I have select in the label model with fields from ORACLE table of BLOB-types. When I try to make preview I will see ODBC error like

"[Microsoft][Driver's dispatcher] Invalid descriptor index

Error S1002: Invalid column number"

This is my sql-script:

SELECT replace(regexp_substr(s.description,'\|[^\|]*',1,7),'|',null) AS sku_name,
       replace(regexp_substr(s.description,'\|[^\|]*',1,8),'|',null) AS sku_id,
       replace(regexp_substr(s.description,'\|[^\|]*',1,3),'|',null) AS colour,
replace(regexp_substr(s.description,'\|[^\|]*',1,5),'|',null) AS logo,
replace(regexp_substr(s.description,'\|[^\|]*',1,13),'|',null) AS prom1,
       ci.base_units,
       cp.num,
       cp.blob2,
       cp.blob5,
       replace(regexp_substr(s.description,'\|[^\|]*',1,10),'|',null) AS ean14,
       ('022'||substr(ld.name,4,7)) AS batch_no,

  FROM loads ld, sku s, code_info ci, code_info ci2, cca_tetr cp,
       (SELECT to_date('201'||substr(ld2.name,4,1)||'-'||substr(ld2.name,5,3), 'YYYY-DDD') AS lot_date FROM loads ld2 WHERE ld2.id='?SOLVO_IDX_1') t
 WHERE s.id=ld.sku_id
   AND ci.id=(SELECT max(ci3.id) FROM code_info ci3 WHERE ci3.sku_id=ld.sku_id AND ci3.ctn_type=2)

   AND ci2.id=(SELECT max(ci4.id) FROM code_info ci4 WHERE ci4.sku_id=ld.sku_id AND ci4.ctn_type=3)
   AND ld.id='?SOLVO_IDX_1'
and (replace(regexp_substr(s.description,'\|[^\|]*',1,11),'|',null))=cp.num

When I comment strings "cp.blob2, cp.blob5", all is good - no errors. May be Bartender doesn't support preview blob-type fields? Can somebody help me with this situation?
