# cubrid_bind

Bind variables to a prepared statement as parameters

### Description

bool cubrid_bind ( resource `$req_identifier` , int `$bind_index` , mixed `$bind_value` [, string `$bind_value_type` ] )

The cubrid_bind function is used to bind values to a corresponding named or question mark placeholder in the SQL statement that was passed to cubrid_prepare. If `bind_value_type` is not given, string will be the default.

> Note:

> If the type of data to be bound is BLOB/CLOB, CUBRID will try to map the data as a PHP stream. If the actually bind value type is not stream, CUBRID will convert it to string, and use it as the full path and file name of a file on the client filesystem.

> If the type of data to be bound explicitly is ENUM, the $bind_value argument should be the enum element which is in string format.

> In CUBRID shard envrioment, the $bind_value_type must be included in the cubrid_bind function.

The following table shows the types of substitute values.

CUBRID Bind Date Types
Support | Bind Type | Corresponding SQL Type
--- | --- | ---
Supported | STRING | CHAR, VARCHAR
| NCHAR | NCHAR, NVARCHAR
| BIT | BIT, VARBIT
| NUMERIC or NUMBER | SHORT, INT, NUMERIC
| FLOAT | FLOAT
| DOUBLE | DOUBLE
| TIME | TIME
| DATE | DATE
| TIMESTAMP | TIMESTAMP
| OBJECT | OBJECT
| ENUM | ENUM
| BLOB | BLOB
| CLOB | CLOB
| NULL | NULL
Not supported | SET | SET
| MULTISET | MULTISET
| SEQUENCE | SEQUENCE

### Parameters

`req_identifier`

  Request identifier as a result of cubrid_prepare.

`bind_index`

  Location of binding parameters. It starts with 1.

`bind_value`

  Actual value for binding.

`bind_value_type`

  A type of the value to bind. (It is omitted by default. Thus, the system internally uses string by default. However, you need to specify the exact type of the value as an argument when they are NCHAR, BIT, or BLOB/CLOB).

### Return Values

`TRUE`, when process is successful.

`FALSE`, when process is unsuccessful.

### Changelog

Version | Description
--- | ---
8.3.1 | Added BLOB/CLOB data types support.

### Examples

Example #1 cubrid_bind example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
$result = cubrid_execute($conn, "SELECT code FROM event WHERE sports='Basketball' and gender='M'");
$row = cubrid_fetch_array($result, CUBRID_ASSOC);
$event_code = $row["code"];
cubrid_close_request($result);
$game_req = cubrid_prepare($conn, "SELECT athlete_code FROM game WHERE host_year=1992 and event_code=? and nation_code='USA'");
cubrid_bind($game_req, 1, $event_code, "number");
cubrid_execute($game_req);
printf("--- Dream Team (1992 United States men's Olympic basketball team) ---\n");
while ($athlete_code = cubrid_fetch_array($game_req, CUBRID_NUM)) {
$athlete_req = cubrid_prepare($conn, "SELECT name FROM athlete WHERE code=? AND nation_code='USA' AND event='Basketball' AND gender='M'");
cubrid_bind($athlete_req, 1, $athlete_code[0], "number");
cubrid_execute($athlete_req);
$row = cubrid_fetch_assoc($athlete_req);
printf("%s\n", $row["name"]);
}
cubrid_close_request($game_req);
cubrid_close_request($athlete_req);
cubrid_disconnect($conn);
?>`

The above example will output:

    --- Dream Team (1992 United States men's Olympic basketball team) ---
    Stockton John
    Robinson David
    Pippen Scottie
    Mullin C.
    Malone Karl
    Laettner C.
    Jordan Michael
    Johnson Earvin
    Ewing Patrick
    Drexler Clyde
    Bird Larry
    Barkley Charles

Example #2 cubrid_bind BLOB/CLOB example

`<?php
$con = cubrid_connect("localhost", 33000, "demodb", "dba", "");
if ($con) {
cubrid_execute($con,"DROP TABLE if exists php_cubrid_lob_test");
cubrid_execute($con,"CREATE TABLE php_cubrid_lob_test (doc_content CLOB)");
$sql = "INSERT INTO php_cubrid_lob_test(doc_content) VALUES(?)";
$req = cubrid_prepare($con, $sql);
$fp = fopen("book.txt", "rb");
cubrid_bind($req, 1, $fp, "clob");
cubrid_execute($req);
}
?>`

Example #3 cubrid_bind BLOB/CLOB example

`<?php
$con = cubrid_connect("localhost", 33000, "demodb", "dba", "");
if ($con) {
cubrid_execute($con,"DROP TABLE if exists php_cubrid_lob_test");
cubrid_execute($con,"CREATE TABLE php_cubrid_lob_test (image BLOB)");
$sql = "INSERT INTO php_cubrid_lob_test(image) VALUES(?)";
$req = cubrid_prepare($con, $sql);
cubrid_bind($req, 1, "cubrid_logo.png", "blob");
cubrid_execute($req);
}
?>`
