Introduction to SQL Server ROW_NUMBER() function. 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. COUNT is more interestingly used along with GROUP BY to get the counts of specific information. USE AdventureWorks2012; GO SELECT count(*) AS Count FROM Production.ProductInventory WHERE Quantity < 300; GO Here is the result set. The ROW_NUMBER() function can be used for pagination.
