Ubuntu下wxWidgets学生信息管理sqlite3（C++）
main.cxx
#include
<sqlite3.h> #include <cstdlib> #include <iostream> #include
<iomanip> using namespace std; int main() { sqlite3* file; int flag; flag
= sqlite3_open("./stu.db", &file);
if(SQLITE_OK != flag) {
cout<<"Database connect failed!"<<endl; exit(-1); }
cout<<"Database connect successes!"<<endl;
char** r; int row,
col; char* errmsg; string sql = "select * from stu"; flag =
sqlite3_get_table(file, sql.c_str(), &r, &row, &col, &errmsg);
if(SQLITE_OK == flag) { cout<<"Statement executes
sucesses!"<<endl; int i, j;
for(i = 0; i <= row; i++) {
for(j = 0; j < col; j++) { cout<<r[i*col+j]<<‘ ‘; }
cout<<endl; }
} sqlite3_close(file); return 0; }
makefile
all:
main.o g++ main.o -o t.exe -lsqlite3 main.o: main.cxx g++ -c main.cxx -o
main.o
.PHONY:clean
clean: rm main.o t.exe
1.先在线安装sqlite3，试用一下命令安装
ubuntu@ubuntu-virtual-machine:~$
sudo apt-get install sqlite3
2.安装成功后测试会出现
ubuntu@ubuntu-virtual-machine:~$
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
ubuntu@ubuntu-virtual-machine:~$
which sqlite3
/usr/bin/sqlite3
ubuntu@ubuntu-virtual-machine:~$
ls
core
OSlab1 Public
Videos
Desktop
OSlab2 Qt

4.具体sqlite3操作的实例
ubuntu@ubuntu-virtual-machine:~$
mkdir mydb
ubuntu@ubuntu-virtual-machine:~$
cd mydb
ubuntu@ubuntu-virtual-machine:~/mydb$
ls
ubuntu@ubuntu-virtual-machine:~/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
ubuntu@ubuntu-virtual-machine:~/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
ubuntu@ubuntu-virtual-machine:~$
cd StuMana
ubuntu@ubuntu-virtual-machine:~/StuMana$
sqlite3 stuinfo.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 stuinfo (id char(10),name char(15) not null,dormitoryid char(20)
not null,phone char(11),qq char(13));
sqlite>
insert into stuinfo
values(‘1115115247‘,‘LiYa‘,‘15#501‘,‘15530061772‘,‘614100932‘);
sqlite>
insert into stuinfo
values(‘1115115276‘,‘ZhangAihua‘,‘15#424‘,‘18330000036‘,‘627100056‘);
sqlite>
select * from stuinfo;
1115115247|LiYa|15#501|15500761772|614100932
1115115276|ZhangAihua|15#424|18330000036|627100056
sqlite>
.exit
ubuntu@ubuntu-virtual-machine:~/StuMana$
ls
bin
stuinfo.db StuMana.depend
WxWizFrame.fbp
GUIFrame.cpp
StuManaApp.cpp StuMana.layout WxWizFrame.fbp.bak
GUIFrame.h
StuManaApp.h StuManaMain.cpp
obj
StuMana.cbp
StuManaMain.h
ubuntu@ubuntu-virtual-machine:~/StuMana$
6.在CodeBlocks的link
那里添加 libsqlite3.so和libsqlite3.so.0的路径（usr/local/lib）
