stmt->execute -- Executes a prepared Query

Description

Procedural style:

bool mysqli_stmt_execute ( object stmt)

Object oriented style (method):

class mysql {

bool execute ( void )

}

The mysqli_stmt_execute() function executes a query that has been previously prepared using the mysqli_prepare() function represented by the stmt object. 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 mysqli_stmt_affected_rows() function. Likewise, if the query yields a result set the mysqli_fetch() function is used.

注: When using mysqli_stmt_execute(), the mysqli_fetch() function must be used to fetch the data prior to preforming any additional queries.

Return values

如果成功则返回 TRUE,失败则返回 FALSE

Example

例子 1. Object oriented style

<?php
$mysqli
= new mysqli("localhost", "my_user", "my_password", "world");
   
/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
   
$mysqli->query("CREATE TABLE myCity LIKE City");

/* Prepare an insert statement */
$query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)";
$stmt = $mysqli->prepare($query);

$stmt->bind_param("sss", $val1, $val2, $val3);

$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';
    
/* Execute the statement */
$stmt->execute();

$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';
    
/* Execute the statement */
$stmt->execute();

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

/* retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
if (
$result = $mysqli->query($query)) {
    while (
$row = $result->fetch_row()) {
        
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
    }
    
/* free result set */
    
$result->close();
}

/* remove table */
$mysqli->query("DROP TABLE myCity");

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

例子 2. Procedural style

<?php
$link
= mysqli_connect("localhost", "my_user", "my_password", "world");
   
/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
   
mysqli_query($link, "CREATE TABLE myCity LIKE City");

/* Prepare an insert statement */
$query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)";
$stmt = mysqli_prepare($link, $query);

mysqli_stmt_bind_param($stmt, "sss", $val1, $val2, $val3);

$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';
    
/* Execute the statement */
mysqli_stmt_execute($stmt);

$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';
    
/* Execute the statement */
mysqli_stmt_execute($stmt);

/* close statement */
mysqli_stmt_close($stmt);

/* retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
if (
$result = mysqli_query($link, $query)) {
    while (
$row = mysqli_fetch_row($result)) {
        
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
    }
    
/* free result set */
    
mysqli_free_result($result);
}

/* remove table */
mysqli_query($link, "DROP TABLE myCity");

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

The above examples would produce the following output:

Stuttgart (DEU,Baden-Wuerttemberg)
Bordeaux (FRA,Aquitaine)
