    Try something like this,

    SELECT a.ID AS ServiceID,
           a.Service_Type_Text,
           b.ID AS table2ID,
           b.Service_Type
    FROM   table1 a
           INNER JOIN table2 b
               ON a.ID = b.Service_Type

    Set your query so that it returns all data from the second table but only the required field (column) from the first.
    Something like this:

    SELECT TAB1.SERVICE_TYPE_TEXT, TAB2.*
    FROM TAB1
    INNER JOIN
    TAB2
    ON TAB1.ID = TAB2.SERVICE_TYPE

    TRY

     SELECT a.ID AS ServiceID,
           a.Service_Type_Text,
           b.ID AS table2ID,
           b.Service_Type
    FROM   table1 a
           INNER JOIN table2 b
               ON a.ID = b.Service_Type AND b.ID='YOUR_ID';
