# 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:

- `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().

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 */ ?>`

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.
