SMO Tables DBCC Package Sample



The SMOTablesDBCC sample package illustrates how to enumerate the user tables in the AdventureWorks database by using the Foreach SMO enumerator in a Foreach Loop container. First, a Script task retrieves the schema and table names and puts them into two variables. Next, an Execute SQL task executes a DBCC CHECKCONSTRAINTS command using the two variables.

Note:
To allow the package to run in a 64-bit environment the PreCompile property of the Script task is set to True. If you want the step through the script by using debugging tools, you should set the property to False.

Components in Sample

The following table lists the Integration Services tasks, containers, and connection managers that are used in the sample.

Element Purpose
Foreach Loop The Foreach Loop container, Foreach Loop Container, uses the Foreach SMO enumerator to iterate through the tables in the AdventureWorks database. The Foreach Loop container includes a Script and an Execute SQL task.
Script task The Script task updates the values of variables with the names of the schema and table on each iteration of the loop.
Execute SQL task The Execute SQL task, DBCC CHECK CONSTRAINTS, runs a DBCC command on each iteration of the loop.
OLE DB connection manager The OLE DB connection manager, (local).AdventureWorks, connects to the AdventureWorks database on the local server.
