How to
1: The SQL command ends with a semicolon (;) and two minus signs (;) represent comments.
2: Create film (name, length)

4: index creation speeds up create index
I have been entangled in this problem for a long time. I have thought a lot of ideas before:
1) record in webdb;
2) Adopt asynchronous thread record;
3) Use JS like cnzz or Google;
4) That's all you remember.
However, all of them were
Today, due to SQLite paging, it took a few hours!
SQLite starts from the third page and only displays data on the second page!

SQLite is a small embedded relational database that can be embedded into almost all programming languages, especially C, C ++, PHP, Perl, etc. This section describes how to use Perl to connect to and operate the SQLite database.

When developing a system that processes a large amount of data and has extremely powerful randomness (such as network data), we will always face the problem of positive data verification,
Especially when these systems are not based on databases but
As we learn more deeply, the content of these days has become more and more exciting. as an application developer, We have to operate data. android provides us with many types of data storage and reading.This method reduces the development cycle and
Even for network applications, local data storage needs to be considered in case of disconnection. Before SQLite appeared, when the data volume was large, we always used ACCESS. If the data volume was small, the file was stored. ACCESS does not
SQLite Database
SQLite is an open-source embedded relational database, which was developed by D. richard hipp is released, which reduces the overhead of Application Data Management. SQLite is portable, easy to use, small, efficient, and reliable.
A small app is written, and data needs to be stored in sqlite. Follow the instructions in this document to create a database file as follows:
db_aimu = SQLiteDatabase.openOrCreateDatabase("test.db", null);

The database size is limited to 2 TB (241 bytes). This is a theoretical limitation. In fact, you should limit the size of the SQLite database to less than GB to avoid running performance problems. If
