如何使用變量在SQL RAISERROR

Question

我試圖表現出RAISERROR @MaxAmount我int變量和@MinAmount

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

但是我得到錯誤：

Must declare the scalar variable "@MaxAmount".

Answer 1

%s用於varchar和您的變量的類型int因此你需要嘗試使用正確的格式說明即，%d

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

檢查RAISEERROR瞭解詳情。

Answer 2

我覺得你這樣試試：

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作爲整數，如前所述，在使用前聲明變量。

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)
