收到錯誤的參數傳遞給存儲過程

Question

我有以下存儲過程：

ALTER PROCEDURE sp_InsertHashBinMinHash 
    @Id INT, 
    @HashBin BIGINT, 
    @HashTable INT, 
    @SubFingerprintId BIGINT, 
    @Seqno INT 
AS 

INSERT INTO HashBinsMinHash (
    HashBin, 
    HashTable, 
    Seqno, 
    SubFingerprintId 
    ) OUTPUT inserted.Id 
VALUES 
(
    @HashBin, @HashTable, @Seqno, @SubFingerprintId 
); 

當我運行程序我收到以下錯誤：

procedure or function sp_insertHashBin expects parameter @Seqno which was not supplied

但我將4個參數傳遞給過程

Answer 1

存在您的問題：sp_InsertHashBinMinHash需要5個參數（Id,HashBin,HashTable，SubFingerprintId和Seqno）。你只能用4來調用它。所以缺少一個。

Answer 2

我將它改寫爲

ALTER PROCEDURE sp_InsertHashBinMinHash 
    @HashBin BIGINT, 
    @HashTable INT, 
    @SubFingerprintId BIGINT, 
    @Seqno INT, 
    @Id INT OUT 
AS 
BEGIN 
INSERT INTO HashBinsMinHash (
    HashBin, 
    HashTable, 
    Seqno, 
    SubFingerprintId 
    ) 
VALUES 
(
    @HashBin, @HashTable, @Seqno, @SubFingerprintId 
); 

set @Id = SCOPE_IDENTITY(); 
select @id 
END 

而且，從C＃將值傳遞給你的程序，添加參數@Id用正確的方向屬性。
