- The question asks us to display product name and brand name from the tables PRODUCT and BRAND. These are two different tables that have a common column called BID, which stands for brand ID. This column can be used to join the two tables and fetch the relevant data.
- To display product name and brand name from the tables PRODUCT and BRAND, we need to use the SELECT statement in SQL. The SELECT statement is used to query data from one or more tables in a database.
- The syntax of the SELECT statement is:
SELECT column1, column2, ...
FROM table1, table2, ...
WHERE condition;
- The SELECT clause specifies the columns to be displayed in the result. The FROM clause specifies the tables to be queried. The WHERE clause specifies the condition to filter the rows that match the criteria.
- In this case, we want to display the PName column from the PRODUCT table and the BName column from the BRAND table. We also want to query both the PRODUCT and BRAND tables. We need to use a condition that matches the BID column from both tables, so that we can get the correct product name and brand name for each product.
- The SQL query for this question is:
SELECT PName, BName
-- Select the columns PName and BName
FROM PRODUCT, BRAND
-- Query both the PRODUCT and BRAND tables
WHERE PRODUCT.BID
= BRAND.BID; -- Use a condition that matches the BID column from both tables
- This query will display the product name and brand name for each product in the database. For example, one of the rows in the result will be:
|
PName |
BName |
|
Shampoo |
Medimix |
So, this is how we can write an SQL query to display product name and brand name from the tables PRODUCT and BRAND.
