SQL: SQL stands for “Structured Query Language”. The current version of SQL is “ANSI SQL – 92”. It contains constructs which are used to define and process database . They are executed using DBMS-supplied command prompt. SQL is not a programming language. It is text-based and it is also called as data sublanguage. In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on. Table Creation: Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows: CREATE TABLE TABLE_NAME ( Column1 datatype, Column2 datatype, … ); JOIN ON Syntax: The “JOIN ON” syntax is usually used to join two or more than two tables. This syntax usually works with “WHERE” clause. The keyword “JOIN” is normally placed between the table names in the SQL FROM clause. The keyword “ON” includes the matching key values.

Program Plan Intro

SQL:

SQL stands for “Structured Query Language”.

The current version of SQL is “ANSI SQL – 92”.

It contains constructs which are used to define and process database. They are executed using DBMS-supplied command prompt.

SQL is not a programming language. It is text-based and it is also called as data sublanguage. In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.

Table Creation:

Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows:

CREATE TABLE TABLE_NAME (

Column1 datatype,

Column2 datatype,

…

);

JOIN ON Syntax:

The “JOIN ON” syntax is usually used to join two or more than two tables. This syntax usually works with “WHERE” clause. The keyword “JOIN” is normally placed between the table names in the SQL FROM clause. The keyword “ON” includes the matching key values.

Specifications: Part-1Part-1: DescriptionIn this part of the lab you will build a single operation ALU. This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle.Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…
