    Syntax
    Remarks

    Parameter names are not case-sensitive.

    Refer to article Using Parameters in dotConnect for PostgreSQL to obtain detailed information on the matter together with some advanced examples.

    Example
    The following example creates multiple instances of PgSqlParameter through the PgSqlParameterCollection within the PgSqlDataAdapter. These parameters are used to select data from PostgreSQL and place the data in the System.Data.DataSet. This example assumes that a System.Data.DataSet and a PgSqlDataAdapter have already been created with the appropriate schema, commands, and connection.
    public void AddPgSqlParameters()
    {
      // ...
      // create myDataSet and myDataAdapter
      // ...
      myDataAdapter.SelectCommand.Parameters.Add("DName", PgSqlType.VarChar, 15).Value = "DEVELOPMENT";
      myDataAdapter.SelectCommand.Parameters.Add("DeptNo", PgSqlType.Int).Value = 50;
      myDataAdapter.Fill(myDataSet);
    }
    Public Sub AddPgSqlParameters()
      ' ...
      ' create myDataSet and myDataAdapter
      ' ...
      myDataAdapter.SelectCommand.Parameters.Add("DName", PgSqlType.VarChar, 15).Value = "DEVELOPMENT"
      myDataAdapter.SelectCommand.Parameters.Add("DeptNo", PgSqlType.Int).Value = 50
      myDataAdapter.Fill(myDataSet)
    End Sub
