Inserting Data into SQL Server Tables - A Beginner's Guide

Once you've created tables in SQL Server, the next step is populating them with data. In this beginner's guide, we'll explore how to insert data into SQL Server tables, covering basic and common scenarios for data insertion.

Basic Syntax for Inserting Data

The basic syntax for inserting data into a table is using the INSERT INTO statement, followed by the table name and the values to be inserted:

-- Insert data into a table
INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...);
    

Replace "table_name" with the name of the table you want to insert data into, and provide values for the columns specified in the parentheses.

Example 1: Inserting a Single Row

To insert a single row into a table, you can use the following SQL code:

-- Insert a single row into the "employees" table
INSERT INTO employees (first_name, last_name, salary)
VALUES ('John', 'Doe', 50000);
    

Example 2: Inserting Multiple Rows

If you want to insert multiple rows at once, you can use a single INSERT INTO statement with multiple VALUES clauses:

-- Insert multiple rows into the "employees" table
INSERT INTO employees (first_name, last_name, salary)
VALUES ('Alice', 'Smith', 60000),
       ('Bob', 'Johnson', 55000),
       ('Eve', 'Williams', 52000);
