Command Line Interface

Integrate SnowConvert for Oracle into your CI/CD process with the CLI version of the tool.

This is a deprecated version of the SnowConvert documentation, please visit the official site HERE.

Quick start

To execute a conversion with the SnowConvert CLI you have to have an active license. In the section below we show you how to install a license key.

There are several Command Line Arguments documented below, but the main ones are -i for the input folder and -o for the output folder.

Install a license

To install a license key just execute SnowConvert CLI with the -l argument and the license key.

$: snowct-oracle -l P-ABCD-12345-EFGHI

Check license status

To see a summary with the current license status just execute SnowConvert CLI with just the -l and no other arguments.

$: snowct-oracle -l

Migrate a folder

To migrate a folder just execute SnowConvert CLI program with the -i <INPUT FOLDER> and -o <OUTPUT FOLDER> arguments.

$: snowct-oracle -i ~/Documents/Workspace/Code -o ~/Documents/Workspace/Output

CLI Arguments

Basic Conversion

-i, --input <PATH> (Required)

The path to the folder or file containing the input source code.

-o, --output <PATH> (Required)

The path to the output folder where the converted code and reports will be stored.

-a, --assessmentmode

Flag to indicate whether or not to generate only assessment files. By default, it is set to false.

--snowscript, --disableSnowScript (NO LONGER SUPPORTED)

Flags were used to indicate whether the migration tool should migrate stored procedures to Snowflake Scripting.

As of release 2.0.288. these flags are no longer supported. Please use the following flag instead:

--PLTargetLanguage

-e, --encoding <CODE PAGE>

The encoding code page number is used for parsing the source files. We only accept encodings supported by .NET Core. Here are the ones supported at the moment:

Code Page	Name	Display Name
1200	utf-16	Unicode
1201	unicodeFFFE	Unicode (Big endian)
12000	utf-32	Unicode (UTF-32)
12001	utf-32BE	Unicode (UTF-32 Big endian)
20127	us-ascii	US-ASCII
28591	iso-8859-1	Western European (ISO)
65000	utf-7	Unicode (UTF-7). Not available in .NET 5
65001	utf-8	Unicode (UTF-8). Default encoding

-m, --comments

Flag to indicate if the user wants to comment out objects that have missing dependencies.

Target Language

-t, --PLTargetLanguage <TARGET_LANGUAGE>

The string value specifies the target language to convert Stored procedures and some functions. Currently supported are: SnowScript and JavaScript. The default value is set to SnowScript.

Object Name Customization

-s, --customschema <SCHEMA_NAME>

The string value specifies the custom schema name to apply. If not specified, either PUBLIC or the original database name will be used. Example: DB1.MyCustomSchema.Table1.

If you provide this parameter with a schema name NONE --customschema none, the converted code will keep the original schema defined in the source code.

-d, --database <DB_NAME>

The string value specifies the custom database name to apply. Example: MyCustomDB.PUBLIC.Table1.

--useExistingNameQualification

This flag must be used in conjunction with the -d or -s parameters. When used, it preserves the existing name qualification from the input code when previous parameters are used. Let's take a look at this example where -s newSchema was included:

Input

SELECT * FROM mySchema.myObject;

Default

Using --useExistingNameQualification

The same applies to databases.

License and Help

-l, --license [<LICENSE_KEY>]

Shows the license information. If it's followed by a license key, it will attempt to download and install such a license. For example:

• Showing license status snowct-oracle -l

• Installing a license snowct-oracle -l 12345-ASDFG-67890

--terms

Show license terms information.

--help

Display the help information.

--version

Display the CLI and Code Processor version information.

Other features

--disableSnowScript

Flag to indicate whether SnowConvert should migrate the procedures to Javascript and Python. By default, it is set to false.

--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:

// Oracle 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; 

// Transformation by default

CREATE SCHEMA IF NOT EXISTS emp_mgmt;
...
CREATE OR REPLACE PROCEDURE emp_mgmt.remove_emp (employee_id FLOAT)
...

// Transformation with disablePackagesAsSchemas flag

CREATE OR REPLACE PROCEDURE EMP_MGMT_REMOVE_EMP (employee_id FLOAT)
...

--outerJoinsToOnlyAnsiSyntax

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

--snowscript

Flag to indicate whether SnowConvert should migrate the procedures to Snowscript. By default, it is set to true.

This is a deprecated flag, it will be removed soon.

--disableDateAsTimestamp

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

// Oracle Input
CREATE TABLE DATE_TABLE(
    DATE_COL DATE
);

SELECT SYSDATE FROM DUAL;

// Transformation by default
CREATE OR REPLACE TABLE PUBLIC.DATE_TABLE (
	DATE_COL TIMESTAMP /*** MSC-WARNING - MSCEWI3060 - DEFAULT VALUE FOR SYSDATE IS CURRENT_TIMESTAMP. COLUMN WAS TRANSFORMED TO TIMESTAMP TO PRESERVE INFORMATION. ***/
);

SELECT
	CURRENT_TIMESTAMP
FROM DUAL;

// Transformation with --disableDateAsTimestamp flag
CREATE OR REPLACE TABLE PUBLIC.DATE_TABLE (
	DATE_COL DATE
);

SELECT
	CURRENT_DATE
FROM DUAL;
