I'm looking for a bit of SQL code that will select some entries randomly from an SQL table.
For instance I'd like to feed a parameter in that contains the number
20, and the returned record contains 20 randomly and distinct selected
records.
Anyone know how this can be done? (never came across randomly select records)
Appreciate any help
lets say that this select statement will give me 100 records..
"Select UserID from Users where location = 'FL'"
from these 100 records, I want to randomly get 5 records. whats the best way to go about doing this
I need to randomly pick one or more records from a query e.g
select c_id, c_name
from c_table
where cat_id = 52
There may be more than one records for cat_id = 52. and I need to pick 3 of them randomly.
Thanks in advance!

I have a web app that calculates tax filing status and then stores data about the person.
Facts
The insert is done through a stored procedure.
All the sites that this program is being used are connecting through a VPN so this is not an external site.
The duplicate records are coming from multiple sites (I am capturing there IP address).
I am getting a duplicate about 3 or 4 times a day out of maybe 300 record inserts.
Any help would be greatly appreciated.
There are many sqlcmdInsert.Parameters("@item").Value =
cnTaxInTake.Open()
sqlcmdInsert.ExecuteNonQuery()
cnTaxInTake.Close()
And that is it.
I ran this query to populate a field with random numbers but it keeps populating with some duplicate records. how I can remove the duplicates?

From that I wanted to delete some records based on following condition. randomly select any number of records but sum(value) = 125 and name = xxx
I need to group up the records randomly into ‘n’ number of batches. That can be done by NTILE, but I want group up similar records in single group.
Say for example, following is the list of records I have in my table which I want to group into 5 batches
A123
A124
A124
A123
A127
After Ntile I will get the below,
Desired output is, Need output like Ntile but all same id should reside in single batch
Even if I n=5, maximum possibility of batches are 3 only.
Table1 contains fields Groupid, UserName,Category, Dimension
Table2 contains fields Group, Name,Category, Dimension (Group and Name are not in Table1)
So basically I need to read the records in Table1 using Groupid and each time there is a Groupid then select records from Table2 where Table2.Category in (Select Catergory from Table1)
and Table2.Dimension in (Select Dimension from Table1)
In Table1 There might be 10 Groupid records all of which are different.
I have a database which has a field called fldTimes. basically this field records the number of hits a file gets. How can I choose the most 5 popular files with the greatest hits. Thanks
View 2 Replies View RelatedIs it possible to use a SELECT to retrieve a Next 50 set of records?
Initial Query
Select top 50 email from table
What would the Query look like to retrieve the Next 50 records?
Thanks in advance.
This might be a simple question. I have a LIKE statement that is working fine, however I am not sure if something else is possible.
I can pull all records on a query for a person's name with a parameter value of "MARTIN". It will also pull records for "LYNN MARTIN". However, what if I would like to have that search also pull "LYNN M MARTIN"? Currently "LYNN MARTIN" is not finding "LYNN M MARTIN".
When the end user wants to search on LYNN MARTIN and that is what they input, I want SQL to find all records that match LYNN MARTIN and also find records that HAVE LYNN % MARTIN.
I hope this make sense? I guess I need to build my select statement using a WHERE LIKE statement, but I am not sure of the syntax.

Hi, my sql is not too hot so i hope someone can help me. I need to select all the records from one table that do not exist in 2 other tables.

Here is a shortened version of my code.

WHERE (DateOfStats NOT IN
(SELECT dateofstats
FROM table2)) and (DateOfStats NOT IN

i need to select records from table "A" if only the "PK" of "A" exists in table "B". I need to return a resultset not just a single record. The problem is table "B" is not a table in database instead a user supplied table which can be a datatable in memory.

How would I create a statement that would select 10 random records from the SQL DB?
View 5 Replies View RelatedHi,
Here is a basic example of the issue I am having:
Table 1 columns - name, address, zipcode, favorite food
For table 2 I want to find how many zipcodes exists and also take 20% of the count
Table 2 columns - based off Table 1 contains zipcode, count(zipcode) as ct, count(zipcode) * .20 as perc_ct
For example:
zipcode ct perc_ct
83746 10 2
93847 20 4
I want to run a query that will pull any 2 records for 83746 and any 4 records for 93847 from Table 1.
Is this possible?
What I need is the start and end time of each task, but the issue is there is no unique task number to bind them together..

I need to be able to split these into multiple tasks with the associated start and stop times.

Good Morning,I have a view that contains rate information, contractIDs, and effectivedates.I need to select the rate info based on contractID and date.I can provide a date and contractID, and I need to select the rate info forthat contract where the effective date is <= dateprovided.I need the 1 record that is closest to that date.I am thinking something with max() perhaps. Any ideas? The <= effectivedate will return several rows, I just need the one closest to the date Iprovide.Thanks for any advice,CK

I want to run a query that returns say 100 records...but I only want to return first 10 for first page on a web page, then on page 2 the webpage will return rows 11 to 20 of the same SQL statement...page 3 returns rows 21 to 30 rows etc....(eg. like Google or bulletin boards, browsing auctions in ebay etc.).
I could probably get my application logic to handle this (ASP.net), for instance I could possibly get a datareader to skip the first 10, output the next 10 then stop for page 2 (records between 11 amnd 20) but is there way to do this in SQL Server at the database level using an SQL Statement?
I can use TOP 10 to get the first set of records for the first page eg.
SELECT TOP 10* FROM Suppliers
...but how do I get between 11 and 20, 21 and 30 and so on?
I've already mentioned I could handle this in my application logic, but then each time the same SQL Statement is fetching all 100 records, even though the web page will only display a certain range. I'm building an intranet website that can potentially run queries that return 100'000s records, even though initially only top 20 or so records are display, each page they subsequently go to will rerun that same query that returns all 100'000 records. So handling this as part of the query would be better for performancr I reckon.
Someone gave me the syntax..
SELECT *
FROM employees
LIMIT 10,10;
..but it didn't seem to work.
Thanks for any help!!
