我在我的存储过程中更改了模式，我遇到了特定临时表的错误：
SQL71502：过程：[LS1]。[Report_ChildPAXData_Summary]有一个 未解决的对象#baggage
的引用
它指向的行在下面：
IF OBJECT_ID('tempdb..#baggage') IS NOT NULL
DROP TABLE #baggage
这是声明问题吗？只是想知道如何解决这个错误，因为我会在其他存储过程中遇到更多临时表。
更新：如评论中所述，发布了整个存储过程：

答案 0 :(得分：0)
您可以在临时表上使用表变量。所以你不需要关心删除表，因为它是一个变量：
DECLARE @tempPersonDetail table
(
PKCreateDate datetime,
Flight_DepartureDateTime DATETIME,
FlightNumber NVARCHAR(50) ,
Dep_AirportCode CHAR(3),
Arr_AirportCode CHAR(3),
Person_PersonTypeId INT,
person_Name varchar(101), --Forename varchar(50) + '\' char + surname varchar(50)
TDI_DOB DATETIME,
Person_DOB DATETIME,
TDI_Yr INT,
Per_yr INT,
Person_Age INT,
Person_TitleID INT,
adult BIT NULL,
child BIT NULL,
infant BIT NULL,
female BIT NULL,
male BIT NULL,
)
