you can even store query in variable then use exec to run it

declare @sqlvarchar(100)
set @sql='select * from tablename'
exec(@sql)

What HuyBD is correct, but you can not select directly from the variable, like this:

SELECT * FROM @tablename

You'd have to use dynamic SQL, like this:

declare @SQL varchar(1000)
set @SQL = 'SELECT * FROM ' + @tablename
exec(@SQL)

This doesn't work:

declare @TableName varchar(20)
set @TableName = 'dbo.SomeTable'

create table dbo.SomeTable
(id int,
name varchar(20)
)

insert into dbo.SomeTable(id,name)
values(0, 'John')

select * from @TableName
0
