PostgreSQL version: 8.4.1
Operating system: Ubuntu 9.10 accessed by Vista Home basic
Description: fire IDispatch Error #3015 when run PutCollect() in ADO
Details:
I have to convert our group's code from MySQL to pgSQL , this project was
built and tested first under MS-Access 2003, then to MY-SQL 5.0, 5.1, and
now they want me to convert it to pgSQL because some large table need to be
divided into sub tables, pg is a good chioce.
the pg Server is inited in Ubuntu 9.10, testing tables has been created very
simple(I'm a beginner in pgSQL),
sindex varchar (24)(PK)
strname varchar (24)
sage integer
spicture bytea
coded as UTF-8 (to hold asian chars)
the client program runs on MS Vista Home, built by MSVC2008. because this
project is first for MS Access 2003, All DB opers are coded as ADo-Record
set.
I use pgODBC 8.4.00100,has connection string like:
"Driver={PostgreSQL
Unicode};Server=localhost;Port=5432;Database=test;Uid=postgres;Pwd=XXXX;Byte
aAsLongVarBinary=1;ReadOnly=0;"
and then I open a connection as
m_pConnection->CursorLocation = adUseClient;
m_pConnection->ConnectionTimeout = 15;
m_pConnection->Open(m_pstrConn,"","",adModeUnknown);
open the recode set like
pstrSQL = _T("select * from student");
HRESULT hr =
m_pRecordset->Open(pstrSQL,_variant_t((IDispatch
*)m_pConnection,true), adOpenDynamic,adLockPessimistic,adCmdText);
and insert first new item
m_pRecordset->AddNew();
m_pRecordset->PutCollect(_T("sindex"),_bstr_t(strIndex));
...
when the debugger runs on
m_pRecordset->PutCollect(_T("sindex"),_...
it throws an com error that tells me "Mulit-step oper error, please check
the state value for each step "(Translated by my self from asian language)
the errmsg: Idispatch error #3015
I just changes the connection str to mysql, access, mssql, my code runs
well, but this exception continues occure in pgSQL, I googled for a whole
day get few help.
please ,please help me! I can insert the item in psql, and in ado with
"sprintf(sql,"insert into student(...""
however, our code has a huge amount of "AddItem,Update...",I have no time
to convert all of them to insert!
please!
