sql - combining two queries -

-

This first query captures all transactions_details for a specific date range, it is difficult, however, Need the amount in the query if it does have any meaning. 

  SELECT td.transaction_id, sum (IF (Sahara (ti.na, -1) = 0 and covalent (ti.special_info_type, -1) = 0 and insert (ti.item_type, ' '=' P 'and organized (ti.comp_id, 0) & lt; = 0, organized (disc_amt, 0), 0)) disc_sum, sum (IF (insert (as ti.na, -1) = 0 and organized (ti.special_info_type, -1) = 0 and organized (ti.item_type, '') = 'P' and organized (ti.comp_id, 0) & gt; 0, organized (comp_amt, 0), 0) ) CSM, as the amount (if (insert (ti.na, -1) = 0 and organized (ti.special_info_type, -1) = 0 and organized (ti.item_type, '') = 'P' and organized ( Ti.comp_id, 0)> 0, (Comp_tax, 0) inserted, 0)) ctx form transaction_details to include td left externally Ti.transaction_id = td.transaction_id on transaction_items ti td.na = 0 and td.entry_TS & gt; =? And td.entry_TS & lt; ? TD by Group Transaction_id;

This query is executed in the loop for each transaction returned from the previous query. RefAmt, collect (sum (x.efftax) as the syLECT count (x.id) refCnt, as syndication (sum (X.item_price + x.sub_price), 0) , 0) as Rifaks (SELECT (tiP.item_price - tiP.comp_amt) as item_price, consolidate (sum (tiA.item_price), 0) as sub_price, (tiP.efftax - tiP.comp_tax) as efftax, transaction_items fresh tiP.id join left outer (tiP.id = tiA.ref_id and tiA.item_type = 'a' and Tia transaction_items Tia. na = 0) where tiP.item_type = 'p 'And tiP.na = 0 and tiP.refund = 1 #and tiP.transaction_id = tiP.transaction_id, tiP.order_id) by the group as tiP.id by x;

First of all, you query your COALESCE .

NULL values ​​do not contribute to SUM in your argument, so you can quickly filter them: 

  SELECT td Transaction_id, SUM (IF (ti.comp_id & lt; 0 or ti.comp_id IS nULL, Disk_amti, 0), SM (IF (TI Coppeediaidi & gt; 0, COMP_AMT, 0), SM (IF (TI Copas_aidi & gt; 0 ), Comp_tax, 0) transaction_details td from LEFT OUTER Join transaction_items ti oN ti.transaction_id = td.transaction_id WHERE td.entry_TS & gt; =? aND td.entry_TS & lt ;? aND ti.na = 0 and ti.special_info_type = 0 and TI .item_type = 'T' by T.R. Transaction_ID;

second, SUM lower Is a Uetative, i.e. SUM code> SUM s is a SUM contribution values.

You can use intermediate SUM 'S.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
