Value
dbListFields()
returns a character vector
that enumerates all fields
in the table in the correct order.
This also works for temporary tables if supported by the database.
The returned names are suitable for quoting with dbQuoteIdentifier().
If the table does not exist, an error is raised.
Invalid types for the name argument
(e.g., character of length not equal to one,
or numeric)
lead to an error.
An error is also raised when calling this method for a closed
or invalid connection.
See also
dbColumnInfo() to get the type of the fields.
