(PECL CUBRID >= 8.3.0)
cubrid_bind — Bind variables to a prepared statement as parameters
$req_identifier,$bind_index,$bind_value,$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. If the type of data to be bound explicitly is ENUM, the
bind_valueargument should be the enum element which is in string format. In CUBRID shard envrioment, thebind_value_typemust 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 |

示例 #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);
?>以上示例会输出：
