Hello! I am new to SQL so bear with me.

I am trying to get the following code to work within a system that uses Oracle for back end data services:
SELECT Retail Tran DateTime, Product Department Name, Product Quantity, Product Retail Price 
FROM Product Sales Detail 
WHERE Product Department Name = 'Meter' 
ORDER BY Retail Tran DateTime;
But I keep getting the following error message but I don't understand how there could be any problem with my FROM statement:
Oracle.DataAccess.Client.OracleException ORA-00923: FROM keyword not found where expected at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck) at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, String procedure, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, Boolean bCheck) at Oracle.DataAccess.Client.OracleCommand.ExecuteReader(Boolean requery, Boolean fillRequest, CommandBehavior behavior) at Oracle.DataAccess.Client.OracleDataAdapter.Fill(DataTable[] dataTables, Int32 startRecord, Int32 maxRecords, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataTable dataTable) at Blackboard.ReportingSystem.XmlToSql.ParseXmlToSql.ExecuteSql()
Is there any way anyone could explain what this message is even telling me?
