Yes. I don't know where you got the idea that the SET keyword should
appear multiple times, but the SQL92 syntax is perfectly clear that
it appears once:

<update statement: searched> ::=
UPDATE <table name>
SET <set clause list>
[ WHERE <search condition> ]

<set clause list> ::=
<set clause> [ { <comma> <set clause> }... ]

<set clause> ::=
<object column> <equals operator> <update source>

<update source> ::=
<value expression>
| <null specification>
| DEFAULT

<object column> ::= <column name>

How long is the resulting statement? There's an 8K limit on the length
of the query text in 6.5 and older releases (it's gone in current
sources though). If you're not hitting that then I dunno... what error
do you get exactly?
