SQL Server UPDATE Command Fails without error

Using SSMS running the below UPDATE command I get returned message says 1 row affected. but if I then follow it up with a Select and it shows that the row never updated.

This issue happens in SSMS and a custom application I built in C# using Entity Framework. I have since stopped using Entity Framework generated code and moved straight to a stored proc. All of 3 different ways of performing the same task I randomly get this issue. Sometimes it can be 100’s or 1000’s of updates before the issue happens again or it could be a few updates later it happens again. I have run UPDATE STATISTICS, I have Rebuilt Indexes and Reorganized Indexes.

As a side note, I NEVER have an issue with INSERTs only UPDATEs we never DELETE any records. and total record count on the table is 201,741

UPDATE CreativeWorkFlowQueue     SET CurrentIndicator = 'N' WHERE CreativeWorkFlowQueueId = 198231  SELECT * FROM CreativeWorkFlowQueue WHERE CreativeWorkFlowQueueId = 198231

enter image description here

here is the table

SET ANSI_NULLS ON GO  SET QUOTED_IDENTIFIER ON GO  CREATE TABLE [dbo].[CreativeWorkFlowQueue](     [CreativeWorkFlowQueueId] [int] IDENTITY(1,1) NOT NULL,     [DigitalCampaignCreativeId] [int] NOT NULL,     [WorkFlowQueueId] [int] NOT NULL,     [CurrentIndicator] [char](1) NOT NULL,     [CreateDate] [datetime] NOT NULL,     [LastUpdatedDate] [datetime] NOT NULL,     [IsDeleted] [bit] NOT NULL, PRIMARY KEY CLUSTERED  (     [CreativeWorkFlowQueueId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue] ADD  CONSTRAINT [CreateDate defaults to utcDate on CreativeWorkFlowQueue]  DEFAULT (getutcdate()) FOR [CreateDate] GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue] ADD  CONSTRAINT [LastUpdatedDate defaults to utcDate on CreativeWorkFlowQueue]  DEFAULT (getutcdate()) FOR [LastUpdatedDate] GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue] ADD  CONSTRAINT [DF_CreativeWorkFlowQueue_IsDeleted]  DEFAULT ((0)) FOR [IsDeleted] GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue]  WITH CHECK ADD  CONSTRAINT [CreativeWorkFlowQueue DigitalCampaignCreativeId fk] FOREIGN KEY([DigitalCampaignCreativeId]) REFERENCES [dbo].[DigitalCampaignCreative] ([DigitalCampaignCreativeId]) GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue] CHECK CONSTRAINT [CreativeWorkFlowQueue DigitalCampaignCreativeId fk] GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue]  WITH CHECK ADD  CONSTRAINT [CreativeWorkFlowQueue WorkFlowQueueId fk] FOREIGN KEY([WorkFlowQueueId]) REFERENCES [dbo].[WorkFlowQueue] ([WorkFlowQueueId]) GO  ALTER TABLE [dbo].[CreativeWorkFlowQueue] CHECK CONSTRAINT [CreativeWorkFlowQueue WorkFlowQueueId fk] GO

EDIT Adding the Stored Proc that also has the same issue.

I did not include this stored proc simply due to the fact that it is complex and if a simple update doesn’t work I figured start there first.

PostgreSQL connection URI fails, but parameters work

Running postgreSQL 13.2 with ssl on.

I need to connect to a database from a third party application that requires a connection URI, but it is not working. So I tested connecting with psql using two different formats with the same credentials. One worked and one didn’t.

The following command logs me into mydb as user myuser:

# psql -U myuser -d mydb -h 127.0.0.1 -p 5432 -W Password: psql (13.2 (Debian 13.2-1.pgdg100+1)) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off) Type "help" for help.  mydb=>

However this command fails:

# psql postgresql://myuser:MYPASSWORD@127.0.0.1:5432/mydb?sslmode=require psql: error: FATAL: password authentication failed for user "myuser"

I am using exactly the same credentials. I’ve verified it more than 10 times. Removing "sslmode=require" does not fix the problem.

My pg_hba.conf file contains:

host   mydb   myuser   127.0.0.1/32   password

I made it the first line in my pg_hba.conf file, so it can’t be getting hung up on any other line.

What am I doing wrong?

Woocommerce custom script ajax post form data fails to be captured in backend

I am using woocommerce and I wanna customize admin page’s coupon section.

So I use the following code snippet such that I can write my own codes in my_script.js.

add_action('admin_enqueue_scripts', 'add_custom_js_file_to_admin'); function add_custom_js_file_to_admin($  hook) {     $  screen = get_current_screen();     if ( 'shop_coupon' === $  screen->id ) {         wp_enqueue_script('my_script', plugin_dir_url(__FILE__) . 'js/my_script.js');     } }

I am successful to create a new custom field: Taxonomy as shown in the pic below. And ajax post request’s header indicates that the data should be sent correctly (the red box in the pic). I am

However, my backend code snippet below fails to retrieve the data from the post request ( eg: $ tax below is null):

add_action('woocommerce_coupon_options_save', 'save_coupon_text_field', 10, 2); function save_coupon_text_field($  post_id, $  coupon)     {       $  tax = $  _POST['wc_sc_taxonomy_restrictions[0][tax]'];       $  coupon->update_meta_data('taxonomy_tax', $  _POST['wc_sc_taxonomy_restrictions[0][tax]']);       $  coupon->update_meta_data('taxonomy_op', $  _POST['wc_sc_taxonomy_restrictions[0][op]']);       $  coupon->save();     }

I got 2 questions:

(1) Can someone kindly share any idea on what’s wrong with my codes above?

(2) In the custom script my_script.js, I wanna call an api which serves to retrieve data from my database; the data will then be used as the options available for the taxonomy’s drop-down select box. Can anyone tell me how I can do so in my_script.js? Normally in my BE php file, I wrote sth like below, yet I don’t know how I can perform sth similar in my custom script:

 global $  wpdb;  $  result = $  wpdb->get_results('some sql here');

How to know when Findroot fails to find a solution

My problem is very simple. Assume you have this piece of code :

FindRoot[{x^2 + 1 == 0}, {x, -1, 1}]

Now, this code returns

FindRoot::cvmit: Failed to converge to the requested accuracy or precision within 100 iterations. {x -> -1.}

Which is as expected since the equation has no real root. Now my question is, how can I get the fact that FindRoot failed in a variable ? Say I want to display a message "Failed search", when FindRoot fails for whatever reason, how do I collect the fact that the function failed ? I was looking into Catch[], but it seems that no exception is thrown.

What happens when an unconscious creature fails their saving throw against a Banshee’s Wail?

A Banshee (MM, p. 23) has the Wail action:

Wail (1/Day). The banshee releases a mournful wail, provided that she isn’t in sunlight. This wail has no effect on constructs and undead. All other creatures within 30 feet of her that can hear her must make a DC 13 Constitution saving throw. On a failure, a creature drops to 0 hit points. On a success, a creature takes 10 (3d6) psychic damage.

If someone was already at 0 hit points (for example, having failed their saving throw against a different Banshee’s Wail), what would happen if they fail their saving throw against this Banshee’s Wail (assuming they still need to make a saving throw)?

  • The unconscious creature takes one step towards death, as though they took damage (thus making the saving throw meaningless, since they’d take a step towards death either way);
  • The unconscious creature just dies (unlikely, but in case there’s something written that would imply this hidden in the rules somewhere);
  • Nothing, since this isn’t damage, its just an effect (meaning the unconscious creature would be better off failing this save than passing in this case!)
  • Something else…

Settings API: Setting default option via ‘get_option’ fails

  1. All my options are stored in one array test_hs_options
  2. I have select list settings field ( test_hs_options['duration_months'] ) which stores the selected month (1-12).
  3. For this settings field, I would like to set a default option at 5.
  4. All my attempts at setting the default have failed.
  5. What am I missing?

Stored procedure runs fine when executed manually but fails in scheduled job

I have a stored procedure that runs fine when executed manually but fails in scheduled job. The error I receive is: Executed as user: \USER-a. Login failed for user ‘\USER-a’. [SQLSTATE 28000] (Error 18456). The step failed.

My other stored procedures runs fine when scheduled. The only stored procedures that fails are the ones that are written in this form.

In Pathfinder 2e, if a 20th level caster fails to learn a spell, can they never try again?

On page 238 of the Core Rulebook, under "Learn a Spell", the rules state:

Failure You fail to learn the spell but can try again after you gain a level. The materials aren’t expended.

Since character level is capped at 20th, does this mean that a 20th level caster who fails to Learn a Spell can never try to learn that spell again?

Decrypting a password-protected 7z file with Delta filter fails

I have made a 7z archive using Delta filter containing a wav file and I have protected it with a password. I am running a terminal in Kali Linux. My problem is that I cannot get the password cracked using 7z2john.pl and john the ripper. If I omit the Delta compression, using only the default compression of 7z, then the cracking succeeds. My question: is it possible to use 7z2john.pl and john the ripper to crack a password-protected 7z file with Delta compression? If it is possible, how can it be done?

Here are the steps to reproduce the problem:

  1. I use the following command to create the archive:

7z a test.7z *.wav -mf=Delta:4 -peasy

I get this output:

7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21 p7zip Version 16.02 (locale=fi_FI.utf8,Utf16=on,HugeFiles=on,64 bits,4 CPUs Intel(R) Core(TM) i5-4460  CPU @ 3.20GHz (306C3),ASM,AES-NI)  Open archive: test.7z -- Path = test.7z Type = 7z Physical Size = 1090 Headers Size = 162 Method = Delta LZMA2:15 7zAES Solid = - Blocks = 1  Scanning the drive: 1 file, 32080 bytes (32 KiB)  Updating archive: test.7z  Items to compress: 1       Files read from disk: 1 Archive size: 1090 bytes (2 KiB) Everything is Ok
  1. I use 7z2john.pl to generate material for John the Ripper to crack the archive:

/usr/share/john/7z2john.pl test.7z > test.hash

  1. I create a word list file containing only the password I gave to the archive:

echo easy > wordlist.txt

Then I try to decrypt the file:

sudo john test.hash --wordlist=wordlist.txt

I get the following output:

Using default input encoding: UTF-8 Loaded 1 password hash (7z, 7-Zip [SHA256 256/256 AVX2 8x AES]) Cost 1 (iteration count) is 524288 for all loaded hashes Cost 2 (padding size) is 3 for all loaded hashes Cost 3 (compression type) is 2 for all loaded hashes Will run 4 OpenMP threads Press 'q' or Ctrl-C to abort, almost any other key for status Warning: Only 1 candidate left, minimum 32 needed for performance. 0g 0:00:00:00 DONE (2020-08-15 07:37) 0g/s 5.555p/s 5.555c/s 5.555C/s easy Session completed
  1. I check if the password has been cracked: sudo john --show test.hash

I get the following output:

0 password hashes cracked, 1 left

So it seems that the decrypting did not succeed. However, I can extract the archive using command 7z e test.7z -peasy so the password should be correct. Also, if I create the archive without specifying the Delta filter using command 7z a test.7z *.wav -peasy. That way, by repeating the steps 1-4 I get the password cracked and am shown the result that the correct password has been found:
