# mysqli_stmt_execute

(PHP 5)

mysqli_stmt_execute

(no version information, might be only in CVS)

stmt->execute() -- Executes a prepared Query

## Descrição

Procedural style:

bool mysqli_stmt_execute ( mysqli_stmt stmt )

Object oriented style (method):

class mysqli_stmt {
bool execute ( void )
}

Executes a query that has been previously prepared using the mysqli_prepare() function. 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_stmt_fetch() function is used.

> Nota: When using mysqli_stmt_execute(), the mysqli_stmt_fetch() function must be used to fetch the data prior to performing any additional queries.

## Parâmetros

`stmt`

  Apenas para estilo de procedimento: Um identificador de statement retornado por mysqli_stmt_init().

## Valores de retornado

Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas.

## Exemplos

Exemplo 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(); ?>`

Exemplo 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); ?>`

O exemplo acima irá imprimir:

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