execBatch

execBatch is a method commonly used in database programming to execute multiple SQL statements as a single batch operation. This method is part of the Statement interface in JDBC and allows for improved performance when executing multiple similar operations against a database. When using execBatch, SQL statements are added to a batch using the addBatch() method. After all statements have been added, the execBatch() method is called to execute them all together. This approach reduces network round-trips between the application and the database, resulting in significant performance improvements for bulk operations. The method returns an array of update counts, where each element represents the number of rows affected by the corresponding SQL statement in the batch. If any statement fails, the entire batch may be rolled back depending on the error handling configuration. execBatch is particularly useful for operations like bulk inserts, updates, or deletes where multiple similar operations need to be performed. It's commonly used in data migration, ETL processes, and when working with large datasets.
