Question

我有以下查询：

DECLARE @userrole as VARCHAR(100)

SELECT @userrole = UserRole 
FROM UserMenuRights 
WHERE idAdmin = 36

Execute('Select idRole,RoleName from UserRoles WHERE idRole IN ('+@userrole+')')

我收到错误：

Msg 102，Level 15，State 1，Line 1
'）'附近的语法不正确。

我已检查第一行DECLARE @userrole as VARCHAR(100)似乎没有语法问题。

同时检查最后一行：

Execute('Select idRole,RoleName from UserRoles WHERE idRole IN ('+@userrole+')')

也似乎是正确的字符串附件。

我在哪里犯了错误？

请帮帮我。

Answer 1

试试这个，你需要添加单引号

DECLARE @userrole as VARCHAR(100)
SELECT @userrole =UserRole FROM UserMenuRights WHERE idAdmin =36
Execute('Select idRole,RoleName from UserRoles WHERE idRole IN ('''+@userrole+''')')

或者你像这样构建它

SELECT  idRole
        ,RoleName
FROM    UserRoles
WHERE   idRole IN (
            SELECT UserRole FROM UserMenuRights WHERE idAdmin =36
            )

Answer 2

DECLARE @userrole as VARCHAR(100)
SELECT @userrole =UserRole FROM UserMenuRights WHERE idAdmin =36

-- Use sp_executesql instead
DECLARE @Statement NVARCHAR(MAX)
SET @Statement = N'SELECT idRole, RoleName FROM UserRoles WHERE idRole = @UserRole'

EXEC sp_executesql @statement, N'@UserRole varchar(100)', @UserRole

“＃”;＆＃39;附近的语法不正确。在sql的变量声明中
