I want to read a SQLite db file using Java. Will you please tell me how to read it?
First read these answers
David Crawshaw developed a JAR file (still available on github here but not touched for 10+ years). Taro Saito has a self-contained straightforward JAR file available on github here that includes the JDBC driver and the native runtimes required. Just add this JAR file to your classpath and import java.sql.*
David's test app will create a database file, send some SQL commands to create a table, store some data in the table, and read it back and display on console. It will create the test.db file in the root directory of the project.
public class Test {
public static void main(String[] args) throws Exception {
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
Statement stat = conn.createStatement();
stat.executeUpdate("drop table if exists people;");
stat.executeUpdate("create table people (name, occupation);");
PreparedStatement prep = conn.prepareStatement(
"insert into people values (?, ?);");
prep.setString(1, "Gandhi");
prep.setString(2, "politics");
prep.addBatch();
prep.setString(1, "Turing");
prep.setString(2, "computers");
prep.addBatch();
prep.setString(1, "Wittgenstein");
prep.setString(2, "smartypants");
prep.addBatch();
conn.setAutoCommit(false);
prep.executeBatch();
conn.setAutoCommit(true);
ResultSet rs = stat.executeQuery("select * from people;");
while (rs.next()) {
System.out.println("name = " + rs.getString("name"));
System.out.println("job = " + rs.getString("occupation"));
}
rs.close();
conn.close();
}
}
The Java JDBC driver for SQLLite is on the David Crawshaw site http://www.zentus.com/sqlitejdbc/ Add the jar file to your class path and import java.sql.* and you should be good.
