+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-# cloud-cap-samples
+# Welcome to cap/samples
 
-This is a monorepository for sample projects on [SAP Cloud Application Programming Model](https://cap.cloud.sap).
+Find here a collection of samples for the [SAP Cloud Application Programming Model](https://cap.cloud.sap) organized in a simplistic [monorepo setup](samples.md#all-in-one-monorepo). → See [**Overview** of contained samples](samples.md)
 
-## Description
+![](https://github.com/SAP-samples/cloud-cap-samples/workflows/CI/badge.svg)
+[![REUSE status](https://api.reuse.software/badge/github.com/SAP-samples/cloud-cap-samples)](https://api.reuse.software/info/github.com/SAP-samples/cloud-cap-samples)
 
-This repository provides a list of samples and reusable packages created based on SAP Cloud Application Programming Model.
-The SAP Cloud Application Programming Model enables you to quickly create business applications by allowing you to focus on your domain logic. It offers a consistent end-to-end programming model that includes languages, libraries and APIs tailored for full-stack development on SAP Cloud Platform.
+### Preliminaries
 
-The samples provided can be run in a local setup on SQLite Database.
+1. Install [**@sap/cds-dk**](https://cap.cloud.sap/docs/get-started/) globally:
 
+   ```sh
+   npm i -g @sap/cds-dk
+   ```
 
-## Requirements
-* [Node.js](https://nodejs.org/en/) v8 or higher
-* [Git](https://git-scm.com)
-* [SQLite DB](https://www.sqlite.org/download.html) (Windows only; pre-installed on Mac/Linux)
+2. _Optional:_ [Use Visual Studio Code](https://cap.cloud.sap/docs/get-started/tools#vscode)
 
-#### Optional (if you want to import the code into an editor)
-* [VS Code](https://code.visualstudio.com)
-* [Add CDS extension to VS](https://cap.cloud.sap/docs/get-started/in-vscode#add-cds-editor)
+### Download
 
-## Download and Installation
+If you've [Git](https://git-scm.com/downloads) installed, clone this repo as shown below, otherwise [download as ZIP file](archive/master.zip).
 
-#### Install `cds` development kit
 ```sh
-# `@sap`-scoped packages are set via .npmrc
-npm install -g @sap/cds-dk
-cds  #> test-run it
+git clone https://github.com/sap-samples/cloud-cap-samples samples
+cd samples
 ```
-Got issues?  Check out the [documentation](https://cap.cloud.sap/docs/get-started/).
 
-#### Clone and build the application
-`git clone https://github.com/SAP-samples/cloud-cap-samples samples && cd samples && npm i`
+### Setup
 
-#### Run the samples
+In the samples folder run:
 
-With that you're ready to run the samples, e.g. start the [_bookshop_](./packages/bookshop) sample as follows:
+```sh
+npm install
+```
 
-`npm run bookshop`
+### Run
 
-## Test
+With that you're ready to run the samples, for example:
 
-For example, try these links in your browser:
-- <http://localhost:4004> to test with generic index page.
-- <http://localhost:4004/fiori.html> to test with Fiori sandbox.
+```sh
+cds watch bookshop
+```
+
+After that open this link in your browser: [http://localhost:4004](http://localhost:4004)
+
+When asked to log in, type `alice` as user and leave the password field blank, which is the [default user](https://cap.cloud.sap/docs/node.js/authentication#mocked).
+
+### Testing
+
+Run the provided tests with [_jest_](http://jestjs.io) or [_mocha_](http://mochajs.org), for example:
+
+```sh
+npx jest
+```
+> While mocha is a bit smaller and faster, jest runs tests in parallel and isolation, which allows to run all tests.
 
 
-## Debug
+### Serve `npm`
 
-For example, in [VS Code](https://code.visualstudio.com) switch to _Debug_ view and launch one of the prepared _cds run_ launch configurations.
+We've included a simple npm registry mock, which allows you to do an `npm install @capire/<package>` locally. Use it as follows:
+
+1. Start the @capire registry:
+```sh
+npm run registry
+```
+> While running this will have `@capire:registry=http://localhost:4444` set with npmrc.
+
+2. Install one of the @capire packages wherever you like, for example:
+
+```sh
+npm add @capire/common @capire/bookshop
+```
 
 
-## Limitations
+## Code Tours
 
-None
+Take one of the [guided tours](.tours) in VS Code through our CAP samples and learn which CAP features are showcased by the different parts of the repository. Just install the [CodeTour extension](https://marketplace.visualstudio.com/items?itemName=vsls-contrib.codetour) for VS Code. We'll add more code tours in the future. Stay tuned!

+# Foreign key constraints on DB
+
+As model we use a simplified version of the bookshop scenario, we work with nodejs runtime.
+
+
+## Preparation
+
+As we want to see the effects of the database constaints, we first need to switch off the integrity checks done by the node runtime. In the `package.json`:
+```json
+"cds": {
+  ...,
+  "features": {
+    "assert_integrity": false
+  }
+}
+```
+
+Then switch on constraint generation. In the `package.json`:
+```json
+"cds": {
+  ...,
+  "cdsc": {
+    "beta": {
+      "foreignKeyConstraints": true
+    }
+  }
+}
+```
+
+## SQLite
+
+In SQLite, FK constraints can only be specified during the creation of a table. They cannot be altered for an existing table. So here we at least don't have issues with existing data.
+
+For SQLite, constraint checks need to be enabled by application at runtime for each db connection with the command
+```sql
+PRAGMA foreign_keys = ON;
+```
+We do this via a custom handler in `admin-service.js`.
+
+Now run the requests in `requests.http` (use `http://localhost:4004` as server URL). They behave as expected.
+
+But the error messages are not providing any details. They say "constraint violation", but they don't say which table/constraint is violated:
+```
+HTTP/1.1 500 Internal Server Error
+...
+{
+  "error": {
+    "code": "SQLITE_CONSTRAINT",
+    "message": "SQLITE_CONSTRAINT: FOREIGN KEY constraint failed in: \nCOMMIT"
+  }
+}
+```
+
+The runtime constraint checks do provide the name of the restricting association (but not the name of the entity where the association lives).
+
+## HANA
+
+Preparation:
+* logon to cf account (e.g. trial)
+* create HANA service instance: `cf create-service hanatrial hdi-shared bookshop-db`
+
+First make the deplyoment without constraints (switch off constraint generation in `package.json`).
+
+* Run `cds build --production`. No constraints are generated.
+* Deploy db model: `cf push -f gen/db`
+* Deploy nodejs app: `cf push -f gen/srv --random-route`. Take note of the app URL.
+
+Run the requests in `request.http` (use the URL from the previous step as server URL, prepend with `https://`).
+Make sure to introduce some data that violates the constraints. No errors are reported - as expected.
+
+Now switch on constraint generation in `package.json`. 
+
+* Run `cds build --production`. The constraints are placed in separate `hdbconstraint` files in `gen\db\src\gen`. They are generated with `VALIDATED ON`.
+* Re-deploy db model: `cf push -f gen/db`. It fails, as the existing data violates the constraints.
+* Check logs: `cf logs bookshop-db-deployer --recent`.
+
+```
+Error: com.sap.hana.di.constraint: Could not create the database object [8250005]
+  at "src/gen/sap.capire.bookshop.Books_author.hdbconstraint" (1:1)
+ Error: com.sap.hana.di.constraint: Database error 7: : feature not supported: referential constraint violated by existing value [8201003]
+   at "src/gen/sap.capire.bookshop.Books_author.hdbconstraint" (1:1)
+```
+You can see which constraint is violated, but there is no info about the offensive entries.
+
+Now use the requests from `request.http` to fix the entries that have been broken above.
+
+* Re-deploy db model: `cf push -f gen/db`. It should succeed.
+
+Again run the requests from `request.http`. This time all changes that would lead to a
+constraint violation fail.
+
+Inserting a book with non-existing author ID or changing a book's author ID to an invalid value yields
+the message
+```
+HTTP/1.1 500 Internal Server Error
+...
+{
+  "error": {
+    "code": "500",
+    "message": "Internal Server Error"
+  }
+}
+```
+When trying to delete a genre that is still referenced in a book we get
+```
+HTTP/1.1 462 status code 462
+...
+{
+  "error": {
+    "code": "462",
+    "message": "failed on update or delete by foreign key constraint violation: TrexColumnUpdate failed on table '21F87859727E470E94917B690908A09D:SAP_CAPIRE_BOOKSHOP_GENRES' with error: DELETE on 21F87859727E470E94917B690908A09D:SAP_CAPIRE_BOOKSHOP_GENRES(ID) failed, because 1 rows with corresponding foreign keys still exist in 21F87859727E470E94917B690908A09D:SAP_CAPIRE_BOOKSHOP_BOOKS(GENRE_ID), rc=1536"
+  }
+}
+```
+
+Note: when using `cdsc` to generate the constraints
+```
+cdsc Q --beta foreignKeyConstraints -d hana -s hdi -o dbstuff db\schema.cds srv\admin-service.cds
+```
+there will be constraints for e.g. `sap_common_Currencies_texts`. This cannot be deplyoed, as the corresponding table is removed from `cds` via the tree-shaking mechanism. These constraints need to be removed manually before deployment.
+
+## Todo
+
+* Provide a way to control parameters `VALIDATED` and `ENFORCED` of the constraints (only interesting for HANA, as in SQLite changing constraints after table generation is not possible).
+* Provide some tool to identify existing entries that violate constraints. We can generate a list of `SELECT` statements that find these entries, but how do we run it and show the results to the user?
+* Can runtimes improve the error messages?
