View 4 RepliesJust have a problem, I want people to join a mailing list, I just have a textbox and button. When a user enter's their email address, the address and time are inserted into a database. However, if the same email is added again I would like for a message to appear saying the record already exists.
Can someone show me how to do this, here is my current code:

Here I have specified a query which gives an idea about how to drop a constraint and recrate it..
[Code]....
Parent_TableName: is the name of the table where we actually reffer.
I have a situation where a query returns ~20 columns, but at any given execution only 5 of the 20 will have non-NULL values. The remaining 15 will contain null for every row in those columns.
I need to figure out which of the 5 columns have values. I am using a SqlCommand. How would I best approach figuring out these 5 columns?
i have a job application process where users apply for a job, in the admin section administrators want to be able to see which applications have not been viewed. Now i have one page which lists all the job vacancies and then users can click into that specific vacancy to see which people have submitted an application. This all works fine.
However on the page i display the job vacancies i need to make it so that if there are any applications within a vacancy that need viewing it appears in RED.
The two tables i am using are below:
tbl_vacancies
job_id
job_name
location
voucher
details
availability
region
date_added
tbl_applications
application_id
job_id
fname
sname
other_info
.
.
.
.
date_addedd
viewed
Now the viewed column is in tbl_applications table, the applications relate to a specific vacancy via the job_id.
So what i need to check is IF there are ANY applications where the viewed = 0, if so that means that there are applications that need to be seen, and i want this to appear in RED.
Now i tried this several ways i.e an INNER JOIN etc.. but the full list of vacancies won't appearing.
So i tried this:

This doesnt work at all. I have a datareader which runs through the returns, i don't get any errors, and the applications display correctly but when i use the IF to check it doesnt work..
I am having a problem. I need to check to see if a row has been displayed once, and if so don't display it again. I have the following code:
[Code]....
This all works perfectly, but displays the body row repeatedly. So i need to add a counter or something to check this and make sure it is only displayed once..
I tried with DISTINCT in the sql but that didn't work, so i think it may be better doing it through iteration? Can this be done?
