The optdiag command displays statistics for tables, indexes, and columns, including the size of tables and indexes. If you are engaged in query tuning, optdiag provides the best tool for viewing all the statistics that you need. Here is a sample report for the titles table in the pubtune database:
Table owner: "dbo" Statistics for table: "titles" Data page count: 662 Empty data page count: 10 Data row count: 4986.0000000000000000 Forwarded row count: 18.0000000000000000 Deleted row count: 87.0000000000000000 Data page CR count: 86.0000000000000000 OAM + allocation page count: 5 First extent data pages: 3 Data row size: 238.8634175691937287
