I have a c++ prog inserting values from modbus to the mysql table.
Everything was working find and suddenly mysql started acting in a weird way.

Now if i use command line to insert the value in to the table it works fine and i can see the value being inserted to the table

but if i use my c program to transfer the data to the mysql table it doesnt update at all i tried reboot mysql server, reboot whole system, new table new database
everything but somehow it doesnt update the table from the c program.

my code for c++ is as below

ret = Opendb(pc,user,pass,db);
        printf("opendb = %d\n",ret);
        sprintf(command,"Insert into meter (Power) values (%f);",i);
       // printf("command = %s\n",command);
        ret = Insertdb(command);
        printf("Insertdb = %d\n",ret);

bool Insertdb(char *insert)
    if(mysql_query(conn, insert))
        fprintf(stderr, "%s\n",mysql_error(conn));
        return 0;
    else return 1;

above code works fine and returns 1 every time its being called so it is calling out the mysql server the way it should. but somehow when i check the server from the command line i dont see any value been inserted into the table. so even the c prog runs good table in mysql doesnt receive any updates somehow. pls pls help
