1.先在线安装sqlite3，试用一下命令安装
[email protected]:~$
sudo apt-get install sqlite3
2.安装成功后测试会出现
[email protected]:~$
sqlite3
SQLite
version 3.7.9 2011-11-01 00:52:41
Enter
".help" for instructions
Enter
SQL statements terminated with a ";"
sqlite>
.exit
3.查找sqlite3的路径
[email protected]:~$
which sqlite3
/usr/bin/sqlite3
[email protected]:~$
ls
core

4.具体sqlite3操作的实例
[email protected]:~$
mkdir mydb
[email protected]:~$
cd mydb
[email protected]:~/mydb$
ls
[email protected]:~/mydb$
sqlite3 stu.db
SQLite
version 3.7.9 2011-11-01 00:52:41
Enter
".help" for instructions
Enter
SQL statements terminated with a ";"
sqlite>
create table stu(sno int primary key, sname text not null, sage int);
sqlite>
insert into stu(1, ‘Lisi‘, 20);
Error:
near "1": syntax error
sqlite>
insert into stu values(1, ‘lisi‘, 20);
sqlite>
insert into stu values(2, ‘zhangsan‘, 18);
sqlite>
select * from stu;
1|lisi|20
2|zhangsan|18
sqlite>
.exit
[email protected]:~/mydb$
ls
stu.db
6.记着在CodeBlocks的link
那里添加 libsqlite3.so和libsqlite3.so.0的路径（usr/local/lib）
5.具体sqlite3操作的实例
[email protected]:~$
cd StuMana
[email protected]:~/StuMana$
sqlite3 stuinfo.db

6.在CodeBlocks的link
那里添加 libsqlite3.so和libsqlite3.so.0的路径（usr/local/lib）
