Method: Sequel::MySQL::Dataset#split_multiple_result_sets

Defined in:
lib/sequel/adapters/mysql.rb

#split_multiple_result_sets ⇒ Object

Makes each yield arrays of rows, with each array containing the rows for a given result set. Does not work with graphing. So you can submit SQL with multiple statements and easily determine which statement returned which results.

Modifies the row_proc of the returned dataset so that it still works as expected (running on the hashes instead of on the arrays of hashes). If you modify the row_proc afterward, note that it will receive an array of hashes instead of a hash.

Raises:
