OdbcParameterCollection Class

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

Namespace: System.Data.Odbc
Assembly: System.Data (in

Public NotInheritable Class OdbcParameterCollection
	Inherits DbParameterCollection
Dim instance As OdbcParameterCollection

public final class OdbcParameterCollection extends DbParameterCollection
public final class OdbcParameterCollection extends DbParameterCollection

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

The following example assumes that the data source has a table name MoneyTable and a stored procedure named MoneyProcedure, which are defined as:

CREATE TABLE MoneyTable (col1 int, col2 smallmoney, col3 decimal);

CREATE PROC MoneyProcedure (@p1 int, @p2 smallmoney, @p3 decimal) 
INSERT INTO MyTable VALUES (@p1, @p2, @p3);

The example creates parameters and calls the MoneyProcedure stored procedure.

Public Sub ExecuteStoredProcedure(connection As OdbcConnection)
    Dim command As OdbcCommand = connection.CreateCommand()
    command.CommandText = “{ call MoneyProcedure(?,?,?) ”

    command.Parameters.Add("", OdbcType.Int).Value = 1
    command.Parameters.Add("", OdbcType.Decimal).Value = 2
    command.Parameters.Add("", OdbcType.Decimal).Value = 3
End Sub
