Insert Data Into MySQL Using MySQLi and PDO

After a database and a table have been created, we can start adding data in them.

Here are some syntax rules to follow:

  • The SQL query must be quoted in PHP
  • String values inside the SQL query must be quoted
  • Numeric values must not be quoted
  • The word NULL must not be quoted

The INSERT INTO statement is used to add new records to a MySQL table:

INSERT INTO table_name (column1, column2, column3,…)
VALUES (value1, value2, value3,…)

In the previous chapter we created an empty table named “MyGuests” with five columns: “id”, “firstname”, “lastname”, “email” and “reg_date”. Now, let us fill the table with data.

Note: If a column is AUTO_INCREMENT (like the “id” column) or TIMESTAMP (like the “reg_date” column), it is no need to be specified in the SQL query; MySQL will automatically add the value.

The following examples add a new record to the “MyGuests” table:

Example (MySQLi Object-oriented)

Example (MySQLi Procedural)

Example (PDO)
