[AccessD] Adding ADODB parameters

JR:

Try com3.Parameters("@CV").Value + com3.Parameters("@CP").Value + ...

You might also want to wrap each one in an nz() function if it is possible
for one or more parameters to be Null.

Subject: [AccessD] Adding ADODB parameters

Hi All,

Using an ADO command object to retrieve information from a SQL Server 7
stored procedure.
The command object has 3 OUTPUT parameters used to retrieve 3 values from
the stored procedure.

The command object parameters are set up as follows:
...
com3.Parameters.Append com3.CreateParameter("@CV", adDecimal, adParamOutput)
com3.Parameters("@CV").Precision = 10
com3.Parameters("@CV").NumericScale = 4

 com3.Parameters.Append com3.CreateParameter("@CP", adDecimal,
adParamOutput)
com3.Parameters("@CP").Precision = 10
com3.Parameters("@CP").NumericScale = 4

com3.Parameters.Append com3.CreateParameter("@SV", adDecimal, adParamOutput)
com3.Parameters("@SV").Precision = 10
com3.Parameters("@SV").NumericScale = 4
...

Precision and scale are set exactly the same as the stored procedure, which
is setup exactly the same as the table.

The SP runs perfectly. If I check the values in the parameters after the SP
runs, I get the desired values.

The problem is that if I tried to perform the calculation:
com3.Parameters("@CV") + com3.Parameters("@CP") + com3.Parameters

I get a type mismatch error. If I cast all 3 parameters to type Double
before the calculation, it works fine.

Can I not do this?

Thanks
JR
