CFMX and SQL Server Data Transformation Services (Part One of Two)
Author: Tedd Van Diest

So you have a bunch of data that you need to migrate from one source to another and preserve the integrity of your data, or you need to import delimited data from a third party that is in the form of "LARGE" flat file(s) without bringing your server to a halt. Well... the answer is Data Transformation Services. If you have not worked with Data Transformation Service yet, I recommend taking a look into, or wait, why don't I just show you.

So what we are going to do today is use coldFusion to generate some data for our text file and then we are going to use coldFusion & DTS to import that data from the text file into SQL Server.

Requirments:
 » coldFusion MX
 » SQL Server 2000
  1. Create a directory under your web root and name it "cfmxDTS".
  2. Copy and paste the code below into .cfm files and name them with the coresponding listing header.
  3. Open up SQL Server and create a new database and name the database "cfmxDTSDB".
  4. Go to, Start > settings > Control Panel > Administrative Tools > Data Sources (ODBC)
    then click on the Sytem DSN tab > Add > Select SQL Server > Finish then type "cfmxDTSDSN" in the Name
    field, select (local) from the server list click Next > check Windows Authentication > Next > check "Change Default Database to:"
    and select "cfmxDTSDB" from the list click Next > Finish > OK > OK > OK.
  5. Open up coldFusion administrator, got to "Data Sources" then type "cfmxDTSDSN" in the datasource field and select ODBC Socket
    from the Driver list and click add, check Trusted Connection then submit.
Now let us move on to the DTS Package steps.
