maxdb_stmt_bind_param

(PECL)

(no version information, might be only in CVS)

stmt->bind_param -- Binds variables to a prepared statement as parameters

Description

Procedural style:

bool maxdb_stmt_bind_param ( resource stmt, string types, mixed &var1 [, mixed &...] )

Object oriented style (method):

class stmt {

bool bind_param ( string types, mixed &var1 [, mixed &...] )

}

Procedural style (extended syntax):

bool maxdb_stmt_bind_param ( resource stmt, string types, array &var )

Object oriented style (method) (extended syntax):

class stmt {

bool bind_param ( string types, array &var )

}

maxdb_stmt_bind_param() is used to bind variables for the parameter markers in the SQL statement that was passed to maxdb_prepare(). The string types contains one or more characters which specify the types for the corresponding bind variables.

The extended syntax of maxdb_stmt_bind_param() allows to give the parameters as an array instead of a variable list of PHP variables to the function. If the array variable has not been used before calling maxdb_stmt_bind_param(), it has to be initialized as an emtpy array. See the examples how to use maxdb_stmt_bind_param() with extended syntax.

Variables for SELECT INTO SQL statements can also be bound using maxdb_stmt_bind_param(). Parameters for database procedures can be bound using maxdb_stmt_bind_param(). See the examples how to use maxdb_stmt_bind_param() in this cases.

If a variable bound as INTO variable to a SQL statement was used before, the content of this variable is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param().

For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output value of the database procedure. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param().

Таблица 1. Type specification chars

Character	Description
i	corresponding variable has type integer
d	corresponding variable has type double
s	corresponding variable has type string
b	corresponding variable is a blob and will be send in packages

Return values

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Example

Пример 1. Object oriented style


<?php
$maxdb = new maxdb('localhost', 'MONA', 'RED', 'DEMODB');

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$maxdb->query ("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query ("INSERT INTO temp.mycity SELECT * FROM hotel.city");

$stmt = $maxdb->prepare("INSERT INTO temp.mycity VALUES (?, ?, ?)");
$stmt->bind_param('sss', $zip, $name, $state);

$zip = '11111';
$name = 'Georgetown';
$state = 'NY';

/* execute prepared statement */
$stmt->execute();

printf("%d Row inserted.\n", $stmt->affected_rows);

/* close statement and connection */
$stmt->close();

/* Clean up table CountryLanguage */
$maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'");
printf("%d Row deleted.\n", $maxdb->affected_rows);

/* close connection */
$maxdb->close();
?>

Пример 2. Procedural style


<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (!$link) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

maxdb_query ($link, "CREATE TABLE temp.mycity LIKE hotel.city");
maxdb_query ($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");

$stmt = maxdb_prepare($link, "INSERT INTO temp.mycity VALUES (?, ?, ?)");
maxdb_stmt_bind_param($stmt, 'sss', $zip, $name, $state);

$zip = '11111';
$name = 'Georgetown';
$state = 'NY';

/* execute prepared statement */
maxdb_stmt_execute($stmt);

printf("%d Row inserted.\n", maxdb_stmt_affected_rows($stmt));

/* close statement and connection */
maxdb_stmt_close($stmt);

/* Clean up table CountryLanguage */
maxdb_query($link, "DELETE FROM temp.mycity WHERE name='Georgetown'");
printf("%d Row deleted.\n", maxdb_affected_rows($link));

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

1 Row inserted.
1 Row deleted.

Пример 3. Procedural style (SELECT INTO)


<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (!$link) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}
   
/* Performing SQL query */
$stmt = maxdb_prepare ($link, "SELECT price INTO ? FROM hotel.room where hno = ? and type = ?");
if (!$stmt) {
  printf ("Prepare failed: %s\n", maxdb_error($link));
}

$hno = "50";
$rtype = "suite";

maxdb_stmt_bind_param($stmt, 'dss', $price, $hno, $rtype);
maxdb_stmt_execute($stmt);

printf ("%f\n", $price);

maxdb_stmt_close ($stmt);
?>

The above examples would produce the following output:

21.600000

Пример 4. Procedural style (DB procedure)


<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (!$link) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

maxdb_report (MAXDB_REPORT_OFF);
maxdb_query($link,"DROP DBPROC test_proc");
maxdb_report (MAXDB_REPORT_ERROR);

$query = "create dbproc test_proc (INOUT e_text char(72)) AS select * from SYSDBA.DUAL; fetch into :e_text;";

maxdb_query($link, $query);

/* Performing SQL query */
$stmt = maxdb_prepare ($link, "CALL test_proc (?)");
if (!$stmt) {
  printf ("Prepare failed: %s\n", maxdb_error($link));
}

maxdb_stmt_bind_param($stmt, 's', $result);
maxdb_stmt_execute($stmt);

printf ("%s\n", $result);

maxdb_stmt_close ($stmt);
?>

The above examples would produce the following output:

Пример 5. Object oriented style (extended syntax)


<?php
$maxdb = new maxdb('localhost', 'MONA', 'RED', 'DEMODB');

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$maxdb->query ("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query ("INSERT INTO temp.mycity SELECT * FROM hotel.city");

$stmt = $maxdb->prepare("INSERT INTO temp.mycity VALUES (?, ?, ?)");

$arr = array();

$stmt->bind_param('iss', $arr);

$arr[0] = 11111;
$arr[1] = 'Georgetown';
$arr[2] = 'NY';

/* execute prepared statement */
$stmt->execute();

printf("%d Row inserted.\n", maxdb_stmt_affected_rows($stmt));

$arr[0] = 22222;
$arr[1] = 'New Orleans';
$arr[2] = 'LA';

/* execute prepared statement */
$stmt->execute();

printf("%d Row inserted.\n", $stmt->affected_rows);

/* close statement and connection */
$stmt->close();

$result = $maxdb->query("SELECT * from temp.mycity WHERE zip = '11111' OR zip = '22222'");
if ($result) {
  while ($row = $result->fetch_row()) {
    printf ("%s %s %s\n", $row[0], $row[1], $row[2]);
  }
}

/* Clean up table CountryLanguage */
$maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'");
$maxdb->query("DELETE FROM temp.mycity WHERE name='New Orleans'");
printf("%d Rows deleted.\n", $maxdb->affected_rows);

/* close connection */
$maxdb->close();
?>

The above examples would produce the following output:

1 Row inserted.
1 Row inserted.
11111 Georgetown NY
22222 New Orleans LA
2 Rows deleted.
