OdbcParameterCollection Class

Note: This namespace, class, or member is supported only in version 1.1 of the .NET Framework.

Represents a collection of parameters relevant to an OdbcCommand as well as their respective mappings to columns in a DataSet. This class cannot be inherited.

For a list of all members of this type, see OdbcParameterCollection Members.

[Visual Basic]
NotInheritable Public Class OdbcParameterCollection
   Inherits MarshalByRefObject

[C#]

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

The number of parameters in the collection must be equal to the number of parameter placeholders within the command text, or the .NET Framework Data Provider for ODBC raises an error.

Example

[Visual Basic, C#, C++] The following example assumes that the data source has a table name MyTable and a stored procedure named MyProc, that is defined as:

create table MyTable (col1 int, col2 smallmoney, col3 decimal)
create proc MyProc (@p1 int, @p2 smallmoney, @p3 decimal) as insert into MyTable values (@p1, @p2, @p3)
   

[Visual Basic, C#, C++] The example creates parameters and calls the MyProc stored procedure.

[Visual Basic] 
Public Sub CreateMyProc(myConnection As OdbcConnection)

    Dim myCommand As OdbcCommand = myConnection.CreateCommand()
    myCommand.CommandText = { call MyProc(?,?,?) }

    myCommand.Parameters.Add("", OdbcType.Int).Value = 1
    myCommand.Parameters.Add("", OdbcType.Decimal).Value = 2
    myCommand.Parameters.Add("", OdbcType.Decimal).Value = 3

End Sub ' CreateMyProc

[C#] 
public void CreateMyProc(OdbcConnection myConnection) 
{
    OdbcCommand myCommand = myConnection.CreateCommand();
    myCommand.CommandText = "{ call MyProc(?,?,?) }";

    myCommand.Parameters.Add("", OdbcType.Int).Value = 1;
    myCommand.Parameters.Add("", OdbcType.Decimal).Value = 2;
    myCommand.Parameters.Add("", OdbcType.Decimal).Value = 3;
}

[C++] 
public:
void CreateMyProc(OdbcConnection* myConnection) 
{
    OdbcCommand* myCommand = myConnection->CreateCommand();
    myCommand->CommandText = S"{ call MyProc(?,?,?) }";

    myCommand->Parameters->Add(S"", OdbcType::Int)->Value = __box(1);
    myCommand->Parameters->Add(S"", OdbcType::Decimal)->Value = __box(2);
    myCommand->Parameters->Add(S"", OdbcType::Decimal)->Value = __box(3);
}
