SQLite数据库字段类型

都知道Android中数据保存之一就是使用了sqlLite，所以经常创建表需要涉及到数据库字段。

sqlLite中包含5中字段，根据下面的介绍对于想inte，应该会根据值自动设置长度存储。具体待学习

Each value stored in an SQLite database (or manipulated by the database engine) has one of the following storage classes:

• NULL. The value is a NULL value.

• INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value.

• REAL. The value is a floating point value, stored as an 8-byte IEEE floating point number.

• TEXT. The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE).

• BLOB. The value is a blob of data, stored exactly as it was input.
