[DB-SIG] Insert for Oracledb

[Victoria White]

Cary,
      Yes, thank you for your response.  That indeed does work, however I put that into the category of  'hardcoding the values into the sql string' - since you basically explicitly
convert to ASCII with str() and insert into the sql string.  I had hoped that I could use
      execute(sqlstring, [params...])  as documented in the DBI document  with params presented as one (or more) parameters giving basically a List of Tuples (or arrays of values)  to be
"bound" to the input column names given, in some Oracle-specific/binding magic format, in the sql string.  However, I find that  a) only one param is permitted with the oracledb
implementation     and
b) I cannot find the secret way to "bind" the List of Tuples into the sql command - not even for a single record insert, although I really want it to work for a whole list of tuples.
      It is probably extremely simple and just that I don't understand the notation
involved in specifying the sqlstring and its column names to be bound.
       However, I do appreciate your response and am interested to find another living soul using this package.
