An RDBMS performs the following steps: 1)It calculates the results of the group functions of each group. 2)It groups those rows together based on the group by clause. 3)It orders the groups based on the results of the group functions in the order by clause. 4)It chooses and eliminates groups based on the having clause On some platforms (e.g. PostgreSQL, Oracle, T-SQL) this can be done directly using window functions: select * from ( select *, row_number () over (partition by field1 order by field2) as row_number from table ) as rows where row_number = 1. On others (MySQL, SQLite), you'll need to write subqueries that will make you join the entire table with. Write a query that displays the last name (with the first letter uppercase and all other letters lowercase) and the length of the last name for all employees whose name starts with the letters J, A, or M. Give each column an appropriate label. Sort the results by the employees' last names. Sample output: Name Length

This is a simple JOIN in which the result is based on matched data as per the equality condition specified in the SQL query. Inner Join Syntax is, SELECT column-name-list FROM table-name1 INNER JOIN table-name2 WHERE table-name1.column-name = table-name2.column-name; Example of INNER JOIN. Consider a class table Query order of execution. 1. FROM and JOIN s. The FROM clause, and subsequent JOIN s are first executed to determine the total working set of data that is being queried. This includes subqueries in this clause, and can cause temporary tables to be created under the hood containing all the columns and rows of the tables being joined Also show the result of each query if applied to the database of Figure 6.6. Answers: In the relational algebra, as in other languages, it is possible to specify the same query in multiple ways. We give one possible solution for each query. We use the symbol σ for SELECT, Π for PROJECT, ϑ for EQUIJOIN, * for NATURAL JOIN, and f for FUNCTION To eliminate the duplicate rows, the database system sorts the combined result set by every column and scans it for the matching rows located next to one another. To retain the duplicate rows in the result set, you use the UNION ALL operator. Suppose, we have two result sets A(1,2) and B(2,3). The following picture illustrates A UNION B 1 Points for this page: _____ I. Query Languages (30 points).
