Step 1: Insert Date Value into a Table Using INSERT Query In this example, we will insert a date value to a particular table: To do this, we need to follow the Year-month-day format, i.e., “YYYY-MM-DD”.Įxample: How to Insert a Date to a Specific Table? Postgres allows us to insert a date into a column using the DATE type. How to Insert a Date Value to a Column in PostgreSQL? The output shows that the RETURNING clause returns the last entered id. Let’s run the RETURNING clause with the collaboration of the INSERT INTO statement to get the last inserted id: INSERT INTO team_info (team_id, team_name, team_ranking) The above-given query will insert the values into the specified columns and will return the last inserted id.Įxample: How to use the RETURNING clause in PostgreSQL? Here is the basic syntax of RETURNING clause of the INSERT statement in Postgres: INSERT INTO tab_name (col_1, col_2, col_3.col_N) Use the RETURNING clause with the “INSERT INTO” command to get the last entered/inserted id from the selected table. What does the RETURNING clause do in PostgreSQL? The output shows that the data has been inserted into the selected table successfully. Use the SELECT command to verify whether the data has been added to the selected table or not: Select * from team_info Step 2: Verify the Inserted Data Using Select Command In the above snippet we utilized the INSERT INTO query to insert four rows into the team_info table. Run the INSERT INTO statement to insert some data into the “team_info” table: INSERT INTO team_info (team_id, team_name, team_ranking) In this example, we will use the comma-separated syntax to insert multiple rows in the “team_info” table using the “INSERT” query: The output authenticates that the data has been inserted into the selected table.Įxample # 2: How to Insert Several Rows to a Table in PostgreSQL? On successful execution of the select command, you will get the following output: The “SELECT *” command will fetch all the column’s data. Step 4: Verify the Inserted Data Using Select CommandĮxecute the SELECT query to check whether the data has been inserted into the selected table or not: SELECT * from team_info The output shows that one row has been inserted successfully into the team_info table. Let’s execute the INSERT INTO command to insert some data into the “team_info” table: INSERT INTO team_info (team_id, team_name, team_ranking) Type the “\d” command followed by the table name, i.e., “team_info”, and hit the enter button to illustrate the table details: \d team_info Step 2: Describe the Selected Table Using \d Command Let’s say we need to insert data into the “team_info” table. There must be the same order of the column names and values.Įxample # 1: How to Insert a Single Row to a Table in PostgreSQL?įollow the below-given step-by-step guidelines to insert data into a specific table in Postgres:įirstly, select a table where you want to insert the data. VALUES is a clause used between the column names and an ordered list of comma-separated values.Īll in all, the INSERT INTO command takes a list of column names and values in a specific order and inserts them into the selected table. tab_name is the name of the targeted table, col_1, col_2, col_3. Firstly, specifies the INSERT INTO command to insert a specific record into the targeted table. The above snippet utilizes the following standards: Use the Keyword “DEFAULT VALUES” to insert default values to the columns.įollowing will be the basic syntax of the INSERT INTO command in PostgreSQL: INSERT INTO tab_name (col_1, col_2, col_3.col_N) Postgres will utilize the column’s default value if someone skips the optional columns. In PostgreSQL, omitting the mandatory columns in the INSERT command will throw an error. Use the “YYYY-MM-DD” format to insert a date into a table. The character data must be enclosed in single quotes (‘) such as 'INSERT QUERY'. Let’s consider the below-listed points for a profound understanding of the INSERT query: So, let’s learn how to use INSERT Query in PostgreSQL with the help of some practical examples.Īs we have discussed earlier, the INSERT command/statement is used to insert new records in any specific table. Using the INSERT query, an individual or several records can be added to the selected table. PostgreSQL offers a convenient statement named “INSERT” that is used to insert/add new records in a table.
