Do you store floor detail in other table?

Convert Room No to string and take substring of it
eg:- string FloorNo=stringRoomNo.SubString(0,1);

I think you should cop up all this on the design size.. you can create a dropdown list with Floor numbers and on its selected index changed you can populate other dropdown list by room numbers. and so on....

Solution 1

Create a table named TBL_ROOM like this

SQL

TBL_ROOM
(
  ROOM_ID INT,
  ROOM_NO INT,
  FLOOR_NO INT,
  FLOOR_DISPLAY_NAME VARCHAR(20)
);

Store your room information in this table like this

1 11 1 1stFloor
2 12 1 1stFloor

now simply get a join to this table on ROOM_NO, your porblem shoul get resolved.

Thanks

Solution 2

I see the dependence between number of room and floor level ;)

SQL

SELECT Course, roomno, Dateofcrs, CASE
	WHEN roomno <20 THEN 'firstfloor'
	WHEN roomno >=20 THEN 'secondfloor'
	ELSE 'where am i?'
	END AS [Floor]
FROM TableName
