You have an error at the end of your append statement:
+';' should be inside the parenthesis for "append". Right now you are trying to concatenate the result of "append" with a string(character)
Correct it to be:

No two SQL dialects are exactly the same for exact transferability. Simply, MariaDB's SQL will not perfectly align to MS Access' SQL similar to running same query from Oracle to Postgres, MySQL to SQL Server, Sybase to DB2... There will need to be some translation.
DATE_FORMATis not an available function in MS Access. Instead use
FORMATwith appropriate format pattern which does not use
More than one
JOINrequire parentheses wrapping in MS Access. However, your mix of
LEFT JOINmay require nested joining.
(Admittedly, this is a frustrating requirement for new Access users to build complex queries with Query Designer and not SQL. I raised this suggested change among others to Access' SQL dialect.)
Fortunately, backticks are supported in MS Access though square brackets,
[...], are the more popular form to escape identifiers with special characters or keywords.
Consider following adjustment:
In Access 2003-2016, I am using CurrentDb.Execute with dbFailonError to run an INSERT statement. The INSERT statement should fail (and it does) because one field has an incorrect value based on a related table with "Enforced Referential Integrity". However, it does not throw an error. I have tried recreating this issue in a new database, and the error works correctly. There is something wrong in the settings with my current database, and I don't want to recreate it from scratch. I have taken everything out of my database except for the problematic piece, and my minimal reproducible example database is at this link.
Here is my code, but the problem is that this code works fine and does throw errors when I create a new database from scratch. It just doesn't work in my current database....

Option Explicit, like Hans said. Always use
You're missing a reference to the Microsoft Office ##.# Access Database Engine object. This is where
dbFailOnError is defined. Because you don't have that reference,
dbFailOnError is not defined. This reference is added to all Access databases by default, and I strongly recommend adding it.
And because you're not using
Option Explicit, VBA doesn't mind that it's undefined and just casts that undefined variable to a zero.
If, for some reason, you don't want to add the reference, use the corresponding value for

You can get the literal valubof any RDFliteral by just casti it to a string with Python’s
str() method so just pass the value as above, not just
r, to the template.
I am using VS 2019 CE v 16.64 with Net Framework 4.8.03761
I have two projects TestSql and Notebook TestSql was built first and the only package installed was System Data SQLite Core
After a few updates to VS 2019 I built Notebook I only installed System Data SQLite Core and WeCantSpell.Hunspell
When I look at the folder packages.config for Notebook I see the following packages installed and wanting Updates
System Numeric Vectors
System Runtime CompileServices Unsafe
Well if I did not install them just Uninstall them That is not working?
The other issue is "If it ain't broke don't fix it" the TestSql project had the packages.config folder at the bottom in Solution Explore I did a Migrate from packages.config to PackageReference
When I saw the phrase Benefits of using PackageReference I should have known this was perhaps a bad idea
Link to Benefits
So the questions are two
How do I get my packages.config folder back where it was? (See Screen Shots)
OR has my OCD clouded my sense of reality that Package References is really better design?
How do I Uninstall the packages I did not install? YES I tried with Manage NuGet Packages

How do I get my packages.config folder back where it was?
If you do not absolutely need
packages.config, then do not go back. The
PackageReference format offers lots of benefits that you do not want to miss in the long run, your link does not lie. It even solves your next problem.
How do I Uninstall the packages I did not install?
You simply don't, because it will break your library. A NuGet package represents a module or set of features consisting of artifacts like assemblies, content files or build scripts. Such a module may have dependencies that it requires to work, for example an SQLite library. Instead of creating one giant archive that contains all assemblies and files that are required, packages specify dependencies to other packages. This way, you can flexibly consolidate and update packages, especially if there are common dependencies of multiple packages, which also prevents having multiple copies of the same assemblies or files in different versions, which can become problematic.
Let's look at the dependencies of the packages that you are using.
- No dependencies
- System.Memory for .NET Framework >= 4.5
[...] the only package installed was System Data SQLite Core
This package does not have any dependencies, that is why there were not additional packages.
[...] I only installed System Data SQLite Core and WeCantSpell.Hunspell
If you look at the list above, the Hunspell package requires
System.Memory, that explains why it is installed, too. Hunspell will not work without it, it depends on it. I hear you ask, where do the other packages come from then? Each package can have dependencies. Consequently a package can depend on a package that depends on other packages that... I think you get the idea. So let's take another look at dependencies for .NET Framework >= 4.6.1.
I think that these are all the dependencies that you were looking for. All these packages will be added to your
packages.config and this is one good reason to migrate to
PackageReference, because it handles transitive package references way better. Suppose you add one package
A with a dependency to package
B and that has a dependency to package
A has a dependency to
C. This is called a transitive dependency.
packages.config will add all packages, while
PackageReferece will only add
A and is smart enough include the other packages, without explicitly adding them. In your example, the project file would only contain the references below.
I have a DataGridView (DGV) that I am adding items to from a SQLite DB MANUALLY
My setting for the Selection Mode have been CellSelect and FullRowSelect may have tried others
The Errors and Issues are varied depending on where the user clicks on the DGV
The code as it is now the Errors only occur when an empty Column under Header PID is selected
And when the Column Header PID is selected See Posted Image
I have included the ERRORS as comments in the code
One of the issues I would like to FIX is to disable all sorting on all Columns
The Data added to the DGV is a primary key which is a Integer PID
And some text which is a NVARCHAR(2048) this text is from a RichTextBox
The two biggest issue to fix is preventing the ERRORS YES those are the Questions

To prevent sorting on columns, which appears to be your main question, do the following:
I am doing a unit test for a program that saves entries in a database "mydatabase". Therefore, I need to restore the db once I test each function so that the other tests are not compromised. I tried to use os.system() to write a mysql command to restore. Below is the relevant part of the program:...
ANSWERAnswered 2020-May-29 at 17:03
Ok, I found out that the problem was that when the user already existed, I did not commit the database, which resulted in the connection not closing, and when I tried to create another one (i.e. used the mysql command), the latter waited forever for the first to end.
To prevent this: either commit or close a connection to the database, or close the cursor before creating another connection to the database (or use the same cursor to restore).
I get a popup box asking for the parameter value for the value of CXIid
Enter Parameter Value
' " & CXIid & " ' but then I get a result of 0 rows being updated. However when I put a value in the where clause or into the Enter Parameter Value prompt I get the correct row updated.
How do I get it to recognize CXIid as a value?...
ANSWERAnswered 2020-Feb-06 at 23:15
You have a few different types of mistakes... the variables cannot be within the quotes, and since the field
CXI_ID is a
String, it does need quotes.
This assumes that the
Consent field is numeric and the combobox is returning a numeric value as well.
