spec_sql_list_fields

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.

Specification

The name argument can be

  • a string

  • the return value of dbQuoteIdentifier()

  • a value from the table column from the return value of dbListObjects() where is_prefix is FALSE

A column named row_names is treated like any other column.
