Tenho uma consulta que conta as datas de casamento dos membros no banco de dados.
SELECT
SUM(NumberOfBrides) AS [Wedding Count]
, DATEPART( wk, WeddingDate) AS [Week Number]
, DATEPART( year, WeddingDate) AS [Year]
FROM MemberWeddingDates
GROUP BY DATEPART(year, WeddingDate), DATEPART(wk, WeddingDate)
ORDER BY SUM(NumberOfBrides) DESC
Como faço para saber quando o início e o final de cada semana representados no conjunto de resultados?
SELECT
SUM(NumberOfBrides) AS [Wedding Count]
, DATEPART(wk, WeddingDate) AS [Week Number]
, DATEPART(year, WeddingDate) AS [Year]
, ??? AS WeekStart
, ??? AS WeekEnd
FROM MemberWeddingDates
GROUP BY DATEPART(year, WeddingDate), DATEPART(wk, WeddingDate)
ORDER BY SUM(NumberOfBrides) DESC
DATEFIRST
para qualquer coisa diferente de 7 quebra isso.
