Snowflake ROW_NUMBER Analytic

Have you ever needed to find specific rows in a table, such as the first or last claim per family or the first two claims per individual? Use the ROW_NUMBER analytic and find the rows you desire.

Here is the video of 15-tables joining across 15 database systems in a single query. Warning: This video contains what many experts thought was impossible.

Tom Coffing has also led a team of developers for almost 20 years to create the Nexus, which queries, migrates, and joins data across all systems. Amazingly, Nexus migrates between all the databases below with the click of the mouse.


• Excel

• Microsoft Access

• Snowflake

• Redshift

• Synapse

• BigQuery

• Teradata

• Oracle

• SQL Server

• DB2

• Hadoop

• MapR

• Greenplum

• Postgres

• Vertica

• Netezza


• Yellowbrick

• SQLite

The picture above shows Nexus in dark mode migrating Netezza to Snowflake. Some customers are migrating thousands of tables to Snowflake in a single job.

Watch Sherry and Sandy's bold moves to meet their cloud migration deadline.
