 You can find query samples for accessing elements from repeated columns in the [Query Parquet nested types](query-parquet-nested-types.md#access-elements-from-repeated-columns) article.
 
-## Query samples
-
-You can learn more about querying various types of data using the sample queries.
-
-### Tools
-
-The tools you need to issue queries:
-    - Azure Synapse Studio 
-    - Azure Data Studio
-    - SQL Server Management Studio
-
-### Demo setup
-
-Your first step is to **create a database** where you'll execute the queries. Then you'll initialize the objects by executing [setup script](https://github.com/Azure-Samples/Synapse/blob/master/SQL/Samples/LdwSample/SampleDB.sql) on that database. 
-
-This setup script will create the data sources, database scoped credentials, and external file formats that are used to read data in these samples.
-
-> [!NOTE]
-> Databases are only used for viewing metadata, not for actual data.  Write down the database name that you use, you will need it later on.
-
-```sql
-CREATE DATABASE mydbname;
-```
-
-### Provided demo data
-
-Demo data contains the following data sets:
-
-- NYC Taxi - Yellow Taxi Trip Records - part of public NYC data set in CSV and Parquet format
-- Population data set in CSV format
-- Sample Parquet files with nested columns
-- Books in JSON format
