In other SQL programs I have seen the use of Limit to tell it how many rows to return.
Is there an equivalent in MS-SQL that will let me do a quick Select clause and tell it how many rows to return.
In other words if I just wanted to see the first 10 rows what would I add to Select * from tableA
Thanks!
I am doing some SELECT queries on my database through ASP, but for example, I only want to return the 50 most recent entries that match the criteria. Is there any easy way to limit the number of results returned?
View 1 Replies View RelatedHello,
I am building a simple full text search engine for my site and I was wondering how would I retrieve rows 11-20 of the search result. This is required because I want to show my results only 10 at a time, like google does for instance. My query is as follows -
select top 10 ft_tbl.url,
ft_tbl.title, ft_tbl.body, ft_tbl.date,
(key_tbl.rank)
from mytable as ft_tbl inner join
freetexttable(mytable, (url, title, body),
'".$searchstring."', 10) as key_tbl
on ft_tbl.id = key_tbl.[key]
order by (key_tbl.rank) DESC
In MySQL I would use LIMIT but I believe that doesnt exist in MS SQL
Thanks
I'm busy writing a local site search engine that searches through a sql
server database and I want to know how or what is the correct sql
syntax to use in order to limit the amount of results a page loads at a
time? The idea is obviously similar to something like google where you
only see a certain amount of results first and then click at the botom
for the next eg. 10 results.
The second question is how do I, after the first page with the first
set of results that were shown, "clear" the second page of
the previous html in order to show the next set of results?
To give you an idea what my code looks like at the moment. Please don't
kill me if the code is done a bit a lame, because I'm still learning.

Hi,I need to limit results in the following query type:http://www.somewhere.com/php/sql-a....ql_order=&pos=1I found a reference that says I should be able to use LIMIT x[,y], butI don't know where/exactly how to add that to the string. Once I knowwhat it's supposed to look like, and can write something to generateit.If someone could post an example using the above and limiting theoutput to 100 records starting at position 1, that would be great.
View 1 Replies View RelatedI have a simple ForEach SMO Enumerator that returns the names of all the databases in the server identified by the SMO connection manager. I would like to populate the ForEach collection with just a subset of the names, based on some simple pattern matching. In his helpful book Integration Services, Kirk Haselden indicates that this can be done directly in the Enumerate field by adding qualifiers. However, I'm at a loss in regards to syntax.
What I have is: SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']
which returns the database names
What I want is to limit the names returned to those where Left(DBName,5) == "abcdb" (for example).
I have tried adding some test expressions to the Enumerate field, however, the URN is constructed based on the properties of a combination of the Connection Manager and Enumerate fields, and I'm just created invalid URNs.
Has anyone done something like this?

HI all !
I am having a bit of a problem trying to limit a number of columns in a matrix appearing on a page.
At the moment, I have a dataset that lists the month and the mail packages that were sent during the month
The matrix works great HOWEVER, if there were more than 8 months in the matrix columns, it does not break and would make the page look like a huge landscape page.
I am trying to limit the number of columns appearing (this is the months column) on the matrix so that the pages stay in a potrait position. IE: every 8 columns appear on one page. Is there an option or an expression I could use in the Matrix ?
Thanks!

I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow.

Where is this limit documented ?

I would like to know what the recommended Number of Sql Mobile Databases Per Application?

In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

Our development team wanted to create a database user for each application user in the application and use these for granular data access control, which at first, sounded like a good idea but our initial testing ran into some interesting results.
Our target user base was about 15 million users with an estimated 1% concurrency rate, and finding no MS documentation on an upper limit to the number of users a database can have we began some load testing to see how the database performed. In the hundreds of thousands of users range our test database had a hard time performing well under light loads (even without any concurrent connections).
When we purged the users and reverted back to just a handful of service accounts, performance went back to "normal" under the same loads. I began to wonder if this is a situation where throwing more hardware at the problem would overcome the issue or if there is a practical upper limit to the number of users a single database can handle well.
(There were of course other cons to this arrangement and I certainly was never going to expand the users tree in the object explorer for a database like this, but we thought it a solution worth investigating.)
What is the largest number of users any of you have had in a single database?
