ORA-02449: unique/primary keys in table referenced by foreign keys
I try to drop a tablespace with dependent objects but get below error
SQL> !oerr ora 02449
02449, 00000, "unique/primary keys in table referenced by foreign keys"
// *Cause: An attempt was made to drop a table with unique or
// primary keys referenced by foreign keys in another table.
// *Action: Before performing the above operations the table, drop the
// foreign key constraints in other tables. You can see what
// constraints are referencing a table by issuing the following
// command:
// SELECT * FROM USER_CONSTRAINTS WHERE TABLE_NAME = "tabnam";
Solution:
include cascade constraints option to drop the dependent objects!
