Use this: SELECT *, ROW_NUMBER () OVER (ORDER BY id) AS RowNum FROM (SELECT DISTINCT id FROM table WHERE fid = 64) Base. and put the output of a query as the input of another. Using CTE: ; WITH Base AS ( SELECT DISTINCT id FROM table WHERE fid = 64 ) SELECT *, ROW_NUMBER () OVER (ORDER BY id) AS RowNum FROM Base.
SELECT ROW_NUMBER() OVER(ORDER BY SomeColumn) AS RowNr ,tbl.* FROM (SELECT DISTINCT ….) AS tbl ROW_NUMBER() will generate a number for each row. DISTINCT is looking for identical rows. But – as they have a running number each, they are not identical…
10/9/2013 · SELECT DISTINCT v1, v2, v3, DENSE_RANK() OVER (window) row_number FROM t WINDOW window AS (ORDER BY v1, v2, v3) If any of v1, v2, v3 are other ranking functions or aggregate functions, or non-deterministic expressions, etc.
the above trick won’t work.
Summary: in this tutorial, you will learn how to use the SQL Server ROW_ NUMBER() function to assign a sequential integer to each row of a result set.. Introduction to SQL Server ROW_ NUMBER() function. The ROW_NUMBER() is a window function that assigns a sequential integer to each row within the partition of a result set. The row number starts with 1 for the first row in each partition.
This is, in a way, an extension to Lennart’s solution, but it is so ugly that I dare not suggest it as an edit.The goal here is to get the results without a derived table. There may never be the need for that, and combined with the ugliness of the query the whole endeavour may seem like a wasted effort.
To add a row number column in front of each row, add a column with the ROW_NUMBER function, in this case named Row#. You must move the ORDER BY clause up to the OVER clause. SELECT ROW_NUMBER() OVER (ORDER BY name ASC) AS Row#, name, recovery_model_desc FROM sys.databases WHERE database_id < 5; Here is the result set.Alternative interpretation of the original query (results in updating more rows): WITH UpdateSet AS ( SELECT AgentID, RuleID, Received, Calc = SUM(CASE WHEN Passed = 1 AND rn = 1 THEN 1 ELSE 0 END) OVER ( PARTITION BY AgentID, RuleID) FROM ( SELECT AgentID, RuleID, Received, Passed, rn = ROW_NUMBER() OVER ( PARTITION BY AgentID, RuleID, Passed, GroupID ORDER BY …
