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
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).

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.)
QUESTION
Refering to this link C++\SQL ODBC: Get row from table I don't understand the docs and have tried many variations to get something to work but it just outputs complete jibberish. Basically, how can I get data from my Microsoft Access Database into my C++ program. I would eventually want to get the entire table stored as arrays or vectors, that being, lets say there are 5 fields in my table, I want to store (in 5 different arrays or vectors) all the contents to the corresponding fields. But for now, how can I just have something like a table called "Example Table" and within it it has 1 field called "Names" and the type is a string or "short text" as Access calls it. How can I then load that into an array of strings or char*'s to use for my GUI or other parts of the program? Here is my current code:

Answered 2021-Mar-26 at 03:43You need to use SQLGetData, passing SQL_C_WCHAR type, for example, if your column is text. Here's example how to get values of the single text column and put them to vector:
