如何选择两个不同的列从一个表中获取一些id的两次？

I have a table like this :

        id   firstname  lastname    cilinic1    cilinic2  ...   insurance1   insurance2
         1   rose       golabi      bla bla     bla bla          firaga        atena

        *2   ...         ...          ...        ...             filoli*       filoli*

         3   ...         ...          ...        ...              tomis         atena
         .
         .
         .

When user tries to search for a specific insurance like (atena) , I make a query like this:

        SELECT * FROM doctors WHERE insurance1 LIKE ($userinput) ..

But this query will search just in insurance1

The problem is , some doctors have 2 different clinics , and in each clinic maybe accept the same insurance (Like the row number 2 from this table , which I emphesized with * ) .

So , I have to search in both insurance1 ANd insurance2 simultaneously , and if a doctor accepts same insurance in 2 clinic , I want to show that doctor twice in the search result

what should I do ?

(NOTE: I have to select * , because there are 12 columns in my table and I have to show everything in the search result(firstname,lastname,age,gender,city,....))

Is There a way to say this sentence to mysql :

      if you selected from **insurance1** then (function...)
      if you selected from **insurance2** then (function...)

????

You can use UNION to combine two separate queries:

SELECT * FROM doctors WHERE insurance1 LIKE ($userinput) ..
UNION ALL
SELECT * FROM doctors WHERE insurance2 LIKE ($userinput) ..
