DB2 FOR LUW / DB2FORLUW / 970 - DB2

You may obtain error SQL0727N after performing CREATE OR REPLACE 
of an existing SQL function.  The following conditions must 
exist for the error to appear; however, the error might not 
appear, even if all of the conditions are met: 
 
- The database contains multiple occurrences of a function F. 
- Each occurrence of F is LANGUAGE SQL. 
- Each occurrence of F is a compiled function.  That is, the 
body the function starts with the BEGIN keyword, and not with 
BEGIN ATOMIC. 
- Each occurrence of F has the same schema, same function name, 
and same number of parameters.  The types of the parameters will 
vary from occurrence to occurrence; meaning, each occurrence of 
the function will have a different signature. 
- One of the occurrences of F has been invalidated. 
 
- CREATE OR REPLACE FUNCTION G, which calls one of the 
occurrences of F that has been invalidated, forcing F to be 
implicitly revalidated.  The CREATE OR REPLACE statement may 
subsequently return with SQL0727N, similar to the following: 
 
SQL0727N  An error occurred during implicit system action type 
"3". 
Information returned for the error includes SQLCODE "-440", 
SQLSTATE "42884" 
and message tokens "G|FUNCTION".  LINE NUMBER=4.  SQLSTATE=56098

Drop and recreate the dependent functions.  Use DROP and CREATE 
FUNCTION for this; do not use CREATE OR REPLACE FUNCTION.  Using 
the error description scenario as a reference, that would mean 
dropping and recreating G, as well as all of the occurrences of 
F.
