mysqli_stmt_execute

(PHP 5)

mysqli_stmt_execute

(no version information, might be only in CVS)

stmt->execute -- Executes a prepared Query

Description

Процедурный стиль:

bool mysqli_stmt_execute ( mysqli_stmt stmt )

Объектно-ориентированный стиль (method):

class mysqli_stmt {

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.

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

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
