Guys
I am trying to get info from a mysql database that stores the date in a
string format and return UTC format as well as a associated value. I can
use the following select() statement OK to take care of that :
mysql> select UNIX_TIMESTAMP(<Timestamp string>),<data
fields> from <table>;
This gives all the values in the table and the UTC timeformat
So, next I built libdbi was able to run a simple db connection to test
it all worked. I then moved on to try the above and got my values OK but
I get '0''s for the UTC TIMESTAMP. Anyone any ideas why this doesn't
work?
Cheers
Here's my src which compiles and runs OK but gives the partial output
below.. Any ideas ( I have played with the printf statement already ;-)
?
#include <stdio.h>
#include </usr/local/include/dbi/dbi.h>
int main() {
dbi_conn conn;
dbi_result result;
unsigned int updateLatency;
unsigned int time;
const char *name;
dbi_initialize(NULL);
conn = dbi_conn_new("mysql");
dbi_conn_set_option(conn, "host", "localhost");
dbi_conn_set_option(conn, "username", "sqluser");
dbi_conn_set_option(conn, "password", "");
dbi_conn_set_option(conn, "dbname", "test");
dbi_conn_set_option(conn, "encoding", "UTF-8");
if (dbi_conn_connect(conn) < 0) {
printf("Could not connect. Please check the option settings\n");
}
else {
result = dbi_conn_queryf(conn, "select
UNIX_TIMESTAMP(HIST_Timestamp),HIST_Node,updateLatency from TABLE");
if (result) {
while (dbi_result_next_row(result)) {
name = dbi_result_get_string(result, "HIST_Node");
time = dbi_result_get_uint(result,
"UNIX_TIMESTAMP(HIST_Timestamp)");
updateLatency = dbi_result_get_uint(result, "updateLatency");
printf("%s %d %d\n",name,updateLatency,time);
}
dbi_result_free(result);
}
dbi_conn_close(conn);
}
dbi_shutdown();
return 0;
}
Sample Output:
chimds05 34 0
chimds05 12 0
chimds05 13 0
chimds05 20 0
chimds05 10 0
chimds05 13 0
