Write a query to display the 'rate' of slab whose from_unit is 2001 and to_unit is 4500.Note:
Solution
Assuming you are using SQL, the query would look something like this:
SELECT rate
FROM slab
WHERE from_unit = 2001 AND to_unit = 4500;
Here's the step by step breakdown:
-
SELECT rate: This part of the query is telling the database that you want to retrieve the 'rate' column from a certain table. -
FROM slab: This part of the query specifies the table you want to retrieve data from, which in this case is the 'slab' table. -
WHERE from_unit = 2001 AND to_unit = 4500;: This is the condition for the data to be retrieved. It's telling the database to only retrieve the rows where 'from_unit' is 2001 and 'to_unit' is 4500.
