Delete Assay

delete_assay.Rd

delete_assay() deletes an existing assay type in the assay lookup table

Usage

delete_assay(con, assay_id)

Arguments

con

A DBI connection object obtained from DBI::dbConnect()

assay_id

A numeric ID for the targeted assay get_assays

Details

Note: If an assay type has been associated with an assay result record, then the database restricts deleting this assay type. You must first update those records with a new assay type before reattempting to delete the assay type. Consider using the update_assay_status function if you are wanting to retire an assay type while retaining its value for historic records.
