To insert data into a table in Microsoft SQL Server (MSSQL), you can use the INSERT INTO statement. Here's the basic syntax:
INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...);
- table_name: The name of the table where you want to insert data.
- column1, column2, ...: The columns into which you want to insert data.
- value1, value2, ...: The values you want to insert into the corresponding columns.
Let's look steps to insert data:-
Let's go through the process of creating a table in MSSQL, inserting data into it, and then displaying the output.
Step 1: Create Table Statement
Let's create a simple table named employees with columns for id, name, and age.
CREATE TABLE employees (
id INT PRIMARY KEY,
name VARCHAR(50),
age INT
);
Step 2: Insert Data
Now, let's insert some data into the employees table.
INSERT INTO employees (id, name, age)
VALUES (1, 'John', 30),
(2, 'Emily', 28),
(3, 'Michael', 35),
(4, 'Sophia', 32);
Step 3: Display Output
Let's select all rows from the employees table to see the inserted data.
SELECT * FROM employees;
Output:
| id | name | age |
|----|----------|-----|
| 1 | John | 30 |
| 2 | Emily | 28 |
| 3 | Michael | 35 |
| 4 | Sophia | 32 |
This output shows the data that we inserted into the employees table. Each row represents an employee with their respective ID, name, and age.
Here are five frequently asked questions (FAQs) about inserting data in Microsoft SQL Server (MSSQL):-
1. What is the purpose of the INSERT INTO statement in MSSQL?
- The INSERT INTO statement is used to add new rows of data into a table in a MSSQL database.
2. How do I insert data into multiple columns using INSERT INTO in MSSQL?
- To insert data into multiple columns, specify the column names in parentheses after the table name, followed by the VALUES keyword and the corresponding values in parentheses.
3. Can I insert data into specific columns only in MSSQL?
- Yes, you can specify the columns into which you want to insert data in the INSERT INTO statement. Simply provide the column names in parentheses after the table name, followed by the VALUES keyword and the corresponding values in parentheses, matching the order of the columns.
4. Is it necessary to specify values for all columns when inserting data in MSSQL?
- No, it's not necessary to specify values for all columns. You can insert data only into the columns that require values, leaving the other columns NULL if they allow NULL values or have default values.
5. Can I insert data into a table using a query result in MSSQL?
- Yes, you can use a SELECT statement within the INSERT INTO statement to insert data into a table from the result of a query. This is useful for copying data from one table to another or for inserting calculated values.
