ok i'll leave it that way, but just a suggestion for the new version isn't it strange to make method WriteTemporary to accept second param, which explicitly tells the object, which type of instance it is? can't it be done when binding it (OCIBindByName) to something to change the type of object so it knows what it is bound to (blob,clob or whatever), or when created to tell it the type OCINewDescriptor with the last param Previous Comments: ------------------------------------------------------------------------ [2004-02-04 03:55:49] [EMAIL PROTECTED] In php 4.3.x method writeTemporary() doesn't accept second parameter, which exists only in php5 branch. This parameter should be used to tell method wich type of Lob you're trying to write. Thus, in php4.3.x writeTemporary always tries to create CLOB, and you're using it to write BLOB. The example in docs should be changed, I'm working on new docs atm. ------------------------------------------------------------------------ [2004-01-29 11:46:35] [EMAIL PROTECTED] ok, I'll take a look at it soon. ------------------------------------------------------------------------ [2004-01-29 11:16:59] ceco at noxis dot net in examle 2 on http://www.php.net/manual/en/function.ocinewdescriptor.php it is used exactly like that, only it is clob I cannot use php 5, I made workaround converting blob to hex, sending it as clob and then reconverting it to binary ;-)) a little strange and cpu intensive but works and since it is not very often used I'll have to leave it that way ------------------------------------------------------------------------ [2004-01-29 09:21:23] [EMAIL PROTECTED] Don't use writeTemporary, it's not intended for writing persistent LOB's. You should use save() or you can upgrade to PHP5 and use $lob->write() method. ------------------------------------------------------------------------ [2004-01-29 06:29:33] ceco at noxis dot net Description: ------------ first of all I should say that it may be documentation problem, because didn't find good documentation of the LOB object i have a oracle procedure, which accepts BLOB (see the code below) it inputs the data in the blob but when i extract (with the oracle tools or with other php script) it is corrupted it is exactly 2 times larger when everything is changed to clob (of course the data is text not jpg), this function work ok also it is workig for me if I use insert into (the_blob) values (empty_blob()) returning the_blob into :the_blob and then bind $lob and use $lob->save but i don't want to have this I think $lob->WriteTemporary mangles the data somehow and corrupts it Reproduce code: --------------- include_once 'config/environment.inc.php'; $fd = fopen('Sample.jpg', 'r'); $data = fread($fd, filesize('Sample.jpg')); fclose($fd); $conn = ocilogon($CFG_DB['username'], $CFG_DB['password'], $CFG_DB['db']); $lob = OCINewDescriptor($conn, OCI_D_LOB); $stmt = OCIParse($conn,"begin TEST_PROC(:the_blob); end;"); OCIBindByName($stmt, ':the_blob', &$lob, -1, OCI_B_BLOB); $lob->WriteTemporary($data); OCIExecute($stmt, OCI_DEFAULT); $lob->close(); $lob->free(); OCICommit($conn); create procedure TEST_PROC(the_blob blob) is begin insert into test_table values (the_blob); end; create table test_table (the_blob blob); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27083&edit=1
