RE: Validating JSON Data in a Host Variable

Where did you get " SELECT statement run complete "?
If I run it through ACS or Client Access for windows, it get the return message " Statement ran successfully" (without SELECT).

Jon,

After running the following:

Values(XMLPARSE(Document '<root><Name>xxx</Name><Company
Name="ABC"/></root>'))

The following message is returned:

"SELECT statement run complete."

What makes it a "SELECT statement"?

Kind of contorted, from my perspective.

Thanks Birgitta - easier than I thought but why oh why do they have to
have different syntax for every new feature. So frustrating.

Hi Jon

Is there a similar XML valuation check?
XMLPARSE will convert a "wellformed" XML Document into an internal
representation.
If the document is not wellformed, an error occurs (SQLCODE -20398 /
SQLSTATE 2200M.

Values(XMLPARSE(Document '<root><Name>xxx</Name><Company
Name="ABC"/></root>'));

Is there a similar XML valuation check? Only thing I can find is
the
schema
validation option - <sacrasm> and of course _all_ XML documents
_always_ have schema available! </sacrasm>
