Oracle - Where子句中的Case

Question

我正在尝试在Oracle数据库中执行查询.该查询在where子句中有case构造.

where
    sale.op = 2 and
        case when (:stat = -11) then (sale.type_id = 27 or sale.type_id = 28 or sale.type_id = 29)
    else
    (sale.type_id = 27)
    end

但是我收到以下错误:

ORA-00907:缺少右括号.

在Derby SQL中这是有效的.有人可以帮帮我吗？谢谢.

Answer 1

where sale.op = 2 
and (     (:stat = -11 and sale.type_id in (27, 28, 29))
      or  (:stat <> -11 and sale.type_id = 27)
    )
