在mysql中創建臨時表

Question

是不是可以在臨時表裏面使用臨時表？ 當我使用

CREATE TEMPORARY TABLE bo_attribute_description_group_temp (
    SELECT id 
    FROM bo_attribute_description_group 
    WHERE display_name IN ('backoffice.attr.group.services', 'backoffice.attr.group.eyecatchergroup') 
); 

select * from bo_attribute_description_group_temp; 

CREATE TEMPORARY TABLE bo_attribute_description_temp (
    SELECT id 
    FROM bo_attribute_description 
    WHERE group_id IN (bo_attribute_description_group_temp) 
); 

，但它給了我

Error Code: 1054. Unknown column 'bo_attribute_description_group_temp' in 'where clause' 0.000 sec 

爲什麼???

是的，你可以。您必須在第二個創建表子查詢中使用select子句：

CREATE TEMPORARY TABLE bo_attribute_description_group_temp (SELECT id 
                 FROM bo_attribute_description_group 
                 WHERE display_name IN ('backoffice.attr.group.services', 'backoffice.attr.group.eyecatchergroup')); 

select * from bo_attribute_description_group_temp; 

CREATE TEMPORARY TABLE bo_attribute_description_temp (SELECT id 
                FROM bo_attribute_description 
                WHERE group_id IN (select id from bo_attribute_description_group_temp));
