Json auto format

JSON FormatWhen we start working with JSON in SQL Server, we usually first have to retrieve tabular data in this format. Microsoft first implemented a FOR JSON clause in SQL Server 2017 – this clause can be natively used with the SELECT statement, similarly to FOR XML that we use for retrieving data in XML format.FOR JSON allows for two methods to select from:FOR JSON AUTO – output will be formatted according to the SELECT statement structureFOR JSON PATH – output will be formatted according to the user-defined structure, allowing you to use nested objects and propertiesWhichever model you choose, SQL Server will extract relational data in SELECT statements. It will automatically convert the database data types to JSON types and implement character escape rules. Finally, it will format the output according to explicitly or implicitly defined formatting rules.With FOR JSON AUTO, the output format is controlled by the design of the SELECT statement. Thus, using this mode requires a database table or view.USE AdventureWorks2019GOSELECT GETDATE() FOR JSON AUTOWe get the following error message:Msg 13600, Level 16, State 1, Line 4FOR JSON AUTO requires at least one table for generating JSON objects. Use FOR JSON PATH or add a FROM clause with a table name.Now we show how SQL Server automatically generates JSON data. First, it is as output in Management Studio, and then formatted in a text editor:USE AdventureWorks2019GOSELECT TOP(2) JobTitle, FirstName, LastName, City FROM HumanResources.vEmployee FOR JSON AUTO[ { "JobTitle": "Chief Executive Officer", "FirstName": "Ken", "LastName": "Sánchez", "City": "Newport Hills" }, { "JobTitle": "Vice President of Engineering", "FirstName": "Terri", "LastName": "Duffy", "City": "Renton" }]Each row in the original result set is created as a flat property structure. If you compare this to standard XML, you will see much less text. It is because the table names do not appear in the JSON output.The difference in size becomes important when you start to use the ELEMENTS option in XML instead of the default RAW value. To demonstrate this, we use the SELECT statement that compares the data length in bytes of XML and JSON output:USE AdventureWorks2019GOSELECT DATALENGTH( CAST (( SELECT * FROM HumanResources.vEmployee FOR XML AUTO ) AS NVARCHAR(MAX))) AS XML_SIZE_RAW, DATALENGTH( CAST (( SELECT * FROM HumanResources.vEmployee FOR XML AUTO, ELEMENTS ) AS NVARCHAR(MAX))) AS XML_SIZE_ELEMENTS, DATALENGTH( CAST (( SELECT * FROM HumanResources.vEmployee FOR JSON AUTO ) AS NVARCHAR(MAX))) AS JSON_SIZEAs we can see from the query results,

The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.Global Options¶--debug (boolean)Turn on debug logging.--endpoint-url (string)Override command’s default URL with the given URL.--no-verify-ssl (boolean)By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.--no-paginate (boolean)Disable automatic pagination.--output (string)The formatting style for command output.jsontexttableyamlyaml-stream--query (string)A JMESPath query to use in filtering the response data.--profile
