cubrid_bindBind variables to a prepared statement as parameters

說明

cubrid_bind(
    resource $req_identifier,
    int $bind_index,
    mixed $bind_value,
    string $bind_value_type = ?
): bool

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_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

參數

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).

返回值

成功時返回 true, 或者在失敗時返回 false

更新日誌

版本 說明
8.3.1 Added BLOB/CLOB data types support.

範例

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'");
$row cubrid_fetch_array($resultCUBRID_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($game_req1$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_reqCUBRID_NUM)) {
    
$athlete_req cubrid_prepare($conn"SELECT name FROM athlete WHERE code=? AND nation_code='USA' AND event='Basketball' AND gender='M'");
    
cubrid_bind($athlete_req1$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);
?>

以上例程會輸出:

--- 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

示例 #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($req1$fp"clob"); 
    
cubrid_execute($req);  
}
?>

示例 #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($req1"cubrid_logo.png""blob"); 
    
cubrid_execute($req);  
}
?>
