sql - SQL语法错误，语法不正确？

Question

每次运行查询时，都会收到语法错误。问题是，当我在发生错误的行中运行代码时，该代码运行了该部分，所以我不知道为什么会收到以下错误消息。

Msg 102, Level 15, State 1, Line 1  
Incorrect syntax near ')'.  
Msg 102, Level 15, State 1, Line 1  
Incorrect syntax near ')'.

我的代码:

declare @Source_Database_Name AS varchar(255) = 'dbo.Production2';
declare @Destination_Database_Name AS varchar(255) = 'c365online_script1';

declare @Company_Id int = 1 --declare a companyid 

CREATE TABLE #CompanyID1 (ID bigint)

INSERT INTO #CompanyID1(ID)
VALUES('1')

--FIRST CURSOR LOOP THROUGH THIS TABLE
CREATE TABLE #TableList (


    processorder int,
    tablename NVARCHAR(100)
    )
INSERT INTO #TableList (processorder, tablename )
VALUES
(1, 'tCompany');

DECLARE @firstLoop BIT
--SET @firstLoop = true
DECLARE @Counter INT  -- counting variable

----------- Cursor specific code starts here ------------

这些行的末尾看起来像是多余的括号:

EXEC('INSERT'  + @Destination_Database_Name + '.dbo.' + @tablename + ' SELECT * FROM ' + @Source_Database_Name + '.dbo.' + @tablename + ' WHERE ' + @Source_Database_Name + '.dbo.' + @tablename + '.CompanyID = ' + @Company_Id + ')')   

EXEC('INSERT ' + @Destination_Database_Name + '.dbo.' + @tablename + ' SELECT * FROM ' + @Source_Database_Name + '.dbo.' + @tablename + ')')

引号中有一个右括号，但没有与之对应的左括号。
