Deleting all rows from standard (with loggin) table on IDS 9.40

Hi, how can I delete all rows from standard (with loggin) table on IDS 9.40? - on tuncate table [table_name] server report synstax error (SQL State: 42000, Error Code: -201) - on delete from [table_name] causes long transaction error (SQL State: IX000, Error Code: -458) I use JDBC. There are about 300 000 rows in table. Locking mode is page. Database is non-ansi. Table have some foreing keys and indexes. Thanks helping me, Lukas
