Description:

Hello,

I've been facing difficulties with walk a big number of records from a result set.

I am using the function db2_fetch_both in a method of a database adapter class to retrieve just one record at a time. The total number of records are: 5647 and when I reach record number 1600 the function crashed generating the below message in "Actual result" field.

I am copying table's description next:

TMP_TABLE
-----------------------------------------------------------------
| ID		| TYPE		| SIZE		| NULL		|
-----------------------------------------------------------------
| ID		| INTEGER	| 4		| NO		|
| SERVICE	| VARCHAR	| 30		| NO		|
| ID_v		| VARCHAR	| 30		| NO		|
| INFORMATION	| CLOB		| 65536		| YES		|
| EXP_LEVEL	| INTEGER	| 4		| NO		|
| IP4B		| BIGINT	| 8		| NO		|
| MODIFIED	| INTEGER	| 4		| YES		|
| DETAIL	| VARCHAR	| 200		| YES		|
| FALSPOS	| INTEGER	| 4		| YES		|
-----------------------------------------------------------------

I would like to notice you this database class adapter's method comes from "CodeCharge Studio 3.1" (http://www.codecharge.com) a well-know PHP Rapid Development Programme.

I can't give you more details about our PHP Server configuration for security reasons. I hope you understand it.

Thank you,

Reproduce code:
---------------
  function next_record() {
    if (!$this->Query_ID)
      return 0;
    $this->Record = db2_fetch_both($this->Query_ID) ;
    $this->Row += 1;

    $stat = is_array($this->Record);
    if (!$stat && $this->Auto_Free) {
      $this->free_result();
    }
    return $stat;
  }

Expected result:
----------------
Return true or false and assign a record to Record instance property and incremented 1 Row instance property.

Actual result:
--------------
db2_fetch_array() [function.db2-fetch-array]: Fetch Failure
