T-SQL强制嵌套

Question

我正在尝试将此结果转换为整数？

SELECT 
    CAST(7 AS DECIMAL (18,8)) * CAST(365 AS DECIMAL (18,8)) 
    / CAST(12 AS DECIMAL (18,8)) / CAST(7 AS DECIMAL (18,8))

结果是30.416666

但是我想把它重新归结为一个整数，即30

我知道可以通过铸造整个批次来完成，但无法正确嵌套？

Answer 1

您只需要将最终结果转换为INT

SELECT cast(CAST(7 AS DECIMAL(18, 8)) * CAST(365 AS DECIMAL(18, 8)) 
    / CAST(12 AS DECIMAL(18, 8)) / CAST(7 AS DECIMAL(18, 8)) AS INT)
