oci_bind_by_name
(PHP 5, PECL oci8:1.1-1.2.4)
oci_bind_by_name — Binds the PHP variable to the Oracle placeholder
Description
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.
Parameters
- statement
-
An OCI statement.
- ph_name
-
The placeholder.
- variable
-
The PHP variable.
- maxlength
-
Sets the maximum length for the bind. If you set it to -1, this function will use the current length of variable to set the maximum length.
- type
-
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. Default to SQLT_CHR. Possible values are:
-
SQLT_FILE - for BFILEs;
-
SQLT_CFILE - for CFILEs;
-
SQLT_CLOB - for CLOBs;
-
SQLT_BLOB - for BLOBs;
-
SQLT_RDD - for ROWIDs;
-
SQLT_NTY - for named datatypes;
-
SQLT_INT - for integers;
-
SQLT_CHR - for VARCHARs;
-
SQLT_BIN - for RAW columns;
-
SQLT_LNG - for LONG columns;
-
SQLT_LBI - for LONG RAW columns;
-
SQLT_RSET - for cursors, that were created before with oci_new_cursor().
-
Return Values
Returns TRUE on success or FALSE on failure.
Examples
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);
$sal = 10000;
foreach ($data as $empno => $ename) {
oci_execute($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, this function strips trailing whitespaces. 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
*/
?>
Return Values
Returns TRUE on success or FALSE on failure.
Notes
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.
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.
