PHP 5.1.2
SDO 1.0.1
DB2 8.2FP12

When creating a a new row in a simple table $das->applyChanges () returns with SQLSTATE 22005 indicating that it thinks that there is a type missmatch between the expected column types and the provided column types. 

It should be noted that this example works with PHP 5.1.4 so maybe this is just a case of pointing out that this problem can arrise with PHP 5.1.2

Reproduce code:
---------------
Simple table

-- CREATE TABLE "INTEROP"."ALLTYPE"  (
CREATE TABLE "SIMON"."ALLTYPE"  (
		  "ASMALLINT" SMALLINT NOT NULL , 
		  "AINT" INT,
		  "AVARCHAR" VARCHAR(14))   
		 IN "USERSPACE1" ; 
ALTER TABLE "SIMON"."ALLTYPE" 
	ADD PRIMARY KEY
		("ASMALLINT");

Simple test to read data and insert a row

    // Describe the structure of the alltype table
    $alltype_table = array('name' => 'alltype',
                           'columns' => array('asmallint', 'aint', 'avarchar'),
                           'PK' => 'asmallint');
...

      // construct the SQL query for alltype retrieval
      $stmt = "select asmallint, aint, avarchar from alltype";
    
      // execute the query to retrieve the departments
      $root = $das->executeQuery($dbh, $stmt);

...
      //create a new row in the table
      $newrow = $root -> createDataObject('alltype');
      
      // set the properties
      $newrow->asmallint = $count;
      $newrow->aint = 4;
      $newrow->avarchar = 'PHP XP';

      $das->applyChanges($dbh, $root);

Gives rise to follwoing error. The test code works fine on MySQL so it would seem that there is something suspect about the SDO/PDO ODBC/DB2 path

SDO/DAS/Relational.php::applyChanges encountered an error when attempting to exe
cute INSERT INTO alltype (asmallint,aint,avarchar) VALUES (?,?,?);
PDO reported no rows affected by the SQL statement.
This may happen if the data that was retrieved and updated has been changed by a
nother processs in the database in the meantime.
The error information returned from PDO::errorInfo() was:
  SQLSTATE: 22005
  Driver-specific error code: -99999
  Driver-specific error message: [IBM][CLI Driver] CLI0112E  Error in assignment
. SQLSTATE=22005 (SQLExecute[-99999] at ext\pdo_odbc\odbc_stmt.c:133)
All changes have been rolled back.<br/><br/>

Expected result:
----------------
I expected a new row to be added to the database

Actual result:
--------------
Failed with SQLSTATE 22005 indicating that DB2 thinks that there is a type missmatch between the expected column types and the provided column types.
