In this quick little post, I would like to document how to travers a SQL SELECT statement to return back a BIT/BOOLEAN. Suppose, you want to return true of false, based on a condition and your application can simply read this BIT/BOOLEAN and show appropriate view/response to end user.
SELECT [Account].Balance, CAST(CASE WHEN [Account].Balance - @Value > 0 THEN 1 ELSE 0 END AS Bit) AS MoneyAvailable FROM [dbo].[UserAccounts] [Account] WHERE [Account].[UserId] = 13
The above statement will return a nice little one column ‘MoneyAvailable’ with a 1 or a 0 to denote if that account has available balance or not. Good stuff.
