I've gone through a lot in the course of diagnosing this problem so I can't recall exactly what changed, but originally I was getting this error: ORA-01460: unimplemented or unreasonable conversion requested The resolution has been to define the length for that parameter: $stmt->bindParam( ':notes', $this->notes, PDO::PARAM_STR, 4000 ); Why this fixes the problem is still a mystery. None of the inserted data is lost, so there don't appear to have really been too many bytes in the string to insert. I'm not experiencing the same problem with any of the smaller columns (a string of 4 or more characters will insert into a column defined varchar2(10), for example). ------------------------------------------------------------------------ [2008-04-01 03:28:49] charles at crh-systems dot com I am having the same problem, OCIStmtExecute: ORA-01461: can bind a LONG value only for insert into a LONG column I can only get 1333 chars to insert into a clob field no matter which connection charset I use. 4000 / 3 = 1333.333 ...any fixes? ------------------------------------------------------------------------ [2007-03-12 18:27:14] jarismar at adplabs dot com dot br Many thanks for the faster reply, I've tested with suggested snapshot PHP Version: 5.2.2-dev Build Date : Mar 12 2007 16:05:36 But the problem still occurs. It seems that PDO get wrong data type for the CLOB column. I can just insert up to 4000 bytes into the CLOB column, because the extension thinks its handling a LONG column. ------------------------------------------------------------------------ [2007-03-12 17:36:53] jarismar at adplabs dot com dot br Description: ------------ I'm using pdo_oci and oracle 10g (10.2). Trying to insert into a CLOB column using multi-byte charset (AL32UTF8) results on the following error: ORA-01461: can bind a LONG value only for insert into a LONG column. The column datatype in not LONG it's a CLOB ! Changing the connection charset to use WE8ISO8859P1 or any other single byte charset solve the problem (the insert command ends with no error), but I loose all non ISO characters (my data gets corrupted). Reproduce code: --------------- try { $sDSN = "oci:dbname=$sConId;charset=AL32UTF8"; $oPDO = new PDO($sDSN, $sUserName, $sPassword); $oPDO->beginTransaction(); $oStmt = $oPDO->prepare("insert into test_clob (id, data) values (:id, EMPTY_CLOB())"); $iID = 1; $oStmt->bindParam(':id', $iID); if ($oStmt->execute()) { $oStmt = $oPDO->prepare("update test_clob set data=:value where id=1"); $sData = str_repeat('x', 65535); $oStmt->bindParam(':value', $sData); if ($oStmt->execute() === false) { throw new Exception('Error on update clob'); } } else { throw new Exception('Error on insert EMPTY_CLOB'); } $oStmt = $oPDO->prepare("select data from test_clob where id = :id"); $oStmt->bindParam('id', $iID); $oStmt->execute(); $oResult = $oStmt->fetch(); echo 'Read '.strlen(stream_get_contents($oResult['DATA'])).' characters <br>'; $oPDO->commit(); } catch (Exception $oE) { if ($oStmt) { echo '<pre>';print_r($oStmt->errorInfo());echo "</pre><br>\n"; } echo $oE->getMessage()."<br>\n"; } $oPDO = null; Expected result: ---------------- Read 65535 characters Actual result: -------------- Array ( [0] => HY000 [1] => 1461 [2] => OCIStmtExecute: ORA-01461: can bind a LONG value only for insert into a LONG column (ext\pdo_oci\oci_statement.c:142) ) Error on update clob ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40787&edit=1
