linux C语言数据库sqliet3的添加，删除，查看

linux下数据库sqlite3的添加，删除，查看。

这个程序需要先在命令下创建表。

程序：

#include <sqlite3.h>

#include <stdio.h>

#include <stdlib.h>

static sqlite3 *db = NULL;

static char *errmsg = NULL;

char ** result = NULL;

int num = 0;

int display(void *para,int ncolumn, char ** columnvalue,char *columnname[])//回调函数，用于显示

{

int i;

num++;

printf("num = %d\n",num);

printf("total column is %d\n",ncolumn);

for(i = 0; i < ncolumn; i++)

{

printf("%s %s\n",columnname[i],columnvalue[i]);

}

printf("===============================\n");

return 0;

}

int main()

{

int re;

int row;

int column;

int i;

int j;

re = sqlite3_open("test.db",&db);

if(re != 0)

{

printf("open error\n");

exit(1);

}

//sqlite3_exec(db,"insert into test values('chengzi8','321');",0,0,&errmsg);//添加

//sqlite3_exec(db,"delete from test where phone = '321';",0,0,&errmsg);//删除

sqlite3_exec(db,"select * from test;",display,NULL,&errmsg);//显示2使用回调函数

printf("%d\n",num);

#if 0

sqlite3_get_table(db,"select * from test;",&result,&row,&column,&errmsg);//显示

for(i = 0; i <= row; i++)

{

for(j = 0; j < column; j++)

{

printf("%s|",result[i * column + j]);

}

printf("\n");

}

sqlite3_free_table(result);//注销结果集

#endif

re = sqlite3_close(db);//关闭

if(re != 0)

{

printf("open error\n");

exit(1);

}

}
