This query is used to count drugs (drug_concept_id) across all drug exposure records stratified by drug exposure type (drug_type_concept_id, in CDM V2 drug_exposure_type). The input to the query is a value (or a comma-separated list of values) of a drug_concept_id or a drug_type_concept_id. If the input is omitted, all existing value combinations are summarized.
