 ### Get the metadata for a datasource
 
-Metadata, such as column names, is available either through the [`INFORMATION_SCHEMA`](../querying/sql-metadata-tables.md) table or through `connect.getMetaData()`. The following example uses the `INFORMATION_SCHEMA` table to retrieve and print the list of column names for the `wikipedia` datasource that you loaded during a previous tutorial.

 ### Query data
 
-Now that you know what columns are available, you can start querying the data. The following example queries the datasource named `wikipedia` for the timestamps and comments from Japan. It also sets the [query context parameter](../querying/sql-query-context.md) `sqlTimeZone` . Optionally,  you can also parameterize queries by using [dynamic parameters](#dynamic-parameters).
