Question: If the channels is wxyzrstuvpq, what is the horizontal order?
SQL: SELECT "horizontal_order" FROM "higher_order_b_format_channels" WHERE "channels"='WXYZRSTUVPQ';

Question: If the height order is 1 and the soundfield type is mixed-order, what are all the channels?
SQL: SELECT "channels" FROM "higher_order_b_format_channels" WHERE "soundfield_type"='mixed-order' AND "height_order"=1;

Question: If the channels is wxyzuv, what is the number of channels?
