Hi, SQL Anywhere 11.0.1.2878
We are in the process of creating an interface for a 3rd party system where we need to export an XML file for each new (or modified) record of a particular table. We are hoping to do this by placing a trigger on the table for insert or update actions, which calls the same stored procedure which outputs 6-7 fields of the new/modified row to XML file.
The stored procedure right now, runs a big string (the 'UNLOAD SELECT...' query) with EXECUTE IMMEDIATE. However, when we tried to end the query with "FORMAT XML", the problem we are facing is that our XML file must look like:
<?xml version="1.0" encoding="UTF-16"?>
<Root>
<RecordName>
<Field1>Blablabla</Field1>
<Field2>Blablabla</Field2>
</RecordName>
...
</Root>
and the "Output to C:\test\test.xml FORMAT XML" did not include the first <?xml version="1.0"...> definition line, and neither the <Root> tags.
We have then tried using the XMLGEN function, meaning that our SELECT query which unloads the results looks like:
SELECT XMLGEN( '<?xml version="1.0" encoding="UTF-16" ?> <Root>{$x}</Root>',
(SELECT
Table.Field1 as Field1,
Table.Field2 as Field2,
...
for xml auto, elements) AS x );
This worked well in outputting the <?xml version="1.0" encoding="UTF-16" ?> line at the top of the file, and has put in the <Root> tags as well, however the file exported is an ascii file, and not in true UTF encoding. This is maybe not important as we would probably not work with characters which require UTF, but it would be better to get the UTF encoding.
What would be the best approach to get the UTF-16 (or UTF-8) XML file output out of a stored procedure, that looks like the example above?
Thanks
