code snippet - modify filter parameters as needed (STARTSWITH query could also be changed to LIKE)

var sLogSource = 'fixScr:largeOldTables';

gs.print('script start', sLogSource);

var tableNameMatch='cmdb';

var gr = new GlideRecord('sys_dictionary');

gr.addEncodedQuery('internal_type.label=Collection');

gr.addEncodedQuery('nameSTARTSWITH' + tableNameMatch);

gs.print('TOTAL TABLES TARGETTED: ' + gr.getRowCount());

var tableName = gr.name.toString();

var gr1 = new GlideAggregate(tableName);

gr1.addAggregate('COUNT');

var lastUpdated = getLatestRecord(tableName, sLogSource)+"";

if (!gs.nil(lastUpdated)) {

var tableCount = gr1.getAggregate('COUNT');

if (tableCount > sizeCheck) {

var luDate = new GlideDateTime(lastUpdated);

if (luDate < gs.monthsAgoStart(monthsAgoCheck)) {

gs.print('Table: ' + tableName + ' has: ' + tableCount + ' records, [table last updated: ' + lastUpdated + ']', sLogSource);

gs.logError("We've got an error for table: " + gr.name.toString() + "- " + err.toString(), sLogSource);

gs.print('script end', sLogSource);

function getLatestRecord(tableName, logsource) {

var gr = new GlideRecord(tableName);

gr.orderByDesc('sys_updated_on');

if (!gs.nil(gr.sys_updated_on)) {

dReturn = gr.getValue("sys_updated_on");

//gs.log(tableName+'::TABLE LAST UPDATED:' + dReturn,logsource);

}

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g. var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ()) option 3 there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){

Classic UI : var sURL_editparam = gs . action . getGlideURI (). getMap (). get ( ' sysparm_aparameter ' ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); } Portal : var sURL_editparam = $sp . getParameter ( " sysparm_aparameter " ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); }
