Which SQL function is used to count the number of rows in a SQL query?
The SQL COUNT() function returns the number of rows in a table satisfying the criteria specified in the WHERE clause. It sets the number of rows or non NULL column values. COUNT() returns 0 if there were no matching rows. The above syntax is the general SQL 2003 ANSI standard syntax.
What will happen if you don’t specify ASC or DESC after a SQL order by clause?
If you don’t explicitly specify ASC or DESC , SQL Server uses ASC as the default sort order. Also, SQL Server treats NULL as the lowest values. When processing the SELECT statement that has an ORDER BY clause, the ORDER BY clause is the very last clause to be processed.
How do you order two things in SQL?
After the ORDER BY keyword, add the name of the column by which you’d like to sort records first (in our example, salary). Then, after a comma, add the second column (in our example, last_name ). You can modify the sorting order (ascending or descending) separately for each column.
