[PHP-BUG] Bug #51476 [NEW]: odbc_execute doesn't return proper result
From:
Operating system: Linux
PHP version: 5.2.13
Package: ODBC related
Bug Type: Bug
Bug description:odbc_execute doesn't return proper result
Description:
Result status for odbc_execute() is not correctly returned for CREATE TABLE
statements. Tested with MySQL and PostgreSQL ODBC drivers. Execution of
odbc_execute() for SELECT/UPDATE/INSERT statements doesn't have that
effect.
Testing CREATE TABLE with isql utility from unixODBC correctly returns an
error on second execution (assuming that table didn't exist before).
Test script:
---
$stmt = odbc_prepare($db, "CREATE TABLE x(id int)");
if ($stmt === false) {
$error = true;
$resultStr = "Query: $query\nPrepare Error: " .
odbc_errormsg($db);
echo $resultStr . "\n";
} else {
// Executing query (if prepare went fine)
$result = odbc_execute($stmt, $parameterArray);
echo $resultStr . "\n";
}
if (!$result) {
echo "ODBC Error: " . odbc_error($db) . "\n";
$resultStr = "Query: $query\nExecute error: " .
odbc_errormsg($db);
echo $resultStr . "\n";
$error = true;
}
Expected result:
Execution of the test script should create table "x" during the first
execution without reporting an error. The second execution should report an
error.
Actual result:
--
Every execution of the script reports an error:
Execute error: [unixODBC]Error while executing the query (non-fatal);
ERROR: relation "x" already exists
The table "x" is successfully created during the first test script
execution.

New Comment:
I've added another test that clarifies the error a bit futher. The test
(below)
insert TWO records for any execution - for PostgreSQL ODBC driver. For
MySQL
driver, it's failing every second run, with not failing runs taking 2-3
seconds.
Nether effect is observed with isql utility from unixODBC (with same
drivers).
Second test:
