Sample Solution:
-- This SQL query retrieves data from the Sales.SalesPerson table and applies various casting operations on the SalesYTD column.
-- Selecting columns: BusinessEntityID, SalesYTD, MoneyDisplayStyle1, CurrentDate, and DateDisplayStyle3.
SELECT BusinessEntityID,
SalesYTD,
CAST(SalesYTD AS VARCHAR) AS MoneyDisplayStyle1,
NOW() AS CurrentDate,
CAST(NOW() AS VARCHAR) AS DateDisplayStyle3
-- From the Sales.SalesPerson table.
FROM Sales.SalesPerson
-- Filtering the results based on the SalesYTD column.
WHERE CAST(SalesYTD AS VARCHAR(20)) LIKE '1%';
Explanation:
- The query retrieves data from the SalesPerson table in the Sales schema.
- It selects five columns: BusinessEntityID, SalesYTD, MoneyDisplayStyle1, CurrentDate, and DateDisplayStyle3.
- The CAST function is used to convert the SalesYTD column to a VARCHAR data type and assign it an alias MoneyDisplayStyle1.
- The NOW() function is used to retrieve the current date and time, and it is aliased as CurrentDate.
- Another CAST function is applied to the current date to convert it to a VARCHAR data type, and it is assigned an alias DateDisplayStyle3.
- The WHERE clause filters the results based on the SalesYTD column:
- Only rows where the SalesYTD value, when cast to VARCHAR with a length of 20 characters, starts with '1' will be included in the result set.
