A table datasheet displays the data in a table format, representing information stored in a database table.

What type of query extract the data and put them into separate table?
An extract, transform, load (ETL) query is typically used to extract data from a source, transform it as needed, and load it into a destination table. This process helps in organizing and transferring data between different systems efficiently.
What is the difference between union and intersect operations in SQL?
In SQL, the UNION operation combines the result sets of two or more queries into a single result set, removing any duplicate rows. The INTERSECT operation returns only the common rows that appear in both result sets of two or more queries.
What is the database term query?
In the context of databases, a query refers to a request for retrieving, updating, or manipulating data stored within a database. It is a way to communicate with the database to perform operations such as data retrieval, insertion, updating, and deletion based on specific criteria. Queries are typically written using query languages like SQL (Structured Query Language) to interact with databases.
What ways can you use to display more fields from a table or query?
To display more fields from a table or query, you can adjust the query to select additional fields by adding them to the SELECT statement. This will allow you to retrieve more specific information from the database. Additionally, you can modify the layout of your display to show additional fields by customizing the user interface or report design to include the desired information.
With SQL how can you delete the records where the FirstName is Peter in the Persons Table?
