SnowConvert AI - Oracle Conversion Settings¶

Object Conversion¶

1. Transform Synonyms: Sinalizador para indicar se os sinônimos devem ou não ser transformados. Por padrão, ele é definido como true.

2. Transform Packages to new Schemas: Sinalizador para indicar se os pacotes devem ou não ser transformados em novos esquemas.

   Verifique a nomenclatura do procedimento de ativação e desativação do sinalizador:

Input

CREATE OR REPLACE PACKAGE emp_mgmt AS
PROCEDURE remove_emp (employee_id NUMBER );
END emp_mgmt;

CREATE OR REPLACE PACKAGE BODY emp_mgmt AS 
PROCEDURE remove_emp (employee_id NUMBER) IS 
   BEGIN 
      DELETE FROM employees 
      WHERE employees.employee_id = remove_emp.employee_id; 
      tot_emps := tot_emps - 1; 
   END; 
END emp_mgmt; 

Output Default

CREATE SCHEMA IF NOT EXISTS emp_mgmt
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
;

CREATE OR REPLACE PROCEDURE emp_mgmt.remove_emp (employee_id NUMBER(38, 18))
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

Output with param disablePackagesAsSchemas

-- Additional Params: --disablePackagesAsSchemas
CREATE OR REPLACE PROCEDURE EMP_MGMT_REMOVE_EMP (employee_id NUMBER(38, 18))
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

3. Transform Date as Timestamp:

Sinalizador para indicar se SYSDATE deve ser transformado em CURRENT_DATE ou CURRENT_TIMESTAMP. Isso também afetará todas as colunas DATE que serão transformadas em TIMESTAMP.

Input

CREATE TABLE DATE_TABLE(
    DATE_COL DATE
);

SELECT SYSDATE FROM DUAL;

Output Default

CREATE OR REPLACE TABLE DATE_TABLE (
        DATE_COL TIMESTAMP /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;

    SELECT
        CURRENT_TIMESTAMP()
    FROM DUAL;

Output with param disableDateAsTimestamp

-- Additional Params: --disableDateAsTimestamp
CREATE OR REPLACE TABLE DATE_TABLE (
        DATE_COL DATE /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;

    SELECT
        CURRENT_DATE()
    FROM DUAL;

4. Transform OUTER JOINS to ANSI Syntax: Sinalizador para indicar se junções externas devem ser transformadas apenas para a sintaxe ANSI.

5. Data Conversion Types: You can upload a JSON file below to define specific data types considering data type origin and column name.

General Result Tab¶

1. Comment objects with missing dependencies: This flag indicates whether the user wants to comment on nodes with missing dependencies.

2. Set encoding of the input files: Check General Conversion Settings for more details.

Description¶

Prepare my code: Flag to indicate whether the input code should be processed before parsing and transformation. This can be useful to improve the parsing process. By default, it’s set to FALSE.

Splits the input code top-level objects into multiple files. The containing folders would be organized as follows:

Copy

└───A new folder named ''[input_folder_name]_Processed''
    └───Top-level object type
        └───Schema name

Example¶

├───in
│       DDL_Packages.sql
│       DDL_Procedures.sql
│       DDL_Tables.sql

├───in_Processed
    ├───package
    │   └───MY_SCHEMA
    │           MY_FIRST_PACKAGE.sql
    │           ANOTHER_PACKAGE.sql
    │
    ├───procedure
    │   └───MY_SCHEMA
    │           A_PROCEDURE.sql
    │           ANOTHER_PROCEDURE.sql
    │           YET_ANOTHER_PROCEDURE.sql
    │
    └───table
        └───MY_SCHEMA
                MY_TABLE.sql
                ADDITIONAL_TABLE.sql
                THIRD_TABLE.sql

Requirements ¶

To identify top-level objects, a tag must be included in a comment before their declaration. Our Extraction scripts generate these tags.

The tag should follow the next format:

<sc-top_level_object_type>top_level_object_name</sc-top_level_object_type>

You can follow the next example:

/* <sc-table> MY_SCHEMA.MY_TABLE</sc-table> */
CREATE TABLE "MY_SCHEMA"."MY_TABLE" (
    "MY_COLUMN" VARCHAR2(128)
) ;
