QUESTION
I have a form where I want to track asset information for many assets (Assets are already written on the form that the employees fill out)
Assets Hours DSL DEF COOL 10W 30W 40W *Then 12 more fields Asset 1 Asset 2 *Then 55 more assetsThe fields are unbound and the field names are exactly the same but just numbered chronologically (asset1, hours1, dsl1...asset2, hours2, dsl2...etc). I want to know if I can create a loop to save all the rows at the same time by changing the field name.
I'm kind of new to loops, but I wanted to see if it was even possible to change the field name through a loop so I used:

QUESTION
I added two new fields in our table "MTOStudy" & "OtherDesc" as Short Text data types. The other data types within the table are Number and Yes/No values.
However, adding the two columns and updating the table's respective form in Access I can't get to update the table after clicking the button.
Things I've confirmed:
- The button works, using the message box function.
- Variables line up with the table's.
- The code is identical to the working function excluding the addition of the "MTOStudy" and "OtherDesc" variables
- The Error Code I've been seeing is "Error number: 3078 ; The MS Access db engine cannot find the input table or query '128'. Make sure it exists and that its name is spelled correctly."
Debug's line: INSERT INTO tbl_MTO_vs_ETO ([Order], [Line], [MTO], [ETO], [DUP], [MTOStudy], [OtherDesc]) VALUES ( , , -1, 0, 0, "TEST ONE PUMP", "")
Here's the function below:
...ANSWER
Answered 2022-Mar-07 at 19:44If MTOStudy or OtherDesc have quote/apostrophe characters in them (" or ') this will blow up unless you filter these characters out of the input or write yet more code to handle them. You're much better off using a recordset as HackSlash notes above.

QUESTION
I'm using Python (3.8) and SQLAlchemy (1.4.29) to work with an SQL database for a web application project. According to SQLAlchemy's Engine Configuration docs, I can use Python's logging module to control where and how the logs output.
I want the SQLAlchemy engine to output to a file (logs/actions.log
), and stop the logger from outputting to sys.stdout
, so I took this approach:
ANSWER
Answered 2022-Jan-25 at 19:53Try adding logger.propagate = False
- it may be that the events logged to the sqlalchemy
logger are also passed to a StreamHandler
attached to the root logger. You can print logging.getLogger().handlers
to see if that is the case. If not, check if the last two lines add a handler that you're not aware of by printing logger.handlers
after those two calls.

We have an Access Database-Solution with Frontend and Backend Database running for years.
Now within the last two days problems occurred. E.g.
...ANSWER
Answered 2021-Dec-15 at 14:30From Microsoft:
This is due to today’s (Patch Tuesday) update to Office. The problem was introduced by a security fix, so it impacts all active versions of Access. We are working on a fix, and will deliver it as quickly as possible.
The update has only been set to automatically update a very small percentage of users, and it looks like we will be able to pause automatic updates, so it will not propagate.
There will be a page added to the
Fixes or workarounds for recent issues in Access (microsoft.com),
which will then be the place to go for updates.
These are the updates that introduced the problem:

Not sure how to reproduce this as I'm not sure what is causing the issue in the first place, however, I have the currently line of code which writes data to an SQL Server Table.

Answered 2021-Dec-16 at 14:31The issue was I was using an incorrect engine and not replacing the table everytime a new column was found. Changing the engine fixed this and now everything writes to the database as required.
QUESTION
I am trying to duplicate a form from a button using vba. This has worked for years using Allen Browne's "Duplicate the record in form and subform." http://allenbrowne.com/ser-57.html
Now I want to change one of the fields to multivalue. I understand the difficulties with multivalued fields, but this is a 10 year old database and all I need to do is make this field be able to store multiple values, so think this will be easier than creating a new join table and updating everything related.
I am currently getting Invalid use of Property at the rstmv = rstmv.Value line.
I have tried numerous versions and get different errors. I think I should be opening the values of the multi-value field as a separate recordset, updating it then looping through the values but I am getting confused as I am not really sure what I am doing.
Here is the code I I have been using:

I'm working on making a database late bound, so that when the front end is opened, users with different version of MS Office won't have issues. I keep on getting a run time error 438 (Object doesn't support this properts or method) in this code, on the line with For Each tdf In dbs.TableDefs
.
I can't see what is going wrong here. Everything is declared and it should find it. Can someone point out what might be happening?
...ANSWER
Answered 2021-Sep-19 at 11:11You need to actually open a database if you want to use tables.
You have set dbs
to be a database engine, not a database.
If you want it to be the current database, just set it as such, no early binding needed:

...ANSWER
Answered 2021-Aug-31 at 17:30You can skip the DAO part, it's not needed in this case. Macros are project specific, so in order to get them all, you would need to loop through your projects. In my example, i just have one project.
QUESTION
I'm trying to delete an attribute from model object that is created on the go, but there seems to be some problem doing so. So, far I've searched through every place including SQLAlchemy documentation and some of its code to find a potential fix but unable to find one.
Below code works fine on python classes but not with a class inherited from declarative_base
ANSWER
Answered 2021-Jun-10 at 14:11So this was expected, as SQLAlchemy ORM mapped objects don't support this particular state for an attribute, that is, attribute doesn't exist and would raise AttributeError. for an ORM mapped class, a mapped attribute always defaults to None and/or empty collection. there's a little bit of an introduction to this here: https://docs.sqlalchemy.org/en/14/tutorial/orm_data_manipulation.html#instances-of-classes-represent-rows
