Excel ODBC Connection to SQL Server table failed.

by lordsmusicalbox - 1/9/07 9:26 AM

Programmers,

Here is the situation: The company I work for has several Excel spreadsheets that are linked to our SQL Server 2000 database via an Access file. All has worked for years until now. When I try to Refresh the spreadsheet for Company3, I get an ODBC Connection Failed Error. Basically, the configuration is as follows:

SQL Server: Database has 3 tables for each company which we will call respectively - Company1, Company2, Company3.

AccessFile.mdb contains linked tables to those tables.

Excel Spreadsheets have a Microsoft Query defined using a Microsoft Access ODBC driver. From there, the linked table
Company3 and its appropriate columns are selected. (it is interesting to note the connection seems to work as it will show the column names when I click (+) to expand the table.) However, as soon I try to run the query, it fails with a ODBC Connection Error.

+++ Note +++ If I select a SQL Server ODBC driver instead of a Microsoft Access ODBC driver in the Microsoft Query Wizard, it will work fine. Data gets refreshed with no problem.

Here is what I have tried and observed:

1. Tested the OBDC connection through the ODBC Datasource Adminstrator. Works fine.

2. In Microsoft Query, selected SQL Server 2000 ODBC Driver.
Refreshed the Excel Spreadsheet. Works as mentioned above.
(The current configuration worked previously using an Access ODBC Driver to the linked SQL table.)

3. Created a new Access database with a link to Company3, thinking maybe the mdb file is corrupt. Still didn't work.

4. I created a new Excel spreadsheet and Microsoft Query to
to the linked table. Same results.

5. Compared the datatypes for Company3 against Company1 and Company2. Looked ok.

6. Copied Company3 into a test table. Tried Refreshing the Excel spreadsheet with Access ODBC Driver and the test table (all records). ODBC Connection failed. I even tried deleting all but one record in the table, but I obtained the same results.

7. Tried SQL Profiler to see if could give any useful information why the conncection failed. All I could find that it was testing the connection, but I could find any information why it failed.


9. Turned on ODBC tracing. Here is a snapshot of the log file:

DIAG [S1000] [Microsoft][ODBC Microsoft Access Driver] ODBC--connection to 'CompanyDatabase' failed. (-2001)

Not sure what is causing this error. I am leaning that it has to so some thing with the table (Company3) itself. Permissions? Any assistance on issue would be greatly appreciated.:-)

By the way, does anyone know why sometimes you get a login dialog when you open a datasource and sometimes not?
