Summary: odbc_execute doesn't return proper result
Status: Open
Type: Bug
Package: ODBC related
Operating System: Linux
PHP Version: 5.2.13
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:
------------
<?php
$db = @odbc_connect("DSN=PostgreSQL;Server=localhost;Database=demo",
$user,
$password);
if (!$db) {
echo odbc_errormsg() . "\n";
return;
}
$query = "INSERT INTO t1 VALUES(2,'test',100)";
$stmt = odbc_prepare($db, $query);
if ($stmt === false) {
$error = true;
echo "Query: $query\nPrepare Error: " . odbc_errormsg($db) .
"\n";
return;
} else {
$result = odbc_execute($stmt, array());
}
if (!$result) {
echo "Query: $query\nExecute error: " . odbc_errormsg($db);
return;
}
echo "Ok\n";
odbc_free_result($stmt);
?>

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.
