Dose oracle.sql.ArrayDescriptor support the user defined type in package?

Not all PL/SQL arrays can be direcly accessed using JDBC. Procedures or Functions that take arrays and are declared inside packages instead of with “CREATE TYPE” can not be called using JDBC. This is a limitation of Oracle.
Approach to solve this issue:
1. Write an additonal wrapper procedure that converts an array created with CREATE TYPE into the format required by your procedure
If you can not change the procedure itself  or it is already used by a large base of existing code you may have to go with option 2 of writing an additional wrapper procedure that takes parameters usable by JDBC:

Original Code: 
Create or Replace Package tms_user_autocode IS
Type DeriveValuesREC IS RECORD (
DefLevelId number(10),
ColumnName VARCHAR2(30),
ValueText tms_dict_contents.term%TYPE,
ClassificationCode VARCHAR2(1));

Type DeriveValuesTAB is TABLE of DeriveValuesREC INDEX BY BINARY_INTEGER;

FUNCTION ClassifyTerm(
pDefDictionaryId     IN  NUMBER
pDefDomainId         IN  NUMBER
pTerm                IN  VARCHAR2
pSourceTermId        IN  NUMBER
pOccurrenceId        IN  NUMBER
pSourceTermAltKey    IN  VARCHAR2

pVTAid               OUT NUMBER

END tms_user_autocode;

ArrayDescriptor.createDescriptor(type, conn);

schema级别对象类型是可以的

只是单独的名字，默认前面是schema,但是不能加package,应该是oracle jdbc里面代码的问题

解决的办法只有对package.type建立一个同义词了（尝试下同义词）

要么你就用schema级别的对象(自定义类型放在包外定义)，jdbc这点不是很好

 

这是一个长久以来的缺陷

To my knowledge, the Oracle JDBC driver does not support using the ArrayDescriptor for array data types (varray or nested table) that are defined inside of a package. The same is true for StructDescriptor as well. If you want to use array and object data types, you must define them outside of a package. Then you'll be able to use the descriptors in your JDBC programs.

 

As far as I know, you can only create an "ArrayDescriptor" and a "StructDescriptor" for database types.

In other words, types that were created using the CREATE TYPE (DDL) statement.

You cannot create an "ArrayDescriptor" or a "StructDescriptor" for types created in PL/SQL packages.
