In PostgreSQL there is the Limit
and Offset
keywords which will allow very easy pagination of result sets.
What is the equivalent syntax for SQL Server?

The equivalent of LIMIT
is SET ROWCOUNT
, but if you want generic pagination it's better to write a query like this:
;WITH Results_CTE AS
(
SELECT
Col1, Col2, ...,
ROW_NUMBER() OVER (ORDER BY SortCol1, SortCol2, ...) AS RowNum
FROM Table
WHERE <whatever>
)
SELECT *
FROM Results_CTE
WHERE RowNum >= @Offset
AND RowNum < @Offset + @Limit
The advantage here is the parameterization of the offset and limit in case you decide to change your paging options (or allow the user to do so).
Note: the @Offset
parameter should use one-based indexing for this rather than the normal zero-based indexing.
WHERE RowNum >= (@Offset + 1)

and we're good with the start condition. –
Empedocles Table
has 200k records, it will fetch all first, then apply limit ? Is this query efficient ? –
Phrenetic left join
on this query? –
Waiter 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
: requiredOFFSET
: optional number of skipped rowsNEXT
: required number of next rowsReference: https://learn.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql

Waiter select top {LIMIT HERE} * from (
select *, ROW_NUMBER() over (order by {ORDER FIELD}) as r_n_n

) xx where r_n_n >={OFFSET HERE}
A note:
This solution will only work in SQL Server 2005 or above, since this was when ROW_NUMBER()
was implemented.

Swanhilda You can use ROW_NUMBER in a Common Table Expression to achieve this.
;WITH My_CTE AS
(
SELECT
col1,
col2,
ROW_NUMBER() OVER(ORDER BY col1) AS row_number
FROM
My_Table
WHERE
<<<whatever>>>
)
SELECT
col1,
col2
FROM
My_CTE
WHERE
row_number BETWEEN @start_row AND @end_row
Specifically for SQL-SERVER you can achieve that in many different ways.For given real example we took Customer table here.
Example 1: With "SET ROWCOUNT"
SET ROWCOUNT 10
SELECT CustomerID, CompanyName from Customers
ORDER BY CompanyName
To return all rows, set ROWCOUNT to 0
SET ROWCOUNT 0
SELECT CustomerID, CompanyName from Customers
ORDER BY CompanyName
Example 2: With "ROW_NUMBER and OVER"
With Cust AS
( SELECT CustomerID, CompanyName,
ROW_NUMBER() OVER (order by CompanyName) as RowNumber
FROM Customers )
select *
from Cust
Where RowNumber Between 0 and 10
Example 3 : With "OFFSET and FETCH", But with this "ORDER BY" is mandatory
SELECT CustomerID, CompanyName FROM Customers
ORDER BY CompanyName
OFFSET 0 ROWS
FETCH NEXT 10 ROWS ONLY
Hope this helps you.
OFFSET
and FETCH
: "We recommend that you use the OFFSET and FETCH clauses instead of the TOP clause to implement a query paging solution and limit the number of rows sent to a client application." –
Isadoraisadore -- @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
FETCH NEXT 10 ROWS ONLY
I used this method: FETCH NEXT @RowsPerPage ROWS ONLY
–
Hyperextension 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.
SELECT TOP 20 id FROM table1 where id > 10 order by date OFFSET 20 rows
, you must transform it like SELECT TOP 20 * FROM (SELECT id FROM table1 where id > 10 order by date OFFSET 20 ROWS) t1
. I will edit my answer. Thanks and excuse me my English. –
Readjust Adding a slight variation on Aaronaught's solution, I typically parametrize page number (@PageNum) and page size (@PageSize). This way each page click event just sends in the requested page number along with a configurable page size:
begin
with My_CTE as
(
SELECT col1,
ROW_NUMBER() OVER(ORDER BY col1) AS row_number
FROM
My_Table
WHERE
<<<whatever>>>
)
select * from My_CTE
WHERE RowNum BETWEEN (@PageNum - 1) * (@PageSize + 1)
AND @PageNum * @PageSize
end
Another sample :
declare @limit int
declare @offset int
set @offset = 2;
set @limit = 20;
declare @count int
declare @idxini int
declare @idxfim int
select @idxfim = @offset * @limit
select @idxini = @idxfim - (@limit-1);
WITH paging AS
(
SELECT
ROW_NUMBER() OVER (order by object_id) AS rowid, *
FROM
sys.objects
)
select *
from
(select COUNT(1) as rowqtd from paging) qtd,
paging
where
rowid between @idxini and @idxfim
order by
rowid;
There is here someone telling about this feature in sql 2011, its sad they choose a little different keyword "OFFSET / FETCH" but its not standart then ok.
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
Elaborating the Somnath-Muluk's answer just use:
SELECT *
FROM table_name_here
ORDER BY (SELECT NULL AS NOORDER)
OFFSET 9 ROWS
FETCH NEXT 25 ROWS ONLY
w/o adding any extra column. Tested in SQL Server 2019, but I guess could work in older ones as well.
select top (@TakeCount) * --FETCH NEXT
from(
Select ROW_NUMBER() OVER (order by StartDate) AS rowid,*
From YourTable
)A
where Rowid>@SkipCount --OFFSET
@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
Since nobody provided this code yet:
SELECT TOP @limit f1, f2, f3...
FROM t1
WHERE c1 = v1, c2 > v2...
AND
t1.id NOT IN
(SELECT TOP @offset id
FROM t1
WHERE c1 = v1, c2 > v2...
ORDER BY o1, o2...)
ORDER BY o1, o2...
Important points:
@limit
can be replaced with number of results to retrieve,@offset
is number of results to skipwhere
and order by
clauses, and will provide incorrect results if they are out of syncorder by
is there explicitly if that's what's needed In SQL server you would use TOP together with ROW_NUMBER()
I assume that, In C# Expression/LINQ statement of skip and take generating below SQL Command
DECLARE @p0 Int = 1
DECLARE @p1 Int = 3
SELECT [t1].[Id]
FROM (
SELECT ROW_NUMBER() OVER (ORDER BY [t0].[Id]
FROM [ShoppingCart] AS [t0]
) AS [t1]
WHERE [t1].[ROW_NUMBER] BETWEEN @p0 + 1 AND @p0 + @p1
ORDER BY [t1].[ROW_NUMBER]
Since, I test more times this script more useful by 1 million records each page 100 records with pagination work faster my PC execute this script 0 sec while compare with mysql have own limit and offset about 4.5 sec to get the result.
Someone may miss understanding Row_Number() always sort by specific field. In case we need to define only row in sequence should use:
SELECT TOP {LIMIT} * FROM (
SELECT TOP {LIMIT} + {OFFSET} ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS ROW_NO,*
FROM {TABLE_NAME}
) XX WHERE ROW_NO > {OFFSET}
