Character string buffer too small

Posted on 2007-12-06

I have the following code:

g_user_node xmldom.DOMNode;
g_root_element xmldom.DOMElement;
g_item_text xmldom.DOMText;
g_xmlnode xmldom.DOMNode;

cursor c_get_requests is
      select rownum,
      REQUEST_DATE date_created1

I write my xml file using:

for r_get_requests in c_get_requests loop

g_item_element := xmldom.createElement(g_document, 'DATE_CREATED');
g_xmlnode := xmldom.appendChild(g_item_node, xmldom.makeNode(g_item_element));
g_item_text := xmldom.createTextNode(g_document, r_get_requests.date_created1);
g_user_node := xmldom.appendChild(g_xmlnode, xmldom.makeNode(g_item_text));

The above works fine.

NOW I have to output my date_created element in a specific format, but if I change the cursor to:

to_char(REQUEST_DATE,'dd/mm/yyyy hh24:mi:ss') as date_created1,  

I get a ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "TIA.IB02M_VIS", line 284

I dont know why, please help.

what data type and/or format is the field REQUEST_DATE actually?

if it is varchar, you have to put a to_date "first":

to_char(to_date(REQUEST_DATE, 'your_current_format_goes_here'),'dd/mm/yyyy hh24:mi:ss') as date_created1,

I need the XML element in a certain date format: dd/mm/yyyy hh24:mi:ss.

If I dont convert to_char I get 07-DEC-07 which I dont want.

I dont know how else to get this done as The moment I do a to_char, I get the error.

what happens if you run this query directly:

select rownum,
      to_char(REQUEST_DATE,'dd/mm/yyyy hh24:mi:ss') as date_created1

does that work or does it give the same error?

Try to change the cursor declaration like this:

cast( to_char(REQUEST_DATE, 'dd/mm/yyyy hh24:mi:ss') as varchar2(19) ) as date_created1
