Changing a SQL column title via query

Question

I have the following query:

SELECT product_description.name, product.quantity,product.price,product_option_value_description.name,product_option_value.quanti         


        

Answer 1

Just write product_option_value_description.name AS Name to create the alias "Name" for this column.

Answer 2

You can use any alias name using the 'AS' keyword. eg. select student_id AS id from student_info

Answer 3

Use as

For example:

SELECT product_description.name as 'ProdName', product.quantity,product.price,product_option_value_description.name as 'ProdDesc',product_option_value.quantity FROM product

Answer 4

Use an alias like so:

product_option_value_description.name AS `Option`

If you want to change the column's name, not only for this query but in general use ALTER TABLE

ALTER TABLE product_option_value_description CHANGE name newname DATATYPE;
