The error you get is PLS-231, right?
Since you do not show the whole code, I'm reduced to guessing, but this looks like bug 516663 to me, which is described in Metalink Note 1033798.6.
Is function "myfnc" declared in the package spec?
If it is indeed that bug, there are two workarounds: - Declare the function in the package header. - Avoid using the function in an SQL statement.
In your example, you could declare a PL/SQL variable
and use it like this:
helpvar := myfnc(c2);
UPDATE t1 SET c1 = helpvar;
