OdbcParameter.ParameterName Property

Gets or sets the name of the OdbcParameter.

Namespace: System.Data.Odbc
Assembly: System.Data (in system.data.dll)

public override string ParameterName { get; set; 
/** @property */
public String get_ParameterName ()

/** @property */
public void set_ParameterName (String value)

public override function get ParameterName () : String

public override function set ParameterName (value : String)

Property Value

The name of the OdbcParameter. The default is an empty string ("").

Instead of named parameters, the ODBC .NET Provider uses positional parameters that are marked with a question mark (?) in the syntax of the command text. Parameter objects in the OdbcParameterCollection and the actual parameters accepted by the stored procedure or parameterized SQL statement correspond to each other based on the order in which the OdbcParameter objects are inserted into the collection instead of by parameter name. Parameter names can be supplied, but will be ignored during parameter object binding.

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)

The following example creates parameters and calls the MyProc stored procedure:

[Visual Basic]

Public Sub CreateMyProc(connection As OdbcConnection)

   Dim command As OdbcCommand = connection.CreateCommand()

   command.CommandText = “{ call MyProc(?,?,?) ”
   command.Parameters.Add("", OdbcType.Int).Value = 1
   command.Parameters.Add("", OdbcType.Decimal).Value = 2
   command.Parameters.Add("", OdbcType.Decimal).Value = 3

End Sub

[C#]

public void CreateMyProc(OdbcConnection connection) 
{
   OdbcCommand command = myConnection.CreateCommand();

   command.CommandText = "{ call MyProc(?,?,?) ";
   command.Parameters.Add("", OdbcType.Int).Value = 1;
   command.Parameters.Add("", OdbcType.Decimal).Value = 2;
   command.Parameters.Add("", OdbcType.Decimal).Value = 3;
