    <p>I have a question that makes me crazy on my laptop i have oracle-xe 10.2.0 on ubuntu</p> <p>DB Charset : AMERICAN_AMERICA.AL32UTF8</p> <p>NLS_LANG=AMERICAN_AMERICA.AL32UTF8</p> <pre><code>public static void main(String[] args) throws Exception { // Default locale before overwriting is ru_RU // Locale.setDefault(new Locale("EN")); // Class.forName("oracle.jdbc.driver.OracleDriver"); Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:xe", "test", "test"); try { // @machineName:port:SID, userid, password Statement stmt = conn.createStatement(); try { ResultSet rset = stmt .executeQuery("select * from test"); try { while (rset.next()) System.out.println(rset.getString(1)); // Print col 1 } finally { try { rset.close(); } catch (Exception ignore) { } } } finally { try { stmt.close(); } catch (Exception ignore) { } } } finally { try { conn.close(); } catch (Exception ignore) { } } } </code></pre> <p>If i comment Locale.setDefault i have an ORA-12705: Cannot access NLS data files or invalid environment specified exception (default locale in this case stays ru_RU), but if i set default locale to EN, then everything is all right.</p> <p>What can it mean? Why it is used Locale.getDefault value instead of NLS_LANG, like has written in every article about it?</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
