SQL Server 2000 contains a powerful set of tools called Data
Transformation Services (DTS) that can help you import, export, and/or
transform data from various sources to single or multiple locations.
DTS was first released with SQL Server 7.0 and has been vastly improved with
the release of SQL Server 2000. Some of the new features include:
- Integration with Windows 2000 security
- The ability of packages to run asynchronously
- HTML Web page source
New FTP, Execute Package, Dynamic Properties, and Message Queue
- The ability to save packages as Visual Basic files
- Enhanced logging and a new multiphase data pump
To get your hands dirty with DTS, I recommend that you begin by using the DTS
wizards. Once you have mastered the wizards, you can move on the DTS Designer
and more advanced topics. The DTS wizards in SQL 2000 provide you with the
quickest way to move or create packages for data transformation. We will start
by looking at the two DTS wizards available within SQL 2000:
- Import/Export Wizard
- Copy Database Wizard
Let’s look at an example of how to use the Import/Export
Wizard. In this example, I will import data from the STEVENW/pubs database into
the SQL2K/DTS database (my test environment contains a default instance of SQL
2000 called STEVENW and a named instance called SQL2K). To export the data to
SQL2K/DTS, I must first create that database. To do this, I open the SQL
Enterprise Manager console, right-click on Databases under STEVENW\SQL2K, and
select New Database (Figure A).
Next, I right-click on the database I want to Import/Export (STEVENW/pubs) and
choose All Tasks | Export Data, as shown in Figure B. This brings up the
DTS Import/Export Wizard Welcome screen.
My next step is to choose a data source that matches the
format of my source data (Figure C). I also need to enter my source
server name (STEVENW), my authentication method, and the database I want to
export. The Advanced button offers more advanced OLE DB options for customizing
Configuring the destination database options is the same as
choosing a data source, but it is important to select the correct destination
server and database. Once I finish configuring the destination options, I click
Next, to bring up the screen shown in Figure D. Here, I can specify a
Table Copy or Query. For this example, I will copy objects and data between SQL
Now that I have chosen my options, I can select the objects
to copy. Figure E shows the options the Import/Export Wizard offers.
In this example, I will accept the defaults. Clicking Next
brings up the Save, Schedule, And Replicate Package screen. I will run the
package immediately and save it to SQL Server (Figure F), although I
also have the option of using replication with this package or scheduling it to
run at a later date.
When I click Next, I advance to a screen where I can
configure a password and give the package a friendly name. I then move on to
the Summary screen to review my information and click Finish. Since I specified
the package to run immediately, it begins to copy the data over to the new
The Copy Database Wizard helps you move or copy a database
to another server. To access this wizard, I choose Tools | Wizards | Management
| Copy Database Wizard. My next step is to choose the source server and
authentication type (similar to what we saw in Figure C). After I make my
selections, I click Next and choose my destination server and authentication
type. Now I can select the databases I want to move or copy (Figure G).
When I click Next, the Database File Location window appears
(Figure H). I can also choose the Modify button to change the databases’
Clicking Next advances me to the Select Related Objects
window (Figure I), where I can specify which SQL Server objects I want
The final two screens let me schedule and review the DTS
package I have created prior to kicking it off. Once everything is complete, I
can view the log details (Figure J).
Working through the Import/Export Wizard and the Copy
Database Wizard is a good way to get familiar with what DTS has to offer. After
mastering the wizards, you can move on to more advanced and custom DTS queries.
