Script Help !!

[vidishaagarwal5]

Hi Team,

I have the below scenario to be implemented help here please.

When a record from the Knowledge Base (kb_knowledge) table is deleted, you want to delete all its attachments to save space.

Hi @vidishaagarwal5 

The Below Simple code will help you !!

// Table: kb_knowledge
// When: before delete
(function executeRule(current, previous) {
var attachmentGR = new GlideRecord('sys_attachment');
attachmentGR.addQuery('table_name', 'kb_knowledge');
attachmentGR.addQuery('table_sys_id', current.sys_id);
attachmentGR.query();

while (attachmentGR.next()) {
attachmentGR.deleteRecord();
}
})(current, previous);

kb_knowledge is the table for knowledge articles not knowledge base.

Try this script in After Delete Business rule on kb_knowledge table:

    var att = new GlideRecord('sys_attachment');
    att.addEncodedQuery('table_sys_id=' + current.sys_id);
    att.query();
    att.deleteMultiple();

Please mark the answer correct/helpful accordingly.

Hi @vidishaagarwal5 ,

1) on  you table you can create the after business rule (delete)

 and paste this script in your business rule

(function executeRule(current, previous /*null when async*/) {

    //thiss  Find all attachments linked to this Knowledge record
    var attachmentGR = new GlideRecord('sys_attachment');
    attachmentGR.addQuery('table_sys_id', current.sys_id);
    attachmentGR.addQuery('table_name', 'kb_knowledge');
    attachmentGR.query();

    //now  Delete each attachment
    while (attachmentGR.next()) {
        attachmentGR.deleteRecord();
    }

})(current, previous);
