I want to write a query to get the customer name and product name order by first name.
I have two tables in my MySQL database, let's call them customer details table
and product detail table
. Each table has several columns, but I only want to join them based on specific columns. For example, let's say I want to join customer details table.first_name
with product detail table.product_name
.
Could someone please provide me with the correct MySQL query syntax to achieve this? Also, if there are any performance considerations or best practices I should be aware of when joining tables in this manner, I would appreciate any insights.
As your image, it has customer_id
in both tables which we can use for joining.
Or you can join with any column name with following syntax.
But Joining using "strings" might be caused to following issues
To avoid these issues, it's generally recommended to join using "int"
SELECT
`c`.`first_name`,
`p`.`product_name`
FROM `customer_details` AS `c`
JOIN `product_details` AS `p` ON `c`.`customer_id` = `p`.`customer_id`
ORDER BY
`c`.`first_name`;
