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 SquareDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MyApplicationSecret;CallbackURL=http://localhost:33333;LocationId=MyDefaultLocation"; using (SquareConnection conn = new SquareConnection(connectionString)) { SquareCommand cmd = new SquareCommand("SELECT * FROM Payments WHERE Id = 'Jq74mCczmFXk1tC10GB'", conn); SquareDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MyApplicationSecret;CallbackURL=http://localhost:33333;LocationId=MyDefaultLocation" Using conn As New SquareConnection(connectionString) Dim cmd As New SquareCommand("SELECT * FROM Payments WHERE Id = 'Jq74mCczmFXk1tC10GB'", conn) Dim rdr As SquareDataReader = 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
