Avoiding the use of getLast()

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

The getLast() method for an SCFile object will select the last record of the list of results to the currently selected records. However, accessing the last record in a long list of records is not really a good idea. Since Service Manager selects always a block of unique keys, this method requires Service Manager to blockwise step through the complete result list, until it gets to the last one and then fetches its contents.

Unrecommended implementation

The following information is not recommended:

var file = new SCFile("probsummary");

file.doSelect('true');

file.getLast();

Alternatively, you can set the result order by the setOrderBy() method at the time of the select. You can change the sort order that the record you are looking for is no more the last in the list, but the first.

Recommended implementation

The following implementation is recommended:

var file = new SCFile("probsummary");

file.setOrderBy(["number"],[SCFILE_DSC]);

file.doSelect('true');
