oci_bind_by_name (PHP 5) oci_bind_by_name --
Binds the PHP variable to the Oracle placeholder
Descriptionbool oci_bind_by_name ( resource stmt, string ph_name, mixed &variable [, int maxlength [, int type]])
oci_bind_by_name() binds the PHP variable
variable to the Oracle placeholder
ph_name. Whether it will be used for
input or output will be determined at run-time and the necessary
storage space will be allocated. The length
parameter sets the maximum length for the bind. If you set
length to -1
oci_bind_by_name() will use the current length of
variable to set the maximum length.
If you need to bind an abstract datatype (LOB/ROWID/BFILE) you
need to allocate it first using the
oci_new_descriptor() function. The
length is not used for abstract datatypes
and should be set to -1. The type parameter
tells Oracle which descriptor is used. Possible
values are:
OCI_B_FILE - for BFILEs;
OCI_B_CFILE - for CFILEs;
OCI_B_CLOB - for CLOBs;
OCI_B_BLOB - for BLOBs;
OCI_B_ROWID - for ROWIDs;
OCI_B_NTY - for named datatypes;
OCI_B_CURSOR - for cursors, that were created
before with oci_new_cursor().
例子 1. oci_bind_by_name()example
<?php
/* oci_bind_by_name example thies at thieso dot net (980221)
inserts 3 records into emp, and uses the ROWID for updating the
records just after the insert.
*/
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "
INSERT INTO
emp (empno, ename)
VALUES
(:empno,:ename)
RETURNING
ROWID
INTO
:rid
");
$data = array(
1111 => "Larry",
2222 => "Bill",
3333 => "Jim"
);
$rowid = oci_new_descriptor($conn, OCI_D_ROWID);
oci_bind_by_name($stmt, ":empno", $empno, 32);
oci_bind_by_name($stmt, ":ename", $ename, 32);
oci_bind_by_name($stmt, ":rid", $rowid, -1, OCI_B_ROWID);
$update = oci_parse($conn, "
UPDATE

$sal = 10000;
while (list($empno, $ename) = each($data)) {
oci_execute($stmt);
oci_execute($update);
}
$rowid->free();
oci_free_statement($update);
oci_free_statement($stmt);
$stmt = oci_parse($conn, "
SELECT
*
FROM
emp
WHERE
empno
IN
(1111,2222,3333)
");
oci_execute($stmt);
while ($row = oci_fetch_assoc($stmt)) {
var_dump($row);
}
oci_free_statement($stmt);
/* delete our "junk" from the emp table.... */
$stmt = oci_parse($conn, "
DELETE FROM
emp
WHERE
empno
IN
(1111,2222,3333)
");
oci_execute($stmt);
oci_free_statement($stmt);
oci_close($conn);

Remember, that this function strips trailing whitespace. See the following
example:
例子 2. oci_bind_by_name() example
<?php
$connection = oci_connect('apelsin','kanistra');
$query = "INSERT INTO test_table VALUES(:id, :text)";
$statement = oci_parse($query);
oci_bind_by_name($statement, ":id", 1);
oci_bind_by_name($statement, ":text", "trailing spaces follow ");
oci_execute($statement);
/*
This code will insert into DB string 'trailing spaces follow', without
trailing spaces
*/
?>

例子 3. oci_bind_by_name() example
<?php
$connection = oci_connect('apelsin','kanistra');
$query = "INSERT INTO test_table VALUES(:id, 'trailing spaces follow ')";
$statement = oci_parse($query);
oci_bind_by_name($statement, ":id", 1);
oci_execute($statement);
/*
And this code will add 'trailing spaces follow ', preserving
trailing whitespaces
*/
?>

| 警告 |
Do not use magic_quotes_gpc or
addslashes() and oci_bind_by_name()
simultaneously as no quoting is needed and any magically applied quotes
will be written into your database as oci_bind_by_name()
is not able to distinguish magically added quotings from those added
intentionally.
|
如果成功则返回 TRUE，失败则返回 FALSE。
注:
In PHP versions before 5.0.0 you must use ocibindbyname() instead.
This name still can be used, it was left as alias of
oci_bind_by_name() for downwards compatability.
This, however, is deprecated and not recommended.
