To insert multiple records into a table using a single INSERT statement in SQL, you can use the following syntax:
INSERT INTO employees (column1, column2, ...)
VALUES
(value1_1, value1_2, ...),
(value2_1, value2_2, ...),
...
(valueN_1, valueN_2, ...);
Here's an example of inserting multiple records into the "employees" table:
-- Insert multiple records into the "employees" table
INSERT INTO employees (employee_id, first_name, last_name, department, salary)
VALUES
(5, 'Chanchal', 'Wankhade', 'IT', 58000.00),
(6, 'Sarah', 'Wilson', 'Engineering', 62000.00),
(7, 'Jessica', 'Lee', 'Marketing', 54000.00);
In this example:
- We specify the columns (employee_id, first_name, last_name, department, salary) after the INSERT INTO clause.
- We provide multiple sets of values within the VALUES clause, separated by commas.
- Each set of values corresponds to a single record to be inserted into the table.
You can adjust the column names and values based on your specific table structure and data. Let me know if you need further assistance!
