How to save JSON to Azure SQL Database in Azure Data Factory

We'll get to know the techniques:

1. Postman tool and the POSTMAN API PLATFORM:

• Postman is a collaborative tool for API development. The following is a basic example of how to use Postman to access

  the YouTube Data API:

  • Create a GET request to the YouTube API URL, for example:GET

    https://www.googleapis.com/youtube/v3/videos
    

  • Add the necessary parameters, such as API key, to authenticate your request.

  • Execute the request and view the response in JSON format.

2. JSON Format, HTTP Response:

• When making an HTTP request to an API, the response is usually in JSON format. JSON Response Example:

  {
    "name": "Example",
    "age": 30,
    "city": "Exemplopolis"
  }
  

3. Get data from the internet (WEB ACTIVITY):

• In Azure Data Factory, the "Web" activity can be used to get data from the internet. Example

  :"

  activities": [
    {
      "name": "WebActivitySample",
      "type": "Web",
      "linkedServiceName": {
        "referenceName": "YourLinkedServiceName",
        "type": "LinkedServiceReference"
      },
      "userProperties": [
        {
          "name": "Url",
          "value": "https://api.example.com/data"
        }
      ]
    }
  ]
  

4. Create and set variable (VARIABLES: IN

• Azure Data Factory, you can create and define variables using the "Set Variable" activity. Example

  :"

  activities": [
    {
      "name": "SetVariableActivity",
      "type": "SetVariable",
      "linkedServiceName": {
        "referenceName": "YourLinkedServiceName",
        "type": "LinkedServiceReference"
      },
      "typeProperties": {
        "variableName": "YourVariableName",
        "value": "ExampleValue"
      }
    }
  ]
  

5. Insert record into Azure SQL Database table (SCRIPT ACTIVITY, CREATE TABLE, INSERT, SQL CODES):

• Use the "Script" activity to run SQL scripts in Azure Data Factory. Example

  :"

  activities": [
    {
      "name": "SqlScriptActivity",
      "type": "SqlScript",
      "linkedServiceName": {
        "referenceName": "YourLinkedServiceName",
        "type": "LinkedServiceReference"
      },
      "typeProperties": {
        "script": "CREATE TABLE ExampleTable (ID INT, Name VARCHAR(255));
  INSERT INTO ExampleTable VALUES (1, 'John'); "
      }
    }
  ]
  

6. Query table with

• To query a SQL table in Azure Data Factory and get data in JSON format, use the "Lookup" or "Copy" activity. Example query:

  SELECT ID, Name FROM ExampleTable FOR JSON AUTO
  

These are basic examples, and the details may vary depending on your specific environment and Azure Data Factory requirements.
