sqlite 获取数据库所有表名和字段名

转自：http://blog.sina.com.cn/s/blog_77eab95f0101t8qp.html

查询table，type段是'table'，name段是table的名字,so:

select name from sqlite_master where type='table' order by name;

查询indices，type段是'index',name是index的名字，tbl_name是index所拥有的table的名字

通过以下语句可查询出某个表的所有字段信息

PRAGMA table_info([tablename])

如果在程序中你可以通过sqlite_master表得到所有表的信息。

sqlite> select type,name,tbl_name from sqlite_master order by type;

type|name|tbl_name

index|sqlite_autoindex_t1_1|t1

index|sqlite_autoindex_numtable_1|numtable

table|t1|t1

table|numtable|numtable

table|test|test

table|sqlite_stat1|sqlite_stat1

table|MailLabel|MailLabel

sqlite>

sqlite_master结构如下
