在预期条件接近“，”的上下文中指定的非布尔类型的表达式

Question

当我运行在 SQL 服务器上执行以下查询时，它可以很好地处理单个值或多个值。但是当我尝试在 SSRS 数据集上执行相同的操作时，它会为多个值抛出错误。

ERROR: SSRS: An expression of non boolean type specified in a context where a condition is expected near ','. Incorrect syntax near the keyword 'ELSE'.

单值工作正常。不确定是什么问题，或者是否有任何其他方式可以编写此查询。

DECLARE @UserTeam VARCHAR(max) = 'Team1,Team2,Team3,Team4,Team5,Team6,'''

-- Values can inculdes null. if user select blank and Team1,Team2 we need to pull data which is null, Team1, Team2 
IF Object_id('tempdb.dbo.#Team', 'U') IS NOT NULL
  DROP TABLE #team;

SELECT item AS Team
INTO   #team
FROM   dbo.FNSPLIT(@UserTeam, ',')

IF @UserTeam = ''
  BEGIN
      SELECT U.username,
             T.teamcode
      FROM   [User].vwuser u
             LEFT JOIN[User].userteam UT
                    ON U.userid = UT.userid
             LEFT JOIN [User].team AS T
                    ON T.teamid = Ut.teamid
      WHERE  T.teamcode IS NULL
      ORDER  BY U.username
  END
ELSE
  BEGIN
      SELECT U.username,
             T.teamcode
      FROM   [User].vwuser u
             LEFT JOIN [User].userteam UT
                    ON U.userid = UT.userid
             LEFT JOIN [User].team AS T
                    ON T.teamid = Ut.teamid
             JOIN #team tm
               ON T.teamcode = tm.team
      WHERE  ( U.username NOT LIKE '%System%' )
      ORDER  BY U.username
  END

Answer 1

可以执行下一句，测试函数fnSplit:

声明 @UserTeam VARCHAR(MAX) = 'Team1,Team2,Team3,Team4,Team5,Team6,'''

SELECT item AS Team FROM dbo.fnSplit(@UserTeam,',')

如果上述功能正常运行，您将看到七行：

团队 1
团队 2
Team3
Team4
Team5
Team6
'（单引号）

Answer 2

我可以弄清楚是什么问题了。这是因为 UserTeam 参数不接受多项选择。为了解决我添加了下面的表达式。

=JOIN(Parameters!UserTeam.Value,",")

数据集属性 -> 参数 -> @UserTeam -> 添加表达式。基本上它将以逗号分隔值分隔，函数 split dbo.fnSplit(@UserTeam, ',') 将转换为 table.

此外，我还以更好的方式更改了没有 IF 条件的查询

SELECT U.userName, T.teamCode 
FROM [User].vwUser u
   left join [User].UserTeam UT  ON U.userId = UT.userId 
   left join [User].Team AS T ON T.teamId = Ut.teamId 
WHERE        
   U.userName NOT LIKE '%System%'
   AND ISNULL(T.teamCode,'')  IN (SELECT ISNULL(item,'') FROM dbo.fnSplit(@UserTeam,','))
ORDER BY U.userName
