//VERSION 为 VARCHAR类型，如果是数字类型，也需要加双引号
//arg[0]="33"

    printf("Error happened %s ",sqlo_geterror(dbh));
   
}

stat = sqlo_commit(dbh);

sqlo_finish(dbh);

return (EXIT_SUCCESS);

}

方式二

int stat;
stat=sqlo_exec(dbh,"UPDATE TEST SET Age = 39 where ID = 1 and Name='jack'");

if (0>stat){
    
    printf("Error happened %s ",sqlo_geterror(dbh));
   
}

stat = sqlo_commit(dbh);

方式三

int stat;
char stmt[1024];
sprintf(stmt,"UPDATE TEST SET Age = 40 where ID = %d and Name = %s",1,"'mike'");
stat=sqlo_exec(dbh,stmt);
if (0>stat){
    printf("Error happened %s ",sqlo_geterror(dbh));
   
}
