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

bool oci_bind_by_name ( resource $statement , string $ph_name , mixed &$variable [, int $maxlength [, int $type ]] )

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. 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.

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

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.

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.
