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 (or coercible to data.frame).

...

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

For dbBind(), a list of values, named or unnamed, or a data frame, with one element/column per query parameter. For dbBindArrow(), values as a nanoarrow stream, with one column per query parameter.

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?

object

Any R object
