%sThe operator “%ls” cannot be applied to “%ls” and “%ls” operands.

Error Message:
Msg 2234, Level 16, State 1, Line 8
%sThe operator “%ls” cannot be applied to “%ls” and “%ls” operands.

Severity level:
16.

Description:
This error message appears when in an XQuery an incompatible operator to the operands.

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. Operators must be applicable to the operands in the XQuery statement.

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″)
    where
        $a lt $b
    return sum($a + $b)’) as XML;

Remarks:
In the above example we try to use the lt operator for operands of type integer and string. This raises the error.
