the question is on the callback function's return values of sqlite3_exec()
when using sqlite3_exec() to do "select * from ...", how to get all the
return values by using the callback function?
struct olt_info
{
int olt_index;
int olt_logo;
char* olt_line;
// int nmber;
};
int my_callback(void *olt_temp, int argc, char *value[], char *name[])
{
struct olt_info *pdata = NULL;
pdata = (struct olt_info *)olt_temp;
int jj;
for (int i = 0; i < argc; i++)
jj = printf("%s == %s\n", name[i], value[i]);
pdata->olt_index = (int)atoi(value[0]);
pdata->olt_logo = (int)atoi(value[1]);
pdata->olt_line = value[2];
return 0;
}
it could print the result, but couldn't return the values. If do like so,
just one value could be get.
how to get all the values?
