# SQL-029: Count IMAGE_DOCUMENT_TYPE_CODE rows for validation

This statement is a validation query that counts rows in `IMAGE_DOCUMENT_TYPE_CODE` matching a given document type code, category code, and file code combination. It is used by the `clsImageIdx` category/type validation logic (via `clsImageMsgConst.SQL_CAT_TYPE_MISMATCH`) to verify that the combination is valid before saving an image index record.
