Hi, I have written a C++ ODBC wrapper that right now runs on
Oracle,Access,SQL Server, Sybase.
I am right now investigating PostgreSQL which we want to use instead of
SQL Server.
PostgreSQL Version: 7.33 (Cygwin/Windows XP) using ipc-daemon
ODBC Version: 7.03.01.10
OS: Windows XP Pro, SP1
Synopsis:
I basically open a connection to a db, create a statement,use a dynamic
cursor
via SQLSetConnectAttr (SQL_ATTR_CURSOR_TYPE, SQL_CURSOR_DYNAMIC),
execute the statement
, bind some fields and want to fetch data using SQLFetchScroll
(m_hstmt, SQL_FETCH_ABSOLUTE,
lPosition).
The SQLFetchScroll statement fails with the following message:
'HY106 - the fetch type for PGAPI_ExtendedFetch isn't allowed for
ForwardOnly cursor.'
Which of course irritates me because I explicitely use
SQL_CURSOR_DYNAMIC.
I attached the standard windows SQL.log with some mixins of the code I
called. It is not the complete
log and it is not the PostgreSQL-Driver specific log, which is far too
verbose for me.
I have enabled the Dynamic cursor checkbox in the driver.
Any suggestions?
Another question: are positionable updates and deletes (which means
SQLSetPos) possible with
PostgreSQL at present (as mentioned in
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/odbc/ht
m/odch12pr_2.asp) ?
Thanks for your help
