Resultset
A resultset is the set of records that are retrieved after the execution of an SQL query over an established database connection. It is a fundamental concept in database management systems and plays a crucial role in retrieving, manipulating, and displaying data from a database.

Execution of SQL Query
When an SQL query is executed, it is sent to the database management system (DBMS) for processing. The DBMS analyzes the query, checks for syntax errors, and determines the most efficient way to retrieve the requested data. Once the query is processed, the resultset is generated.

Retrieved Records
The resultset consists of the set of records that match the criteria specified in the SQL query. These records can come from one or multiple tables in the database, depending on the complexity of the query. The resultset can contain zero or more records, depending on whether the query returned any matching data.

Structure of Resultset
The resultset is structured as a table-like structure, with rows and columns. Each row represents a record, and each column represents a specific attribute or field of the records. The columns in the resultset correspond to the columns specified in the SELECT clause of the SQL query.

Manipulating Resultset
Once the resultset is obtained, it can be further manipulated using various operations such as sorting, filtering, grouping, and aggregation. These operations allow for refining the data and extracting specific information from the resultset.

Displaying Resultset
The resultset can be displayed to the user in various formats, such as a table, a list, or a chart, depending on the application or tool used to interact with the database. The user can then analyze, interpret, and utilize the retrieved data for various purposes.

Overall, the resultset is a key component in the retrieval and manipulation of data from a database. It provides the necessary information required to fulfill the user's query and serves as a bridge between the database and the user.
