In this article, we would like to show you how to useĀ INSERT INTOĀ statementĀ in PostgreSQL.

Quick solution:

INSERT INTO "table_name"
    ("column1", "column2", "column3", ...)
VALUES
    ("value1", "value2", "value3", ...);

or:

INSERT INTO "table_name"
    ("column1", "column2", "column3", ...)
VALUES
    ("value1", "value2", "value3", ...),
    ("value1", "value2", "value3", ...),
    ("value1", "value2", "value3", ...),
    ...;

Ā 

Practical example

To show how the INSERT INTOĀ statementĀ works, we will use the following table:

PostgreSQL - example data used with INSERT INTO statement.
PostgreSQL - example data used with INSERT INTO statement.

Note:

At the end of this article you can find database preparation SQL queries.

Example 1

In this example, we will insert a new user (moderator)Ā into theĀ users table.

Query:

INSERT INTO "users" ("name", "role") VALUES ('Matt', 'moderator');

Output:

PostgreSQL - INSERT INTO statement result.
PostgreSQL - INSERT INTO statement result.

Example 2

In this example, we will insertĀ three new users into theĀ users table.

Query:

INSERT INTO "users" 
    ("name", "role") 
VALUES 
    ('Matt', 'moderator'),
    ('Peter', 'admin'),
    ('Jack', 'user');

Output:

PostgreSQL - INSERT INTO statement result.
PostgreSQL - INSERT INTO statement result.

Database preparation

create_tables.sqlĀ file:

CREATE TABLE "users" (
	"id" SERIAL PRIMARY KEY,
	"name" VARCHAR(100) NOT NULL,
	"role" VARCHAR(15) NOT NULL
);

Ā insert_data.sqlĀ file:

INSERT INTO "users"
	("name", "role")
VALUES
	('John', 'admin'),
	('Chris', 'moderator'),
	('Kate', 'user'),
	('Denis', 'moderator');
