    <p><strong>My question is:</strong> How do you get around the <code>ORA-01704: string literal too long</code> error when inserting (or doing anything in queries) with <code>CLOB</code>s?</p> <p>I want to have a query like this:</p> <pre><code>INSERT ALL INTO mytable VALUES ('clob1') INTO mytable VALUES ('clob2') --some of these clobs are more than 4000 characters... INTO mytable VALUES ('clob3') SELECT * FROM dual; </code></pre> <p>When I try it with actual values though I get <code>ORA-01704: string literal too long</code> back. This is pretty obvious, but how do I insert clobs (or execute any statement at all with a clob)?</p> <p>I've tried looking at this <a href="https://stackoverflow.com/questions/5549450">question</a>, but I don't think it has what I'm looking for. The clobs I have are in a <code>List&lt;String&gt;</code> and I iterate through them to make the statement. My code as it is follows:</p> <pre><code>private void insertQueries(String tempTableName) throws FileNotFoundException, DataException, SQLException, IOException { String preQuery = " into " + tempTableName + " values ('"; String postQuery = "')" + StringHelper.newline; StringBuilder inserts = new StringBuilder("insert all" + StringHelper.newline); List&lt;String&gt; readQueries = getDomoQueries(); for (String query : readQueries) { inserts.append(preQuery).append(query).append(postQuery); } inserts.append("select * from dual;"); DatabaseController.getInstance().executeQuery(databaseConnectionURL, inserts.toString()); </code></pre> <p>}</p> <pre><code>public ResultSet executeQuery(String connection, String query) throws DataException, SQLException { Connection conn = ConnectionPool.getInstance().get(connection); Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery(query); conn.commit(); ConnectionPool.getInstance().release(conn); return rs; } </code></pre>

    1. COInstead of dynamic SQL and building an insert statement with string literals, have you tried using a `PreparedStatement` and its `setClob()` method?

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.
