Summary: Rollback in manual transaction

Initial Comment:
Postgres 8.1 either Windows or linux
psqlODBC 08.01.0200
..Net Framework 1.1 in particular Visual Basic

In Notes: psqlODBC 08.01.0106 I read:
....
3) doesn't call rollback in autocommit off or in manual transaction
....

But Executing a statement in a transaction which gives an error causes an implicit rollback of the transaction and the close of the connection.
Sample code:

Dim cnt As New Odbc.OdbcConnection"Driver={PostgreSQL Unicode}; Server=****; Database=test_ado; Uid=postgres; Password=****; BoolsAsChar=0; Parse=0; UniqueIndex=1; TextAsLongVarchar=1; LowerCaseIdentifier=1")
Dim tra As Odbc.OdbcTransaction
Dim sSql As String

Try
cnt.Open()
tra = cnt.BeginTransaction()
'Setting Primary key to Null cause an error
sSql = "UPDATE test_ado SET cod=Null WHERE cod ='00004'"
Dim cmd As New Odbc.OdbcCommand(sSql, cnt)
cmd.CommandText = sSql
cmd.Transaction = tra
cmd.ExecuteNonQuery()

Catch ex As Exception
MsgBox(ex.Message)
MsgBox(cnt.State.ToString)
End Try

Unfortunateky I don't know when the official libpq version will implement the functionalities which
the REL_07_03_ENHANCED already has.

Message:
REL-07_03_ENHANCED works correctly. I have not properly
understood whether the functions of this version will be
present in the official release or if they belong to two
different projects

choose an index scan if your joining column's datatypes do not
match
