Group by schema name(schema id), [tables].name; when you run this query, it will give you following result, which is pretty accurate and much faster than going over every single table to find the row count. I found the post "mysql: fastest way to count number of rows" on stack overflow, which looked like it would solve my problem. bayuah provided this answer: table rows "rows count" from . information schema.tables. where . table name="table name" and . table schema="database name";. Here we use the count() function and the group by clause, to return the number of records for each category in the products table: you will learn more about the group by clause later in this tutorial. The t sql query below uses the coalesce () function to iterate through each of the tables to dynamically build a query to capture the row count from each of the tables (individual count queries combined using union all) and provides the row counts for all the tables in a database.
