Arguments

...

Other arguments to methods.

object

Any R object

dbObj

An object inheriting from '>DBIObject, i.e. '>DBIDriver, '>DBIConnection, or a '>DBIResult

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.

A character vector to quote as string.

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

a logical specifying whether to overwrite an existing table or not. Its default is FALSE.

append

a logical specifying whether to append to an existing table in the DBMS. Its default is FALSE.

field.types, temporary

Ignored. Included for compatibility with generic.

row.names

A logical specifying whether the row.names should be output to the output DBMS table; if TRUE, an extra field whose name will be whatever the R identifier "row.names" maps to the DBMS (see DBI::make.db.names()). If NA will add rows names if they are characters, otherwise will ignore.

res

An object inheriting from '>DBIResult.

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.
