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)

之后又说了以下

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。

所以起初我只是改变了第二行，所以它说了

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

但是这给了我一个密码列的错误，所以我把它改成了：

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。

Answer 1

您必须在名称前使用@符号声明变量。所以这是正确的：

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

这是不正确的：

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

我认为问题在于您的变量声明。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

如果[密码]是TempUsers中的一列，则可能意味着这一点。

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)

nvarchar不是可识别的游标选项
