Sql – Access 2000 connecting to SQL Server 2005

ms-accessms-access-2000sql serversql-server-2005

The company I work for has an old Access 2000 application that was using a SQL Server 2000 back-end. We were tasked with moving the back-end to a SQL Server 2005 database on a new server. Unfortunately, the application was not functioning correctly while trying to do any inserts or updates. My research has found many forum posts that Access 2000 -> SQL 2005 is not supported by Microsoft, but I cannot find any Microsoft documentation to verify that.

Can anyone either link me to some official documentation, or has anyone used this setup and can confirm that this should be working and our problems lie somewhere else?

Not sure if it matters, but the app is an ADP compiled into an ADE.

I've had a similar problem before when using ODBC linked tables to connect to an Sql Server. The solution was to relink the tables and specify the primary key to the table. If Access doesn't know the primary key it cannot perform inserts or updates.

I haven't any experience with ADPs but it could be a similar thing, theres a knowledge base article about it here http://support.microsoft.com/?scid=kb%3Ben-us%3B235267&x=15&y=13

Syntax:

ALTER TABLE {TABLENAME} 
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL} 
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
WITH VALUES

Example:

ALTER TABLE SomeTable
        ADD SomeCol Bit NULL --Or NOT NULL.
 CONSTRAINT D_SomeTable_SomeCol --When Omitted a Default-Constraint Name is autogenerated.
    DEFAULT (0)--Optional Default-Constraint.
WITH VALUES --Add if Column is Nullable and you want the Default Value for Existing Records.

Notes:

Optional Constraint Name:
If you leave out CONSTRAINT D_SomeTable_SomeCol then SQL Server will autogenerate
a Default-Contraint with a funny Name like: DF__SomeTa__SomeC__4FB7FEF6

Optional With-Values Statement:
The WITH VALUES is only needed when your Column is Nullable
and you want the Default Value used for Existing Records.
If your Column is NOT NULL, then it will automatically use the Default Value
for all Existing Records, whether you specify WITH VALUES or not.

How Inserts work with a Default-Constraint:
If you insert a Record into SomeTable and do not Specify SomeCol's value, then it will Default to 0.
If you insert a Record and Specify SomeCol's value as NULL (and your column allows nulls),
then the Default-Constraint will not be used and NULL will be inserted as the Value.

Notes were based on everyone's great feedback below.
