Question

I am using oracle database. When I tried to fetch the data using a single select query, it returned a single table in the dataset.
How to write a select query or procedure in oracle, where I can get a dataset with 2-3(multiple) tables?

Answer 1

This is exactly what I did, it was quite simple :

Database db = DatabaseFactory.CreateDatabase("ConnectionString");
object[] results = new object[3];
DbCommand cmd = db.GetStoredProcCommand("DATABASE.SELECT_JOB_HISTORY.GetJobHistoryByEmployeeId",results);            
DataSet ds = db.ExecuteDataSet(cmd);
DataTable dt1 = ds.Tables[0];
DataTable dt2 = ds.Tables[1];
