| In: |
lib/sequel/dataset/prepared_statements.rb

Default implementation of the argument mapper to allow native database support for bind variables and prepared statements (as opposed to the emulated ones used by default).
| SQL_QUERY_TYPE | = | Hash.new{|h,k| h[k] = k} |
| bind_arguments | [RW] | The bind arguments to use for running this prepared statement |
| prepared_statement_name | [RW] | The name of the prepared statement, if any. |
Override the given *_sql method based on the type, and cache the result of the sql.
