Sql If语句语法错误

我正在尝试创建一个If语句，如果商品超过100K或公司名为CGELENA或CGFEDUN，则该语句将查找并列出以下值，如果没有，则检查商品类型是否列在下面

If (ord_miscqty >='100000' OR m.cmp_id in('CGELENA','CGFEDUN')

在else语句中，必须使用选择

Else If
Select f.cmd_code in ('COPSUL',...
....

缺少

）

第1行中的Start您使用什么RDBMS？其中一些可能不支持常规查询上下文中的

IF/ELSE

控制结构，而只允许在存储过程/函数中使用它们。

[]

括号表示可能是MS SQL Server或Access。哦，我的上帝，你写了这样一个怪物，却找不到缺少的括号？？
