ADO.NET Provider for Neo4j

Build 24.0.9060

Result Sets

You can access the same column information about the results of a query that you can for table schemas. See Columns for the columns returned.

Retrieving Result Set Metadata

You can use the GetSchemaTable method of the Neo4jDataReader to retrieve result set metadata. Call GetSchemaTable after calling ExecuteReader.

Each row of the DataTable describes a column in the query's result.

C#

string connectionString = "server=localhost;port=7474;user=neo4j;password=password;";

using (Neo4jConnection conn = new Neo4jConnection(connectionString)) {
  Neo4jCommand cmd = new Neo4jCommand("SELECT * FROM ProductCategory WHERE CategoryOwner = 'Bob'", conn);
  Neo4jDataReader rdr = cmd.ExecuteReader();
  DataTable schemaTable = rdr.GetSchemaTable();
  foreach (DataRow row in schemaTable.Rows) {
    foreach (DataColumn col in schemaTable.Columns) {
      Console.WriteLine("{0}: {1}", col.ColumnName, row[col]);
    }
  }
}

VB.NET

Dim connectionString As String = "server=localhost;port=7474;user=neo4j;password=password;"

Using conn As New Neo4jConnection(connectionString)
  Dim cmd As New Neo4jCommand("SELECT * FROM ProductCategory WHERE CategoryOwner = 'Bob'", conn)
  Dim rdr As Neo4jDataReader = cmd.ExecuteReader()
  Dim schemaTable As DataTable = rdr.GetSchemaTable()
  For Each row As DataRow In schemaTable.Rows
    For Each col As DataColumn In schemaTable.Columns
      Console.WriteLine("{0}: {1}", col.ColumnName, row(col))
    Next
  Next
End Using
