Question

我有一张桌子。它有超过100行并且正在增加。我想得到这样的行：

1  - row (not needed 2,3,4,5,6,7. rows)
8  - row  
15 - row
22 - row
29 - row

注意：在MSSQL 2008 R2上

Answer 1

您可以使用ROW_NUMBER和%，f.e。使用common-table-expression：

WITH CTE AS
(
  SELECT t.*, RN= ROW_NUMBER() OVER (Order By OrderColumn ASC)
  FROM dbo.TableName t
)
SELECT * FROM CTE WHERE RN % 7 = 1

Answer 2

- 它有助于你

CREATE TABLE ##Numeric (Id INT)

DECLARE @Value INT = 1

WHILE (@Value <= 100)
BEGIN
    INSERT INTO ##Numeric
    SELECT @Value

    SET @Value = @Value + 1
END

SELECT *
FROM ##Numeric
WHERE ID % 7 = 1

如何只选择表格中的每第n行？
