cubrid_bind
(PECL CUBRID >= 8.3.0)
Bind variables to a prepared statement as parameters
Description
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.
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 environment, the bind_value_type must be included in the cubrid_bind() function.
The following table shows the types of substitute values.
| 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_identifierRequest identifier as a result of
cubrid_prepare().bind_indexLocation of binding parameters. It starts with 1.
bind_valueActual value for binding.
bind_value_typeA 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
Success

Examples
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");
