...CMIS102 Homework Assignment 3 Problem definition: Write a program that would calculate and display the results for the multiplication table for values ranging from 1 to 100. A. Problem Analysis – Following the directions in the assignment, clearly write up your problem analysis in this section. In order to write this program, two variables, ROWNUM and COLUMNNUM, will be used with nested repetition loop to complete the necessary calculations. ROWNUM will be used in an outerloop and contain numbers between1-10 and COLUMNNUM will be used in an innerloop and contain numbers between 1-10. For each iteration of the outerloop, the inner loop will be executed 10 times and the product of ROWNUM*COLUMNNUM will produce the multiplication table of ROWNUM. The ROWNUM and COLUMNNUM variables will be incremented by 1in each iteration of loops. The new line will be printed to display the multiplication table for each value of ROWNUM in a separate line. This table shows the outputs that will be generated from the calculations: 1 2 3 4 5 6 7 8 9 10 2 4 6 8 10 12 14 16 18 20 3 6 9 12 15 18 21 24 27 30 4 8 12 16 20 24 28 32 36 40 5 10 15 20 25 30 35 40 45 50 6 12 18 24 30 36 42 48 54 60 7 14 21 28 35 42 49 56 63 70 8 16 24 32 40 48 56 64 72 80 9 18 27 36 45 54 63 72 81 90 10 20 30 40 50 60 70 80 90 100 B.

...Join in SQL SQL Join is used to fetch data from two or more tables, which is joined to appear as single set of data. SQL Join is used for combining column from two or more tables by using values common to both tables. JoinKeyword is used in SQL queries for joining two or more tables. Minimum required condition for joining table, is(n-1) where n, is number of tables. A table can also join to itself known as, Self Join. Types of Join The following are the types of JOIN that we can use in SQL. * Inner * Outer * Left * Right Cross JOIN or Cartesian Product This type of JOIN returns the cartesian product of rows from the tables in Join. It will return a table which consists of records which combines each row from the first table with each row of the second table. Cross JOIN Syntax is, SELECT column-name-list from table-name1 CROSS JOIN table-name2; Example of Cross JOIN The class table, ID | NAME | 1 | abhi | 2 | adam | 4 | alex | The class_info table, ID | Address | 1 | DELHI | 2 | MUMBAI | 3 | CHENNAI | Cross JOIN query will be, SELECT * from class, cross JOIN class_info; The result table will look like, ID | NAME | ID | Address | 1 | abhi | 1 | DELHI | 2 | adam | 1 | DELHI | 4 | alex | 1 | DELHI | 1 | abhi | 2 | MUMBAI | 2 | adam | 2 | MUMBAI | 4 | alex | 2 | MUMBAI | 1 | abhi | 3 | CHENNAI | ...

...query. Queries allow you to retrieve information from one or more tables based on a set of search conditions you define. Access 2007 will display your results in their very own table that you can analyze and manipulate further. This lesson will explain how to plan a query using a three-question planning process. You will learn how to use the Query Design command to run the query, as well as how to modify the query to hide fields or other information in your query results. Finally, it will show you how to save the query for later use. Using Queries Queries retrieve information from one or more tables based on a set of search conditions that you set up and then combine that information in a way that is easy for you to analyze. If you have used an Advanced Filter in Access 2007, then you have already run a very basic query on only one table. If you want to pull data from more than one table, though, you will need to use either the Query Design command or the Query Wizard. Before using the Access 2007 query tools, it is important to plan out the query using a logical process. Otherwise, you may not get the results you expect. Planning a Query There are three questions you need to answer when you are planning a query: What do you want the results to look like? Identify every field or bit of information that you want included in the results. Where is the information stored in the database? List which tables (and/or queries) hold the information that you want to see. ...

Establish referential integrity using SQL. Discuss the SQL:1999 and SQL:2008 standards. INTRODUCTION Pronounced “S-Q-L” by some and “sequel” by others, SQL has become the de facto standard language for creating and querying relational databases. (Can the next standard be the sequel to SQL?) The primary purpose of this chapter is to introduce SQL, the most common language for relational systems. It has been accepted as a U.S. standard by the American National Standards Institute (ANSI) and is a Federal Information Processing Standard (FIPS). It is also an international standard recognized by the International Organization for Standardization (ISO). ANSI has accredited the International Committee for Information Technology Standards (INCITS) as a standards development organization; INCITS is working on the next version...

...DB2 & SQL Concepts 1.2.1 What is SQL? Structured Query Language (SQL) is a standardized language for defining and manipulating data in a relational database. In accordance with the relational model of data, the database is perceived as a set of tables, relationships are represented by values in tables, and data is retrieved by specifying a result table that can be derived from one or more tables. DB2 transforms the specification of a result table into a sequence of internal operations that optimize data retrieval. This transformation occurs when the SQL statement is prepared. This transformation is also known as binding. 1.2.2 Static SQL The source form of a static SQL statement is embedded within an application program written in a host language such as COBOL. The statement is prepared before the program is executed and the operational form of the statement persists beyond the execution of the program. A source program containing static SQL statements must be processed by an SQL precompiler before it is compiled. The precompiler checks the syntax of the SQL statements, turns them into host language comments, and generates host language statements to invoke DB2. 1.2.3 Dynamic SQL A dynamic SQL statement is prepared during the execution of an SQL application, and the operational form of the statement is not persistent. The source form of the statement is a character string...

...value for the specified attribute, but count considers null values. As an example, we can find the highest low-temperature reading anywhere with Execute the following query using postgreSQL and see the results: SELECT max(temp_lo) FROM weather; Note: The aggregate max cannot be used in the WHERE clause (This restriction exists because the WHERE clause determines the rows that will go into the aggregation stage; so it has to be evaluated before aggregate functions are computed.) Aggregates are also very useful in combination with GROUP BY clauses. For example, we can get the maximum low temperature observed in each city with Execute the following query using postgreSQL and see the results: SELECT city, max(temp_lo) FROM weather GROUP BY city; which gives us one output row per city. Each aggregate result is computed over the table rows matching that city. We can filter these grouped rows using HAVING: Execute the following query using postgreSQL and see the results: SELECT city, max(temp_lo) FROM weather GROUP BY city HAVING max(temp_lo) < 40; which gives us the same results for only the cities that have all temp_lo values below 40. Finally, if we only care about cities whose names begin with “S”, we might do Execute the following query using postgreSQL and see the results: SELECT city, max(temp_lo) FROM weather WHERE city LIKE ’S%’ GROUP BY city Begum Durgahee HAVING max(temp_lo) < 40; 1 Labsheet02 PostgreSQL7.4 The...
