This query is used to count the drug type concepts (drug_type_concept_id, in CDM V2 drug_exposure_type) across all drug exposure records. The input to the query is a value (or a comma-separated list of values) of a drug_type_concept_id. If the input is omitted, all possible values are summarized.
Input:

GROUP BY d.drug_type_concept_id
;
Output:
Output field list:
| Field |
Description |
| drug_type_concept_id |

| exposure_occurrence_count |
The number of individual drug exposure occurrences used to construct the drug era. |
