20 Consecutive Headings About SQL Server Insert Into Values

Hello Dev, are you struggling to insert data into your SQL Server database using the ‘insert into values’ statement? If so, you’ve come to the right place. In this article, we will guide you through the process of using the ‘insert into values’ statement, step-by-step. By the end of this article, you will be able to insert data into your SQL Server database with ease. Let’s get started!

Understanding the Basics of ‘Insert Into Values’

The ‘insert into values’ statement is used to insert data into a SQL Server database. It is a simple but powerful statement that can be used to add new records to a table. Before we dive into the details of how to use this statement, it’s important to understand the basic syntax.

Keyword	Description
INSERT INTO	Specifies the table name to insert data into.
VALUES	Specifies the values to be inserted into the table.

The Syntax of ‘Insert Into Values’

Now that you understand the basics of ‘insert into values’, let’s take a closer look at the syntax of this statement.

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

Explanation of the Syntax

The ‘insert into values’ statement consists of two parts: the ‘insert into’ clause and the ‘values’ clause. The ‘insert into’ clause specifies the target table and the columns into which data will be inserted. The ‘values’ clause specifies the values to be inserted into these columns.

The values in the ‘values’ clause must be in the same order as the columns in the ‘insert into’ clause. If a column is not specified in the ‘values’ clause, the database will insert a NULL value into that column.

Inserting Data into a Table Using ‘Insert Into Values’

Now that you understand the syntax of ‘insert into values’, let’s look at a practical example of how to use this statement to insert data into a table.

Step 1: Create a Table

Before we can insert data into a table, we must first create the table. Let’s create a simple ’employees’ table with four columns: ’employee_id’, ‘first_name’, ‘last_name’, and ‘salary’.

CREATE TABLE employees (employee_id INT PRIMARY KEY,first_name VARCHAR(50),last_name VARCHAR(50),salary INT);

Step 2: Insert Data into the Table

Now that we have a table, let’s insert some data into it. In this example, we’ll insert information for two employees.

INSERT INTO employees (employee_id, first_name, last_name, salary)VALUES (1, 'John', 'Doe', 50000),(2, 'Jane', 'Smith', 60000);

After running this statement, two new rows will be added to the ’employees’ table.

FAQs

What happens if I don’t specify a value for a column in the ‘values’ clause?

If you don’t specify a value for a column in the ‘values’ clause, the database will insert a NULL value into that column.

Can I insert multiple rows at once using ‘insert into values’?

Yes, you can insert multiple rows at once using ‘insert into values’. Simply separate each set of values with a comma, as shown in the example above.

What is the maximum number of rows I can insert at once using ‘insert into values’?

The maximum number of rows you can insert at once using ‘insert into values’ depends on the size of your database and the resources available on your server. However, it is generally recommended to insert no more than 1000 rows at a time to avoid performance issues.

Can I use variables in the ‘values’ clause?

Yes, you can use variables in the ‘values’ clause. Simply replace the values with variables, like this:

DECLARE @id INT = 3;DECLARE @first_name VARCHAR(50) = 'Bob';DECLARE @last_name VARCHAR(50) = 'Jones';DECLARE @salary INT = 70000;INSERT INTO employees (employee_id, first_name, last_name, salary)VALUES (@id, @first_name, @last_name, @salary);

Can I insert data into a table without specifying the column names?

Yes, you can insert data into a table without specifying the column names. However, it is generally recommended to specify the column names to avoid errors and improve readability.
