ResultSet&Statement Interfaces

The ResultSet and Statement interfaces are key components in Java’s JDBC (Java Database Connectivity) API, which allows Java applications to interact with databases.

The Statement interface is used to execute SQL queries against a database. It provides methods to execute different types of SQL statements, such as executeQuery() for retrieving data, executeUpdate() for modifying data, and execute() for executing any SQL statement. The Statement interface is typically used for simple SQL queries that do not require parameters.

On the other hand, the ResultSet interface represents the result set of a query. It provides methods to navigate through the data returned by a query, such as next(), getString(), and getInt(), allowing developers to retrieve data from the result set. The ResultSet is closely tied to the Statement that generated it, as it contains the data returned from the executed SQL statement.

Together, these interfaces facilitate the execution of SQL commands and the retrieval of results in a structured manner.

The idea behind programming to an interface is to base the code primarily on interfaces and only use concrete classes at the time of instantiation. In this context, good code dealing with e.g. Java co...

Don’t Start Your SQL Queries with the ‘Select’ Statement

Towards Data Science

The majority of developers start writing their SQL queries with the ‘SELECT’ clause, then write ‘FROM’, ‘WHERE’, ‘HAVING’….and so on. But this is not the ‘right’ way of writing your SQL queries as…
