Description Usage Arguments Value See Also Examples

Description

Returns the unquoted names of remote tables accessible through this connection. This should include views and temporary objects, but not all database backends (in particular RMariaDB and RMySQL) support this.

Usage

Arguments

conn

A DBIConnection object, as returned by dbConnect().

...

Other parameters passed on to methods.

Value

dbListTables() returns a character vector that enumerates all tables and views in the database. Tables added with dbWriteTable() are part of the list. As soon a table is removed from the database, it is also removed from the list of database tables.

The same applies to temporary tables if supported by the database.

The returned names are suitable for quoting with dbQuoteIdentifier(). An error is raised when calling this method for a closed or invalid connection.
