Insert Data - SQL Server Database

Inserting data into a SQL Server database is a fundamental operation in database management. In this page, we will cover how to insert data into a SQL Server database using the SQL INSERT statement.

Syntax

The basic syntax for inserting data into a SQL Server database using the INSERT statement is as follows:

INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

Here, table_name is the name of the table where you want to insert data, column1, column2, column3, ... refers to the column names in the table, and value1, value2, value3, ... refers to the corresponding values that you want to insert into those columns.

Example

Let's assume we have a table called employees with columns employee_id, first_name, last_name, job_title, and salary. Here's an example of inserting a new employee record into the employees table:

INSERT INTO employees (employee_id, first_name, last_name, job_title, salary)
VALUES (101, 'John', 'Doe', 'Software Developer', 75000);

Output

If the INSERT statement is executed successfully, the database will return a message stating the numbers of rows affected. This message indicates that you have successfully inserted data into the table.

Explanation

The INSERT statement is a SQL Server query that adds one or more new rows to a table. The VALUES clause following the INSERT INTO statement specifies the data to be inserted into the database. The data must be provided in the same order as the columns specified in the INSERT INTO statement.

Use

Inserting data is useful when you need to add new rows to a table in a SQL Server database. This operation is commonly used in applications that need to store user data or other information.

Important Points

  • All names (table name, column names, etc.) must be spelled correctly and case-sensitive.
  • The data type of the values being inserted must match the data type of the columns in the table.
  • The order of the columns in the INSERT INTO statement must match the order of the values in the VALUES clause.

Summary

In this page, we covered the basic syntax and example of inserting data into a SQL Server database using the INSERT statement. We also provided an explanation of how the INSERT statement works and when to use it. Finally, we discussed the important points to keep in mind when inserting data into a SQL Server database.
