I have a table of bus route. this table has fields like bus no. , route code , starting point , end point, and upto 10 halts from halt1 , halt2...halt10 . i have filled data in this table. now i want to select all rows having two values,for example jaipur and vasai. in my table, there are two rows that have jaipur and vasai. In one row, jaipur is in column halt2 and vasai in halt9. Similarly another row has jaipur in halt4 column and vasai in halt10 column.

Answer 1

use CONTAINS
SELECT *
WHERE CONTAINS((startingpoint,endpoint,halt1,halt2,halt3,halt4,halt5,halt6,halt7,halt8,halt9,halt10), 'jaipur')
AND CONTAINS((startingpoint,endpoint,halt1,halt2,halt3,halt4,halt5,halt6,halt7,halt8,halt9,halt10), 'vasai');

Answer 2

SELECT * FROM bus_rout WHERE (halt1='aaa' OR halt2='aaa' OR .... halt10='aaa') AND (halt1='bbb' OR halt2='bbb' OR ....... halt10='bbb')
The where clause could be generated by code.

Answer 3

Based on your input, it seems to be a necessity for you to have Normalized table structure.
CREATE TABLE [dbo].[MyRoutes](
[id] [int] IDENTITY(1,1) NOT NULL,
[Route_No] [nvarchar](50) NULL,
[Route_Code] [nvarchar](50) NULL,
[Color] [nvarchar](50) NULL,
[Start_Point] [nvarchar](200) NULL,
[End_Point] [nvarchar](200) NULL,
[HaltNum] INT,
[Halt] [nvarchar](50) NULL
)
Then a query to solve the routes problem can be written as below:
SELECT a.Route_No, a.Route_Code, a.Color, a.Start_Point, a.End_Point,
a.HaltNum StartNum, b.HaltNum StopNum
FROM MyRoutes a
INNER JOIN MyRoutes b
ON a.id = b.id
WHERE a.Halt = 'jaipur' AND b.Halt = 'vasai'
AND a.HaltNum < b.HaltNum
Even better design of the table structure would be to have a separate master table for all Stops where you can maintain only StopId and StopName. In the MyRoutes table then you can have HaltId as foreign key referencing StopId column of the all stops master table. The above query would then need to inner join with this table twice to have conditions on StopName
