In my case,

I was storing the sql query in my database as text. I am showing you one record which is present in my database

Query.all

:id  => 1, :sql => "select * from user where id = #{params[:id]}"

str = Query.first

Now 'str' has value "select * from user where id = #{params[:id]}"

Here, I want to parsed the string like If my params[:id] is 1 then

"select * from user where id = 1"

I used eval(str). Is this correct?
