%sResult of ‘%ls’ expression is statically ‘empty’

Error Message:
Msg 2377, Level 16, State 1, Line 4
%sResult of ‘%ls’ expression is statically ‘empty’

Severity level:
16.

Description:
This error message appears when in an Xquery the result of a for expression is statically empty.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
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. The result of a for expression must contain 1 static member at least.

Versions:
This error message was introduced with SQL Server 2005.

Example(s):
DECLARE @xml xml;
SET @xml = ”;
SELECT
    @xml.query(‘for $a in(1, 2, 3), $b in (2, 3, 4), $c in ()
    where
        $a lt $b
    return sum($a + $b)’) as XML;

Remarks:
In the above example we try to specify the for expression $c in (). This expression does not contain any static member and this raises the error.
