To insert data into a PostgreSQL database, you can use the INSERT statement. This statement allows you to insert one or more rows into a table in the database. For example, if you have a table named users with columns id, name, and email, you can insert a new row into the table using the following INSERT statement:
INSERT INTO users (id, name, email)
VALUES (1, 'John Doe', 'johndoe@example.com');
This statement will insert a new row into the users table with the specified values for the id, name, and email columns. You can insert multiple rows into the table by specifying multiple sets of values in the VALUES clause, separated by commas. For example:
INSERT INTO users (id, name, email)
VALUES (1, 'John Doe', 'johndoe@example.com'),
(2, 'Jane Doe', 'janedoe@example.com'),
(3, 'John Smith', 'johnsmith@example.com');
This statement will insert three new rows into the users table. It is important to note that the order of the values in the VALUES clause must match the order of the columns in the INSERT statement.
Overall, the INSERT statement is the primary way to insert data into a PostgreSQL database. It allows you to insert one or more rows into a table, and provides a flexible and powerful way to add data to your database.
