SQL
Here we provide an overview of how to perform simple operations in SQL.
This tutorial is only intended to give you an introduction and is in no way a complete tutorial on SQL.
This tutorial is adapted from the [PostgreSQL tutorial](https://www.postgresql.org/docs/current/tutorial-sql-intro.html).  
> DuckDB's SQL dialect closely follows the conventions of the PostgreSQL dialect.
> The few exceptions to this are listed on the [PostgreSQL compatibility page](#docs:sql:dialect:postgresql_compatibility).  
In the examples that follow, we assume that you have installed the DuckDB Command Line Interface (CLI) shell. See the [installation page](https://duckdb.org/docs/installation/) for information on how to install the CLI.
