(PECL CUBRID >= 8.3.0)
cubrid_bind — 将变量绑定到预处理语句作为参数
cubrid_bind() 函数用于将值绑定到传递给 cubrid_prepare() 的 SQL 语句中相应的命名或问号占位符。如果未指定 bind_value_type，则默认类型为字符串。
注意:
如果要绑定的数据类型为 BLOB/CLOB，CUBRID 将尝试将数据映射为 PHP 流。如果实际绑定值类型不是流，CUBRID 会将其转换为字符串，并将其用作客户端文件系统上的文件完整路径和文件名。
如果要绑定的数据类型显式指定为 ENUM，则
bind_value参数应为字符串格式的枚举元素。在 CUBRID 分片环境中，必须在 cubrid_bind() 函数中包含
bind_value_type。
下表显示了替代值的类型。
| 支持 | 绑定类型 | 对应 SQL 类型 |
|---|---|---|
| 支持 | STRING | CHAR，VARCHAR |
| NCHAR | NCHAR，NVARCHAR | |
| BIT | BIT，VARBIT | |
| NUMERIC 或 NUMBER | SHORT，INT，NUMERIC | |
| FLOAT | FLOAT | |
| DOUBLE | DOUBLE | |
| TIME | TIME | |
| DATE | DATE | |
| TIMESTAMP | TIMESTAMP | |
| OBJECT | OBJECT | |
| ENUM | ENUM | |
| BLOB | BLOB | |
| CLOB | CLOB | |
| NULL | NULL | |
| 不支持 | SET | SET |
| MULTISET | MULTISET | |
| SEQUENCE | SEQUENCE |
req_identifier作为 cubrid_prepare() 结果的请求标识符。
bind_index绑定参数的位置。从 1 开始。
bind_value用于绑定的实际值。
bind_value_type要绑定的值的类型。（默认情况下省略。因此，系统默认情况下会使用字符串。但是，当它们是 NCHAR、BIT 或 BLOB/CLOB 时，您需要将值的精确类型指定为参数）。
| 版本 | 描述 |
|---|---|
| 8.3.1 | 添加了 BLOB/CLOB 数据类型支持。 |
示例 #1 cubrid_bind() 示例
<?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("--- 梦幻队 (1992 年美国男子奥运篮球队) ---\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);
