SnowConvert AI - Oracle - Create Type

This is a translation reference to convert Oracle Create Type Statements (UDTs) to snowflake

General Description

One of the most important features the Oracle database engine offers is an Object-Oriented approach. PL/SQL offers capabilities beyond other relational databases in the form of OOP by using Java-like statements in the form of packages, functions, tables and types. This document will cover the last one and how SnowConvert AI solves it, remaining compliant to functionality.

Oracle supports the following specifications:

  • Abstract Data Type (ADT) (including an SQLJ object type).

  • Standalone varying array (varray) type.

  • Standalone nested table type.

  • Incomplete object type.

All this according to the information found in Oracle Create Type Statement Documentation

CREATE [ OR REPLACE ] [ EDITIONABLE | NONEDITIONAL ] TYPE <type name>
[ <type source creation options> ]
[<type definition>]
[ <type properties> ]

Limitations

Snowflake doesn’t support user-defined data types, according to its online documentation Unsupported Data Types, but it supports Semi-structured Data Types, which can be used to mimic the hierarchy-like structure of most User-defined types. For this reason, there are multiple type features that have no workaround.

Following are the User Defined Types features for which NO workaround is proposed:

Subtypes: Type Hierarchy

These statements aren’t supported in Snowflake. SnowConvert AI only recognizes them, but no translation is offered.

CREATE TYPE person_t AS OBJECT (name VARCHAR2(100), ssn NUMBER) 
   NOT FINAL;
/

CREATE TYPE employee_t UNDER person_t 
   (department_id NUMBER, salary NUMBER) 
   NOT FINAL;
/

CREATE TYPE part_time_emp_t UNDER employee_t (num_hrs NUMBER);
/

Type properties

These refer to the options that are normally used when using OOP in PL/SQL: Persistable, Instantiable and Final.

CREATE OR REPLACE TYPE type1 AS OBJECT () NOT FINAL NOT INSTANTIABLE NOT PERSISTABLE;
CREATE OR REPLACE TYPE type2 AS OBJECT () FINAL INSTANTIABLE PERSISTABLE;

Nested Table Type

These statements aren’t supported in Snowflake. SnowConvert AI only recognizes them, but no translation is offered.

CREATE TYPE textdoc_typ AS OBJECT
    ( document_typ      VARCHAR2(32)
    , formatted_doc     BLOB
    ) ;
/

CREATE TYPE textdoc_tab AS TABLE OF textdoc_typ;
/

Type Source Creation Options

These options stand for custom options regarding access and querying the type.

CREATE TYPE type1 FORCE OID 'abc' SHARING = METADATA DEFAULT COLLATION schema1.collation ACCESSIBLE BY (schema1.unitaccesor) AS OBJECT ();
CREATE TYPE type2 FORCE OID 'abc' SHARING = NONE DEFAULT COLLATION collation ACCESSIBLE BY (PROCEDURE unitaccesor) AS OBJECT ();
CREATE TYPE type3 AUTHID CURRENT_USER AS OBJECT ();
CREATE TYPE type4 AUTHID DEFINER AS OBJECT ();

Proposed workarounds

About types definition

For the definition, the proposed workaround is to create semi-structure data type to mimic Oracle’s data type.

About types member function

For the member functions containing logic and DML, the proposed workaround relies on helpers to translate this into stored procedures.

Current SnowConvert AI Support

The next table shows a summary of the current support provided by the SnowConvert AI tool. Please keep in mind that translations may still not be final, and more work may be needed.

Known Issues

1. DML usages for Object Types are not being transformed

As of now, only DDL definitions that use User-Defined Types are being transformed into Variant. This means that any Inserts, Updates or Deletes using User-defined Types are not being transformed and need to be manually transformed. There is no EWI for this but there is a work item to add this corresponding EWI.

2. Create Type creation options are not supported

Currently, there is no known workaround for any of the creation options, for these reasons they are not taken into account when defining the type.

Array Type Definition

This is a translation reference to convert the Array Variant of the Oracle Create Type Statements (UDTs) to Snowflake

Danger

SnowConvert AI only recognizes these definitions and for the moment does not support any translation for them. This page is only used as a future reference for translations.

Note

Some parts in the output code are omitted for clarity reasons.

Description

Array Types define an array structure of a previously existing datatype (including other Custom Types).

For the translation of array types, the type definition is replaced by a Semi-structured Data Type and then it is expanded on any usages across the code. This means taking type’s definition and then expanding it on the original code.

CREATE TYPE <type name>
AS { VARRAY | [VARYING] ARRAY } ( <size limit> ) OF <data type>

Sample Source Patterns

Inserts for the array usage

The next data will be inserted inside the table before querying the select. Please note these Inserts currently need to be manually migrated into Snowflake.

Oracle
INSERT INTO customer_table_demo(customer_table_id, customer_data) VALUES
(1, phone_list_typ_demo('2000-0000', '4000-0000', '0000-0000'));

INSERT INTO customer_table_demo(customer_table_id, customer_data) VALUES
(1, phone_list_typ_demo('8000-2000', '0000-0000', '5000-0000'));
Snowflake
INSERT INTO customer_table_demo(customer_table_id, customer_data)
SELECT 1, ARRAY_CONSTRUCT('2000-0000', '4000-0000', '0000-0000');

INSERT INTO customer_table_demo(customer_table_id, customer_data)
SELECT 1, ARRAY_CONSTRUCT('8000-2000', '0000-0000', '5000-0000');

Array Type usage

Oracle
CREATE TYPE phone_list_typ_demo AS VARRAY(3) OF VARCHAR2(25);

Known Issues

1. Create Type creation options are not supported

Currently, there is no known workaround for any of the creation options, for these reasons they are not taken into account when defining the type.

2. Migrated code output is not functional

The statements are being changed unnecessarily, which makes them no longer be functional on the output code. This will be addressed when a proper transformation for them is in place.

  2. SSC-EWI-0073: Pending Functional Equivalence Review.

Member Function Definitions

This is a translation reference to convert the Member Functions of the Oracle Create Type Statements (UDTs) to Snowflake

Danger

SnowConvert AI still does not recognize type member functions nor type body definitions. This page is only used as a future reference for translation.

Note

Some parts in the output code are omitted for clarity reasons.

Description

Like other Class definitions, Oracle’s TYPE can implement methods to expose behaviors based on its attributes. MEMBER FUCTION will be transformed to Snowflake’s Stored Procedures, to maintain functional equivalence due to limitations.

Since functions are being transformed into procedures, the transformation reference for PL/SQL also applies here.

Nested Table Type Definition

This is a translation reference to convert the Nested Table Variant of the Oracle Create Type Statements (UDTs) to Snowflake

Danger

SnowConvert AI only recognizes these definitions, does not support any translation and there is no known workaround for them.

Description

Nested Table Types define an embedded table structure of a previously existing datatype (including other Custom Types). They can be used as a more powerful version of the Array Type.

Unlike any of the other types, there is still no known workaround or any possible translation for them.

CREATE TYPE <type name> AS TABLE OF <data type>

Object Type Definition

This is a translation reference to convert the Object Variant of the Oracle Create Type Statements (UDTs) to Snowflake

Note

SnowConvert AI supports a translation for Object Type Definitions itself. However, their usages are still a work in progress.

Note

Some parts in the output code are omitted for clarity reasons.

Description

Object Types define a structure of data similar to a record, with the added advantages of the member function definitions. Meaning that their data may be used along some behavior within the type.

For the translation of object types, the type definition is replaced by a Semi-structured Data Type and then it is expanded on any usages across the code. For tables this means replacing the column for a Variant, adding a View so that selects (and also Views) to the original table can still function.

CREATE TYPE <type name> AS OBJECT
( [{<type column definition> | type method definition } , ...]);

Sample Source Patterns

Known Issues

1. Migrated code output is not the same

The view statement is being changed unnecessarily, which makes the table no longer have the same behavior in the output code. There is a work item to fix this issue.

2. DML for User-defined Types is not being transformed

DML that interacts with elements that have User-defined types within them (like a table) are not being transformed. There is a work item to implement this in the future.

3. Create Type creation options are not supported

Currently, there is no known workaround for any of the creation options, for these reasons they are not taken into account when defining the type.

Subtype Definition

This is a translation reference to convert the Subtype Variant of the Oracle Create Type Statements (UDTs) to Snowflake

Danger

Since there are no known workarounds, SnowConvert AI only recognizes these definitions and does not support any translation for them.

Description

Subtypes define a structure of data similar to a record, with the added advantages of the member function definitions. Meaning that their data may be used along some behavior within the type. Unlike Object Types, Subtypes are built as an extension to another existing type.

Regarding subtype definitions, there is still no translation, but there might be a way to reimplement them using Object Type Definitions and then using their respective translation.

CREATE TYPE <type name> UNDER <super type name>
( [{<type column definition> | type method definition } , ...]);
