Question

I have an SQL Query that i\'m running but I only want to select a specific row. For example lets say my query was:

Select * from Comments

L

Answer 1

Select from tablename limit nthrow,1;

Answer 2

For SQL Server 2005:

select rank() OVER (ORDER BY c.subject, c.date) as rank, c.subject, c.date
   from comments c
   where rank = 8

Answer 3

select top 1 *
from TableName
where ColumnName1 in
(
    select top nth ColumnName1
    from TableName
    order by ColumnName1 desc
)
order by ColumnName1 desc

Answer 4

This is a classic interview question.

In Ms SQL 2005+ you can use the ROW_NUMBER() keyword and have the Predicate ROW_NUMBER = n

USE AdventureWorks;
GO
WITH OrderedOrders AS
(
    SELECT SalesOrderID, OrderDate,
    ROW_NUMBER() OVER (ORDER BY OrderDate) AS 'RowNumber'
    FROM Sales.SalesOrderHeader 
)  

SELECT * 
FROM OrderedOrders 
WHERE RowNumber = 5;

In SQL2000 you could do something like

SELECT Top 1 *FROM
[tblApplications]
where [ApplicationID] In
(
    SELECT TOP 5 [ApplicationID]
    FROM [dbo].[tblApplications]
    order by applicationId Desc
)

Answer 5

How about

SELECT TOP 1 * FROM 
   (SELECT TOP 8 * FROM Comments ORDER BY foo ASC)
ORDER BY foo DESC

Answer 6

SELECT * FROM comments WHERE ...conditions... LIMIT 1 OFFSET 8

OFFSET is a good thing for MySQL
