sql - 存储过程 : There is already an object named '#columntable' in the database

Question

请看下面的代码:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE Test
AS
BEGIN
    begin
    select * into #dbreviews from dbreviews
    end

    drop table #dbreviews

    begin
    select * into #dbreviews from dbreviews
    end

END
GO

我得到的错误是:

There is already an object named '#dbreviews' in the database.

这样的问题:There is already an object named '#columntable' in the database告诉我这应该是可能的。

Answer 1

根据 SQL Server 规范，这是不允许的。请引用documentation .

If more than one temporary table is created inside a single stored procedure or batch, they must have different names.

您正在创建两个具有相同名称 #dbreviews 的临时表。这是不允许的。
