Public Instance methods

call(type, bind_arguments={}, *values, &block)

MySQL is different in that it supports prepared statements but not bound variables outside of prepared statements. The default implementation breaks the use of subselects in prepared statements, so extend the temporary prepared statement that this creates with a module that fixes it.
