Execute a statement on a given database connection
}
\description{
These methods are straight-forward implementations of the corresponding
generic functions.
However, for complex data like array are just transferred as a string instead of the corresponding
vector in R. This behavior will change in future releases, and the author is advised not to rely on it.
