results::out_params

Returns the output parameters of a stored procedure call.

Synopsis
row_view
out_params() const noexcept;
Description

Relevant for CALL operations performed using prepared statements that bind placeholders to OUT or INOUT parameters. Returns a row containing a field per bound output parameter.

If this operation had no output parameters (e.g. it wasn't a CALL), returns an empty row.

Preconditions

this->has_value() == true

Exception safety

No-throw guarantee.

Object lifetimes

The returned reference and any other references obtained from it are valid as long as *this is alive. Move operations invalidate references.

Complexity

Linear on this->size().
