maxdb_stmt_bind_param
stmt->bind_param
(PECL maxdb:1.0-7.6.00.38) maxdb_stmt_bind_param -- 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 &$...
] )
stmt
bool
bind_param
( string $types
, mixed &$var1
[, mixed &$...
] )
Procedural style (extended syntax):
bool maxdb_stmt_bind_param
( resource $stmt
, string $types
, array &$var
)
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().

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.
