plz help with the following: Change the following commands to oracle commands line meaning that they would be able to create the tables and their relationships when used on oracle live sql or oracle sql developper, CREATE TABLE `book`( `num` INT(20) NOT NULL AUTO_INCREMENT, `title` VARCHAR(20), `year` DATE, `subject` VARCHAR(20), `checkedout` DATETIME, `checkedin` DATETIME, PRIMARY KEY (`num`) ); CREATE TABLE `client`( `CID` INT(20) NOT NULL AUTO_INCREMENT, `fname` VARCHAR(25), `lname` VARCHAR(25), `type` VARCHAR(25), `num` INT(20), PRIMARY KEY (`CID`), FOREIGN KEY (`num`) REFERENCES `emp`.`state`(`state_id`) ); CREATE TABLE `author`( `id` INT(10) NOT NULL AUTO_INCREMENT, `year` DATE, `fName` VARCHAR(20), `lname` VARCHAR(20), `num` INT(20), PRIMARY KEY (`id`) ); ALTER TABLE `author` ADD FOREIGN KEY (`num`) REFERENCES `book`(`num`); ALTER TABLE `client` ADD CONSTRAINT `client_ibfk_1` FOREIGN KEY (`num`) REFERENCES `book`(`num`);
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
