Example of JDBC database accessJAVA's cross-platform processing capabilities (Write Once, Run Anywhere) and excellent image processing capabilities (I believe there is no such language that can surpass JAVA's network processing capabilities) network communication functions, JDBC database access technology, and so on, it is undeniable that the JAVA language is SUN

execute the statement efficiently several times. Common methods Boolean Execute () Executes the SQL statement in this PreparedStatement object, which can be any kind of SQL statement. ResultSet ExecuteQuery () Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query. int executeupdate () Executes the SQL statement in this PreparedStatement object, which must be a SQL data manipulation language (manipulation LANGUAGE,DML) st

We have already seen that JDBC DriverManager can is used to get relational database connections. But if it comes to actual programming, we want more than just connections.Most of the times we is looking for loose coupling for connectivity so, we can switch databases easily, connection POOling for transaction management and distributed systems support. JDBC DataSource is the preferred approach if you be look

He provides a benchmark to build more advanced tools and interfaces so that dev

statements, so you might want to roll back to a particular point in the transaction. The JDBC savepoint helps us create checkpoints (checkpoint) in the transaction so that we can roll back to the specified point. When a transaction commits or the entire transaction is rolled back, any savepoint generated for the transaction is automatically freed and becomes invalid. Rolling a transaction back to a savepoint causes all other savepoint to be automatic

in practical applications, a report with a large amount of data often needs to be taken out of the database at a time when it is presented or exported, and the slow fetch speed of JDBC makes the process extremely inefficient. How to optimize the fetch speed becomes the key to improve the performance of the report. In the run-dry set calculation report, the performance of the JDBC fetch can be improved by pa
