the following is my table, each transaction happened will record in this table. now I want get some analysis data by SQL, requirement as below:
Requirement 1:
1, obtain all total of transcation total request, just SQL as: select sum("Total_Requests") as "Total_Trans_Reqs" from "Transaction"
2, obtain each sum of each transaction total request, SQL as: select "Transaction", sum("Total_Request") as "Single_Trans_Total_Reqs" from "Transaction" group by "Transaction"
3, this percent is what I need, "Single_Trans_Total_Reqs" / "Total_Trans_Reqs" = ?%
how could I write it in one SQL to run and get this result for my program. many thanks?
Requirement 2:
1, obtain all "Transaction“ happen times: SQL as: select count("Transaction") as "All_Trans_Total_count" from "Transaction"
2, obtain each "Transaction" happen times, SQL as: select "Transaction", count("Transaction") as "Singe_Trans_count" from "Transaction" group by "Transaction"
3, the percent is what I want: "Single_Trans_count" / "All_Trans_Total_count" = ?%
table "Transaction" ("Transaction" VARCHAR(128) ,
"Timestamp" CHAR(16) ,
"Data_Interval" INTEGER ,
"Percent_Failed" DECIMAL(31,3) ,
"Percent_Slow" DECIMAL(31,3) ,
"Percent_Good" DECIMAL(31,3) ,
"Percent_Available" DECIMAL(31,3) ,
"Average_Response_Time" DECIMAL(31,3) ,
"Failed_Requests" INTEGER ,
"Total_Requests" INTEGER ,
"Slow_Requests" INTEGER ,
"Good_Requests" INTEGER ,
"Data_Collector_Type" VARCHAR(32) ,
"Rank" DECIMAL(31,3) ,
"Total_Server_Response_Time" DECIMAL(31,3) ,
"Total_Connect_Time" DECIMAL(31,3) ,
"Total_DNS_Time" DECIMAL(31,3) ,
"Total_Resolve_Time" DECIMAL(31,3) ,
"Average_Server_Response_Time" DECIMAL(31,3) ,
"Average_Connect_Time" DECIMAL(31,3) ,
"Average_DNS_TIME" DECIMAL(31,3) ,
"Average_Resolve_Time" DECIMAL(31,3) )

select x.transaction,(single_trans_total_reqs*100.00)/total_trans_req
,(single_trans_count*100.00)/all_trans_total_count
from (
select sum(total_requests) as Total_trans_reqs
,count(*) as all_trans_total_count
from transaction
) as Y.
(
select a.transaction,sum(total_requests) as single_trans_total_reqs
,count(*) as single_trans_count
from transaction as a
group by a.transaction

order by 1
