mysqli_stmt::attr_set -- mysqli_stmt_attr_set — Used to modify the behavior of a prepared statement

### Opis

Styl obiektowy

bool mysqli_stmt::attr_set ( int `$attr` , int `$mode` )

Styl proceduralny

bool mysqli_stmt_attr_set ( mysqli_stmt `$stmt` , int `$attr` , int `$mode` )

Used to modify the behavior of a prepared statement. This function may be called multiple times to set several attributes.

### Parametry

`stmt`

  Tylko styl proceduralny: Identyfikator stanu zwrócony przez mysqli_stmt_init().

`attr`

  The attribute that you want to set. It can have one of the following values:

  Attribute values
  Character | Description
  --- | ---
  MYSQLI_STMT_ATTR_UPDATE_MAX_LENGTH | If set to 1, causes mysqli_stmt_store_result() to update the metadata MYSQL_FIELD->max_length value.
  MYSQLI_STMT_ATTR_CURSOR_TYPE | Type of cursor to open for statement when mysqli_stmt_execute() is invoked. `mode` can be MYSQLI_CURSOR_TYPE_NO_CURSOR (the default) or MYSQLI_CURSOR_TYPE_READ_ONLY.
  MYSQLI_STMT_ATTR_PREFETCH_ROWS | Number of rows to fetch from server at a time when using a cursor. `mode` can be in the range from 1 to the maximum value of unsigned long. The default is 1.

  If you use the MYSQLI_STMT_ATTR_CURSOR_TYPE option with MYSQLI_CURSOR_TYPE_READ_ONLY, a cursor is opened for the statement when you invoke mysqli_stmt_execute(). If there is already an open cursor from a previous mysqli_stmt_execute() call, it closes the cursor before opening a new one. mysqli_stmt_reset() also closes any open cursor before preparing the statement for re-execution. mysqli_stmt_free_result() closes any open cursor.

  If you open a cursor for a prepared statement, mysqli_stmt_store_result() is unnecessary.

`mode`

  The value to assign to the attribute.
