收到错误的参数传递给存储过程

Question

我有以下存储过程：

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 
); 

当我运行程序我收到以下错误：

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

但我将4个参数传递给过程

Answer 1

存在您的问题：sp_InsertHashBinMinHash需要5个参数（Id,HashBin,HashTable，SubFingerprintId和Seqno）。你只能用4来调用它。所以缺少一个。

Answer 2

我将它改写为

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，从C＃将值传递给你的程序，添加参数@Id用正确的方向属性。
