Returns metadata about the columns in the query.

meta() const;

The returned collection will have as many metadata objects as columns retrieved by the SQL query, and in the same order. Note that this may not be the same order as in the StaticRow type, since columns may be mapped by name or discarded. This function returns the representation that was retrieved from the database.

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.
