CONCAT( ROUND( table_rows / 1000000, 4 ), 'M' ) AS 'Number of Rows',

CONCAT( ROUND( data_length / ( 1024 * 1024 * 1024 ), 4 ), 'G' ) AS 'Data Size',

CONCAT( ROUND( index_length / ( 1024 * 1024 * 1024 ), 4 ), 'G' ) AS 'Index Size',

CONCAT( ROUND( ( data_length + index_length ) / ( 1024 * 1024 * 1024 ), 4 ), 'G' ) AS 'Total'

FROM
