Row number within an SSRS report

I have a group in my report where I have to use row numbers within that group, I was wondering if 开发者_如何学JAVAthere is a way to display row numbers using expressions, or if I have to modify my Store procedure and include row numbers for that group.

You can use the RowNumber function in Reporting Services.

Since SQL Server 2005 this can be done with ROW_NUMBER() in the SQL code too.

Neither way is better for simple groups, but if you have dynamic groupings that you're better with the SSRS RowNumber which will calculate over the group/scope

Yes, row number is the answer. use it like this

SELECT ROW_NUMBER() OVER (PARTITION BY Col1, Col2, ... ORDER BY Col1) AS recID

Here is how to do Paging in SQL

DECLARE @startRow INT
SET @startrow = 50
;WITH cols
AS
(
    SELECT table_name, column_name,
        ROW_NUMBER() OVER(ORDER BY table_name, column_name) AS seq,
        ROW_NUMBER() OVER(ORDER BY table_name DESC, column_name desc) AS totrows
    FROM [INFORMATION_SCHEMA].columns
)
SELECT table_name, column_name, totrows + seq -1 as TotRows
FROM cols
WHERE seq BETWEEN @startRow AND @startRow + 49
ORDERBY seq
