What is the required interpreter for running SQL scripts in SQL Scratchpad?

The correct interpreter for running SQL scripts in SQL Scratchpad is the SQL interpreter, which is identified by the symbol %sql. This interpreter is specifically designed to execute SQL commands and queries, allowing users to interact with databases directly within the Scratchpad environment. By using %sql, users can leverage the syntax and functions of SQL to manipulate and retrieve data efficiently.

In the context of Scratchpad, utilizing the %sql interpreter enables seamless integration with SQL databases, making it straightforward to write and execute standard SQL commands. This interpreter is optimized for handling SQL-specific tasks such as data retrieval, updates, and table management, thereby providing an effective way to work with structured data.

The other interpreters listed serve different programming or scripting purposes: for instance, the %sh interpreter is for shell commands, %spark is used for Apache Spark commands, and %md is related to markdown formatting. Each of these interpreters is distinct in function and is not suited for executing SQL scripts, which solidifies %sql as the definitive choice for that specific task within SQL Scratchpad.
