Answer 1

试试这个Sample脚本，我在程序中使用了样例表，通过变量的输入值将是别名列名

CREATE PROCEDURE Usp_procedure (@var int)
AS
Begin
DECLARE @Sql nvarchar(max)

SET @Sql='
SELECT EmployementStatus AS '+ QUOTENAME(CAST(@var AS VARCHAr(10)))+'
 from [dbo].[EmployeeInfo]'
 --Print @Sql
 EXEC (@Sql)

END


EXEC Usp_procedure @var=1

结果

您可以使用Dynamic SQL实现此目的。像这样的东西

var linePoints = new List<Vector2>(){new Vector2(20, 30), new Vector2(200, 300)}; // C#
    VectorLine myLine = new VectorLine("Line", linePoints, 2.0f);
    myLine.Draw();
