In a comment you said: <blockquote> <code>clob.getSubString(0, clob.length())</code> throws: <code>java.sql.SQLException: Invalid argument(s) in call at oracle.sql.CLOB.getSubString(CLOB.java:236)</code> while <code>clob.length()</code> returns actual length of my clob </blockquote> The documentation of <a href="http://docs.oracle.com/javase/6/docs/api/java/sql/Clob.html#getSubString%28long,%20int%29" rel="nofollow"><code>getSubString</code></a> states that: <blockquote> pos - the first character of the substring to be extracted. The first character is at position 1. </blockquote> With a simple function to generate and return a CLOB, I can retrieve it over JDBC (<code>ojdbc5</code> or <code>ojdbc6</code>) with no problems, either with <code>getCLOB()</code> or <code>getString()</code>. But if I try to assign the <code>Oracle.sql.CLOB</code> retrieved with <code>getCLOB</code> to a <code>String</code> using <pre><code>String x = getSubString(0, clob.length()); </code></pre> then I also get the <code>Invalid argument(s) in call</code> error. Just changing that to: <pre><code>String x = getSubString(1, clob.length()); </code></pre> works. So it seems to have nothing to do with the temporary allocation in the function, or the CLOB size. I don't understand why you didn't have a problem with smaller CLOBs - maybe your logic just didn't hit this if they were small? In the meantime you've worked around this with <code>clob.getCharacterStream().read()</code>, so this may be a bit irrelevant now.

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.
