Retrieving All Records from a SQL Table

This challenge focuses on writing a fundamental SQL query to retrieve all data from a specified table. Understanding how to select all records is a cornerstone of database interaction and essential for various data analysis and reporting tasks. Your task is to craft a SQL SELECT statement that accomplishes this.

Problem Description

You are given a SQL table with an unknown schema (column names and data types). Your goal is to write a SQL query that retrieves all columns and all rows from this table. The query should be generic enough to work regardless of the table's structure.

Key Requirements:

• The query must use the SELECT statement.
• The query must retrieve all columns from the table.
• The query must retrieve all rows from the table.
• The query should be compatible with most standard SQL database systems (e.g., MySQL, PostgreSQL, SQL Server, SQLite).

Expected Behavior:

When executed against the table, the query should return a result set containing all data present in the table. The order of rows in the result set is not guaranteed unless an ORDER BY clause is added (which is not required for this challenge).

Edge Cases to Consider:

• Empty Table: The query should still execute successfully and return an empty result set if the table is empty.
• Table Does Not Exist: While the challenge assumes the table exists, consider how your query would behave if the table was not present in the database (this is not a requirement to handle, but good to think about).

Examples

Example 1:

Input: A table named "Customers" with columns "CustomerID", "Name", "City", and "Country".
Output: A result set containing all rows and all columns from the "Customers" table.
Explanation: The query retrieves all data from the "Customers" table, including CustomerID, Name, City, and Country for each customer.

Example 2:

Input: A table named "Products" with columns "ProductID", "ProductName", "Price".
Output: A result set containing all rows and all columns from the "Products" table.
Explanation: The query retrieves all data from the "Products" table, including ProductID, ProductName, and Price for each product.

Example 3:

Input: An empty table named "Orders".
Output: An empty result set.
Explanation: The query executes successfully but returns no rows because the table is empty.

Constraints

• The query must be a single, valid SQL statement.
• The query should not include any WHERE, ORDER BY, GROUP BY, or other filtering/sorting clauses. The goal is to retrieve all data.
• The query must be compatible with standard SQL syntax.
• Assume the table exists and the user has the necessary permissions to query it.

Notes

Think about the most concise and universally accepted way to select all columns in SQL. The asterisk (*) is a wildcard character that can be very helpful here. Remember that the order of rows returned is not specified and may vary depending on the database system.
