Hi,
Somebody please help me. I have a table like this:
----------------
column1|column2 |
---------------
1 | 2 |
----------------
Both columns are type int(11). And here's what I do:
sprintf(initial _query, "%s %s LIMIT 1", select * from", tablename);
if ((return = mysql_query(&db master, initial_query)) != 0) {
exit(1);
}
if ((master = mysql_store_res ult(&dbmaster)) == 0) {
exit(1);
}
if ((master_fields = mysql_fetch_fie lds(master)) == NULL) {
exit(1);
}
master_column = mysql_num_field s(master);
//master_column = mysql_field_cou nt(&dbmaster);
mysql_free_resu lt(master);
for (i=0; i<master_column ; i++) {
printf ("field %d type is %d", i, master_fields[i].type);
printf ("field %d name is %s", i, master_fields[i].name);
}
This is just a snippet. Every variable is declared correctly. Here,
as expected, I get 2 as the return value for mysql_num_field s or
mysql_field_cou nt. However, in the for loop, I get weird values for
field type and get NULL for second column name:
Field 0 type is 134557680 Field 0 name is column1
Field 1 type is 3239533 Field 1 name is (null)
WHAT IS GOING ON? I am at a loss. Could this be a bug in MySQL? I'd
appreciate it if someone can shed some light on this? Thanks!
