Nested table issue.

Question

Hi All,
my oracle version is
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
PL/SQL Release 11.1.0.6.0 - Production
CORE     11.1.0.6.0     Production
TNS for 32-bit Windows: Version 11.1.0.6.0 - Production
NLSRTL Version 11.1.0.6.0 - Production
i have created 2 types
lets say Typ_a , Typ_B
this 2 types used in Table_A
create table Table_A
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata,
NESTED TABLE Typ2 STORE AS Typ_Bdata ;
Now i want to use same types in my other tables.
is it possible ??
i got following error
ORA-02320: failure in creating storage table for nested table column Typ1
ORA-22913: must specify table name for nested table column or attribute.

Answer 1

Yes. But you need to change the "segment" name where the data gets stored:
CREATE OR REPLACE TYPE Typ_a AS TABLE OF VARCHAR2(30);
CREATE OR REPLACE TYPE Typ_b AS TABLE OF NUMBER(2);
create table Table_A
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata,
NESTED TABLE Typ2 STORE AS Typ_Bdata;
create table Table_B
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata2,
NESTED TABLE Typ2 STORE AS Typ_Bdata2;
select * from user_segments where segment_name like 'TYP_%';
SEGMENT_NAME                                                                      SEGMENT_TYPE      
TYP_ADATA                                                                         NESTED TABLE      
TYP_ADATA2                                                                        NESTED TABLE      
TYP_BDATA                                                                         NESTED TABLE      
TYP_BDATA2                                                                        NESTED TABLE       -- andy
