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

Description

dbExecute comes with a default implementation (which should work with most backends) that calls dbSendStatement, then dbGetRowsAffected, ensuring that the result is always free-d by dbClearResult.

Usage

dbExecute(conn, statement, ...)

Arguments

Value

The number of rows affected by the statement

Examples

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

dbWriteTable(con, "cars", head(cars, 3))
dbReadTable(con, "cars")   # there are 3 rows
dbExecute(con,
  "INSERT INTO cars (speed, dist) VALUES (1, 1), (2, 2), (3, 3);")
dbReadTable(con, "cars")   # there are now 6 rows

dbDisconnect(con)
