Delete Sample Type

delete_sample_type() deletes an existing sample type in the sample type lookup table

Usage

delete_sample_type(con, sample_type_id)

Arguments

con

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

sample_type_id

A numeric ID for the targeted sample type get_sample_types Note: If an sample type has been associated with a sample, then the database restricts deleting this sample type. You must first update those records with a new sample type before reattempting to delete the sample type. Consider using the update_sample_type_status function if you are wanting to retire an sample type while retaining its value for historic records.
