dt_open_date" violates not-null constraint
DETAIL: Failing row contains (VC2012030000303, VC20100300266, null, 11, 5, RBS, 1, 40, 40, 0, 14, 0, 1, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0).
It clearly explains, and shows, that you have a record with a null value where one is not allowed. You need to use your database management tools to find that record and fix its content.

ya i have checked it but ...there is no null vaue ....i just send u screen shot of my tables then hope u understand my issue ok.

Yes, I do understand your issue, but I do not think you do.
Either:
- You have a record in your database that contains a null value, or
- The
select dt_bill_date part of your update query does not find a record, so you are passing in a null value.
So, the solution is to find out why the select part of your update is returning a null value, or why that record contains null in the database.
|
|
|
|
|
thats wt how ,, i searched alot and tried solving but there is no null value though its giving
|
|
|
|
|
Run the select part of your query and see what value gets returned.
|
|
|
|
|
its returning the dates greater than 2015-07-01 without any null rrecords for dt_bill_date column of sc_bill table but i want same record to be displayed for dt_open_date column of sc_bill_detail ...thats what my requirement actually
|
|
|
|
|
I suggest you try modifying your code so it iterates through all the results doing the update for each found record.
|
|
|
|
|
i am not writting any code its only a query which i need to write according to the requirement as i told u btw my approach of writting query is correct ?or any other way to get it...coz i think its the simplest one?
