    示例 #1 cubrid_lob2_write() example 1

    <?php
    // test_lob (id INT, contents CLOB)

    $conn = cubrid_connect("localhost", 33000, "demodb", "dba", "");

    cubrid_execute($conn,"DROP TABLE if exists test_lob");
    cubrid_execute($conn,"CREATE TABLE test_lob (id INT, contents CLOB)");

    $req = cubrid_prepare($conn, "INSERT INTO test_lob VALUES(2, ?)");

    $lob = cubrid_lob2_new($conn, 'CLOB');
    $len = cubrid_lob2_write($lob, "Hello world");

    cubrid_lob2_bind($req, 1, $lob);

    $req = cubrid_prepare($conn, "INSERT INTO test_lob VALUES(1, ?)");
    $lob1 = cubrid_lob2_new($conn, 'CLOB');
    $len = cubrid_lob2_write($lob1, "cubrid php driver");
    cubrid_lob2_bind($req, 1, $lob1);
    cubrid_execute($req);

    $req = cubrid_execute($conn, "select * from test_lob");

    $row = cubrid_fetch_row($req, CUBRID_LOB);
    $lob2 = $row[1];
    cubrid_lob2_seek($lob2, 0, CUBRID_CURSOR_LAST);
