This is pretty new to me. I have an Access database that I was to upsize to a SQL server but to keep the Access front end to make this application available remotely. I have imported the data in the SQL database using SSMA which looks to be fine. However, when adding a new record to the Access frontend, the SQL server is not being updated. Am I missing something? I (think I) have linked the tables together but still not joy.
Any help would be great. Thank you
If the data is being stored, but not on the SQL Server then you almost certainly have not linked the tables correctly.
On your Access front end your starting point should be no tables (unless you have some tables deliberately reserved for the front end for some reason). You then link to the back end tables (because you said 'linked the tables together', I suspect you have copies of the tables still in your front end).
During the linking process, Access will confirm if each link is established successfully.
It sounds like you haven't imported the data from MS Access to SQL yet.
Check out the SQL Server Migration Assistant(SSMA) on how to do that.
http://www.microsoft.com/sqlserver/en/us/product-info/migration-tool.aspx#Access.
First you need to migrate the data to SQL and then you link the data in SQL to MS-Access.
Once the tables are linked appropriately it will update in SQL as it is entered in Access.
To link the tables you need to first setup an ODBC and then in access select external data -> import -> more -> ODBC Database and select "Link to the data source by creating linked tables"
Check out this link: http://www.fontstuff.com/ebooks/free/fsLinkingToSQLServer.pdf to make sure you did it right.
I had this problem before.
Create a primary key for every table you want to edit in Access. set identity specification and Identity increment by 1 or ? (you can find this setting in column properties) Make sure data type for primary key is int.
All boolean value fields should have constraint set to 0 and no null values.

We would like to transfer data from a MS Access database to SQLite. Unfortunately, SQlite does not support the whole range of functions provided by Access.
ALTER TABLE Move DROP CONSTRAINT MoveEnum
ALTER TABLE IG_MDB_VERSION DROP COLUMN POOLART
Can anyone give us a replacement in SQLite which realizes the above two SQL statements. Thanks in advance!
If you are now able to link to the sqlite database from Access, and you can edit data with the linked tables from Access?
Then to execute your above sqlLite commands from Access?
Simply create + use what are called pass-though queries from Access. This will allow you to send/execute any valid sqlite commands from Access - including your example(s) in your question.
However before you attempt to use pass-though queries, you want to ensure that you can create linked tables from Access, and those linked tables allow you to edit data (say by clicking on a linked table in Access to sqlite, and that editing etc. works just fine from Access.
I am very new to SQL, MS Access & PostgreSQL. So this might be a very silly question but somehow I can't figure it out. I'm trying to run SQL queries in access and my data is in a PostgreSQL database table which was linked to access by my colleague earlier. When I make this simple query why do I get an error that the table doesn't exist? Is the syntax different for linked database tables? Or is the link not yet established?
You have created a Pass-Through query. This query is executed on the server, not in Access, so you need to use the original table names from the PostgreSQL database.
So it's not FROM public_tb_change but FROM tb_change.
Or maybe FROM public.tb_change, if public isn't the default schema.
I advise to rename your linked tables to the original name (remove public_), that makes things much less confusing. The schema name is automatically added by Access when linking the tables.
I have a database called AQOA_Core with huge amount of data.
I have a newly created database called AQOA_Core1 which is basically empty. I want to write a query to duplicate AQOA_Core to AQOA_Core1 without the data. I guess to be precise I want to create a skeleton of the primary database into the secondary database.
PS: I use Toad for my database operations.
You can use SQL Server Script Wizard for scripting database objects. You can exclude data, and select the database object types you want to include in your script
Please check the SQL Server guide I referenced above,
I hope it helps you
I am new to access. I am using a tool/access database someone built, and it has an ODBC connection to an Oracle SQL database in it.
There are different queries on the side panel, and some of them are delete queries.
If I run these delete queries will they just modify data in my local access database without modifying the data in the Oracle Database?
Yes these will change something in the database whether its linked with another access database table or oracle table and within the database. To review the query you can open the queries in design view and run a normal select query so you can see what the queries are deleting. You can have a normal table image and or globe with a arrow in front pointing towards the table then its linked. A lot of times when I am testing I just run select queries and then I make a copy of what I will be deleting just in case anything goes wrong.
I had a notion to use a database column of type replication ID, but have since changed my approach and want to use this column for another purpose.
However, I'm unable to use SQL to drop the column to remove it from my database.
My SQL is:
ALTER TABLE foo_bar DROP COLUMN theFoo;
However, I get a "syntax error" and I'm assuming this has something to do with this column being a replication ID.
I'd rather not download the file and edit it directly using the MS Access application, but not sure if that's my only recourse.
Thanks so much in advance.

Kris
If you have access to the database in a command shell, Michael Kaplan's Replication System Removal Fields utility should do the trick. However, I've found that in some circumstances, it's unable to do the job. Also note that the utility will only work with a Jet 4 format database (MDB), not ACE format (ACCDB).
If all else fails, you can recreate the table structure and append the existing data to it. That can get messy if you have referential integrity defined, though, but it will get the job done, and likely most of it is scriptable (if not all possible using just DDL).
Here is a link that may help you, I had a similar idea but when browsing the web found this
AccessMonster - Replication-ID-Field-size
EDIT: Well I don't have much time but what I was thinking of first was if you could alter the column to make it different (not a replication ID) and then drop it. (two separate actions). But I have not tested this.
