DB2 CONNECT / DB2CONNCT / B10 - DB2

Business Impact Level: This is POC and we are migrating .NET
application from Netezza to IIAS
Business Impact Description: Application migration is failing
for BOOL datatypE

Environment: IIAS version 1.0.8

Mismatch of Boolean data type :
MS data type is BOOL where as DB2 LUW type is has SQL_Boolean
which is causing the problem. They are trying to connect via
ODBC and when accessing boolean datatype, they are getting error
unknown SQL type -16

============
Bool types in DB2 are known as SQL_BOOLEAN(2 bytes length) and
in microsoft ODBC specification, matching data type for BOOL is
SQL_BIT(1 byte length).
Since application is fetching describe information for bool type
and DB2 server is returning SQL_BOOLEAN(2 bytes length), this
does not map to SQL_BIT. as per ODBC standard, SQL_BOOLEAN is 16
and SQL_BIT is -7.
But we are DB2 compliant as DB2 expects SQL_BOOLEAN for Boolean
type.

Either way, we need a mapping. We cannot go back and change
server interpretation, however, we can provide patch in client
to have correct mapping according to ODBC standard.
