how to lock multiple rows in oracle?

["Rasim ŽEN" <rasimsen@xxxxxxxxxxx>]

Hi friends ,

my code like this

  $sql="SELECT mid,substr(ROWID,0,100) as nROWID,MEMBER_ID, NAME, SURNAME,
E_MAIL, SUBJECT, MAIL_BODY, to_char(DATE_CREATED,'DD.MM.YYYY HH24:MI:SS') as
DATE_CREATED, RETRY, PRIORITY, E_MAIL_FROM, RECEIVER_MEMBER_ID,
RECEIVER_NAME, RECEIVER_SURNAME, MAIL_TYPE, ATTACHMENT1, ATTACHMENT2,
EMBEDDING1, EMBEDDING2 FROM MEMBERS_TO_MAIL_SEND_HTML where flag=0 and
rownum<2000";

  putenv("NLS_LANG=TURKISH_TURKEY.WE8ISO8859P9");
  $baglanti = ocilogon(USERNAME,PASSWORD,DATABASE);

  $statement = ociparse ($baglanti, $sql);
  ociexecute ($statement);
  $i=0;


  while (ocifetchinto ($statement,$row, OCI_ASSOC)) {
    ........
    ........


I want to lock this 2000 rows, for this I make query like below:

  $sql=" .............. FROM MEMBERS_TO_MAIL_SEND_HTML where flag=0 and
rownum<2000 FOR UPDATE";

    this time, it is updateting only one row.

I tried to use "LOCK TABLE table IN ROW SHARE MODE;LOCK TABLE table IN ROW
SHARE MODE;"; but I don't know how to use in php.


How can I lock all rows, any advice ?

Thanks a lot
rasim
