To Search Data in Multiple Columns using 'IN' Clause

Using the Code
Create a table with some dummy records to  show the demonstration:
Hide   Copy Code
create table tbl_test
(id int identity(1,1),
column1 nvarchar(50),
coulmn2 nvarchar(50),
coulmn3 nvarchar(50))-- Create a table 
insert into tbl_Test (column1,coulmn2,coulmn3) values
('Griff','Serjey','Maciej'),
('King','Fisher','Ajay'),
('Paul','Griff','Serjey'),
('King','Fisher','Griff')--Inserting some Dummy Records
Now, I'm going to search the value where the data is 'Griff'. In the above table, there are 3 rows that contain 'Griff'.
Hide   Copy Code
select *from tbl_test where 'Griff' IN (column1,coulmn2,coulmn3)
By executing the above query, we will get the resultset like below:
Hide   Copy Code
id   column1    coulmn2    coulmn3
1    Griff      Serjey    Maciej
3    Paul       Griff     Serjey
4    King       Richard   Griff
The query will check all the mentioned columns where the input data is available by using the simple 'IN' clause.
