sql - 无效的对象名称 - 存储过程

Question

我正在通过 SSMS 在 SQL Server 中创建一个存储过程。

我已经编写了下面的存储过程，但是当我单击执行时，出现错误:

消息 208，级别 16，状态 6，程序 NewQuestion，第 11 行对象名称“hgomez.NewQuestion”无效。

该表的所有权是正确的。 (hgomez.问题)

USE [devworks_oscar]
GO
/****** Object:  StoredProcedure [hgomez].[NewQuestion]    Script Date: 10/23/2011 23:55:08 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [hgomez].[NewQuestion]
    (
    @QUESTIONNAME nvarchar(50),
    @QUESTION_ID int OUTPUT
    )

AS
    /* SET NOCOUNT ON */
    INSERT INTO [Questions] (QuestionText) VALUES (@QUESTIONNAME)
    SET @QUESTION_ID = SCOPE_IDENTITY();
    RETURN

提前致谢

我喜欢总是在 CREATE 语句前明确检查是否存在，如果找到则删除。

IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_NAME = 'NewQuestion' AND ROUTINE_SCHEMA = 'hgomez')
BEGIN
    DROP PROCEDURE hgomez.NewQuestion
END
GO

-- this is always a CREATE
CREATE PROCEDURE [hgomez].[NewQuestion]
    (
    @QUESTIONNAME nvarchar(50),
    @QUESTION_ID int OUTPUT
    )

AS
    /* SET NOCOUNT ON */
    INSERT INTO [Questions] (QuestionText) VALUES (@QUESTIONNAME)
    SET @QUESTION_ID = SCOPE_IDENTITY();
    RETURN

这在权限方面可能会有点麻烦，因此其他人使用一种方法，他们创建一个 stub 方法只是为了立即ALTER它。

IF NOT EXISTS (SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_NAME = 'NewQuestion' AND ROUTINE_SCHEMA = 'hgomez')
BEGIN
    EXEC ('CREATE PROCEDURE hgomez.NewQuestion AS SELECT ''stub version, to be replaced''')
END
GO

-- This is always ALTER
ALTER PROCEDURE [hgomez].[NewQuestion]
    (
    @QUESTIONNAME nvarchar(50),
    @QUESTION_ID int OUTPUT
    )

AS
    /* SET NOCOUNT ON */
    INSERT INTO [Questions] (QuestionText) VALUES (@QUESTIONNAME)
    SET @QUESTION_ID = SCOPE_IDENTITY();
    RETURN
