maxdb_stmt_bind_param
maxdb_stmt::bind_param
(PECL maxdb >= 1.0) maxdb_stmt_bind_param -- maxdb_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 &$...
] )
bool maxdb_stmt::bind_param
( string $types
, mixed &$var1
[, mixed &$...
] )
bool maxdb_stmt_bind_param
( resource $stmt
, string $types
, array &$var
)
bool maxdb_stmt::bind_param
( string $types
, array &$var
)
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 an 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().
Type specification chars
| Character |
Description |
| i |
corresponding variable has type integer |
| d |

| s |
corresponding variable has type string |
| b |

Examples
Example #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();
?>
Example #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 example will output
something similar to:
1 Row inserted.
1 Row deleted.
Example #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 example will output
something similar to:
Example #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 example will output
something similar to:
Example #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 example will output
something similar to:
1 Row inserted.
1 Row inserted.
11111 Georgetown NY
22222 New Orleans LA
2 Rows deleted.
