![]() ![]() This is how we can use SQLite database in JAVA to perform INSERT, UPDATE, DELETE and SELECT operations based on our requirements. Now, let’s compile and run the program to examine the output like as shown below. If you observe above program we are performing INSERT, UPDATE, DELETE and SELECT operations on table called “ Product”. ( e.getClass().getName() + ": " + e.getMessage() ) out.println(id+ "\t "+name+ " \t "+price+ "\t "+quantity) out.println( "ID\t Name\t\t Price\t Qty ") ResultSet rs = stmt.executeQuery( "SELECT * FROM Product ") Sql= "DELETE FROM Product WHERE p_id=" + id+ " " In SQLite accessing a table locks the entire database so these used ResultSets that were still 'open' were preventing my obtaining write access to a table after I'd read its contents. ![]() Spring Boot supports a few well-known in-memory databases out of the box, but SQLite requires a bit more from us. 2 Answers Sorted by: 6 My problem was that I was relying on the garbage collector to clear up my used ResultSets, I was not explicitly closing them. Sql = "UPDATE Product SET p_name = '"+ name + "',price=" + price + ",quantity=" + quantity + In this quick tutorial, well go through the steps to use an SQLite database in a JPA-enabled Spring Boot application. out.println( "Inserted Successfully!!!") Sql = "INSERT INTO Product (p_name,price,quantity) " + ![]() For a date-only value, use LocalDate with a JDBC driver supporting JDBC 4.2 or later. Sun, Oracle, and the JCP community gave up on these classes. out.println( "Enter a choice: ") Ĭ = DriverManager.getConnection( "jdbc:sqlite:SqliteJavaDB.db") Looking at the bigger picture, another problem is that you are using terrible date-time classes that were years ago supplanted by the modern java.time classes. out.println( "Select DML Operation For Product Table.") Now we will connect to the SQLite database using JAVA if exists otherwise it will create a new database and then connect to it.įollowing is the JAVA program which is used to connect a database if it exists otherwise first it will create a database and then connect to it. Now we need to add downloaded JDBC driver jar file ( sqlite-jdbc-version.jar) to our classpath like shown in our following programs. If JAVA setup available in our PC, now we will install SQLite-JDBC driver for that download latest JDBC driver sqlite-jdbc-version.jar from available list of JDBC drivers. In case if JAVA setup is not available means follow Java Tutorial for JAVA installation. on Windows, Linux, and Mac OS platform.īefore we proceed to interact with SQLite using JAVA language first we need to make sure that JAVA setup available in our PC. Here is a Java program demonstrates how to create an embedded sqlite database as well as the create, read, update and deletion operation using Javas sqlite. This JDBC driver is known as the SQLite-JDBC package which contains both JAVA classes and SQLite libraries to perform different operations like connect to the database, create tables, insert data in tables, etc. We can easily interact with SQLite in JAVA language using a JDBC driver. This isn't a good method, because you loose all data in the database.Here we will learn how to use SQLite in JAVA programming language to connect SQLite database, CREATE Table, INSERT, UPDATE, DELETE and SELECT operations on SQLite tables using JDBC driver with examples. After that the changed tables are created. When the database is next opened onUpgrade is called, which will delete the existing tables. To add a a new column you could simply increase the database version and change the create strings you got to the desired database layout (remove the column you want to delete and add the other). There is a workaround descriped here in the FAQ. ![]()
