# oci_bind_by_name

(PHP 5)

oci_bind_by_name -- Binds the PHP variable to the Oracle placeholder

## Description

bool 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().

예 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
emp
SET
sal = :sal
WHERE
ROWID = :rid
");
oci_bind_by_name($update, ":rid", $rowid, -1, OCI_B_ROWID);
oci_bind_by_name($update, ":sal", $sal, 32);
$sal = 10000;
while (list($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:

예 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 */ ?>`

예 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 */ ?>`

주의
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.

성공일 경우 `TRUE`를, 실패일 경우 `FALSE`를 반환합니다.

> 참고: 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.
