Make sure that the data table is actually deleted, not just that the data is cleared. You can check whether the data table exists in the database through the command line or phpMyAdmin.

       字段名1 类型1 约束1,
       字段名2 类型2 约束2,
       ...
   );</code>

2. Import data: Get the deletion time from the log file, and extract the data before this time point through SQL query:

   <code class="sql">SELECT * FROM deleted_table_name WHERE updatetime < '删除时间';</code>

3. Insert into the new data table: Insert the queried data into the newly created data table:

   <code class="sql">INSERT INTO new_table_name (字段名1, 字段名2, ...)
   SELECT 字段名1, 字段名2, ...
   FROM deleted_table_name
   WHERE updatetime < '删除时间';</code>
