As an example, below is a transaction. Would it be possible to write a function defining each database/table, so that in the future I could simply plug in the fields and corresponding values and have them go to the correct database as part of that single call?
BEGIN;
INSERT INTO ENTITY.entity (`first_name`, `last_name`, `create_time`, `update_time`, `hashID`)
VALUES ('Lola', 'High', DEFAULT, DEFAULT, DEFAULT);
INSERT INTO NUMID.numID_history (`id_status`, `id`, `criminal_status`, `charge`, `plea`, `sentence`, `create_time`, `update_time`, `hashID`)
VALUES (000, 412056888, 0, NULL, NULL, NULL, DEFAULT, DEFAULT, LAST_INSERT_ID());
INSERT INTO DOB.dob_state (`day`, `month`, `year`, `state_ID`, `stateID_status`, `create_time`, `update_time`, `hashID`)
VALUES (1, 1, 1985, 34506028, 0, DEFAULT, DEFAULT, LAST_INSERT_ID());
COMMIT;
This might entail, for example, a function that inserts a value to a field only IF that field exists. For example, if the field "create_time" exists in all database.tables, then the value would be inserted in each of them. On the other hand, if "last_name" exists in only one of them, then it would be inserted only in that database.table.
I want a function to store which databases have which tables and use a set of fields that entails a union of all databases. Then when I insert values to fields, without me dictating which database gets what, the function should do that automatically.
Could I create such a function? How would I store it?
