问题 I'm trying to create an OleDb connection to an Excel file that is located on a SharePoint server.

问题 I can use the following syntax in a Jet (mdb) query to select data from another .mdb file: SELECT * FROM [Database=C:\Tempo\AnotherDB.mdb;].MyTable alternatively SELECT * FROM MyTable IN 'C:\Tempo\Another.mdb' I want to extend this to use workgroup security a.k.a. User Level Security (ULS). I know how to specify a userID and password e.g. SELECT * FROM [Database=C:\Tempo\AnotherDB.mdb;UID=Admin;PWD=***;].MyTable but this only works when both mdb's share the same mdw. How would I specify the

Is there any way around this happening? I read somewhere that if you make sure there is a long line

Accessing a JET (.mdb) database in Python

Is there a way to access a JET database from Python? I'm on Linux. All I found was a .mdb viewer in the repositories, but it's very faulty. Thanks MDB Tools is a set of open source libraries and utilities to facilitate exporting data from MS Access databases (mdb files) without using the Microsoft DLLs. Thus non Windows OSs can read the data. Or, to put it another way, they are reverse engineering the layout of the MDB file. Jackcess is a pure Java library for reading from and writing to MS Access databases. It is part of the OpenHMS project from Health Market Science, Inc. . It is not an

How to get id of newly inserted record using Excel VBA?

由 这一生的挚爱 提交于 2019-11-30 07:31:48
问题 Seems a common enough problem this, but most solutions refer to concatenating multiple SQL commands, something which I believe can't be done with ADO/VBA (I'll be glad to be shown wrong in this regard however). I currently insert my new record then run a select query using (I hope) enough fields to guarantee that only the newly inserted record can be returned. My databases are rarely accessed by more than one person at a time (negligible risk of another insert happening between queries) and
