# maxdb_stmt_execute

# maxdb_stmt::execute

(PECL maxdb >= 1.0)

maxdb_stmt_execute -- maxdb_stmt::execute — Executes a prepared Query

### Description

Procedural style

bool maxdb_stmt_execute ( resource `$stmt` )

Object oriented style

bool maxdb_stmt::execute ( void )

The maxdb_stmt_execute() function executes a query that has been previously prepared using the maxdb_prepare() function represented by the `stmt` resource. When executed any parameter markers which exist will automatically be replaced with the appropiate data.

If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the maxdb_stmt_affected_rows() function. Likewise, if the query yields a result set the maxdb_fetch() function is used.

> Note:

> When using maxdb_stmt_execute(), the maxdb_fetch() function must be used to fetch the data prior to preforming any additional queries.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### 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");
/* Prepare an insert statement */
$query = "INSERT INTO temp.mycity (zip, name, state) VALUES (?,?,?)";
$stmt = $maxdb->prepare($query);
$stmt->bind_param("sss", $val1, $val2, $val3);
$val1 = '11111';
$val2 = 'Georgetown';
$val3 = 'NY';
/* Execute the statement */
$stmt->execute();
$val1 = '22222';
$val2 = 'Hubbatown';
$val3 = 'CA';
/* Execute the statement */
$stmt->execute();
/* close statement */
$stmt->close();
/* retrieve all rows from myCity */
$query = "SELECT zip, name, state FROM temp.mycity";
if ($result = $maxdb->query($query)) {
while ($row = $result->fetch_row()) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
/* free result set */
$result->close();
}
/* remove table */
$maxdb->query("DROP TABLE temp.mycity");
/* close connection */
$maxdb->close();
?>`

Example #2 Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
/* Prepare an insert statement */
$query = "INSERT INTO temp.mycity (zip, name, state) VALUES (?,?,?)";
$stmt = maxdb_prepare($link, $query);
maxdb_stmt_bind_param($stmt, "sss", $val1, $val2, $val3);
$val1 = '11111';
$val2 = 'Georgetown';
$val3 = 'NY';
/* Execute the statement */
maxdb_stmt_execute($stmt);
$val1 = '22222';
$val2 = 'Hubbatown';
$val3 = 'CA';
/* Execute the statement */
maxdb_stmt_execute($stmt);
/* close statement */
maxdb_stmt_close($stmt);
/* retrieve all rows from myCity */
$query = "SELECT zip, name, state FROM temp.mycity";
if ($result = maxdb_query($link, $query)) {
while ($row = maxdb_fetch_row($result)) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
/* free result set */
maxdb_free_result($result);
}
/* remove table */
maxdb_query($link, "DROP TABLE temp.mycity");
/* close connection */
maxdb_close($link);
?>`

The above example will output something similar to:

    11111 (Georgetown,NY)
    22222 (Hubbatown,CA)
