Question

我有这样的查询：

select 
    F_ExhibitionCode,
    F_ExhibitorCode 
from 
    T_ExhibitorLocation 
where 
    F_ExhibitorCode in (
        select 
            F_Exhibitor_Code 
        from 
            T_Exhibitor 
        where 
            F_Exhibitor_Name  LIKE '%''%')

我还有两个表，一个是* T_Exhibition *，另一个是“T_Exhibitor，F_exhibiton名称来自T_Exhibition 而F_ExhibitorCode来自T_Exhibitor，
最终结果我需要这样： F_Exhibitonnaem，F_Exhibition代码，F_exibitorname，F参展商代码。

Answer 1

假设我理解你的表结构，我会建议这些内容：

SELECT EL.F_ExhibitionCode, EL.F_ExhibitorCode, E.F_exhibiton_name
FROM T_ExhibitorLocation EL
INNER JOIN T_Exhibitor E ON(EL.F_ExhibitorCode = E.F_ExhibitorCode)
WHERE E.F_Exhibitor_Name LIKE '%''%'

使用子查询时从另一个表中获取名称
