MySQLi – Create Table ”; Previous Next To begin with, the table creation command requires the following details − Name of the table Name of the fields Definitions for each field Syntax Here is a generic SQL syntax to create a MySQL table − CREATE TABLE table_name (column_name column_type); Now, we will create the following table in the TUTORIALS database. create table tutorials_tbl( tutorial_id INT NOT NULL AUTO_INCREMENT, tutorial_title VARCHAR(100) NOT NULL, tutorial_author VARCHAR(40) NOT NULL, submission_date DATE, PRIMARY KEY ( tutorial_id ) ); Here, a few items need explanation − Field Attribute NOT NULL is being used because we do not want this field to be NULL. So, if a user will try to create a record with a NULL value, then MySQL will raise an error. Field Attribute AUTO_INCREMENT tells MySQL to go ahead and add the next available number to the id field. Keyword PRIMARY KEY is used to define a column as a primary key. You can use multiple columns separated by a comma to define a primary key. Creating Tables from Command Prompt It is easy to create a MySQL table from the mysql> prompt. You will use the SQL command CREATE TABLE to create a table. Example Here is an example, which will create tutorials_tbl − root@host# mysql -u root -p Enter password:******* mysql> use TUTORIALS; Database changed mysql> CREATE TABLE tutorials_tbl( → tutorial_id INT NOT NULL AUTO_INCREMENT, → tutorial_title VARCHAR(100) NOT NULL, → tutorial_author VARCHAR(40) NOT NULL, → submission_date DATE, → PRIMARY KEY ( tutorial_id ) → ); Query OK, 0 rows affected (0.16 sec) mysql> NOTE − MySQL does not terminate a command until you give a semicolon (;) at the end of SQL command. Creating Tables Using PHP Script PHP uses mysqli query() or mysql_query() function to create a MySQL table. This function takes two parameters and returns TRUE on success or FALSE on failure. Syntax $mysqli→query($sql,$resultmode) Sr.No. Parameter & Description 1 $sql Required – SQL query to create a MySQL table. 2 $resultmode Optional – Either the constant MYSQLI_USE_RESULT or MYSQLI_STORE_RESULT depending on the desired behavior. By default, MYSQLI_STORE_RESULT is used. Example Try the following example to create a table − Copy and paste the following example as mysql_example.php − <html> <head> <title>Creating MySQL Table</title> </head> <body> <?php $dbhost = ”localhost”; $dbuser = ”root”; $dbpass = ”root@123”; $dbname = ”TUTORIALS”; $mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname); if($mysqli→connect_errno ) { printf(“Connect failed: %s<br />”, $mysqli→connect_error); exit(); } printf(”Connected successfully.<br />”); $sql = “CREATE TABLE tutorials_tbl( “. “tutorial_id INT NOT NULL AUTO_INCREMENT, “. “tutorial_title VARCHAR(100) NOT NULL, “. “tutorial_author VARCHAR(40) NOT NULL, “. “submission_date DATE, “. “PRIMARY KEY ( tutorial_id )); “; if ($mysqli→query($sql)) { printf(“Table tutorials_tbl created successfully.<br />”); } if ($mysqli→errno) { printf(“Could not create table: %s<br />”, $mysqli→error); } $mysqli→close(); ?> </body> </html> Output Access the mysql_example.php deployed on apache web server and verify the output. Connected successfully. Table tutorials_tbl created successfully. Print Page Previous Next Advertisements ”;
