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.

csharp

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);
}

Visual Basic

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
