消息 203，级别 16，状态 2，不是有效标识符

Question

我收到以下错误：

消息 203，级别 16，状态 2，过程 getQuestion，第 18 行
名称 'select top(1) * from tlb_Question inner join tlb_options on tlb_options.qID=tlb_Question.id and tlb_Question.qNumber=1 and tlb_Question.id not in (0,1)' 不是有效标识符

来自以下存储过程：

ALTER proc getQuestion
    @qNo bigint,
    @total bigint,
    @next nvarchar(max)
as
begin 
    declare @hisa bigint
    set @hisa=@total/3

    if(@qNo<=@total/3)
    begin
    declare @query nvarchar(max)
    set @query=('select top(1) * from tlb_Question 
        inner join tlb_options on tlb_options.qID=tlb_Question.id and tlb_Question.qNumber=1 and tlb_Question.id not in ('+cast(@next as varchar)+')')
    print @query
    execute @query
    end
end

Answer 1

请试试这个，把执行@query改成执行（@query）：

ALTER proc getQuestion
    @qNo bigint,
    @total bigint,
    @next nvarchar(max)
as

begin 
    declare @hisa bigint
    set @hisa=@total/3

    if(@qNo<=@total/3)
    begin
      declare @query nvarchar(max)
      set @query=('select top(1) * from tlb_Question 
      inner join tlb_options on tlb_options.qID=tlb_Question.id and tlb_Question.qNumber=1 and tlb_Question.id not in ('+cast(@next as varchar)+')')
      --print @query
      execute (@query)
    end
end

Answer 2

问题是execute @query。我可以在测试后确认。 @techdo 是正确的。改成

execute (@query)
