    <p>I am trying to update an entry in a table usinig Python cx_oracle. The column is named "template" and it has a data type of CLOB.</p> <p>This is my code:</p> <pre><code>dsn = cx_Oracle.makedsn(hostname, port, sid) orcl = cx_Oracle.connect(username + '/' + password + '@' + dsn) curs = orcl.cursor() sql = "update mytable set template='" + template + "' where id='6';" curs.execute(sql) orcl.close() </code></pre> <p>When I do this, I get an error saying the string literal too long. The template variable contains about 26000 characters. How do I solve this?</p> <p>Edit:</p> <p>I found this: <a href="http://osdir.com/ml/python.db.cx-oracle/2005-04/msg00003.html" rel="nofollow">http://osdir.com/ml/python.db.cx-oracle/2005-04/msg00003.html</a><br> So I tried this:</p> <pre><code>curs.setinputsizes(value = cx_Oracle.CLOB) sql = "update mytable set template='values(:value)' where id='6';" curs.execute(sql, value = template) </code></pre> <p>and I get a "ORA-01036: illegal variable name/number error"</p> <p>Edit2:</p> <p>So this is my code now:</p> <pre><code> curs.setinputsizes(template = cx_Oracle.CLOB) sql = "update mytable set template= :template where id='6';" print sql, template curs.execute(sql, template=template) </code></pre> <p>I get an ORA-00911: invalid character error now.</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.
