mysqli_stmt::execute
mysqli_stmt_execute
Executes a prepared statement
Description
Object-oriented style
public bool mysqli_stmt::execute(arraynull $params = null )
bool mysqli_stmt_execute(mysqli_stmt $statement , arraynull $params = null )
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. If the query yields a result set, it can be fetched using
mysqli_stmt_get_result function or by fetching it
row by row directly from the statement using
mysqli_stmt_fetch function.
Parameters
-
statement
-
Procedural style only: A mysqli_stmt object
returned by mysqli_stmt_init.
-
params
-
An optional list array with as many elements as there are bound parameters in the SQL statement being executed. Each value is treated as a string.
Return Values
Returns true on success or false on failure.
Errors/Exceptions
If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR ) and the requested operation fails,
a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT ,
a mysqli_sql_exception is thrown instead.
Examples
Example #1 Execute a prepared statement with bound variables
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$mysqli->query("CREATE TEMPORARY TABLE myCity LIKE City");
/* Prepare an insert statement */
$stmt = $mysqli->prepare("INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");
/* Bind variables to parameters */
$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();
/* Retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
$result = $mysqli->query($query);
while ($row = $result->fetch_row()) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");
/* Prepare an insert statement */
$stmt = mysqli_prepare($link, "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");
/* Bind variables to parameters */
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);
/* Retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
$result = mysqli_query($link, $query);
while ($row = mysqli_fetch_row($result)) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
The above examples will output:
Stuttgart (DEU,Baden-Wuerttemberg)
Bordeaux (FRA,Aquitaine)
Example #2 Execute a prepared statement with an array of values
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');
$mysqli->query('CREATE TEMPORARY TABLE myCity LIKE City');
/* Prepare an insert statement */
$stmt = $mysqli->prepare('INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)');
/* Execute the statement */
$stmt->execute(['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);
/* Retrieve all rows from myCity */
$query = 'SELECT Name, CountryCode, District FROM myCity';
$result = $mysqli->query($query);
while ($row = $result->fetch_row()) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'world');
mysqli_query($link, 'CREATE TEMPORARY TABLE myCity LIKE City');
/* Prepare an insert statement */
$stmt = mysqli_prepare($link, 'INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)');
/* Execute the statement */
mysqli_stmt_execute($stmt, ['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);
/* Retrieve all rows from myCity */
$query = 'SELECT Name, CountryCode, District FROM myCity';
$result = mysqli_query($link, $query);
while ($row = mysqli_fetch_row($result)) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
The above examples will output:
Stuttgart (DEU,Baden-Wuerttemberg)
