General Conversion Settings page

  1. Transform Synonyms: Flag to indicate whether or not Synonyms should be transformed. By default, it’s set to true.

  2. Transform Packages to new Schemas: Flag to indicate whether or not the Packages should be transformed to new Schemas.

    Please check the naming of the procedure enabling and disabling the flag:

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;
Copy
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

  1. Transform Date as Timestamp:

Flag to indicate whether SYSDATE should be transformed into CURRENT_DATE or CURRENT_TIMESTAMP. This will also affect all DATE columns that will be transformed to TIMESTAMP.

CREATE TABLE DATE_TABLE(
    DATE_COL DATE
);

SELECT SYSDATE FROM DUAL;
Copy
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;
Copy
-- 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;
Copy

  1. Transform OUTER JOINS to ANSI Syntax: Flag to indicate whether Outer Joins should be transformed to only ANSI syntax.

  2. Comment objects with missing dependencies: Flag to indicate if the user wants to comment on nodes that have missing dependencies.

  3. Disable EWI comments generation (errors, warnings and issues): Flag to indicate whether EWIs comments (Errors, Warnings, and Issues) will not be generated on the converted code. The default is false.

  4. Set encoding of the input files: The encoding code page number is used for parsing the source files. We only accept encodings supported by .NET Core (https://docs.microsoft.com/en-us/dotnet/api/system.text.encoding?view=net-5.0#list-of-encodings). Here are the ones supported at the moment:

Code PageNameDisplay Name
