DataSource Controls :: Sql Table Relationships / To Create A Dependency Between The 2 Tables

May 3, 2010

I have a table that contains item data. If the item is a particular type further information exists to describe the item. The additional information isn't that heavy however the number of records in relation to the main file will be quite small (less than
5%).

So I have 2 scenarios:1) Put the additional data in the main table and take tha hit on storage

2) Create an additional table and link the 2 together

If we were talking huge amounts of data I can understand that 2) would be the obvious choice but given the simplicity should 1) be a consideration?

If 2) is the answer - is it possible to create a dependency between the 2 tables when the item is 'that' particular type. In other words wnsure the addition data is populated for the required items and not others.

DataSource Controls :: How To See The Size Of The Individual Tables

May 13, 2010

From using the command: EXEC sp_spaceused on a SQL 2008 database,

the DB has a size of 642.56 MB, unallocated space 148.77 MB.

I can also see the size of the individual tables from the same command:

Reserved: 103656 KB
Data: 98264 KB
Index_size: 2656 KB
Unused: 2736 KB

What I don't quite get is why the total database size is 642.56 MB when the size of the individual tables is so much smaller. We pay for the total amount, in chunks of 500 MB. I was trying to see which tables where causing the DB to be so big, but to me, it looks like it is not the size of the tables but something else.

What should I look at to figure out why we are taking up so much space? Am I not understanding how this works?

DataSource Controls :: Generating Tables From Entities

May 13, 2010

I'm creating entity on a project to use them as data on my website. I got my base simple entity Users and my DataContext. The thing is i would like the database to create the table as i create Entities.

I mean, actually my database doesn't have a Users table and do not generate it as i build and launch the project. I used to be a Java dev and in Java the table can be created with JPA so i guess Microsoft made it possible with ASP.net but how to do? I've looked on the web but didn't find it.

DataSource Controls :: Tables For Particular Presentation Of Data

Jun 29, 2010

Apologies if this is in the incorrect forum.. just a question about how to best structure some tables for a particular presentation of data. In the following table (2nd column) you'll see that each motorcycle product applies to a range of years. What is the best way to store this range of years in a relational db? At the moment I have a datefrom and a dateto field for the two ranges, but that may complicate things when I want to filter the table by a particular year. E.G. datefrom is 2006 & dateto is 2010 and I would like to filter by products for a 2008 model.

DataSource Controls :: Concatenating Rows From Another Two Tables

Apr 13, 2010

I have a problem where I would like to get a comma-separated list of items from a couple of tables as part of a set of results. All the searching I've done so far has produced results for dealing with one or two tables. I have four, and can't get my head around how to adapt the sql to deal with it.

I have the following layout:

*Table_Castings*
+---- CastingID {PK}
| MouldID

| SerialNo

| CastRef

| MeltCode

| Signature

|

|

| *Table_CastCertificates* *Table_Certificates*

| CertificateID {PK} ----------- CertificateID {PK}

+---- CastingID {PK} Description

FileID -----------------+

|

|

*Table_CertificateFiles* |

FileID {PK} -------------+

FullLocation

The results I would like include the following columns:

CastingID, MouldID, SerialNo, CastRef, MeltCode, [Certificates],

Where Certificates is a comma separated list of Description + " " + FullLocation records. (What I'll actually do is add http:// and other html codes to make FullLocation a hyperlink, but I can do that.)

Some SQL I've already got is this:

DECLARE @str VARCHAR(500)

SELECT @str = COALESCE(@str + ', ','') + '<a href="http://' + Table_CertificateFiles.FullLocation + '">' + Table_Certificates.Description + '</a>'

FROM Table_CastCertificates INNER JOIN

Table_Certificates ON Table_CastCertificates.CertificateID = Table_Certificates.CertificateID INNER JOIN

Table_CertificateFiles ON Table_CastCertificates.FileID = Table_CertificateFiles.FileID

WHERE (CastingID = 45)

SELECT output = @str

This actually gives all records in the for the specific casting, but I keep getting an error at the "=" in @str = COALESCE when I try joining it to another query to get each casting.

DataSource Controls :: Sql Statement To Get One Record Each From Two Tables?

Feb 2, 2010

I don't know if I'm posting this in the right place - I have a feeling it can't be too difficult but I can't seem to figure it out. I've come across this problem many times and I've never solved it. I would imagine the scenario is commonplace - I have a table of Products with a PK of ProductID, and a table of related images with a FK of ProductID. Each product can have many images, but for my initial display I want to display one product record with one image record. I have a Sequence field in the Images table and I could pick the lowest one. Right and left Joins return too many records - if I have three images for Product 1 then Product 1 is listed three times.

I've gotten around this before using a flag in the Products table, or listing an image in both tables but I'm sure there must be a SQL statement that can get the information that I need.

DataSource Controls :: Combine Data From 2 Tables

Mar 27, 2010

I have 2 tables with UserId and FirstName, LastName Columns that I want to combine the data in a Select Statement or Stored Procedure

1. The 2 tables will never have the same data, each table will be distinct

2. I want to combine first and lastnames to a full name (t1.FirstName + ' ' + t1.LastName) AS FullName

3. The statement will be used to populate a dropdownlist with UserId as Value, and Name as text

I am unsure how to accomplish this since I do not need to connect the tables, but combine the Sum of their data.

DataSource Controls :: SQL And Linking 2 Tables To Check Value?

Apr 12, 2010

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:

[Code]....

[Code]....

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..
