We are verifying whether the ResultSet object is closed using the isClosed() method. Therefore, soon we close the connection the ResultSet object will be closed. In this we have set the ResultSet holdability to CLOSE_CURSORS_AT_COMMIT. Insert into tutorials_data values(5, 'Cassandra', 'Pruthvi Raj', DATE(' ')) įollowing JDBC program establishes connection with the database, retrieves the contents of the above table into a ResultSet object displays it contents. Insert into tutorials_data values(4, 'Android', 'Sai Ram', DATE('')) Insert into tutorials_data values(3, 'JavaSprings', 'Amit Tiwari', DATE(' ')) ConnectionImpl.getInstance(ConnectionImpl.java:410) at. Insert into tutorials_data values(2, 'JFreeCharts', 'Satish Kumar', DATE(' ')) Now, we will insert 5 records in tutorials_data table using INSERT statements − insert into tutorials_data values(1, 'Java', 'Krishna Kasyap', DATE('')) Let us create a table with name tutorials_data in MySQL database using CREATE statement as shown below − CREATE TABLE tutorials_data ( The isClosed() method of the ResultSet interface is used to determine whether the current ResultSet object is closed. Initially this cursor is positioned before first row (default position). The ResultSet object contains a cursor/pointer which points to the current row. Click on “ Add External Jar” and choose the Jar file from Computer.Whenever we execute SQL statements using the executeQuery() method, it returns a ResultSet object which holds the tabular data returned by the SELECT queries(in general).

Right click on Project in “Package Explorer” and Build path -> Configure Build Path. connection closed.Connection was implicitly closed by the driver. Now it’s time to add JDBC library in our project. Inside “ src” folder in Project on “ Package Explorer” create new Java file and name it properly. For Example: Imagine that your app has 10 database connections and 10 users are active at the same time. If you forget to do so, it will lead your app to connection memory leak. The close () method is used to close the connection. Open Eclipse, Create new Java project from File Menu. By closing the connection, objects of Statement and ResultSet will be closed automatically.

NOTE: For this tutorial and running code successfully I am going to ask you to download the latest Java from here and the Eclipse editor. Im not very acquainted to Java environments, so I dont know exactly whats going on. Im trying to build an application using Play Framework 2.2 and Scala. To know it go to I am going to use “ cdcol” database (it is example database comes with installation) to demonstrate my code. JDBC connection string not working with MySQL on Play Framework. DA: 90 PA: 96 MOZ Rank: 57 Using JDBC to connect to MySQL from Java Program. SQL statements are executed and results are returned within the context of a connection.

Interfaces and classes in JDBC API are written in java. The easiest way to do this is to use Class. Since this tutorial is about connecting to a MySQL database, I am not going to create a new database or that stuff, instead, I am going to use databases that come as an example in the MySQL database. JDBC refers to the Java Database Connectivity.
