(1) 程式碼：
treehrt@treehrt-BM6AE-BM1AE-BP1AE:~/mysqlc$ cat t12.c
#include <my_global.h>
#include <mysql.h>
int main(int argc, char **argv)
{
printf("MySQL client version: %s\n", mysql_get_client_info());
MYSQL *con = mysql_init(NULL);
if (con == NULL)
{
fprintf(stderr, "%s\n", mysql_error(con));
exit(1);
}
if (mysql_real_connect(con, "localhost", "treehrt", "abc123abc123",
"ilvssell", 0, NULL, 0) == NULL)
{
fprintf(stderr, "%s\n", mysql_error(con));
mysql_close(con);
exit(1);
}
if (mysql_query(con, "DROP TABLE IF EXISTS new_outcome"))
{
fprintf(stderr, "%s\n", mysql_error(con));
mysql_close(con);
exit(1);
}
printf("DROP TABLE new_outcome ok!\n");
mysql_query(con, "set names utf8");
char st[]="CREATE TABLE new_outcome(flush int default 0,sheet char(20) primary key default '20181029A00001',custno char(10) default '-', amount int default 0,opday char(20) default '2018-10-29 20:25:00')";
if (mysql_query(con, st)) {
fprintf(stderr, "%s\n", mysql_error(con)); mysql_close(con); exit(1);
}
printf("Execute[%s] ok!!\n", st);
sprintf(st,"%s","insert into new_outcome (flush,sheet,custno,amount,opday) values (0,'20181029A00001','712003',550,'2018-10-29 20:25:00')");
if (mysql_query(con, st)) {
fprintf(stderr, "%s\n", mysql_error(con)); mysql_close(con); exit(1);
}
printf("Execute[%s] ok!!\n", st);
mysql_close(con);
exit(0);
}
(2)編譯：
treehrt@treehrt-BM6AE-BM1AE-BP1AE:~/mysqlc$ gcc t12.c `mysql_config --cflags --libs`
（3）執行
treehrt@treehrt-BM6AE-BM1AE-BP1AE:~/mysqlc$ ./a.out
MySQL client version: 5.7.22
DROP TABLE new_outcome ok!
Execute[CREATE TABLE new_outcome(flush int default 0,sheet char(20) primary key default '20181029A00001',custno char(10) default '-', amount int default 0,opday char(20) default '2018-10-29 20:25:00')] ok!!
Execute[insert into new_outcome (flush,sheet,custno,amount,opday) values (0,'20181029A00001','712003',550,'2018-10-29 20:25:00')] ok!!
（4）在mysql命令列查看
