Second, connect to the MySQL database server using the connect.php script.First, define an array that holds the SQL statements for creating the authors and book_authors tables.Note that this script reuses the connect.php script that creates a connection to the MySQL database server. The following script illustrates how to create the authors and book_authors tables: exec($statement) The exec() method returns the number of affected rows on success or false on failure. Second, execute an SQL statement by calling the exec() method of the PDO instance.First, connect to the database (MySQL server in this case) by creating a new instance of the PDO class.To execute an SQL statement using PDO, you use follow these steps: However, in this tutorial, you will learn how to create them from PHP using PDO. Typically, you execute these CREATE TABLE statements using a MySQL client tool to create the authors and book_authors tables. Note that the book_authors table links to the books created from the previous tutorial. REFERENCES authors(author_id) ON DELETE CASCADE REFERENCES books(book_id) ON DELETE CASCADE, ) Code language: SQL (Structured Query Language) ( sql )Īnd the following CREATE TABLE statement creates the book_authors table: CREATE TABLE book_authors ( For example, the following CREATE TABLE statement creates the authors table: CREATE TABLE authors( To create a new table in a database, you use the CREATE TABLE statement. We will work on ‘pencil_db’ which currently has the following tables.Summary: in this tutorial, you wil learn how to create new tables in the database using PDO. Let’s see some examples in MySQL for better understanding. LIKE statement preserves the database objects such as indexes, primary key, foreign key constraints, triggers, etc., associated with the table. LIKE statement in MySQL can create a new table from another table but the main difference between them is that CREATE TABLE. Where LIMIT 0 is used to create an empty table otherwise, all the data will also be copied along with the table definition.īoth, CREATE TABLE. Note: Syntax within square brackets is optional. To create a TEMPORARY destination table, use: CREATE TEMPORARY TABLE new_table LIKE original_table Īnother approach of creating a table from another is by adding a SELECT statement at the end of the CREATE TABLE statement: CREATE TABLE new_table LIKE will not create a temporary table irrespective of the fact whether the original table is a temporary table or not. LIKE works only for base tables, not for views.Īlso, It is important to note that CREATE TABLE. In order to create a table based on another table, SELECT privilege is required on the original table. The above MySQL statement creates an empty table based on the definition of the original table, including any column attributes and indexes defined in the original table.
