For example, if were looking specifically for{"key": "value"}: select*fromsample_tablewherejson_data@>'{"make": "Toyota"}'; As you might have guessed, we can look for nested JSON objects This will return to us every row containing red, 2-door vehicles" select*fromsample_tablewherejson...
A Java utility is designed to FLATTEN nested JSON objects and even more to UNFLATTEN them back - wnameless/json-flattener
236 json.exception.type_error.313 | invalid value to unflatten | The @ref unflatten function converts an object whose keys are JSON Pointers back into an arbitrary nested JSON value. The JSON Pointers must not overlap, because then the resulting value would not be well defined. 237 json.exce...

Jolt是用Java编写的JSON到JSON转换库,其中指示如何转换的"specification"本身就是一个JSON文档。以下文档中,我统一以 Spec 代替如何转换的"specification"json文档。以LHS(left hand side)代表Spec json的keys,RHS(right hand side)代表Spec json的values。部分示例都是摘取于Jolt源代码注释文档。
For example, myString = new JSONObject().put("JSON", "Hello, World!").toString(); produces the string {"JSON": "Hello, World"}. The texts produced by the toString methods strictly conform to the JSON sysntax rules. The constructors are more forgiving in the texts they will ...
Example 1QueryWhen a query references only one table, the results of the FOR JSON AUTO clause are similar to the results of FOR JSON PATH. In this case, FOR JSON AUTO doesn't create nested objects. The only difference is that FOR JSON AUTO outputs dot-separated aliases (for example, ...
The following example shows how to obtain the home phone number "212 555-1234" from the array built in the previous example: JsonObject home = array.getJsonObject(0); String number = home.getString("number"); JsonArray instances are list objects that provide read-only access to the valu...
