plsql - Oracle PL/SQL Trigger to limit orders per customer -

-

Just working on creating a little trigger What I'm doing to trigger this trigger is making sure that the customer Only one current time can get 10 orders in the order table, in order. Do not ask why my idiot wants me to feel silly.

But originally a trigger placed order is on the table, I am currently selecting a different number on customer_ID and it has a V_count version. 

  If v_count & lt; Enter 10 INSERT__ ELSE DBMS_OUTPUT.PUT_LINE ('Please wait 10 or more order processing for you') END END   
 This code is the original gist but it will not run if any If so, can I show the full code?  
 Here's the code - Sorry, I just do not know how to use SQLFeed now.  
  To change or change the trigger, select each line for the v_count number is put before trg_order_limit before the first INR; SELECT COUNT (DISTINCT FK1_customer_id) from place_order in V_count; If v_count & lt; 10th put order_order (order_dard, order_date, delivery_date, fk1_graher_id, fk-2_morifier_id, fk3_order_type_id) value (new order_id ,: new order_date, new delivery_date, newfac 1_group_id, newfac2 employee - ID ,: NewFK3_Der_type_ID); ELSE v_count & gt; 10 then DBMS_OUTPUT.PUT_LINE ('You currently have 10 or more order processing.'); end if; End;   
 When I run the script in Oracle, I get an error on line 4: PL / SQL: ORA-0933: SQL command did not end properly  
 lot Thank you very much Richard   
 
 
 Even if there was no syntax error in your trigger, then this work Will not: Only the output "can not order more than 10" message and insertion will still proceed; In addition, if you passed this exam, you would be put in a loop of inserts. In the event of a lot of records, you need to throw exceptions, and you need to catch your application, and it is nothing to go through the test.  
 For the error, I think the problem is with this line:  
  from SELECT COUNT (DISTINCT FK1_customer_id) in place_order in v_count;   
 It should be:  
  placed SELECT COUNT (DISTINCT FK1_customer_id); in the v_count line;   
 However, this question is wrong anyway: it will return the number of unique customers who order it. What you are looking for is:  
  Select parentheses_elect in the v_count direction where fk1_customer_id =: new.fk1_customer_id   
 that  order_id < There is a specificity barrier in / code>; Which seems likely! However, your trigger code should be something like this:  
  Announce the v_count number to trigger or change trg_order_limit before entering the placed_order for each row; Start - get calculation count (order_ID) of the current order count placed in v_count / command where fk1_customer_id =: new.fk1_customer_id; - Increase exception if there are too many if v_count & gt; = 10 raise_application_error (-20000, 'you currently have 10 or more order processing.'); end if; End;   
 However, this approach is probably not a good idea.  
 
  Edit  The number of orders per customer is completely incorrect. My answer was updated.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from.
