DBA stands for Dynamic Time Warping Barycenter Averaging. DBA is an averaging method that is consistent with Dynamic Time Warping. I give below an example of the difference between the traditional arithmetic mean of the set of time series and DBA.

QUESTION
I try installing Informix with PDO locally and on docker, each way leads to the same failing tests.
I'm not sure if 'just' the tests are failing because some configuration would be needed to make them run, while the client / pdo would work fine if I start working on these.
Update:
It turns out that the PDO works even though the make test all fail.
Meaning with below Dockerfile it is possible to spin up a PHP-8.0 Informix 4.50 PDO_INFORMIX 1.3.6 container (you need to download the IBM Informix CSDK and the PDO first)
Dockerfile

QUESTION
I have a requirement to build a SSIS package that sends HTML formatted emails and then saves the emails as tiff files. I have created a script task that processes the necessary records and then coverts the HTML code to the tiff. I have split the process into separate packages, the email send works fine the converting HTML to tiff is causing the issue.
When running the package manually it will process all files without any issues. my test currently is about 315 files this needs to be able to process at least 1,000 when finished with the ability to send up to 10,000 at one time. The problem is when I set the package to execute using SQL Server Agent it stops at 207 files. The package is deployed to SQL Server 2019 in the SSIS Catalog
What I have tried so far
I started with the script being placed in a SSIS package and deployed to the server and calling the package from a step (works 99.999999% of the time with all packages) tried both 32 and 64 bit runtime. Never any error messages just Unexpected Termination when looking at the execution reports. When clicking in the catalog and executing package it will process all the files. The SQL Server Agent is using a proxy and I also created another proxy account with my admin credentials to test for any issues with the account.
Created another package to call the package and used the Execute Package Task to call the first package, same result 207 files. Changed the execute Process task to an Execute SQL Task and tried the script that is created to manually start a package in the catalog 207 files. Tried executing the script from the command line both through the other SSIS package and the SQL Server Agent directly same results 207 files. If I try any of those methods directly outside SQL Server Agent the process runs no issues.
I converted the script task to a console application and it works processing all the files. When calling the executable file from any method from the SQL Server Agent it once again stops at the 207 files.
I have consulted with the companies DBA and Systems teams and they have not found anything that could be causing this error. There seems to be some type of limit that no matter the method of execution SQL Server Agent will not allow. I have mentioned looking at third-party applications but have been told no.
I have included the code below that I have been able to piece together. I am a SQL developer so C# is outside my knowledge base. Is there a way to optimize the code so it only uses one thread or does a cleanup between each letter. There may be a need for this to create over ten thousand letters at certain times.
Update
I have replaced the code with the new updated code. The email and image creation are all included as this is what the final product must do. When sending the emails there is a primary and secondary email address and depending on what email address is used it will change what the body of the email contains. When looking at the code there is a section of try catch that sends to primary when indicated to and if that fails it send to secondary instead. I am guessing there is a much cleaner way of doing that section but this is my first program as I work in SQL for everything else.
Thank You for all the suggestions and help.
Updated Code
...ANSWER
Answered 2022-Mar-07 at 16:58I have resolved the issue so it meets the needs of my project. There is probably a better solution but this does work. Using the code above I created an executable file and limited the result set to top 100. Created a ssis package with a For Loop that does a record count from the staging table and kicks off the executable file. I performed several tests and was able to exceed the 10,000 limit that was a requirement to the project.
QUESTION
Scenario
I wish to SELECT from a table with simple varchar and integer columns and return a JSON representation of the whole table. This is so that later I can use PhP's curl() to send the 'table' to another server and reconstruct it. I'm using MySQL ver 8.0.28-cll-lve on a remote, shared, server hosted at my ISP. I do not have admin access to the server itself, just all access rights to use and maintain the database.
What I have tried
The code below and in this SQLfiddle in response to this post on Stack Exchange's 'Database Administrators' plus several other posts on SO on the exactly the same topic (I won't list them all as I expect the first reply will tell me this question duplicates them)
Sample code that should work

[{"name_field:", "Mary", "address_field:", "address one", "age_field:", 25},{"name_field:", "Fred", "address_field:", "address two", "age_field:", 35},{"name_field:", "Bill", "address_field:", "address three", "age_field:", 47}]
This is not valid JSON. This is some JSON-like string.

QUESTION
i am in a bit tricky situation. I fetch some price values from a sqlite db and store it in a react state.
the response looks like: [{"price":50},{"price":"49,95"}]
i need to store these values as TEXT insted of INTEGER, because i have a lot of differrent decimal places. also using float in sqlite will not give me exact values, see the problem in this example: https://dba.stackexchange.com/questions/15729/storing-prices-in-sqlite-what-data-type-to-use
So to my main problem: how can i extract and convert the values from the json array to numbers, and sum it up?
...ANSWER
Answered 2022-Feb-23 at 15:31If you don't want to use a library, you could convert all numbers to strings and write your own sum function for strings. This algorithm supports arbitrary long strings containing numbers and returns exact results without rounding errors.
QUESTION
I am trying to execute an SSIS package using a Credential and Proxy - it works fine with a user with a SysAdmin role and we want to avoid using SysAdmin.
I have followed all the steps to create a Credential and Proxy and set up the permissions for the user in msdb and SSISDb tables and in the Security -> logins
I have followed the steps in the below links as a guide:-
- Run an SSIS Package Under a Different Account
- Running a SSIS Package from SQL Server Agent Using a Proxy Account
- SQL Server Agent - Running SSIS Package with Proxy
Proxy -> properties -> Principals
When I run the job I get the below error - looks like a permission issue
Unable to start execution of step 1 (Reason: Could not get proxy data for proxy_id = 198_. The step failed.
What am I missing?
...ANSWER
Answered 2022-Feb-21 at 19:37As you mentioned in the comments, you are using an SQL Server login as a proxy account. While in the Microsoft documentation they mentioned that:
SQL Server Agent proxies use credentials to store information about Windows user accounts. The user-specified in the credential must have "Access this computer from the network" permission (SeNetworkLogonRight) on the computer on which SQL Server is running.
I suggest following one of the following articles to set up an SQL Server agent proxy:

I've gotten locked out of my Oracle APEX workspace. It is hosted locally, not in the Cloud.

This is the code that I am working with at the moment.

Answered 2021-Dec-21 at 02:05You must remember to prepare the query and bind the parameters onto it.
Use the $id
variable to prepare the query with the appropriate ID.
Make sure you authenticate the session before passing the ID to the query, otherwise an attacker can manipulate this data to pull anyone's data they wish.
