Have Some Problmes About Atlas

@Chris_Knoll thank you! I find the DDL.But,it seems that some codes don‘t match with my oracle.I just want to modify it,but I don‘t konw whether it will make bad influence.

For example:
①: I set up the ‘results’ schema and run the codes

      CREATE TABLE @results_schema.cohort
(
	COHORT_DEFINITION_ID int NOT NULL,
	SUBJECT_ID bigint NOT NULL,
	cohort_start_date date NOT NULL,
	cohort_end_date date NOT NULL
);

The error is

00903. 00000 -  "invalid table name"
*Cause:    
*Action:

If I delete “@results_schema.”,it runs correctly.Therefore,should I delete it?

②: It seems that identifier should be less than 30 characters in oracle sql developer according to the specify,but the code below:

CONSTRAINT DF_heracles_results_dist_last_update DEFAULT GETDATE()

Obviously,the identifier is more than 30 characters.I do don’t know how to deal with it.

Could you help me once again?
Sincerely.
