Connection String error in Azure Data Factory Linked Service - ms-access

Question

I am trying to create a Linked Service to a Access Database in Azure Data Factory. The issue I'm having is that I get this error with my connection string.
It seems to be the backslash in the file location, because it goes away when I erase that. But I need those to write the full file path. It even does this when I try an example connection string from Microsoft or ConnectionStrings.com
the example string = "Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\mydatabase.mdb;"
I'm trying to use the JSON, but even trying to use a key vault secret doesn't work.
{
"name": "MicrosoftAccessLinkedService",
"properties": {
"type": "MicrosoftAccess",
"typeProperties": {
"connectionString": "Driver={Microsoft Access Driver (*.mdb)};Dbq=N:\Inventory Data\WhrsInvLK_22.mdb;",
"authenticationType": "Anonymous"
},
"connectVia": {
"referenceName": "IntegrationRuntime4",
"type": "IntegrationRuntimeReference"
}
}
}

Answer 1

Since the \ is part of the connection string and not used to escape some other character, you need to make sure that the \ character in the connection string itself is escaped.
For example, look at the following demonstration. If you are assigning the same exact string to a variable, it will store the value by placing an additional \ to escape the backslash present in the value.
The output would be as following:
So, you can use the following as the value for your connection string:
Driver={Microsoft Access Driver (*.mdb)};Dbq=N:\\Inventory Data\\WhrsInvLK_22.mdb;
