dbCreateTable() returns TRUE, invisibly.

Failure modes

If the table exists, an error is raised; the remote table remains unchanged.

An error is raised when calling this method for a closed or invalid connection. An error is also raised if name cannot be processed with dbQuoteIdentifier() or if this results in a non-scalar. Invalid values for the row.names and temporary arguments (non-scalars, unsupported data types, NA, incompatible values, duplicate names) also raise an error.

Additional arguments

The following arguments are not part of the dbCreateTable() generic (to improve compatibility across backends) but are part of the DBI specification:

  • temporary (default: FALSE)

They must be provided as named arguments. See the "Specification" and "Value" sections for details on their usage.


The name argument is processed as follows, to support databases that allow non-syntactic names for their objects:

  • If an unquoted table name as string: dbCreateTable() will do the quoting, perhaps by calling dbQuoteIdentifier(conn, x = name)

  • If the result of a call to dbQuoteIdentifier(): no more quoting is done

If the temporary argument is TRUE, the table is not available in a second connection and is gone after reconnecting. Not all backends support this argument. A regular, non-temporary table is visible in a second connection, in a pre-existing connection, and after reconnecting to the database.

SQL keywords can be used freely in table names, column names, and data. Quotes, commas, and spaces can also be used for table names and column names, if the database supports non-syntactic identifiers.

The row.names argument must be missing or NULL, the default value. All other values for the row.names argument (in particular TRUE, NA, and a string) raise an error.
