Passing parameter for Stored Procedure to Data Adapter/Data Set

[Guest]

Hey all,

I'm trying to pass a parameter into my Stored procedure to be accessed by
my data adapter into a dataset

db2.AddParameter("@intClientID",
cmbClientList.SelectedValue.ToString());
DataSet rsDataset = db2.Fill("spListMappingDetails",
CommandType.StoredProcedure);

However, when i try to run it, it gives me an error

{"Procedure 'spListMappingDetails' expects parameter '@intClientId', which
was not supplied."}

Any help is appreciated.

I used a executescalar and executequery function and it has no problem.

thanks in advance

While your code creates the parameter, it does not set the Value property.

This cmbClientList.SelectedValue.ToString() is suppose to be my value, how
else should i set the value?

Thanks

Sorry, I blinked and missed it.
The Fill method is executed off the DataAdapter--not the Command. It expects
a SelectCommand to be populated with the CommandText that has the SQL SELECT
query and the SelectCommand.Parameters collection to be populated with
Parameters. Let's see the real code.

DataSet d = new DataSet("DataSet");
IDataAdapter apt = IDataAdapter GetAdapter(<SqlStatement>,
CommandType.StoredProcedure );

apt.Fill(d);
return d;

I don't know why you're using this approach. I also don't see a GetAdapter
in the Framework object browser so it must be in the DAB or in some custom
libary. I can offer help on more conventional means, but not on this...

Hi,

First:
I do not believe that parameter names are case insensitive. Did you try
adding parameter as '@intClientId' instead of '@intClientID'

db2.AddParameter("@intClientId",cmbClientList.SelectedValue.ToString());

Second:
to be sure the cmbClientList has a selected value, try using a string
variable to get the cmbClientList.SelectedValue.ToString and (after) use
the string variable as argument for AddParameter:

mystring = cmbClientList.SelectedValue.ToString()
db2.AddParameter("@intClientId",mystring);

hope this will help

Just curious, how different is it to pass a parameter to a data adapter as
compared to a Recordset (i.e data reader)

 

[William \(Bill\) Vaughn]

I don't know what planet you're getting your examples, but you can't pass a
parameter to a DataAdapter--only to the Command objects it manages. There is
no Recordset in the SqlClient namespace and the DataReader is a returned
data stream, not a way to execute SQL--that can only be done with a Command.

Thanks. That cleared things out for me. I'm new to all this, just got
confused. Will try to work it out.

Basically this is what i am working with:-

protected internal abstract IDbDataParameter GetParameter(string name,
object val);

public virtual void AddParameter(string name, object val)
{
if (Command == null) { ResetCommand(); }
if (val == null) { val = DBNull.Value; }
Command.Parameters.Add(GetParameter(name, val));
}

protected abstract IDataAdapter GetAdapter(string sql, CommandType type);

public virtual DataSet Fill(string sql, CommandType type)
{
DataSet d = new DataSet("DataSet");
IDataAdapter apt = GetAdapter(sql, type);
apt.Fill(d);
return d;
}


dbConnection.AddParameter("@<Parameter>", "<Value>");
DataSet rsDataset = dbConnection.Fill("<StoredProcedure>",
CommandType.StoredProcedure);
