GlideRecord


Just like the server-side version, GlideRecord is used to perform database operations on records within ServiceNow, such as querying, modifying, and creating records. The client-side version of the GlideRecord API only contains a subset of the methods available on the server, but it does enable one important new piece of functionality: callback functions.

The query() method of the client-side GlideRecord, as well as insert(), and deleteRecord(), all accept callback functions. In fact, each of these methods should never be called from a client-side script without a callback function.

The full list of documented methods in the client-side GlideRecord API is:

  • addOrderBy()

  • addQuery()

  • deleteRecord()

  • get()

  • getEncodedQuery()

  • getLimit()

  • getTableName()

  • hasNext()

  • insert()

  • next()

  • orderBy()

  • query()

  • setLimit()

In this section, we'll learn about a few of these methods which are commonly used, and which differ from their server-side cousins. This means that we won't be re-hashing...
