The ServiceNow Glide classes expose JavaScript APIs that enable you to conveniently work with tables using scripts.

Using the Glide APIs, you can perform database operations without writing SQL queries, display UI pages, and define UI actions. The following tables provide brief descriptions of the Glide classes and links to detailed information.

Server-side Glide classes

Class Description
GlideRecord Use this class for database operations instead of writing SQL queries. GlideRecord is a special Java class that can be used in JavaScript exactly as if it were a native JavaScript class. A GlideRecord is an object that contains records from a single table. See GlideRecord.
GlideElement Use this class to operate on the fields of the current GlideRecord. See GlideElement.
GlideSystem Use this class to get information about the system. See GlideSystem.
GlideAggregate Use this class to perform database aggregation queries, such COUNT, SUM, MIN, MAX, and AVG, for creating customized reports or calculations in calculated fields. See GlideAggregate.
GlideDateTime Use this class to perform date-time operations, such as date-time calculations, formatting a date-time, or converting between date-time formats. See GlideDateTime.

Client-side Glide Classes

Class Description
GlideAjax Use this class to execute server-side code from the client. See GlideAjax.
GlideDialogWindow Use this class to display a dialog window. See GlideDialogWindow.
GlideForm Use this class to customize forms. See GlideForm.
GlideList2 Use this class to customize (v2) lists, including normal lists and related lists. See GlideList2.
