Easier to copy paste:

SELECT count(*) TABLES, concat(round(sum(table_rows)/1000000,2),’M') rows, concat(round(sum(data_length)/(1024*1024*1024),2),’G') DATA, concat(round(sum(index_length)/(1024*1024*1024),2),’G') idx,
concat(round(sum(data_length+index_length)/(1024*1024*1024),2),’G') total_size, round(sum(index_length)/sum(data_length),2) idxfrac
FROM information_schema.TABLES;

Another vote for putting the queries on one line for copy and pasting.
