If json_value targets a JSON array, and you specify a SQL collection type (varray or nested table) as the return type, then json_value returns an instance of that collection type. The elements of a targeted JSON array provide the elements of the returned collection-type instance. A scalar...
This function is a string validator of JSON values. It will return the value of 0 if the JSON is invalid and 1 if the JSON string is valid. The function is useful to validate your JSON and if it contains invalid data the function will detect it. Changes in SQL Server 2022 allow yo...
The following example callsOPENJSONand transforms the array of objects that is stored in the@jsonvariable to a rowset that can be queried with a standard Transact-SQLSELECTstatement: SQL DECLARE@jsonNVARCHAR(MAX);SET@json= N'[ {"id": 2, "info": {"name": "John", "surname": "Smith"}...

You can use JSON objects in your databases (do not forget use == and !== operators for deep comparison of objects):alasql> SELECT VALUE {a:'1',b:'2'} {a:1,b:2} alasql> SELECT VALUE {a:'1',b:'2'} == {a:'1',b:'2'} true alasql> SELECT VALUE {a:'1',b:'2'}->b...
The JSON document in the preceding sample query includes an array of objects. The query returns each object as a separate row in the result set. Make sure that you can access this file. If your file is protected with SAS key or custom identity, you ...
The results are formatted as an array of JSON objects. The number of elements in the JSON array is equal to the number of rows in the results of the SELECT statement (before the FOR JSON clause is applied). Each row in the results of the SELECT statement (before the FOR JSON clause ...
