SYS模式Oracle 11g中的NestedTable

Question

 desc sys.dbms_debug_vc2coll
 sys.dbms_debug_vc2coll TABLE OF VARCHAR2(1000)  

I found DBMS_DEBUG_VC2COL1 for table of varchar2.I was searching on the SYS schema if there is defined type for table of numbers?. Any help would be greatly appreciated.

Only reason for using the types in SYS schema is to avoid creating new types in the schema.

Answer 1

The dbms_sql package has a number of predefined collection types , including VARCHAR2_TABLE and NUMBER_TABLE . I'm not sure whether you are exclusively looking for SQL collection types or whether these PL/SQL collection types are sufficient.

Answer 2

有一个预定义的数字类型表：sys.odciNumberList，您可以在处理数字集合时使用它。
