@ComponentProfile(summary="Insert/Update a JSON object into a database",
tag="service,json,jdbc",
since="3.6.5")
public class UpsertJsonObject
extends JdbcMapUpsert
Creates an insert or update statement based on the contents of the JSON object.
{ "firstname":"carol", "lastname":"smith", "dob":"2017-01-03", "id": "1234"}
will effectively execute the following statement INSERT INTO table (firstname,lastname,dob,id) VALUES (?,?,?,?) or
UPDATE table SET firstname=?, lastname=?, dob=? WHERE id = ?; if 1234 already exists as a row.
Note that no parsing/assertion of the column names will be done, so if they are invalid SQL columns then it's going to be
fail. Additionally, nested JSON objects will be rendered as strings before being passed into the appropriate statement; so
{ "firstname":"alice", "lastname":"smith", "address": { "address" : "Buckingham Palace", "postcode":"SW1A 1AA"}} would
still be 3 parameters, the address parameter will be '{ "address" : "Buckingham Palace", "postcode":"SW1A 1AA"}'
In the adapter configuration file this class is aliased as json-jdbc-upsert which is the preferred alternative to the fully qualified classname when building your configuration.
