Command Line Interface

Execute SnowConvert via CLI

Quick start

To execute a conversion with the SnowConvert CLI you have to have an active access code. Currently, the access codes for the CLI are different than the UI, but if you already have an access code for the UI you should be able to reuse the same access code. In the section below we show how to install an access code.

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 an access code

To install an access code just execute SnowConvert CLI program with the install-ac argument and the access code.

$: snowct install-ac --access-code <access-code>

CLI useful commands

  • snowct --help or snowct -h: Will show help.

  • snowct --version or snowct -v: Will show the version of the CLI (and the code processors).

  • snowct install-ac --access-code <access-code>: Will install the corresponding access code provided.

  • snowct install-ac --file <file-with-access-code>: Will install the corresponding access code in the machine (using an access code file).

  • snowct show-ac --platform <platform>: Will show the active access code for a specific platform (Oracle, Teradata, SQL-server, scala, python).

  • snowct {Language} -i ./input -o ./output: Will convert the input code.

    • Supported Languages: Teradata, Oracle, SQL-server.

  • snowct {Language} -i ./input -o ./output --assessment: Will perform an assessment of the input code.

  • You can check the help for a specific command just by using the -h or --help option. For example:

    • snowct install-ac --help

    • snowct show-ac --help

    • snowct teradata --help

Common CLI Arguments

The following arguments can be used in all the languages

-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's set to FALSE.

-t, --PLTargetLanguage <TARGET_LANGUAGE>

String value specifying the target language to convert Stored procedures and Macros. Currently supported are: SnowScript and JavaScript. The default value is set to SnowScript.

-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

-s, --customschema <SCHEMA_NAME>

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

-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:

SELECT * FROM mySchema.myObject;

The same applies to databases.

--rate

The string value specifies the conversion rate mode. Currently supported are: LoC (Lines of Code) and Character. The default value is set to LoC.

-m, --comments

Flag to indicate if the user wants to comment on nodes that have missing dependencies.

--disableEWIsGeneration

Flag to indicate whether EWIs comments (Errors, Warnings, and Issues) will not be generated on the converted code. The default is false.

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 [command] -l

  • Installing a license [command] -l 12345-ASDFG-67890

Additional Parameters

Each tool has its own optional parameters that you can provide in order to customize the conversion/assessment.
