    <p>Well, you could try something like:</p> <pre><code>with v as ( select 1 col1, '1331882981,ab123456,Some text here which can run multiple lines and have a lot of text... ~1331890329,pqr123223,Some more text...' col2 from dual union all select 2 col1, '133188298777,abc333,Some text here which can run multiple lines and have a lot of text... ~1331890329,pqrs23,Some more text...' col2 from dual ) select distinct col1, regexp_substr(col2, '([0-9]{10},[a-z 0-9]+)', 1, level) split from v connect by level &lt;= REGEXP_COUNT(col2, '([0-9]{10},[a-z0-9]+)') order by col1 ; </code></pre> <p>This gives:</p> <pre><code>1 1331882981,ab123456 1 1331890329,pqr123223 2 1331890329,pqrs23 2 3188298777,abc333 </code></pre> <p><strong>EDIT :</strong> for 10g, <code>REGEXP_COUNT</code> does not exist but you have <a href="http://www.sqlsnippets.com/en/topic-12818.html" rel="nofollow">workarounds</a>. Here I replace the pattern found by something I hope I won't find in the text (here, <code>XYZXYZ</code> but you can choose something much more complex to be confident), do a diff with the same matching but replaced by the empty string, then divide by my pattern length (here, <code>6</code>):</p> <pre><code>with v as ( select 1 col1, '1331882981,ab123456,Some text here which can run multiple lines and have a lot of text... ~1331890329,pqr123223,Some more text...' col2 from dual union all select 2 col1, '133188298777,abc333,Some text here which can run multiple lines and have a lot of text... ~1331890329,pqrs23,Some more text...' col2 from dual ) select distinct col1, regexp_substr(col2, '([0-9]{10},[a-z 0-9]+)', 1, level) split from v connect by level &lt;= (length(REGEXP_REPLACE(col2, '([0-9]{10},[a-z 0-9]+)', 'XYZXYZ')) - length(REGEXP_REPLACE(col2, '([0-9]{10},[a-z 0-9]+)', ''))) / 6 order by col1 ; </code></pre> <p><strong>EDIT 2 :</strong> CLOBs (and LOBs in general) and regexp don't seem to fit well together:</p> <pre><code>ORA-00932: inconsistent datatypes: expected - got CLOB </code></pre> <p>Converting the CLOG to a string (<code>regexp_substr(to_char(col2), ...</code>) seems to fix the issue.</p> <p><strong>EDIT 3 :</strong> CLOBs don't like <code>distinct</code> either, so converting split result to char in an embedded request and then using the <code>distinct</code> on the upper request succeeds ! </p> <pre><code>select distinct col1, split from ( select col1, to_char(regexp_substr(col2, '([0-9]{10},[a-z 0-9]+)', 1, level)) split from temp_epn connect by level &lt;= (length(REGEXP_REPLACE(col2, '([0-9]{10},[a-z 0-9]+)', 'XYZXYZ')) - length(REGEXP_REPLACE(col2, '([0-9]{10},[a-z 0-9]+)', ''))) / 6 order by col1 ); </code></pre>

    2. COHave a look at my edit, it should give you a nice workaround.

    3. COThanks Emmanuel, this gave an error `ORA-00932: inconsistent datatypes: expected - got CLOB` when I changed the "with" to `with t as (select col1, col2 from temp_table)` (col2 has clob)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
