Cannot preview data from Salesforce.com in Data Virtualization

You get an error when you try to preview data from Salesforce.com.

Symptoms

When you try to preview data from the Salesforce.com, you see the following error message:
[DataDirect][SForce JDBC Driver][SForce]MALFORMED_QUERY: OBJECT_NAME: a filter on a COLUMN_NAME column is required

Causes

Certain objects on the Salesforce.com data source require at least one filter for query executions.

Resolving the problem

Use the SQL editor to preview the data. Ensure that you add a filter on a WHERE clause to your query.

For example, you can use the EntityDefinition filter.
