CAML Query to search comma separated values similar to SQL query

Question

Instead of below query, is possible to write dynamic CAML query for below CAML query. because below query will not work for dynamic data:

<Where>
    <Or>
        <Or>
            <Eq>
                <FieldRef Name='VehicleLine' />
                <Value Type='Text'>Test1</Value>
            </Eq>
        </Or>       
    <Or>
            <Eq>
                <FieldRef Name='VehicleLine' />
                <Value Type='Text'>Test2</Value>
            </Eq>
        </Or>       
    <Or>
            <Eq>
                <FieldRef Name='VehicleLine' />
                <Value Type='Text'>Test3</Value>
            </Eq>
        </Or>       
    </Or>
</Where>

I cannot find a close example for what I am trying to achieve, which is to check multiple fields for multiple values. Yes, I have looked on SO already for my answer, including this one: Need help on building dynamic CAML Query.

With that said, if it is possible, how can the following SQL-like query be written in CAML?

DECLARE @VehicleLines VARCHAR(50)='Test1','Test2','Test3'; --it can anything (based on user selection)

SELECT * FROM Master WHERE VehicleLine IN (@VehicleLines)

I want to use CAML query in javascript to fetch data from list.

Because it's a CSV, equals will never work. Consider using <Contains>:

<Where>
  <Or>
    <Or>
      <Contains>
        <FieldRef Name='VehicleLine' />
        <Value Type='Text'>Test1</Value>
      </Contains>
      <Contains>
        <FieldRef Name='VehicleLine' />
        <Value Type='Text'>Test2</Value>
      </Contains>
    </Or>
    <Contains>
      <FieldRef Name='VehicleLine' />
      <Value Type='Text'>Test3</Value>
    </Contains>
  </Or>
</Where>

Regarding dynamic building of Caml, there are many libraries that will do that for you. I've always used roboCAML for such requirements.
