Test if a dynamic query returns 0 results

Hi, what’s the best way to check if your query return 0 records?

If $$$ISOK(sc) 	
    		{
   	   		 	Set tResult = sqlStatement.%Execute()
   	    
    			WHILE tResult.%Next()
    			{
					set tRecords = tResult.%ROWCOUNT
   		        }

				if (tRecords = "")
				{
					write "no records" 
				}
			}
