SQL 服务器 : trying to create view inside a stored procedure

Question

我试图在存储过程中创建我的 View ，但我遇到了一个错误。

我的代码是:

    alter PROCEDURE p.Azmoon1 
    AS
    begin
       EXEC ('IF OBJECT_ID (''r.r_Sales01_Requests__Duplicates'', ''V'') IS NOT NULL
            DROP VIEW r.r_Sales01_Requests__Duplicates ;
            go
            create view r.r_Sales01_Requests__Duplicates ( 
             CompanyID
            ,Branch
            ,Year
            ,VoucherType,VoucherNumber
            ,Date_Persian
            ,Row
        ) as
        select 
             CompanyID
            ,Branch
            ,Year
            ,VoucherType,VoucherNumber
            ,Date_Persian
            ,Row
        from t_SalesRequests
        group by CompanyID,Branch,Year,VoucherType,VoucherNumber,Date_Persian,Row
        having count(*)>1

        go

    ')
    end

当我像下面这样调用我的程序时:

execute p.Azmoon1 

我遇到了这些错误:

Incorrect syntax near 'go'
'CREATE VIEW' must be the first statement in a query batch.
Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).

正如@mark_s 正确提到的那样删除“Go”，它不是可在 EXEC 中执行的 SQL 关键字。

我创建了以下程序来修改 View ，就像您所做的那样。除了不使用“Go”之外，我使用了两个单独的 EXEC 语句。

create procedure [dbo].[CreateInvoiceView]
as 
begin
    Exec ('If object_ID(''invoices'',''V'') is not null 
            drop view invoices;')

    Exec ('
        create view [dbo].[Invoices] AS
           SELECT Orders.ShipName as SHIP_Name, Orders.ShipAddress, Orders.ShipCity, Orders.ShipRegion, Orders.ShipPostalCode,Orders.ShipCountry, Orders.CustomerID, Customers.CompanyName AS CustomerName, Customers.Address, Customers.City, Customers.Region, Customers.PostalCode, Customers.Country, (FirstName + '' '' + LastName) AS Salesperson, Orders.OrderID, Orders.OrderDate, Orders.RequiredDate, Orders.ShippedDate, Shippers.CompanyName As ShipperName
            FROM    Shippers INNER JOIN 
                    (Products INNER JOIN 
                       (
                       (Employees INNER JOIN 
                       (Customers INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID) 
                              ON Employees.EmployeeID = Orders.EmployeeID) 
                              INNER JOIN "Order Details" ON Orders.OrderID = "Order Details".OrderID) 
                              ON Products.ProductID = "Order Details".ProductID) 
                              ON Shippers.ShipperID = Orders.ShipVia

    ')
end
