dbExecute: Execute an update statement, query number of rows affected, and then close result set

Usage

dbExecute(conn, statement, ...)

Arguments

A DBIConnection object, as produced by dbConnect.

statement

a character vector of length 1 containing SQL.

...

Other parameters passed on to methods.

Examples

con <- dbConnect(RSQLite::SQLite(), ":memory:")

dbWriteTable(con, "cars", head(cars, 3))
