Hello,I am creating a simple blog system using SQL 2005.I have a Blog table:[BlogId] > PostId (PK), BlogTitle, ...And a Posts table[Posts] > PostId (PK), BlogId (FK), PostContent, PostLabels, ...PostLabels would have the following format:Label1,Label2,Label3, etc ...I will need to perform 3 actions:1. Get all posts in blog2. Get all labels in a post3. Get all unique existing labels in all posts in a blog and make a list.I am not sure if my approach of using a simple labels column in my Posts table is a good idea.So my other idea would be to add two more tables:[BlogLabels] > BlogLabelId (PK), BlogId (FK), LabelName ...[LabelsInPosts] > BlogLabelId (PK), PostId (PK)So my idea is:1. When creating a post one of the parameters would be a comma separating string with all labels for the post. Inside SQL Procedure I will need to loop through each label and check if it exists in BlogLabels. If not then I added it. For each label I add a records in LabelsInPosts. How to create this loop? Am I thinking this right?2. To get a list of all labels in a blog I would need to go to BlogLabels and get all labels which are related with posts in LabelsInPosts. Those posts must be only the ones that are related with my given BlogId. Grrr, this is getting really confusing for me. Is this possible to to? How?Please, give me some advice about all this.Thanks,Miguel
View 1 Replies View RelatedThe following sql works great when the field for my main blog message is type nvarchar but doesn't work for text which I need to convert to.
select
a.id, b.textField
count(b.a_id) as myCount
from a left join b on a.id = b.a_id
group by a.id, b.textField
What other methods could i use to get "myCount" within one sql statement?
Thanks in advance, Jeff
Hi,
I have a simple blog with a posts and replies table.
on the posts summary page i want to count the number of replies related to each post.
I thought i could store all the posts in a table variable and then loop through the table variable to count the number of replies that relate to the current post.
It doesnt seem as easy as i expected and i think i am making it more complicated for myself.
Can someone point me in the right direction please ?
The following statement seems to ignore my sort expression....how can I fix this? Select TB.* FROM TblBlogs TB JOIN (select top 20 blogId, count(*) cfrom tblCommentsgroup by blogIdorder by count(*) desc) T20 ON TB.BlogId = T20.BlogId
View 3 Replies View RelatedI've never worked with a column that's defined as a binary data type. (In the past if ever we had to include a photo we stored a link to the JPG/BMP/PNG/whatever into a column, but never actually inserted or updated a column with binary data.But now I've got to do that. So how do you put data into a column defined as BINARY(4096)?

I created my BI Blog and I need your feedback to my post SSIS-Populating Dimension. Do you think is a good approach? In my project works perfectly!

Hi. I am currently building a blog application, and I need some advice... I have the post title, post date, post by, etc stored in a database table, however I was wondering whether I should store the actual post content in the database as well or in a text file. For example, if the posts get really long would it slow down database performance or would there not be much of a difference? Furthermore, if I wanted to keep the posts private, a text file would not be ideal as it can be accessed easily by surfers... What do you recommend?Thanks a lot

There is my above sql script, i'm currently using mysql at home to test things but will convert to work in mssql.
I need to get associated BlogID for Certain ChannelID from the BlogAssociations table.
Then using those BlogID's that it finds for let just say ChannelID "1" list off the 3 most recent EpisodeID's from the Episodes Table per each BlogID.
So if ChannelID "1" has four BlogID's associated with it then in the Episodes table list off the recent 3 EpisodeIDs for BlogID "3", then the 3 most recent EpisodeIDs for BlogID "5" and so on and so on.
I have this which kind of does what I want:
Code:
select
e.BlogID, e.EpisodeID, e.other
FROM
episodes e, BlogAssociations ba
WHERE
e.BlogID = ba.BlogID and ba.ChannelID = '1'
ORDER BY
e.EpisodeID DESC;
It returns:
Code:
+--------+-----------+---------------------+
| BlogID | EpisodeID | other |
+--------+-----------+---------------------+
| 12 | 17 | Episode 17, blog 12 |
| 12 | 16 | Episode 16, blog 12 |
| 12 | 15 | Episode 15, blog 12 |
| 12 | 14 | Episode 14, blog 12 |
| 12 | 13 | Episode 13, blog 12 |
| 3 | 4 | Episode 4, blog 3 |
| 3 | 3 | Episode 3, blog 3 |
| 3 | 2 | Episode 2, blog 3 |
| 3 | 1 | Episode 1, blog 3 |
+--------+-----------+---------------------+
But as you can see it lists off 5 of the Episodes for BlogID "12", I only want the most recent 3 as previously stated. It also lists off more than 3 Episodes for BlogID "3". How in the world do I go about doing this?
I'm making this a stored procedure so I can't use php otherwise I wouldn't even be posting
Thanks so much!
