-418 A STATEMENT STRING TO BE PREPARED CONTAINS AN INVALID USE OF PARAMETER MARKERS

Explanation
 The statement cannot be executed because a parameter
marker has been used in an invalid way.
Examples
of places where parameter markers cannot be used:
As an
argument to some built-in functions.
In the
SELECT list of a scalar fullselect that is the sole argument of a scalar function.
In a concatenation operation.
In the string expression of an EXECUTE IMMEDIATE SQL statement.
In a result-expression in any CASE expression
when all the other result-expressions are either
NULL or untyped parameter markers.
In a key-expression of an index definition. 
As an argument to an XMLEXISTS predicate.

System action
 The statement cannot be processed.

Programmer response
 Correct the logic of the application program so that this error does not occur. See the
discussion of the PREPARE statement for information about the proper usage of parameter markers
within SQL statements and for EXECUTE IMMEDIATE SQL statement restrictions. The
PREPARE statement description includes tables that describe contexts where untyped parameter markers
are supported in expressions, predicates, and statements. A CAST specification can be used in some
cases to explicitly assign attributes to a parameter marker.
