Problem with trigger AFTER INSERT
Hi allI am updating a column in the table by adding 2 characters 'a_' after INSERTION using the trigger.
Now when I insert data in the table a trigger is fired for INSERTION.
According to the syntax, I think that we cannot pass parameters in a trigger.
I have a test10 table that looks like this.
t1 varchar2(10)
t2 varchar2(10)
t3 varchar2(10)
t4 number
t5 number
t1 is kinda primary_key and t2 is unique though the table isn't structured like that but the data in it follows that.
The code in the trigger looks like this
CREATE OR REPLACE TRIGGER test10_t1
AFTER INSERT
ON test10
FOR EACH ROW
BEGIN
IF INSERTING THEN
UPDATE test10 SET t1 = 'a_'||:old_value WHERE t1 = ?; -- I need to mention the parameter here but not sure if we can pass param in a trigger
END IF;
END;
If I omit the WHERE clause, all records are updated. Is there another way to solve the problem?THX
Rod.
There is no need to use a clause of update.
Have you tested the relaxation that I suggested in my last post?

After an insertion in table 1, I want to take the value of the transaction and use it in a custom to insert trigger in an another datbase 2 values. One is the primary key of the table 1 transaction value and the other is a variable of the connected user's session. I can get the value of the user of the session, but I can't get the value of the transaction field.
$updateRequestDate = "INSERT INTO request_notify (id_request, username) Values ({rsrequest.id_request}," ".). $_SESSION ["kt_login_user"]. "')";
$update_result = $tNG-> connection-> execute ($updateRequestDate);
{if(!$update_result)}
$updateError = new tNG_error ("' error affecting the logged in State to N ', array(), Array();")
Return $updateError;
} else {}
return null;
}I have the custom trigger after insert transaction.
How do you get the value of a transaction for a custom trigger field?
Please try with the help of the
$tNG-> getColumnValue ("column_name")
method instead.
See you soon,.

Problems with WiFi after put 10.11.2 up-to-date.
Mid 2011 iMac. Problems with WiFi after put 10.11.2 up-to-date. No associated network. Everything was fine before the update. All the pre 10.11.2 device works fine. Anyone else having issues? I have to disconnect and reconnect manually. WiFi drops every 5 to 10 minutes. Nothing has changed on the machine something of the update.
Please do not comment on the age of the system. Achieve a Mid 2011 arrived at a possible replacement point. I have many other new Mac at home. The Mid 2011 is spec'd with 16 GB of RAM, i7 and SSD. It's always very fast.
Thank you in advance for the answer...
Hi Captainsniz
There are a few things to try. Keep doing this until the problem disappears.
First of all, if you have not already, shut down the computer completely, wait about 1 minute, then restart.
Disconnect the wifi network either via system preferences, either by pressing the "Option" key and clicking on the wifi menu bar icon.
Reset the DHCP lease by going to system preferences > network and show Advanced Options, and then click the button to "Renew the DHCP lease" TCP/IP tab.
You can delete the wifi network of system preferences > network > network name... then close system preferences. Then reopen and add the network in.
You can also restart your wifi router, it erases the old connections. Most of the routers you just turn off and wait a few minutes, then restart. You can also reset your ISP modem if you have a.
Finally, you can try to reset the PRAM and SMC on your Mac. I'll get this info here on Apple Support KBs for your particular Mac.
Be sure to back up your computer.
Hope this helps, Greg

Create a trigger that send mail with attachment after insertion of a line in Oracle APEX
I want to create an insert after trigger on a table that is to send a mail with an attachment. Here is my code.
CREATE OR REPLACE TRIGGER tr_feedback
AFTER INSERT on REVIEWS
FOR EACH LINE
DECLARE
l_id NUMBER;
BEGIN
l_id: = APEX_MAIL. SEND)
p_to => ' [email protected] ',
P_FROM = >: NEW. E-mail
p_subj = >: NEW. Object
p_body = > "Please see the attachment."
p_body_html = > ' review of < b > please < /b > the attachment ")
APEX_MAIL. ADD_ATTACHMENT (p_mail_id = > l_id,)
p_attachment = >: NEW. FILE,
p_filename = >: NEW. FILE NAME,
p_mime_type = >: NEW. MIME);
END;
But when I insert data, I get the following error:
ORA-20022: Null value provided for the parameter p_filename.
ORA-06512: at "APEX_040200.WWV_FLOW_MAIL", line 1070
ORA-06512: at "APEX_040200.WWV_FLOW_MAIL_API", line 141
ORA-06512: at "TR_FEEDBACK", line 11
ORA-04088: error during execution of trigger 'TR_FEEDBACK '.
Now, how can I fix that? Thanks in advance.
Agree with the above. Triggers (ab) should not be used in this way. Nontransactional process should not be based on a transactional trigger. These processes are part of the business logic and should be at the level of the company of codification (Summit, you can add a process to be executed once the completed insertion)

Problems with mail after switching to macOS Sierra
Hey all
After having recently upgraded to macOS Sierra, I am unable to read my mail.
I get the following error every time I check on "Get Mail".
There may be a problem with the mail server or the network. Check the account settings "*" or try again.
The server returned the error: Mail could not connect to the server 'pop1.tribcsp.com' using SSL on the default ports. Verify that this server supports SSL and that your account settings are correct.
What does this error message mean and how can I solve this problem.
Thank you
Hi Michael,
I see your message that you get an error in the mail indicating that there is a problem with the mail server or the network. To help get this problem resolved, I suggest that you follow the steps below:
If mail refers to a problem with the mail server, or the network
Mail will say that it is impossible to connect due to a problem with the mail server or the network. For example, the message may refer to a connection that has expired, or too many simultaneous connections:
If you are connected to the Internet, but the connection has expired, your email provider might be affected by a discontinuance of service. Contact them or see their status Web page to ensure that their e-mail service is online. Examples of status pages:
- iCloud mail status
- Gmail status
- Status of Yahoo mail
- Status of the AOL mail
- Status of Outlook e-mail
If the message indicates the number of simultaneous connections, too many of your devices is check your e-mail account at the same time. Quit Mail on one or more of your other devices.
If you are still unable to send or receive e-mails
- Make sure that you have installed latest version of the Mac software updates, especially if the problem occurred immediately after the installation of a previous update.
- In OS X El Capitan or later version, you can see a status icon and the short error message in the upper right of the Mail window, under the search box. The message may indicate 'Network offline' or 'Connection failed', for example. Click the message to see more details on the issue.
- Check your connection to the Mail connection doctor. It might be able to say more on the issue.
If you cannot send or receive e-mail on your Mac.
Take care.

Problems with scrolling after update
IM currently using the BlueJ ide and after updating to the new system / update (macOS Sierra) there is significant lag / jitter when scrolling. This problem only occurs when you use the scrolling with two fingers with the touch pad. When I use a mouse / or click the scroll bar on the side, it seems to go well. Not sure if there is a problem with BlueJ or the new OS. Would be very interested for some suggestions on how to fix this very annoying problem. (Using a Macbook pro 13, 2015).
Thanks a lot to all the answers
The obvious question would be if you see the problem of scrolling in Mac OS standard applications such as Mail, Notes and Safari.
If this isn't the case, it is likely BlueJ.

Big problems with fonts after upgrade to Yosemite
Hello
I upgraded my macbook pro to Yosemite for more than six months and since then, I have serious problems with application of fonts in browsers and many software I use. I googled the problem over and over again and nothing seems to help.
In general, these are the main symptoms of the problem with screenshots:
1 system ads are gibberished, or better yet, appearing with something like that, instead of letters:
2. bold letters does not at all (when I use gmail, for example) or leads to an illegible font change:
3. hyperlinks symbols on Web sites or webmail applications simply appear as empty squares and there is no way of knowing what you click on.
Bottom line: before turning to the last option and the resettlement of Yosemite, if someone could help, I'd be more than grateful.

You probably have a lot of fonts installed garbage. Follow these steps to recover your Mac for only the fonts installed in OS X.
(1) open the book fonts and choose restore fonts Standard menu. All third-party fonts will be moved out of the system and root of the fonts in the library files in a new folder next to each named (deleted) Fonts.
2) click on the desktop so Finder is the name of the app next to the Apple logo in the upper left corner. Hold down the Option key and choose go > library. This will open your user account's library folder. Create a new empty folder on the desktop. Open the folder fonts in your user account. If there is something in it, move them to the new folder on the desktop.
3) restart in Mode safe mode by rebooting and hold down the SHIFT key. When you reach the office (you need to log in Mode without failure), restart normally. Among other things, this erases all the cache files on the account of the user logged in Mode safe mode and resets the database of book of fonts for this account.
(4) clear all remaining the system font cache files. Close all the running applications. From an administrator account, open the Terminal application and enter the following command. You can also copy and paste from here in the Terminal window:
sudo atsutil databases - remove
Terminal will then ask your admin password. When you type, it will not show anything, so make sure you enter it correctly.
This command removes all the font cache files. To the system and the current connected to the user account. After you run the command, close Terminal and immediately restart your Mac.
Now test. With only fonts available provided OS and all data policies implemented cache and other such parameters cleared and reset, fonts should appear correctly in the system.
