INSERT INTO SELECT MySQL Example

Suppose we have the following vendors table with the following structure.

CREATE TABLE vendors(
     id INT AUTO_INCREMENT,
     name VARCHAR(50) NOT NULL,
     phone VARCHAR(50),
     addressLine1 VARCHAR(50),
     addressLine2 VARCHAR(50),
     city VARCHAR(50),
     state VARCHAR(50),
     postalCode VARCHAR(50),
     country VARCHAR(50),
     customer_id INT
     PRIMARY KEY (id)
 );

To create a vendor table, you just need to execute the MySQL query.

Now, you need to include these customers in the Vendor table from the Customer table. The following MySQL statement copies “Vendors” to “Customers”.

INSERT INTO vendors (
     name, 
     phone, 
     addressLine1,
     addressLine2,
     city,
     state,
     postalCode,
     country,
     customer_id
 )
 SELECT 
     name,
     phone,
     addressLine1,
     addressLine2,
     city,
     state ,
     postalCode,
     country,
     customer_id
 FROM 
     customers;

The following MySQL statement copies only the UK vendors into “Customers”.

INSERT INTO vendors (
     name, 
     phone, 
     addressLine1,
     addressLine2,
     city,
     state,
     postalCode,
     country,
     customer_id
 )
 SELECT 
     name,
     phone,
     addressLine1,
     addressLine2,
     city,
     state ,
     postalCode,
     country,
     customer_id
 FROM 
     customers
 WHERE 
     country = 'UK';

After inserting data using the MySQL INSERT INTO SELECT statement query, the following query returns data from the vendors table : –

SELECT * FROM vendors;
