Question : Scope of a constraint name? (ORA-02264: name already used by an existing constraint)

Hello experts,
I would like to know the scope of constraint name.  I've read the manual (https://cwisdb.cc.kuleuven.ac.be/ora10doc/server.101/b10759/clauses002.htm#g1053592) but couldnt find the needed info.

In particular, when I run the following sql:
CREATE TABLE myTable02 ( ItemID1 RAW(4) NOT NULL, #more fields here# , CONSTRAINT ItemID_p_k PRIMARY KEY(ItemID1) );
an error is returned: ORA-02264: name already used by an existing constraint

Note that before running the above statement, another sql has been run successfully (only the table name is different):
CREATE TABLE myTable01 ( ItemID1 RAW(4) NOT NULL, #more fields here# , CONSTRAINT ItemID_p_k PRIMARY KEY(ItemID1) );

So the question is: is the scope of the constraint name (ItemID_p_k) bound by the schema or the table? If the scope of constraint is within a table, then why do I have the error?

Thanks,
Do

It is bound by the schema.

You must have different constraint names for every constraint in a schema. It is common practice to include the table name in the constraint name.
