Arguments

conn	A DBIConnection object, as returned by dbConnect().
name	The table name, passed on to dbQuoteIdentifier(). Options are: a character string with the unquoted DBMS table name, e.g. "table_name", a call to Id() with components to the fully qualified table name, e.g. Id(schema = "my_schema", table = "table_name") a call to SQL() with the quoted and fully qualified table name given verbatim, e.g. SQL('"my_schema"."table_name"')
value	A data frame of values. The column names must be consistent with those in the target table in the database.
...	Other parameters passed on to methods.
row.names	Whether the row.names of the data.frame should be preserved
dbObj	A object inheriting from DBIDriver or DBIConnection
obj	An R object whose SQL type we want to determine.
statement	a character string containing SQL.
params	A list of bindings, named or unnamed.
arrow	Whether the query should be returned as an Arrow Table
overwrite	If a table with the given name already exists, should it be overwritten?
append	If a table with the given name already exists, just try to append the passed data to it
field.types	Override the auto-generated SQL types
temporary	Should the created table be temporary?
