I have a requirement in which I have to use two tables main and tmp . main is the table that have to be used always so my query is like

code>

Select * from main;

tmp 在背景中并行创建。一旦创建,我想要使用此数据库数据库。因此,我会将 tmp 重命名为,以便现在 tmp 成为正在使用的默认数据库,并且不需要修改现有的SQL查询。 / p>

tmp is created in background parallely. As soon its created, I want this DB db to be used. Hence, I will rename tmp to main so that now tmp becomes the default DB in use and the existing SQL queries need not be modified.


  1. 现在,我的问题是我可以在我重命名表格时收到类似于 table not found的错误 / li>
  1. Now, my question is can I get an error like table not found while I am renaming the tables?


推荐答案

SQLite ,也就是说,只要两个表修改在一个事务中完成,它就可以正常工作。

SQLite is transactional, i.e., as long as the two table modifications are done in a single transaction, it will work fine.
