我有一个存储过程，如果表存在则删除它，然后它重新创建表并用相关数据填充它，我的一个朋友有大约相同的代码，唯一真正的区别在于表的列标题。
作为说明，这是我的外观（不是真的，只是一个表示）。
+----+-----+-----+--------+
| ID | Foo | Bar | Number |
+----+-----+-----+--------+
| 1 | x | x | 0 |
| 2 | x | x | 1 |
+----+-----+-----+--------+
这就是他的样子
+----+--------+--------+-----+--------+
| ID | BarFoo | FooBar | Num | Suffix |
+----+--------+--------+-----+--------+
| 1 | x | x | 0 | a |
| 2 | x | x | 1 | b |
+----+--------+--------+-----+--------+
同样，这些只是情况的代表。
由于这是一项学校作业，老师将创建和执行两个 SP，但是在使用另一个 SP 后创建 SP 时，我收到此错误：
消息 207，级别 16，状态 1，过程 XYZ，第 59 行
无效的列名称“Foo”。消息 213，级别 16，状态 1，过程 XYZ，第 61 行
列名称或提供的值的数量与表定义不匹配。
然而，在这两个存储过程的开始，我们有这个：
CREATE PROCEDURE XYZ
AS
BEGIN
IF EXISTS (SELECT name
FROM sysobjects
WHERE name = 'TABLENAME'
AND xtype = 'u')
DROP TABLE TABLENAME;
据我了解，这应该删除整个表？包括表/列定义和数据？
到目前为止，我发现的唯一解决方法是DROP TABLE在创建存储过程之前单独执行，这对我们不起作用，因为它确实必须在存储过程中。
帮助将不胜感激:)
编辑：这是我的实际代码，除了注释，这正是它在我的脚本中的样子（不包括它后面的其他代码）。
IF EXISTS (SELECT name
FROM sysobjects
WHERE name = 'BerekenStatistiek'
AND xtype = 'p')
DROP PROCEDURE BerekenStatistiek;
GO
CREATE PROCEDURE BerekenStatistiek
@jaar INT=0
AS
BEGIN
IF EXISTS (SELECT name
FROM sysobjects
WHERE name = 'Statistiek'
AND xtype = 'u')
DROP TABLE Statistiek;
DECLARE @year AS NVARCHAR (4);
SET @year = CONVERT (NVARCHAR (4), @jaar);
SELECT *,
CAST (Kost - Korting + Freight AS MONEY) AS Netto,
'' AS Richting
INTO Statistiek
FROM (SELECT O.Kwartaal,
CAST (SUM(O.Kost) AS MONEY) AS Kost,
CAST (SUM(O.Korting) AS MONEY) AS Korting,
CAST (SUM(O.Freight) AS MONEY) AS Freight

END AS 'Kwartaal',

Round((UnitPrice * Quantity) * Discount, 2) AS Korting,

ALTER TABLE Statistiek ALTER COLUMN Kwartaal INT NOT NULL;
ALTER TABLE Statistiek ALTER COLUMN Richting NVARCHAR (8);
ALTER TABLE Statistiek

这是他的代码（在变量中插入值只是为了便于阅读（他的代码有点笨重）：
