SQL, Actions, ESQL Help Please!!!
Hi, I've been poking around but I'm clueless (yes, generally as well as specifically). What am I trying to do: 1) I have a PostgreSQL table with a field called StoryText defined as a Text (virtually unlmited size text data) 2) I wish to update this table with the contents of an XML element ( say StoryTexta lot of text with special characters like ' as well as html code a href=www.clueless.com/IAMwho is this noob?/a/StoryText 3) I've tried ESQL like this: esql:connection esql:poolVSolano/esql:pool esql:execute-query esql:query update Story set Title= 'xsp-request:get-parameter name=Title/', Description= 'xsp-request:get-parameter name=Description/', StoryText= 'xsp-request:get-parameter name=StoryText/' where ContentID = 'xsp-request:get-parameter name=ContentID/' /esql:query /esql:execute-query /esql:connection There have been many attempts :). I HAVE been able to update the table when I use literals and short values for the updates themselves (i.e. ...set Title='This is for noobs'). My questions: 1) should I be using ESQL or Actions? There has been some discussion on the listserve that seems to indicate that Actions are the way to go. 2) do the DatabaseActions work? there seems to have been a lot of confusion about this. 3) Does someone have examples - hopefully of exactly the sort of thing I'm trying to do - Store XML in the db - I'm sure I'm not the first. I am putting together documentation so that when this is all over I can SHARE IT, because no-one should have to live through this again. :) Thanks, Dan - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What am I trying to do: 1) I have a PostgreSQL table with a field called StoryText defined as a Text (virtually unlmited size text data) Texts are a special case that is IMHO not handled. Texts (CLOBs and BLOBs) need to be read and written through a stream. Patches are welcome :-) 2) I wish to update this table with the contents of an XML element ( say StoryTexta lot of text with special characters like ' as well as html code a href=www.clueless.com/IAMwho is this noob?/a/StoryText esql:get-xml is your friend. But it requires well formed XML / XHTML. 3) I've tried ESQL like this: esql:connection esql:poolVSolano/esql:pool esql:execute-query esql:query update Story set Title= 'xsp-request:get-parameter name=Title/', Description= 'xsp-request:get-parameter name=Description/', StoryText= 'xsp-request:get-parameter name=StoryText/' where ContentID = 'xsp-request:get-parameter name=ContentID/' /esql:query /esql:execute-query /esql:connection There have been many attempts :). I HAVE been able to update the table when I use literals and short values for the updates themselves (i.e. ...set Title='This is for noobs'). See above. My questions: 1) should I be using ESQL or Actions? There has been some discussion on the listserve that seems to indicate that Actions are the way to go. In my opinion actions are great for inset / delete / update and esql is great for select. BTW the database actions do support CLOBs. 2) do the DatabaseActions work? there seems to have been a lot of confusion about this. They do work, although I advocate using the new ones form the actions.modular package (CVS-HEAD or CVS-2.0.3 scratchpad). Is there? If you can sumarize it I'd be happy to comment. 3) Does someone have examples - hopefully of exactly the sort of thing I'm trying to do - Store XML in the db - I'm sure I'm not the first. Sorry, not at hand. I am putting together documentation so that when this is all over I can SHARE IT, because no-one should have to live through this again. :) Speaking of documentation, there is some more on datbases and cocoon in CVS-2.0.3 or now live on site. See http://xml.apache.org/cocoon/userdocs/concepts/databases.html for a start. Plus, I'm currently (right now) writing a bit more on the esql logicsheet. Stay tuned. That shouldn't keep you from writing docs, though. We can't get enough of them!
