>Description:
On an unsuccessful INSERT DELAYED using mysql_query(), there is disagreement
between the two functions mysql_error() and mysql_errno(). Specifically,
mysql_errno() will return 0 (indicating no error), whereas mysql_error()
will return what really happened, e.g. "Table 'foo' doesn't exist".
>How-To-Repeat:
int retval;
unsigned int real_error;
char *query="insert delayed into `headers_out` (id, item, val) values
('PfF5PsCoCj0AAEVCCiY','Content-Type','text/html')";
/* table "headers_out" hasn't been created yet... */
retval = mysql_query(mysql_log, query);
real_error = mysql_errno(mysql_log);
printf("Error %d, means %s", real_error, mysql_error(mysql_log));
What gets output from this pseudocodish snippet is:
"Error 0, means Table 'apache_test.notes' doesn't exist"
>Fix:
Obviously the two error functions should agree; either, both reporting 'no
error' or both agreeing that error 1146, nonexistent table, just happened.
It would be preferable for the latter to be the fix, so one could then
still check for success or failure of the INSERT DELAYED. I do confess that
a strict reading of the INSERT DELAYED docs indicates that it doesn't bother
to wait around to check for success/failure...so the "desired" fix might not
be totally in line with the "strict, by-the-book" fix. It sure would be
nice to know the fate of the delayed insert, though...
