This sample demonstrates usage of
Item property. It retrieves data from a column of composite type in a table and renders the data to console. To run the samples successfully you have to create server objects with the following script: CREATE TYPE tperson AS (name text, age integer); CREATE TABLE personnel (id integer, person tperson);
static void ReadData(PgSqlConnection conn)
{
string str = "SELECT * FROM personnel";
PgSqlCommand pgCommand = new PgSqlCommand(str,conn);
PgSqlDataReader pgReader = pgCommand.ExecuteReader();
while (pgReader.Read())
{
Console.Write(pgReader.GetInt32(0) + "\t");
PgSqlRow pgRow = pgReader.GetPgSqlRow(1);
if (pgRow == null)
{
Console.WriteLine();
continue;
}
Console.Write(pgRow[0] + "\t");
Console.WriteLine(pgRow["age"]);
}
pgReader.Close();
}
Sub ReadData(ByVal conn As PgSqlConnection)
Dim str As String = "SELECT * FROM personnel"
Dim pgCommand As PgSqlCommand = New PgSqlCommand(str, conn)
Dim pgReader As PgSqlDataReader = pgCommand.ExecuteReader()
While pgReader.Read()
Console.Write(pgReader.GetInt32(0) & Chr(9))
