title: And + Or in one Select-Statement
body: <p>In my select statement I chain different conditions with AND. Now I need for one condition an OR.
  How can I add this for just this one Attribute without affecting the other AND-statements before?
  That's my coding:</p>
  
  <p><code>SELECT pernr reinr pdatv pdatb pdvrs abrec FROM PTRV_PERIO
      INTO CORRESPONDING FIELDS OF TABLE lt_ptrv_perio
      WHERE pdatv GE pa_begda
      AND   pdatb LE pa_endda
      AND   abrec EQ '2'.</code></p>
  
  <p>For the last condition <code>abrec EQ '2'</code> I need an OR as well, like <code>abrec EQ '2' OR '3'</code>.
  How can I add this the best way without affecting the other ANDs?</p>
  
  <p>Thanks for your hints!</p>
