results::meta

Returns metadata about the columns in the query.

Synopsis
metadata_collection_view
meta() const;
Description

The returned collection will have as many metadata objects as columns retrieved by the SQL query, and in the same order.

For operations returning more than one resultset, returns metadata for the first resultset.

Preconditions

this->has_value() == true

Exception safety

No-throw guarantee.

Object lifetimes

This function returns a view object, with reference semantics. The returned view points into memory owned by *this, and will be valid as long as *this or an object move-constructed from *this are alive.

Complexity

Constant.
