DB2 SQL XMLSERIALIZE / Select 的 XML 值 *

Question

I would like to output all fields of a SELECT SQL in DB2 as XML. Sorry for using "Select *" here but in this case it makes sense. Have checked XMLSERIALIZE and XMLELEMENT commands but they need a field list. eg

SELECT XMLELEMENT (*) as X from DATA1.CUSTOMERS where CUSTOMERNO='262627'

or

SELECT  XMLSERIALIZE (*) as X from DATA1.CUSTOMERS where CUSTOMERNO='262627'

does not work. Can you help me?

There is no XML publishing function that accepts the wildcard. The easiest way would be to use XMLROW . It accepts a column list or more complex expressions and gives you some options for the final format.

select xmlrow(col1, col2) from mytable

or

select xmlrow(col1, col2 option row "myrowname") from mytable
