SnowConvert AI - Oracle¶

--disableSynonym¶

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

--disablePackagesAsSchemas¶

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; 

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
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

-- 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
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

--outerJoinsToOnlyAnsiSyntax¶

Flag to indicate whether Outer Joins should be transformed to only ANSI syntax.

--disableDateAsTimestamp¶

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;

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;

-- 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;

--arrange¶

Flag to indicate whether the input code should be processed before parsing and transformation.

Learn more about this step on our Processing the code page.

--dataTypeCustomizationFile¶

The path to a .json file that specifies rules of data type transformation considering data type origin and column name. This feature allows you to customize how data types are transformed during migration, including support for transforming NUMBER columns to DECFLOAT.

When this argument is provided, SnowConvert AI generates a TypeMappings Report that shows all data type transformations applied, making it easy to verify your customization rules were applied correctly.

Navigate to the Data Type Customization documentation to learn more about configuring data type transformation rules.
