            JOIN availablity IN _db.tbl_maint_item_availability ON n.mamd_lotno equals availablity.mia_lot_no && n. ////

这里无法显示我的验证码，请帮助我这是我的SQL查询

SELECT *
FROM   tbl_maint_activity_material_details AS _material
       JOIN tbl_maint_item_availability AS availablity
            ON  _material.mamd_maint_item_id = availablity.mia_maint_item_id
            AND _material.mamd_lotno = availablity.mia_lot_no
WHERE  _material.mamd_status = 24
