What is one of the primary uses of SQL queries when configuring database imports?

• A. Filtering records
• B. Exporting records
• C. Creating new databases
• D. Deleting all records

Answer: (A)

SQL queries are widely utilized in database operations for a variety of purposes, with one of the primary uses being the filtering of records. When configuring database imports, filtering allows users to specify criteria that determine which records are retrieved from the database based on certain conditions. This is crucial for ensuring that only relevant data is imported, enhancing the efficiency and accuracy of the data handling process. For instance, if a user needs to import only customer records from a specific region or with certain purchase histories, SQL queries can be crafted to retrieve only those records that meet the established criteria, effectively filtering out unnecessary data. This targeted approach not only optimizes the import process but also helps in maintaining the integrity of the data being processed. In contrast, alternatives such as exporting records focus on extracting data from a database rather than importing it, while creating new databases involves setting up complete structures for data storage, which is not a focus of import operations. Deleting all records, although a possible action in SQL, would negate the import process itself, as it would remove existing data rather than facilitate the importing of new data. Therefore, filtering records through SQL queries stands out as a fundamental aspect in the context of configuring database imports.
