Summary: Load stmt result bool false
Status: No Feedback
Type: Bug
Package: MySQLi related
Operating System: Linux mandriva 2009
PHP Version: 5.3CVS-2009-02-14 (snap)
Assigned To: mysql

New Comment:
The bug happens if you do a SELECT before the LOAD DATA. In the script
above
(comment [2009-08-25 13:24 UTC] [email protected]), if you insert these lines
before
the LOAD DATA query:
$res = $mysqli->query("SELECT * FROM foo limit 1");
printf("SELECT -> %s\n", var_export($res, true));
... then the LOAD DATA query will return false. Note that even though
the LOAD
DATA returns false, the data is inserted successfully.
I created a new bug for this the other day:
http://bugs.php.net/bug.php?id=53503
Sorry for the duplicate

Running the example gives:
bool(true)
array(1) {
[0]=>
string(4) "test"
}
bool(true)
Warning: mysqli::query(): (42S22/1054): Unknown column 'APP
LICANT_NO' in 'field list' in
/home/nixnutz/src/login/PHP_5_3/bug47387.php on line 85
bool(false)
Please verify if that is the cause of the bool(false).
A short LOAD DATA test such as the one below does not show any
differences between PHP 5.2 and PHP 5.3 on my box. Would be great, if
you could try that one as well.
$mysqli = new mysqli("127.0.0.1", "root", "root");
$res = $mysqli->query("USE phptest");
printf("USE phptest -> %s\n", var_export($res, true));
$mysqli->query("DROP TABLE IF EXISTS foo");
$res = $mysqli->query("CREATE TABLE IF NOT EXISTS foo (id INT, bar
CHAR(2))");
printf("CREATE TABLE -> %s\n", var_export($res, true));
$file = tempnam(sys_get_temp_dir(), "bug47387");
var_dump($file);
$fp = fopen($file, "w");
fwrite($fp, "1;a\n");
fclose($fp);
$res = $mysqli->query(sprintf("LOAD DATA LOCAL INFILE '%s' INTO TABLE
foo FIELDS TERMINATED BY ';'", $file));
printf("LOAD DATA -> %s\n", var_export($res, true));
$res = $mysqli->query("SELECT * FROM foo");
if ($res)
while ($row = $res->fetch_assoc())
var_dump($row);

I couldn't reproduce using myslqnd and libmysql currently creates other
trouble for me. but I'll investigate. Thanks for the short script so far
:-)

Hi,
I can reproduce 'the bug' with attached ugly code. you can use the
infile I supplied earlier. the problem seems a bit tricky.
1 $result = $mysqli->query('CREATE TABLE IF NOT EXISTS ...'
2 $result = $mysqli->query("SHOW WARNINGS", MYSQLI_USE_RESULT...
this shows one warning:
Note (1050): Table 'PROJECT_DETAIL' already exists
3 $result->close();
4 Now when I run $result = $mysqli->query(LOAD DATA LOCAL INFILE ...
then $result is false and I get the warning:
//PHP Warning: mysqli::query(): (00000/0): ...
Note! this only happen in 5.3, in 5.2 $result is true.
Look in the code for the snippet that prevent the 'bug'.
Please let me know if there anything more I can do.

Hi, how do I use/set 'feedback'?
I have made my script a bit simpler. I can reproduce this without
forking. What seems to trigger this odd behavior is the first CREATE
TABLE. If I run a TRUNCATE table PROJECT_DETAIL, or a DELETE from
PROJECT_DETAIL where 1=2 in between the subsequent LOAD results as it
should. So I can circumvent the problem by inserting a dummy delete.
(I tried to insert a SELECT * from PROJECT_DETAIL where 1=2 in between,
but that didn't work)
I do one more attempt this weekend to expose the problem.
