![]() postgres_project=# SELECT * FROM comments ĬommentId | commentBody | lastModifiedAt | createdAt | employeeId If we run the SELECT query we will get the entry we made. ("employeeId", "commentBody", "lastModifiedAt", "createdAt") In the following example we are inserting a comment from the e03 employeeId account. So, when we insert a row in the comments table we also have to provide a value for the employeeId column and this value must exists in the employee table. The comments table has a foreign key employeeId. Insert into comments table with foreign key If we now run the SELECT query we will get three rows in the employee table. ("employeeId", "firstName", "lastName", email, score, birthday, "lastModifiedAt", "createdAt") Lets insert two more employee details and this time let us insert values for all the columns. We will learn about SELECT query in the later part of this tutorial series. postgres_project=# SELECT * FROM employee ĮmployeeId | firstName | lastName | score | lastModifiedAt | createdAt | birthday | email ![]() If we want to check the inserted row then we can use the SELECT query. Note! value for the score column is skipped so, it will get the default value set for it and i.e., 0. Object identifiers (OIDs) are used internally by PostgreSQL as primary keys for various system tables.įor more details checkout this INSERT documentation of Postgres. The count is the number of rows inserted or updated. On successful completion INSERT returns command tag of the form INSERT oid count. ("employeeId", "firstName", "lastName", email, birthday, "lastModifiedAt", "createdAt") We are inserting values for the given columns: employeeId, firstName, lastName, score, birthday, email, lastModifiedAt and createdAt. In this section we are going to insert data into the employeetable. To insert multiple rows in a table we use the following syntax. Where, table_name is the name of the table in which we are going to insert the values value1, value2. We use the following to insert data into specific columns. Where, table_name is the name of the table in which we are going to insert the following value1, value2. ![]() INSERT INTO table_name VALUES ('value1', 'value2'. To insert data into the table we use the following syntax. Insert into comments table with foreign key.We are going to use the following tables that we created in the CREATE table tutorial. In this tutorial we will learn to insert data into tables in Postgres. ![]()
