View 1 RepliesSQL Server :: Slow Running Query Based On Multiple Tables Using Joins
Nov 15, 2010One of my peer wrote a query based on multiple tables using joins. One of the table is in a different database The query was taking much time
1. Create an SP
2. Create a temp table and copy all records from the external db
3. Avoid using Left Join as much as possible and use Inner Join
4. Create and use indexes
5. Remove tables/columns that are not necessary
In this scenario, I would like to suggest to use Covering Index, but how can it be created for multiple tables and a temp table?
DataSource Controls :: How To Optimize Query With Multiple Inner Joins
Mar 22, 2010I have one question regarding how to make the below mentioned type of query more optimized so that mine query perfomace can be increased.
Select a.name1,a.address1,b.field3,c.field4,d.field6,e.field7
from a
inner join b on a.id=b.id
inner join c on c.id=b.id
inner join d on d.id=c.id
iner join e on e.id=d.id
union all
Select a1.name1,a1.address1,b1.field3,c.field4,d.field6,e.field7
from a1
inner join b1 on a1.id=b1.id
inner join c on c.id=b1.id
inner join d on d.id=c.id
iner join e on e.id=d.id
union all
Select a2.name1,a2.address1,b2.field3,c.field4,d.field6,e.field7
from a2
inner join b2 on a2.id=b2.id
inner join c on c.id=b2.id
inner join d on d.id=c.id
iner join e on e.id=d.id
All the above three select query at last using the same inner join condition, means last two inner join condition are the same for all the select query.
Is there any way so that this query can be optimized?

SQL Server :: Sql Query - Vertical Records For Particular Part_no Should Be Horizontally Displayed In A Single Row
Nov 25, 2010I have a sql table like this-
Sno part_no desc supplier currency price
1 10245890 abc abc electricals INR 0.320000
2 10245890 abc abc electricals INR 0.560000

4 10345780 def xyz electricals YEN 0.345678
5 10345780 def pqr electricals USD 0.000678
Now whenever user input the part_no output should be displayed like this- foe eg.. if user input 10245890, the ouput should be like this-
Sno part_no supplier1 currency1 price1 supplier2 currency2 price2 supplier3 currency3 price3
Means vertical records for particular part_no should be horizontally displayed in a single row. How can i write a sql query to achieve this?
DataSource Controls :: Using LINQ To Pull Out A Single Value From A Single Result Row Of A Join Query?
May 25, 2010For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.

SQL Server :: Table Joins And Datasets To Bind The Gridview In Page
Mar 25, 2011I have a web service with a dataset and I need to fill a gridview in my web page with data from multiple tables (like 4). How can I retrieve data from my 4 tables and construct a datatable with a table adapter in the dataset? I need to create this in the web service to bind the gridview in my page. In SQL I create a view with the joins of the 4 tables and added the view to the dataset. It works fine, but for other windows in my web page I need to use like 8 trough 10 tables (just to retrieve one field of each one) and I don't know if making that huge joins is the more efficient way to retrieve data from the server. There is another way to make joins? (Make separate queries for each table and create one table in memory) How?
View 2 RepliesSQL Server :: 2008 Views And Table Joins - Retrieve Data At Once When The Page Loads
Mar 21, 2011I have a web page with a GridView and a table outside the gridview to display more information of the record when it is selected (like record details). I'm using data of five tables for this particularly window. I use one table of the five to bind the gridview the other tables are for the details, but I use like 1 or 2 fields of those tables. I'm binding the page with web services. I need some advice on which is the better way for doing this to make a faster web page.
In sql server I made a view with the five tables (all the tables relations are working perfectly). In the web service I call the view; and in the web page I call the web service to bind the page. Everything is working. All I want to do is retrieve from the server all the necessary data only once when the page loads and bind the five tables data (like 18 fields total) in the gridview which I only show 12 fields the other 6 fields are hidden, those 6 are for the details which I get with jQuery (that's another topic). Bind everything only once and manage the data on client side. Everything is working perfectly. Here is my doubt.
How are the maximum table joins I can make? To retrieve the data via web and not get a server time out error. Which is a better way to make a faster page? Make 2 views one for the gridview and one for the details and put each view in a web service; or make one view with all the table joins and one web service. Right now all is working but I have to make other pages that use different tables and joins and I don't know if the server gets me the time out error when the page is fully working.
SQL Server :: Query From MDB Files Error "cannot Be Used For Distributed Queries Because The Provider Is Configured To Run In Single-threaded Apartment Mode"

SQL Server :: Weighted Keyword Search?
Oct 25, 2010I am searching for products out of my database:
AND (CONTAINS(P.name,
@contains_key)
OR
CONTAINS(P.description,
@contains_key)
OR P.sku
like
'%'
+ @Keywords
+
'%')
As you can see I'm using the CONTAINS statement and searching against the name and description fields.I would like to give the results a weight (or score) based on how often the word shows up and in what field.Example:if the word shows up in the name field -- give it 2 points every time the words appears.if the word shows up in the description field -- give it 1 point every appearance.Then ORDER the query based on the Score. And, perhaps add a where clause that the Score > 1 or some value.I realize, I will probably have to re-write my query and this "point" system may not be possible, but I know there is a way to weight results, but can't find any help online. I would also assume, this would be done in temp tables and select statements and directly in the where clause.

SQL Server :: Setting Up The CASE Keyword In SQL From Web App?
Mar 7, 2011I was wondering how I would go about setting up the CASE keyword in SQL from my Web app. I have a table where I need to update anywhere between 20 and 300 rows with different values. My table looks like this
ID EventID SeatType SeatCount Status Comments
On my page, these rows are listed in a table with a textarea to add comments. So when I click a button I need to update All the comments for all the users of a certain "EventID".I think my SQL Statement should go something Like this:
UPDATE Events
SET Comments =
CASE [code]....
Is that correct? I would be getting the ID and comment from each row of the table. Also (using C#) what would be the most efficient way to get this information into the query? I was thinking to use a for statement but I hear many string concatenations requires lots of processing?
[Code]....
SQL Server :: Incorrect Syntax Near The Keyword 'distinct'

7 1504 myname@hotmail.com 192.168.0.103 2010-12-08 18:26:01.447
Now, I want to select all unique locationid's from a single username, its important that the results can be PAGED and SORTED, I now have:
SELECT * FROM (select ROW_NUMBER() OVER (ORDER BY createdate) as RowNum,
distinct(locationid), l.*
FROM location_views lv
INNER JOIN locations l on l.id=lv.locationid
where lv.username='myname@hotmail.com'
) as info
WHERE RowNum > 0 AND RowNum <= 100
But this throws the error: "Incorrect syntax near the keyword 'distinct'."
ADO.NET :: How To Get Results Of Query (single Value) Into A Variable
Jan 16, 2011I have a Query which I run as an SQL. This is my SQL:
"SELECT COUNT(*) As NoDup FROM [XXX Dir] WHERE (FileName Like 'XXX_YYY_20100916.txt')"
The "XXX Dir" is a table and "FileName" is a text field within that table.
When I execute the SQL in the Query development windows, it returns a single value like 2.
I would like to assign that value to a variable so I can use it in my VB code.

Change Single URL Query String Value?
Sep 28, 2010I have an ASP.NET page which takes a number of parameters in the query string:
search.aspx?q=123&source=WebSearch
This would display the first page of search results. Now within the rendering of that page, I want to display a set of links that allow the user to jump to different pages within the search results. I can do this simply by append &page=1 or &page=2 etc.
Where it gets complicated is that I want to preserve the input query string from the original page for every parameter except the one that I'm trying to change. There may be other parameters in the url used by other components and the value I'm trying to replace may or may not already be defined:
search.aspx?q=123&source=WebSearch&page=1&Theme=Blue
In this case to generate a link to the next page of results, I want to change page=1 to page=2 while leaving the rest of the query string unchanged.
Is there a builtin way to do this, or do I need to do all of the string parsing/recombining manually?
