Description

This sample is intended to shown how one could build a developer-centric SAP HANA command line tool, particularly designed to be used when performing local SAP HANA development in non-SAP tooling (like VSCode). It utilizes the default-env.json that is often used in local development for connectivity to a remote SAP HANA DB (although it can of course be used with a local SAP HANA, express edition instance as well). There is no intention to replacing the hdbsql tool as a generic SQL console. Instead this sample will focus on simplifying and grouping common and complex commands that otherwise might a lot of separate scripts.

Introduction Video: https://youtu.be/dvVQfi9Qgog

However the tool isn't limited to only local development. It also works well when developing in the cloud. The hana-cli tool can also run well from a cloud shell in the SAP Business Application Studio, Google Cloud Shell, AWS Cloud9, etc. We can also run against a SAP HANA service for SAP BTP or SAP HANA Cloud instance. This demonstrates that the tool can run just about anywhere you can get a command line that has access to the Node.js Runtime. We can also connect to a remote HANA instance even if it isn't running in the same cloud environment in which we are performing our development tasks.

BTP CLI Installation

The hana-cli tool includes several commands that interact with SAP Business Technology Platform (BTP) services. All BTP-related functionality in this tool relies on the SAP BTP Command Line Interface (btp CLI) being installed and available in your system's PATH.

About the BTP CLI

The btp CLI is SAP's official command-line tool for managing resources and services on the SAP Business Technology Platform. It provides capabilities for managing global accounts, directories, subaccounts, entitlements, service instances, and more. The hana-cli tool wraps and extends many of these capabilities with developer-friendly commands.

Installing the BTP CLI with install-btp.sh

For Linux and macOS users, this repository includes a convenient installation script install-btp.sh that automates the installation of the BTP CLI.

The script performs the following actions:

1. Downloads the latest BTP CLI installer from the SAP Development Tools download page
2. Makes the installer executable and runs it with automatic confirmation
3. Configures shell aliases for easier BTP CLI usage
4. Adds the BTP CLI binary location to your PATH

To use the installation script:

chmod +x scripts/install-btp.sh
./scripts/install-btp.sh

After running the script, you may need to restart your terminal or run source ~/.bashrc to apply the PATH changes.

Note: Windows users should download the BTP CLI from the SAP Development Tools page and follow the platform-specific instructions there.

Verifying the Installation

Once installed, you can verify the BTP CLI is available by running:

btp --version

You can also use the hana-cli tool itself to check your BTP CLI configuration:

hana-cli btp

This will display your current BTP target information including global account, directory, and subaccount if configured.

Security

This application primarily uses the default-env.json that is often used in local development for connectivity to a remote HANA DB (although it can of course be used with a local SAP HANA, express edition instance as well). For more details on how the default-env.json works, see the readme.md of the @sap/xsenv package or the @sap/hdi-deploy package.

Connection Configuration Resolution Order

The tool doesn't simply look for a default-env.json file in the current directory however. There are numerous options and places it will look for the connection parameters. Here is the order in which it checks:

graph TD
    A["Connection Resolution<br/>Started"] --> B{Admin Mode<br/>Enabled?}
    B -->|YES| B1["Look for<br/>default-env-admin.json"]
    B -->|NO| C{.cdsrc-private.json<br/>Found?}
    
    B1 --> B2{Found?}
    B2 -->|YES| Z1["Use Admin Credentials"]
    B2 -->|NO| C
    
    C -->|YES| C1["Use CAP cds bind<br/>Dynamic Lookup"]
    C -->|NO| D{.env File<br/>Found?}
    
    C1 --> Z2["Secure Lookup<br/>from CF/K8s"]
    
    D -->|YES| D1{Contains<br/>VCAP_SERVICES?}
    D1 -->|YES| Z3["Use VCAP Services"]
    D1 -->|NO| E
    D -->|NO| E
    
    E{--conn Parameter<br/>Specified?} -->|YES| E1["Look for specified<br/>connection file"]
    E1 --> E2{Local or<br/>Home Found?}
    E2 -->|YES| Z4["Use Specified File"]
    E2 -->|NO| F
    E -->|NO| F
    
    F["Look for<br/>default-env.json<br/>in current/parent dirs"]
    F --> G{Found?}
    G -->|YES| Z5["Use default-env.json"]
    G -->|NO| H["Last Resort:<br/>Look for default.json<br/>in HOME/.hana-cli/"]
    
    H --> I{Found?}
    I -->|YES| Z6["Use default.json"]
    I -->|NO| Z7["❌ No Connection<br/>Configuration Found"]
    
    style Z1 fill:#51CF66
    style Z2 fill:#51CF66
    style Z3 fill:#51CF66
    style Z4 fill:#51CF66
    style Z5 fill:#51CF66
    style Z6 fill:#51CF66
    style Z7 fill:#FF6B6B

• First we look for the Admin option and use a default-env-admin.json - this overrides all other parameters
• If no admin option or if there was an admin option but no default-env-admin.json could be found in this directory or 5 parent directories, then look for .cdsrc-private.json in this directory or 5 parent directories and use cds bind functionality to lookup the credentials securely. This is the most secure option, but please note: this will make each command take a few seconds longer as credentials are no longer stored locally but looked up from cf or k8s dynamically with each command
• If no .cdsrc-private.json found in this directory or 5 parent directories, then look for a .env file in this directory or up to 5 parent directories
• No .env file found or it doesn't contain a VCAP_SERVICES section, then check to see if the --conn parameter was specified. If so check for that file in the current directory or up to 5 parent directories
• If the file specified via the --conn parameter wasn't found locally then check for it in the ${homedir}/.hana-cli/ folder
• If no specific configuration file was was found then look for a file named default-env.json in the current directory or up to 5 parent directories
• Last resort if nothing has been found up to this point - look for a file named default.json in the ${homedir}/.hana-cli/ folder

Examples

A lot of the functionality of this tool revolves around typical tasks you face while doing HANA database development. For example you might want to get a list of all views in your current schema/container:

C:\github\hana-xsa-opensap-hana7\user_db>hana-cli views
Schema: OPENSAP_HANA_USER, View: *
SCHEMA_NAME        VIEW_NAME                                    VIEW_OID  COMMENTS
-----------------  -------------------------------------------  --------  ------------
OPENSAP_HANA_USER  user.models::USER_DETAILS                    171133    USER_DETAILS
OPENSAP_HANA_USER  user.models::USER_DETAILS/hier/USER_DETAILS  171139    null

Then perhaps you want to inspect a view to see the columns and their data types:

C:\github\hana-xsa-opensap-hana7\user_db>hana-cli view * user.models::USER_DETAILS
Schema: %, View: user.models::USER_DETAILS
{ SCHEMA_NAME: 'OPENSAP_HANA_USER',
  VIEW_NAME: 'user.models::USER_DETAILS',
  VIEW_OID: 171133,
  COMMENTS: 'USER_DETAILS',
  IS_COLUMN_VIEW: 'TRUE',
  VIEW_TYPE: 'CALC',
  HAS_STRUCTURED_PRIVILEGE_CHECK: 'TRUE',
  HAS_PARAMETERS: 'TRUE',
  HAS_CACHE: 'NONE',
  CREATE_TIME: '2019-07-30 13:14:15.594000000' }


SCHEMA_NAME        VIEW_NAME                  VIEW_OID  COLUMN_NAME  POSITION  DATA_TYPE_NAME  OFFSET  LENGTH  SCALE  IS_NULLABLE  DEFAULT_VALUE  CS_DATA_TYPE_NAME  COLUMN_ID  COMMENTS
-----------------  -------------------------  --------  -----------  --------  --------------  ------  ------  -----  -----------  -------------  -----------------  ---------  ---------
OPENSAP_HANA_USER  user.models::USER_DETAILS  171133    EMAIL        1         NVARCHAR        0       255     null   TRUE         null           STRING             171135     Email
OPENSAP_HANA_USER  user.models::USER_DETAILS  171133    FIRSTNAME    2         NVARCHAR        0       40      null   TRUE         null           STRING             171136     FirstName
OPENSAP_HANA_USER  user.models::USER_DETAILS  171133    LASTNAME     3         NVARCHAR        0       40      null   TRUE         null           STRING             171137     LastName
OPENSAP_HANA_USER  user.models::USER_DETAILS  171133    USERID       4         INTEGER         0       10      0      TRUE         null           INT                171138     UserId

But there are multiple output options for inspection. Perhaps you are using Cloud Application Programming Model and need to create a proxy entity in CDS for a view. This tool will read the catalog metadata and convert it to CDS:

C:\github\hana-xsa-opensap-hana7\user_db>hana-cli view OPENSAP_HANA_USER user.models::USER_DETAILS -o cds
Schema: OPENSAP_HANA_USER, View: user.models::USER_DETAILS
@cds.persistence.exists
Entity user_modelsUSER_DETAILS {
 key    "EMAIL": String(255) null  @title: 'EMAIL: Email' ;
key     "FIRSTNAME": String(40) null  @title: 'FIRSTNAME: FirstName' ;
key     "LASTNAME": String(40) null  @title: 'LASTNAME: LastName' ;
key     "USERID": Integer null  @title: 'USERID: UserId' ;
}

Or maybe you are service enabling this view and you want to see it converted to EDMX:

C:\github\hana-xsa-opensap-hana7\user_db>hana-cli view OPENSAP_HANA_USER user.models::USER_DETAILS -o edmx
Schema: OPENSAP_HANA_USER, View: user.models::USER_DETAILS
