oci_bind_by_name
(no version information, might be only in CVS)
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().
Example 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:
Example 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
*/
?>
Example 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
*/
?>
Warning
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.
Returns TRUE on success or FALSE on failure.
Note: 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.
