查询表达式中的Microsoft ODBC Excel驱动程序语法错误（缺少运算符）

Question

I am using XL Report Builder version 2.1.4 and trying to execute the following script but, keep getting the error "Microsoft ODBC Excel Driver Syntax Error (missing operator) in query expression".

select Bidders.*
From Bidders
where
If :Param1 = 1 Then
    Due > 0 and
    Left(Event,2) <> 12
Else
    Due = 0 and
    Left(Event,2) <> 12
End If
order by
      Name

Param1 is a user-entry parameter that can be either "0" or "1". Does anyone have any advice as to what operator I am missing?

Answer 1

The if in the query looks suspicious. Try writing the query as:

select Bidders.*
From Bidders
where (:Param1 = 1 and Due > 0 and Left(Event,2) <> 12) or
      (:Param1 <> 1 and Due = 0 and Left(Event,2) <> 12)
order by Name;

You can simplify this as:

select Bidders.*
From Bidders
where Event not like '12%' and
      ((:Param1 = 1 and Due > 0) or
       (:Param1 <> 1 and Due = 0)
      )
order by Name;
