|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
A dynamic query may fail at execution time with SQLCODE -901
and reason code "Constant of unsupported type". This can occur
when all the following are true:
- REOPT ONCE is enabled
- The statement includes at least one REOPT supported variable
- The query references an array global variable
For example:
create table t (c int);
create type intarray as int array[2];
create variable arrayvar intarray;
creaet variable intVar int default 2;
set arrayvar[2] = 200;
call set_routine_opts('REOPT ONCE');
create procedure P
language sql
begin atomic
declare stmtText varchar(1024) default 'delete from t where
c = arrayvar[2] or c =intVar'; --
prepare stmt from stmtText; --
execute stmt; --
end;
call P();
SQL0901N The SQL statement or command failed because of a
database system
error. (Reason "Constant of unsupported type".)
