Version: 3.0.3 32Bit
ODB driver: 2.0.5 32 Bit
I'm migrating a C++ App from MS-Access to Firebird 3.0.
With MS-Access I used the identity column as primary key for table joining.
Firebird gives the possibility to create a similar table with:
CREATE TABLE TestTable (ID INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY
KEY, Name VARCHAR(50));
The whole app is written with ADO, so I'd like to use the firebird ODBC. But
here occurs the following problem:
reading the just generated identity throws an exception, I didn't have with
MS-Access.
ADODB::_RecordsetPtr prs = NULL;
CREATEINSTANCE(prs, ADODB::Recordset);
prs->CursorLocation = ADODB::adUseClient;
prs->Properties->Item["Update Resync"]->Value =
(long)ADODB::adResyncAll;
prs->Open(_bstr_t("SELECT * FROM TestTable WHERE 1=0"),
(IDispatch *)m_pConnection, ADODB::adOpenKeyset, ADODB::adLockOptimistic,
ADODB::adCmdText);
prs->AddNew();
prs->Fields->Item["Name"]->Value = "Some Text";
prs->Update();
long id = (long)prs->Fields->Item["ID"]->Value;
// throws an DB_E_DELETEDROW
prs->Close();
prs = NULL;
I need to know the generated ID for further actions in other subtables.
Has somebody the same issue and even better - a solution for this?
