(PECL CUBRID >= 8.3.0)
cubrid_bind — Bind variables to a prepared statement as parameters
$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.
注意:
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.
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 | |
| BLOB | BLOB | |
| CLOB | CLOB | |
| NULL | NULL | |
| Not supported | SET | SET |
| MULTISET | MULTISET | |
| SEQUENCE | SEQUENCE |
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, system internally use 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).
TRUE, when process is successful.
FALSE, when process is unsuccessful.

| 8.3.1 | Added BLOB/CLOB data types support. |
例1 cubrid_bind() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$result = cubrid_execute($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);
?>
上の例の出力は以下となります。
