Question

如何从范围为55 - 42000的column_a中选择表格。

注意：column_a的数据类型位于nvarchar

我试过这样，但没有运气

SELECT 
   SoftwareName, SoftwareImageTeaser, SoftwarePrice, SoftwareDescription
FROM 
   View_Software_Listing_With_Category 
WHERE 
   (SoftwarePrice >= '55' AND SoftwarePrice <= '42000')

Answer 1

SELECT SoftwareName,SoftwareImageTeaser,SoftwarePrice,SoftwareDescription
FROM View_Software_Listing_With_Category 
WHERE (CAST(CAST(SoftwarePrice AS FLOAT) AS INT) BETWEEN 55 AND 42000

Answer 2

试试这个，因为你的SoftwarePrice列是nvarchar，你需要在整数中转换它以与整数值进行比较。然后，您可以使用between子句来过滤记录。

SELECT SoftwareName,SoftwareImageTeaser,SoftwarePrice,SoftwareDescription
FROM View_Software_Listing_With_Category 
WHERE Cast(SoftwarePrice as Int) between 55 AND 42000

SQL选择nvarchar列的范围
