title: Inconsistent datatype: lob type comparision in sap hana
body: <p>I wanted to see the xml files of information views that are stored in cdata column of _SYS_REPO.ACTIVE_OBJECT in SAP HANA.
  But unfortunately, when i'm trying to filter cdata empty values, its throwing the below error:
  <strong>"Inconsistent datatype: lob type comparison.</strong></p>
  
  <p>Query used to filter and view CDATA column are:</p>
  
  <p><strong>SELECT top 10  CDATA FROM _SYS_REPO.ACTIVE_OBJECT where cdata is not null"
  SELECT top 10  CDATA FROM _SYS_REPO.ACTIVE_OBJECT where cdata !=""</strong></p>
