Execute a Query

Learn how to execute SQL queries using DBCode.

First, let’s create our database table.

Open a New SQL File

To begin, open a new SQL file on the database by clicking the new file icon in the DB Code explorer.

Open SQL File

Execute a statement

To keep it simple, we will create a “departments” table first, as the “employee” table depends on it. Copy and paste the following code into the new SQL file:

-- Create the departments table
CREATE TABLE departments (
department_name VARCHAR(100) NOT NULL

To run the SQL, you can execute via these options:

  • Click the execute in the code lens at the top of the editor
  • Click the execute icon in the top right
  • Use the keyboard shortcut Ctrl/Cmd+D+E
  • Right-click and select the “Execute with DBCode” option


Inserting Data

We will insert some sample data into the newly created table. Paste the following code into the SQL File, this time, select the code to execute only this code rather than the whole file.

-- Insert data into the departments table
INSERT INTO departments (department_name) VALUES
('Human Resources'),

Run the code using one of the above-mentioned execution methods.

Viewing the Data

To verify that the data was inserted successfully, select the table from the DBCode explorer, which will open a new tab showing the records in the table.

Locate the table in the explorer and click on it to open.

View Data

Executing Multiple Statements

Let’s now execute multiple statements at once. These statements will create an “employees” table, insert some data, and perform a select query to join the employees to their departments.

Copy and paste the following code into a new SQL file, or replace the existing code in the current file:

-- Create the employees' table
CREATE TABLE employees (
position VARCHAR(50) NOT NULL,
salary NUMERIC(10, 2) NOT NULL,
hire_date DATE NOT NULL,
department_id INT,
FOREIGN KEY (department_id) REFERENCES departments(id)
-- Insert data into the employees table
INSERT INTO employees (name, position, salary, hire_date, department_id) VALUES

-- Select some data
SELECT e.name, e.position, e.salary, e.hire_date, d.department_name
FROM employees e
JOIN departments d ON e.department_id = d.id
WHERE e.salary > 70000
ORDER BY e.hire_date;

Now, execute the code. If you don’t highlight any content first, you will be prompted to execute the whole document. Select “Yes.”

The results should now be displayed in the DBCode panel at the bottom.



Congratulations, you have successfully created tables, inserted data, and retrieved it.
