I am trying to get fetch a blob column from a MS-SQL(7) table. and SQL
select terminates with and error:
SQL ERR on: Select viewcontent from NewProfile where ID='Prof2' and
CUSTID='sandy'

SQL-Err:[911] [4] [0] "Could not allocate enough memory (-1 bytes) for
column 1.

'viewcontent' is a Blob (Image) field in MS-SQL (ver 7.0)
