INSERT Record - MySQL Queries

In MySQL, the INSERT statement is used to insert new rows into a table. In this tutorial, we'll discuss how to use the INSERT statement to insert records into a MySQL database.

Syntax

The basic syntax for the INSERT statement is as follows:

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

In this syntax, "table_name" refers to the name of the table you want to insert the records into. The columns you want to insert values into are listed in parentheses, separated by commas. The values you want to insert into those columns are listed in the VALUES clause, also separated by commas.

Example

Let's say we have a table called "employees" with the following columns: "id", "name", "age", and "salary". To add a new record to the "employees" table, we would use the following INSERT statement:

INSERT INTO employees (name, age, salary)
VALUES ('John Doe', 25, 50000);

This INSERT statement inserts a new record into the "employees" table with the name "John Doe", age "25", and salary "50000".

Output

When you execute the INSERT statement, it doesn't generate any output itself. However, you can run a SELECT query to verify that the new records have been inserted into the table:

SELECT * FROM employees;

This query will display all the records in the "employees" table, including the one we just inserted.

Explanation

In this example, we used the INSERT statement to insert a record into the "employees" table. We specified the columns we wanted to insert values into ("name", "age", and "salary") and the corresponding values we wanted to insert. The database generated a new unique ID for the "id" column automatically.

Use

The INSERT statement is used to insert new records into a MySQL table. You can use the INSERT statement to insert one or more records into a table. It's a simple and efficient way to add new data to your database.

Important Points

• When inserting records into a table, you need to specify the columns you want to insert values into.
• You should always specify the columns you want to insert values into (rather than relying on a default order) to avoid errors.
• The values you insert into the table should match the data type of the corresponding column in the table.

Summary

In this tutorial, we discussed how to use the INSERT statement to insert records into a MySQL database. We covered the syntax, example, output, explanation, use, and important points of the INSERT statement in MySQL. With this knowledge, you can now insert new records into your MySQL tables efficiently and with confidence.
