QUESTION
I have a Perl script which used this connection string to write to an MS Access DB. It worked for Microsoft 365:
...ANSWER
Answered 2021-Jun-12 at 08:50The short issue and story is simply that with Access 2019 (and 2016) CTR (click to run - which is most installations,then installing Access does not expose a registered copy of ACE).

So, you need to install the ACE data engine (not access). Installing ACE from here should do the trick: https://www.microsoft.com/en-us/download/details.aspx?id=54920

I'm building a GUI that allows users to search information in a ms access database (yup. It has to be the ms access) The user has a textfield where he can type his search and the Tableview should update instantly. At the moment the DB disappears whenever you type a letter in the field.
Took me a while to figure out the problem: my SQL statement is simply not right. (Thanks to model.lastError)
The whole function looks like this:

QUESTION
I am trying to change Model names in Abaqus with respect to the values in an array list. At first, I created two array lists and divided them but it is not a good idea as I will have 100 values later on in Beam_h and Beam_w and the values will repeat.. What can I do if I want to have my model names be: model20-10, model30-10, model50-10? Also, the loop I used so far gives me model0, model1, model2. What to write in the loop to get desired model names?
ANSWER
Answered 2021-Jun-07 at 02:01I think, you just need to figure out string concatenation.
You need to check for duplicate model names as well. Because Abaqus replaces the already existing model if you create a model with duplicate name.
To address this issue, you can use dictionary object in following way:
QUESTION
There's an .mdb located on a shared drive in my organization that's password protected and needs to stay password protected. I have the password. I use a local copy for data analysis. The shared drive is very slow for me so I copy it daily using powershell. I need to remove the password manually because the analysis software available to me doesn't support .mdb passwords.
The code below successfully opens the .mdb so I can manually unset the password, but I'd like to automate unsetting the password.
...ANSWER
Answered 2021-Jun-03 at 13:42You can use DAO for that, the DbEngine.Compact method. It's a pain that powershell does not allow naming parameters and skipping the optionals, though, unless you want to do complicated stuff.

QUESTION
Each month I have to create a report from the same set of data. I just finished migrating all of that information into Access and updating my reporting code to read the data from the Access tables, which has been a lifesaver. However, at the end of the report, I need to update one of the tables with this month's "ulr" values. To play it safe, I want the code to never read in this month's ulr values, delete any that exist in the Access table while running, then add this month's ulrs to the table. That way, if I have to run the code more than once, it's always replacing this month's values with the most recent run. All of the values in the table have an "asof" field indicating which reporting month they're from, to make this easier.
I have no problem reading in from the table, and no problem writing new values to it. However, I can't seem to delete records from the table. I would like to delete all records with an "asof" value equal to the variable "reportdate" which is a pandas Timestamp for the report date. This month, it was pd.Timestamp(2021,4,30).
...ANSWER
Answered 2021-Jun-02 at 13:51Delimit the reportdate value with octothorpes (#) so that the Access db engine will recognize it as a Date/Time value:

...ANSWER
Answered 2021-May-28 at 17:24This is because during the initial boot a logging.properties file is used to configure the log manager until the logging subsystem is activated. There are two options.
- You copy an already configured
logging.propertiesandstandalone-ha.xmlover to your image. - In a
RUNcommand in yourDockerfileconfigure logging by starting the server, then executing the CLI script.

QUESTION
I'm trying to export a pandas DataFrame into an MS Access table through pyodbc.
ANSWER
Answered 2021-May-28 at 12:27.to_sql() expects the second argument to be either a SQLAlchemy Connectable object or a DBAPI Connection object. If it is the latter then pandas assumes that it is a SQLite connection.
You need to use the sqlalchemy-access dialect.
(Disclosure: I maintain that dialect.)
