Msg 9335, Level 16, State 1, Line 4
%sThe XQuery syntax ‘%ls’ is not supported.
This error message appears when in an XQuery statement the unsupported ‘at’ keyword is found.
The T-SQL statement can be parsed, but causes the error at runtime.
Errors of the Severity level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be run this way. Currently the XQuery standard ‘at’ keyword is not supported.
This error message was introduced with SQL Server 2005.
DECLARE @xml xml;
SET @xml = ”;
@xml.query(‘for $a at $a in(1, 2), $b in(3, 4)
$a < $b
return sum($a + $b)’) as XML;
In the above example we try to use the ‘at’ keyword in an XQuery. This raises the error.
