nvarchar不是可识别的游标选项

Question

我正在运行一些sql,它从临时表中获取信息并将其放入永久表中.我是从3年前写的一步一步的指南中得到的,写这篇文章的人早就不见了.它声明在这里使用这个sql.

declare @Password nvarchar(100); 
set @Password ='rewards';
if not exists(select 1 from sys.openkeys where key_name = 'Sym_UserPassData' 
and database_name = db_name())  OPEN SYMMETRIC KEY Sym_UserPassData DECRYPTION BY
CERTIFICATE UserPassTables with password='asbpass71509new';
INSERT INTO [User] (Username, [Password], AllowChange, ForceChange, FullName,
SalesRep, OpenLink, UserProfileID, LastUpdatedBy,UserEmail) 
(SELECT Username,EncryptByKey(Key_GUID('Sym_UserPassData'),@Password), 
AllowChange, ForceChange, FullName, SalesRep, [OpenLink ], UserProfileID,    
LastUpdateBy, UserEmail FROM TempUsers)

之后它说了以下内容

如果每行的密码都是唯一的,请设置@Password ='密码'; 关闭并用[密码]替换@Password.

所以起初我只是更改了第二行,所以它说

declare @Password nvarchar(100);
set [Password]
...

但是这给了我一个密码列的错误,所以我把它改成:

declare [Password] nvarchar(100); 
set [Password]
if not exists(select 1 from sys.openkeys where key_name = 'Sym_UserPassData' 
and database_name = db_name())  OPEN SYMMETRIC KEY Sym_UserPassData DECRYPTION BY
CERTIFICATE UserPassTables with password='asbpass71509new';
INSERT INTO [User] (Username, [Password], AllowChange, ForceChange, FullName,
SalesRep, OpenLink, UserProfileID, LastUpdatedBy,UserEmail) 
(SELECT Username,EncryptByKey(Key_GUID('Sym_UserPassData'),[Password]), 
AllowChange, ForceChange, FullName, SalesRep, [OpenLink ], UserProfileID,    
LastUpdateBy, UserEmail FROM TempUsers)

这就是给我错误的原因:

 nvarchar is not a recognized cursor option 

有谁知道我错过了什么？如果我能提供任何其他信息,我会尽我所能.

感谢能够提供帮助的任何人.

您必须@在名称前面使用符号声明变量.所以这是正确的:

declare @Password nvarchar(100); 
set @Password ='rewards';

这不正确:

declare [Password] nvarchar(100); 
set [Password] ='rewards';

我认为问题在于你的变量声明.请参阅此文章:http://www.databasejournal.com/features/mssql/article.php/3087431/T-SQL-Programming-Part-1---Defining-Variables-and-IFELSE-logic.htm
