'JSON' can be used like any other data type. If you insert textual JSON into a JSON type column then the encoding to the binary format happens implicitly - there is no need to call a JSON constructor (although still possible, see below). Any SQL/JSON operator like JSON_VALUE...
That is precisely the point, confirms Mark. Oracle Database can store JSON data in ordinary CLOB columns without a special data type. However, to ensure that users load proper JSON data into theTRANS_MSGcolumn, and not just any bunch of characters, Mark adds a check constraint (TRANS_MSG ...
Oracle Database supports JavaScript Object Notation (JSON) data natively with relational database features, including transactions, indexing, declarative querying, and views.

在PutDatabaseRecord之前,我们想要写入数据到数据库,往往需要使用ConvertJsonToSql+PutSQL组合,尤其是当数据格式不是json的时候还需要先将数据转换为json,而使用ConvertJsonToSql属于一遍连接了目标库,一边要在内存解析一次数据,转成了参数化的SQL,并且参数也是放到FlowFile的属性中,平白无故的这个FlowFile也就更吃内存了...
A string format that emphasizes readability and interoperability at the expense of type preservation. That is, conversion from relaxed format to BSON can lose type information. Both formats conform to theJSON RFCand can be parsed by the various MongoDB drivers and tools. ...
