I’m trying to load vocabulary files and finding a discrepancy between Athena files and DDL. The Athena download file for drug_strength includes a column called DENOMINATOR_VALUE which is missing from the DDL and also on the wiki description of that table (http://www.ohdsi.org/web/wiki/doku.php?id=documentation:cdm:drug_strength).
CREATE TABLE drug_strength (
drug_concept_id INTEGER NOT NULL,
ingredient_concept_id INTEGER NOT NULL,
amount_value NUMERIC NULL,
amount_unit_concept_id INTEGER NULL,
numerator_value NUMERIC NULL,
numerator_unit_concept_id INTEGER NULL,
denominator_unit_concept_id INTEGER NULL,
valid_start_date DATE NOT NULL,
valid_end_date DATE NOT NULL,
invalid_reason VARCHAR(1) NULL
)
