Question

我有一个MySQL查询，它基本上获取了填充新表的所有信息，但我不知道该如何进行：

创建新表但如果已存在，则删除现有表并再次创建
将所有数据放入新表格

并且希望有人能帮助我或指出我正确的方向。

这是我现有的SQL，以防它有帮助（放在PHP文件中）：

) AS table2              
ORDER BY         
 GroupLevel,
 ChildNode DESC,
 ParentNode DESC

我尝试使用格式：

SELECT *
INTO new_table_name
FROM [query]

在上面的查询中，但它只显示Invalid query: Undeclared variable: new_table_name

Answer 1

尝试INSERT INTO...SELECT声明

INSERT INTO newTable (ChildNode, NoOfFails, GroupLevel, ImageNamePrefix)
SELECT ... -- paste your SELECT STATEMENT HERE (the one you posted)

从MySQL Doc，服务器不支持SELECT INTO。

Read About This
的 INSERT INTO...SELECT

将查询结果放入新表中
