Call Stored Procedures via ADO

Hello everyone

I want to call a DB2 7.2 stored procedure via ADO in VC++ 7.1
It has 4 parameters, the 1st and the 4th are OUTPUT and the others are INPUT
params.

My code looks like this:
(spCMD is a Command, spCON a Connection, spRS a Resultset, and spPARAM
are Parameters)
spCMD->Name = "mySPname";
spCMD->ActiveConnecti on = spCON;
spCMD->CommandText = "CALL SYSPROC.mySPnam e(?, char('a string',8),
char('31.10.200 3',10), ?)";
spPARAM1 = spCMD->CreateParamete r("RETCODE", adSmallInt,
adParamOutput, 2, NULL);
spCMD->Parameters->Append(spPARAM 1);
spPARAM2 = spCMD->CreateParamete r("RETCHAR", adChar,
adParamOutput, 2, NULL);
spCMD->Parameters->Append(spPARAM 2);
spRS = spCMD->Execute(NULL , NULL, adCmdText);

When I execute I have the following error message:
[IBM][CLI Driver][DB2] SQL0440N No function by the name "mySPname"
having compatible arguments was found in the function path SQLSTATE=42884

The following SQL command works in DB2 Command Center:
CALL SYSPROC.MYSPNAM E(?, 'a string', '31.10.2003', ?)
It displays the 2 output params correctly.
I've checked in DB2: the SP prototype is (OUT SmallInt, IN Char 8, IN Char
10, OUT Char 2).
So I guess my problem has to do with using ADO correctly... With a simple
SELECT statement it works fine.
So what did I do wrong with a parameterized stored procedure?

Chris

Here's a chunk of code I use to call a stored proc with in and out
variables :
One of the key things - CLOSE the recordset BEFORE using the return
value(s)

Public Function GetNewKeyValue( sTableName As String) As Long

Dim rstSequence As ADODB.Recordset
Dim cTmp As New ADODB.Connectio n
Dim lNewKey As Long
Dim sSeq As String
Dim cmd As New ADODB.Command
Dim parm1 As New ADODB.Parameter
Dim parm2 As New ADODB.Parameter
Dim nCount As Integer

lNewKey = 0
nCount = 0
On Error GoTo Err_GetNewKeyVa lue

repeat_call:
nCount = nCount + 1
cTmp.Connection String = sConnectString
cTmp.CursorLoca tion = adUseClient
cTmp.Open

cmd.ActiveConne ction = cTmp
cmd.CommandText = "KWOOD.GETNEWKE Y"
cmd.CommandType = adCmdStoredProc

Set parm1 = cmd.CreateParam eter("Sseq", adVarChar, adParamInput,
30, sTableName)
cmd.Parameters. Append parm1
Set parm2 = cmd.CreateParam eter("lKeyValue ", adBigInt,
adParamOutput, 8)
cmd.Parameters. Append parm2

Set rstSequence = cmd.Execute
Set rstSequence = Nothing

lNewKey = cmd(1).Value

Thanks for your reply!

I've found out that I can execute the stored procedure if I set every
parameter
spCMD->CommandText = "CALL SYSPROC.ST1RTCH ECKBEZMM(?, ?, ?, ?)";

But there is another problem when I try to get the return values of the
parameters...

After I've called Execute the recordset is in a closed state already:
spRS = spCMD->Execute(NULL , NULL, adCmdText);
(spRS->State == adStateClosed)

In C++ it seems I cannot access the parameters collection as easily as you
do in VB.
I tried the get_item method but I always get a NULL pointer :-(

Chris

I can't help you with C++, I know there certainly was some putz work
in getting VB to work...

I want to write function to call another function which name is parameter to first function. Other parameters should be passed to called function.
