In Attachment
domein nieuw veld toevoegen Long fileBytesLength
en binnen de mapping sluiting voeg de formule toe voor het berekenen van de lengte van fileBytes
veld.
class Attachment {
String createUserName
String originalFilename
byte[] fileBytes
Long fileBytesLength
Date dateCreated
//Other Properties
static mapping = {
//Other mappings
fileLength formula: "dbms_lob.getlength(fileBytes)"
}
}
En wijzig de zoekopdracht vervolgens in:
def results = Attachment.executeQuery(
'select id, originalFilename, fileBytesLength, dateCreated, createUserName '+
'from Attachment a where a.id not in '+
'(select attachmentId from SpecVersion sv where sv.attachmentId is not null) '+
'and a.dateCreated > sysdate - 30')
