Arguments

object	Any R object
drv	an object that inherits from DBIDriver, or an existing DBIConnection object (in order to clone an existing connection).
...	authentication arguments needed by the DBMS instance; these typically include user, password, host, port, dbname, etc. For details see the appropriate DBIDriver.
dbObj	A object inheriting from DBIDriver or DBIConnection
obj	An R object whose SQL type we want to determine.
conn	A DBIConnection object, as returned by dbConnect().
statement	a character string containing SQL.
x	A character vector to quote as string.
res	An object inheriting from DBIResult.
n	maximum number of records to retrieve per fetch. Use n = -1 or n = Inf to retrieve all pending records. Some implementations may recognize other special values.
params	A list of bindings, named or unnamed.
name	A character string specifying the unquoted DBMS table name, or the result of a call to dbQuoteIdentifier().
value	a data.frame (or coercible to data.frame).
overwrite	Allow overwriting the destination table. Cannot be 'TRUE' if 'append' is also 'TRUE'.
append	Allow appending to the destination table. Cannot be 'TRUE' if 'overwrite' is also 'TRUE'.
