CREATE TABLE AS SELECT (CTAS) is one of the most important T-SQL features available. It is a fully parallelized operation that creates a new table based on the output of a SELECT statement. CTAS is the simplest and fastest way to create a copy of a table.
For example, use CTAS to:
1. Re-create a table with a different hash distribution column.
2. Re-create a table as replicated.
3. Create a columnstore index on just some of the columns in the table.
4. Query or import external data.
**This syntax is not supported by serverless SQL pool in Azure Synapse Analytics.
