Hi,

I'm trying to execute a xquery statement and I get always errors.
It seems that only the prolog section is giving me errors.
If I want to declare a namespace the xquery processor is coming up with
an "unexpected token" error.
The same error appears if I just set the version.
The xquery statement itself is working without prolog, but I get no
results because of the missing namespace.

db2 => xquery declare default element namespace "http://posample.org";

SQL16002N An XQuery expression has an unexpected token "" following
"http://posample.org"". Expected tokens may include: "<MainModule>".
Error
QName=err:XPST0003. SQLSTATE=10505

Hi,

A question almost identical to this was recently answered on the
developerworks Viper Forum.

http://www-128.ibm.com/developerwork...=118807&cat=19

Basically, a prolog itself is not enough, you need to follow it with
some xquery. The simplest query I used was the expression 3. So I
tried:

db2 -td%
xquery declare default element namespace "http://posample.org"; 3%
and this worked.

Note that since the ; is used to separate the prolog from the xquery
body, I changed the terminator to %.

I hope this helps, post if you still have trouble.

I should have been more clear:

I should have said: you need to follow it with your desired xquery.
Combine the xquery you want to execute and the prolog, and alter the
terminator to have DB2 eat them in one gulp.

The prolog will apply only to the xquery that follows it in the same
DB2 statement.
