I know I can use "First" to specify a number of rows to return from a query but is it possible for the number of rows returned to be based on a parameter, something like this:
SELECT FIRST @someNumber name, age
FROM friends
WHERE age > @ageInput
Hello all.
Im trying to write a stored procedure which i can stipulate the top number of rows it returns. I know i use the following syntax:

And i know i need to pass the number of rows i want as a variable to the stored proceudre like:
@Top as Integer
But when i try and do the following. SQL Server complains about the syntax:
SELECT TOP @Top
Can anyone advise me how i should be doing this?

EDIT: added one more condition (in blue) into an IF statement.
Now it works incredibly fast.
I'm stuck. I have a table that I want to pull some info from that I don''t know how to.
There are two colomuns, one is the call_id column which is not unique and the other is the call_status column which again is not unique. The call_status column can have several values, they are ('1 NEW','3 3RD RESPONDED','7 3RD RESOLVED','6 PENDING','3 SEC RESPONDED','7 SEC RESOLVED').
i.e example, this is the existing data.
Call_id Call_Status
555555 3 3RD RESPONDED
235252 7 SEC RESOLVED
555555 7 3RD RESOLVED
325252 6 PENDING
555555 6 PENDING
325235 3 SEC RESPONDED
555555 1 NEW
This is the data I want...
Call_id Call_Status
555555 3 3RD RESPONDED
555555 6 PENDING
555555 7 3RD RESOLVED
The call_id could be any number, I only want the 6 PENDING rows where there are other rows for that call_id which have either 3 3RD RESPONDED or 7 3RD RESOLVED. If someone knows how it would be a great help.

Hi,
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?
I have table1 and table2.In table1 I have a column of numbers, numbers1.In table2 I have a column of numbers, numbers2.I'd like to select the highest number represented in either column.Example:table1:column1--------------345565643656555676table2:column2--------------3456564556456456456456The number I would want would be 56456 since it's the largest numberout of all combined.How can I get that number with one select statement?--[ Sugapablo ][ http://www.sugapablo.com <--music ][ http://www.sugapablo.net <--personal ][ Join Bytes! <--jabber IM ]

Hi,
I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

is there a way to process a file x records at a time?
We have a table that I need to append to an existing table. The date columns are currently in char but must be converted to datetime for the existing table. The problem is I have bad data. There are 3 million rows where the date field isn't valid for SQL's datetime format. Since this is the data I have, I have to work with it. I would like for SQL to just insert a null if it comes upon a bad date. Currently when it encounters a field that isn't valid, it stops the process with an error.
I have tried to go around it below, but there is still something "hanging" I would like to be able just to insert one million rows at a time and if it errors, then I can look at the next million, find the error, fix it and continue on.
Any suggestions? Or if you have a better idea all together I would love to see it.

1. The query should only return one record for each test id
2. The record returned should be the most recent. By most recent I mean the RN_EXECUTION_DATE and RN_EXECUTION_TIME of the returned row should be the most recent in time.
For example, in the sample data there are multiple rows with the same test id (for example 10668 and 10525. The 10525 is even more problematic since its execution date is the same for both rows returned - the execution times differ. Again, I want one record per test id and that record should be the most recent in time.

Hi All,
I'm a beginner in SQL and would like some help with writing a query that needs to:
a) Return the latest time that an event happened (along with the event), and also
b) Determine if this event occurred more than 30mins ago.
For example, Table EVENT consists of the following data:
EVENT DateTime,
A 16/1/08, 14:03:55
B 16/1/08, 14:30:27
A 16/1/08, 17:42:18
I would like the results for the first part of query to be:
EVENT DateTime,
A 16/1/08, 17:42:18
B 16/1/08, 14:30:27
I have tried creating a query based off this thread, but for some reason it kept complaining that the EVENT column in Table EVENT didn't exist.
For the part b), I have no clue as to what I should do apart from that I would need to use NOW().
Any help would be appreciated.
