如何使用变量在SQL RAISERROR

Question

我试图表现出RAISERROR @MaxAmount我int变量和@MinAmount

Raiserror('Total Amount should be less than %s and Greater than %s',16,1,@MaxAmount,@MinAmount) 

但是我得到错误：

Must declare the scalar variable "@MaxAmount".

Answer 1

%s用于varchar和您的变量的类型int因此你需要尝试使用正确的格式说明即，%d

DECLARE @MaxAmount int = 16; 
DECLARE @minAmount int = 1; 
Raiserror('Total Amount should be less than %d and Greater than %d',@MaxAmount,@MinAmount) 

检查RAISEERROR了解详情。

Answer 2

我觉得你这样试试：

DECLARE @MaxAmount int = 16; 
DECLARE @MinAmount int = 1; 

Raiserror('Total Amount should be less than %d and Greater than %d',@MaxAmount,@MinAmount)

您需要使用％I作为整数，如前所述，在使用前声明变量。

declare @MaxAmount int, @MinAmount int 
select @MaxAmount = 50, @MinAmount = 5 
Raiserror('Total Amount should be less than %i and Greater than %i',16,1,@MaxAmount,@MinAmount)
