Hi,
I am in the process of reworking a project done in VB 6 / MS Access to a VB.Net / SQL Server 2000 setup.
Currently, as part of our daily process, when the MS Access db is launched it uses the AutoExec feature to go out to a specific directory and import a semicolon-delimited text file.
1) What method would you suggest to take place of this AutoExec feature I am currently using in SQL Server?
2) Any suggestions as to how this data could be combed through and scanned for errors prior to populating in some of my tables I plan to build.
I am a SQL newbie, but from what I have read a stored procedure might accomplish problem 1) and triggers might be good for 2).
I would be most appreciative to hear what methods more experienced db gurus have adopted to import and verify external data.
Thx

Hi,

Without knowing the frequency of importing your options are varied.

A DTS package works very well to import the raw data into a 'staging table'. You can even 'clean' the data using a package.

You can use a scheduled job to import and clean the data.

I would definitely recommend putting the raw data into a separate table before manipulating it. This means you don't have to be too specific with the initial import.

Regards

Graeme

Bulk Insert or DTS packages can achieve this.

Microsoft has articles on line at MSDN.

I'm more inclined to use DTS packages when I need to modify columns in the import process.

Thank You Both,

I will look into DTS. I am going to schedule a job to bring in the table and then perform some checks. After the checks have been made and satisfied I will have a seperate procedure to load specific elements from the base table into a number of other tables I am going to build.
