Bug description:Random string data returned for timestamp odbc field
Description:
------------
Using the Sage Line 50 ODBC driver (v15 or v16), when selecting a table
containing timestamp column values odbc returns a string type variable
containing random data - consistent for all rows in the resultset and
occasionally between requests but changing at random. This applies whether
using PDO or odbc_ functions.
Including an ISO 8601 timestamp value as a WHERE condition performs as
expected, so this appears to be a problem with the retrieval of a
resultset.
Additionally, calling odbc_field_type() on the column crashes php (valid
results are returned for other columns, including date values but not
timestamps, in the dataset). It appears this may be a result of the data
type not appearing in the table returned by odbc_gettypeinfo?
PHP is running as an apache module. Extensions enabled:
-php_mssql.dll
-php_mysql.dll
-php_apc.dll
-php_apd.dll
-php_gd2.dll
-php_uploadprogress.dll
-php_pdo.dll
-php_pdo_mysql.dll
-php_pdo_odbc.dll
ODBC settings:
odbc.allow_persistent = On
odbc.check_persistent = On
odbc.max_persistent = -1
odbc.max_links = -1
odbc.defaultlrl = 4096
odbc.defaultbinmode = 1
I can access the tables with the correct timestamps showing through ODBC in
Access and through ADO in a Delphi application.
Test script:
---------------
$conn= new PDO("odbc:DSN=SageLine50v16;Uid=manager;Pwd=");
$result=$conn->query("SELECT DATE, RECORD_CREATE_DATE
FROM AUDIT_JOURNAL
WHERE RECORD_CREATE_DATE>='2010-03-22 12:19:00'");
echo "Query Result\n";
if ($result) {
var_dump($result->fetch());
}
$connection = odbc_connect('SageLine50v16','manager','');
$result=odbc_columns($connection, "%", "%", "AUDIT_JOURNAL",
"RECORD_CREATE_DATE");
echo "RECORD_CREATE_DATE ";
print_r(odbc_fetch_array($result));
echo "DATE ";
$result=odbc_columns($connection, "%", "%", "AUDIT_JOURNAL",
"DATE");
print_r(odbc_fetch_array($result));
$result= odbc_gettypeinfo($connection);
echo "TypeInfo\n";
odbc_result_all($result);
$result=odbc_exec($connection, "SELECT DATE, RECORD_CREATE_DATE
FROM AUDIT_JOURNAL;");
echo "Field Name\tType\n";
echo odbc_field_name($result, 1),"\t\t",odbc_field_type($result, 1);
/* The following causes php to terminate unexpectedly */
//echo odbc_field_name($result, 2),"\t\t\t",odbc_field_type($result, 2);
Expected result:
----------------
Expect to see:
- result array with a valid timestamp in RECORD_CREATE_DATE rather than
mangled string.
- A non-null TYPE_NAME key in the odbc_columns() return value for the
RECORD_CREATE_DATE field.
- Presumably, a value in the data type table returned by odbc_gettypeinfo
corresponding to data type #11 - there is no row for this though notably #9
maps to the DATE type and #10 to TIME, so #11 would fit as Timestamp?
- A return value for the odbc_field_type for the RECORD_CREATE_DATE column.
Actual result:
--------------
