In PostgreSQL there is the Limit and Offset keywords which will allow very easy pagination of result sets.

What is the equivalent syntax f

    In SQL server you would use TOP together with ROW_NUMBER()

    The closest I could make is

    select * FROM( SELECT *, ROW_NUMBER() over (ORDER BY ID ) as ct from [db].[dbo].[table] ) sub where ct > fromNumber  and ct <= toNumber
    

    Which I guess similar to select * from [db].[dbo].[table] LIMIT 0, 10

    This feature is now made easy in SQL Server 2012. This is working from SQL Server 2012 onwards.

    Limit with offset to select 11 to 20 rows in SQL Server:

    SELECT email FROM emailTable 
    WHERE user_id=3
    ORDER BY Id
    OFFSET 10 ROWS
    FETCH NEXT 10 ROWS ONLY;
    
    • ORDER BY: required
    • OFFSET: optional number of skipped rows
    • NEXT: required number of next rows

    @nombre_row :nombre ligne par page  
    @page:numero de la page
    
    //--------------code sql---------------
    
    declare  @page int,@nombre_row int;
        set @page='2';
        set @nombre_row=5;
        SELECT  *
    FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY etudiant_ID ) AS RowNum, *
          FROM      etudiant
    
        ) AS RowConstrainedResult
    WHERE   RowNum >= ((@page-1)*@nombre_row)+1
        AND RowNum < ((@page)*@nombre_row)+1
    ORDER BY RowNum

    For me the use of OFFSET and FETCH together was slow, so I used a combination of TOP and OFFSET like this (which was faster):

    SELECT TOP 20 * FROM (SELECT columname1, columname2 FROM tablename
        WHERE <conditions...> ORDER BY columname1 OFFSET 100 ROWS) aliasname
    

    Note: If you use TOP and OFFSET together in the same query like:

    SELECT TOP 20 columname1, columname2 FROM tablename
        WHERE <conditions...> ORDER BY columname1 OFFSET 100 ROWS
    

    Then you get an error, so for use TOP and OFFSET together you need to separate it with a sub-query.

    And if you need to use SELECT DISTINCT then the query is like:

    SELECT TOP 20 FROM (SELECT DISTINCT columname1, columname2
        WHERE <conditions...> ORDER BY columname1 OFFSET 100 ROWS) aliasname
    

    Note: The use of SELECT ROW_NUMBER with DISTINCT did not work for me.

    -- @RowsPerPage  can be a fixed number and @PageNumber number can be passed 
    DECLARE @RowsPerPage INT = 10, @PageNumber INT = 2
    
    SELECT *
    
    FROM MemberEmployeeData
    
    ORDER BY EmployeeNumber
    
    OFFSET @PageNumber*@RowsPerPage ROWS
    
    FETCH NEXT 10 ROWS ONLY
