When using sqlite3 to create database tables, note that the sqlite3 Database

Note the following when using sqlite3 to create a database table:

1. Cannot use pure numbers

2. It cannot contain "-", "@", and other characters. Cannot start with a number.

1. The following information is output by log:

DB Error: 1 "unrecognized token:" 47464636265757265763393573649 ""

DB Query: insert into 47464636265757265763393573649 (role, number, name) values (?,?,?)

In fact, I want to use 47464636265757265763393573649 to indicate that it is actually not feasible. Cannot be a pure number

Ii. log below. I want to use the date as the table name.

DB Error: 1 "near" 2014 ": syntax error"

DB Query: insert into 2014-11-01-(role, number, name) values (?,?,?)

It means "-" is not acceptable.

III. The following log, I want to use uri as the table name:

DB Error: 1 "near": chat0015453d2792ef ": syntax error"

DB Query: insert into sip: chat0015453d2792ef@chat.xxx.com (role, number, name) values (?,?,?)

Note @ is also not acceptable

It is possible that the underlying layer of sqlite3 program the table name as a class name. Because the naming rules of tables are the same as those of variables.

Advice: I used sqlite3 to create a database and added some data to generate a db file.

You can create a database as a 64-bit operating system. When you open the database using SQLite expert personal 3, the database is opened based on a 32-bit operating system. Therefore, the system reports incompatibility!
