In ServiceNow, GlideRecord is a JavaScript object used for database operations, such as querying, inserting, updating, and deleting records in tables. It provides a way to interact with records in the ServiceNow database using server-side scripting.
Here's a basic overview of how to use GlideRecord:
Instantiate a GlideRecord object: To work with a specific table in ServiceNow, you first need to create an instance of the GlideRecord object for that table. You can do this by specifying the table name when creating the object. For example:
javascript
Copy code
var gr = new GlideRecord('incident');
Query for records: You can use the addQuery() method to specify conditions for your query and then use the query() method to execute the query. For example, to query all open incidents:
javascript
Copy code
gr.addQuery('active', true); // active=true means open incidents
gr.query();
Iterate through records: After querying, you can use a while loop to iterate through the result set and perform actions on each record. For example:
javascript
Copy code
while (gr.next()) {
// Access fields of the record
var shortDescription = gr.getValue('short_description');
var assignedTo = gr.getValue('assigned_to');
// Perform operations on the record
// ...
}
Insert, update, or delete records: You can use GlideRecord to insert new records, update existing records, or delete records. Here are some examples:
Insert a new record:
javascript
Copy code
gr.initialize(); // Initialize a new record
gr.setValue('short_description', 'New Incident');
gr.setValue('description', 'This is a new incident record.');
gr.insert();
Update an existing record:
javascript
Copy code
if (gr.get('sys_id', 'incident_sys_id')) {
gr.setValue('short_description', 'Updated Incident');
gr.update();
}
Delete a record:
javascript
Copy code
if (gr.get('sys_id', 'incident_sys_id')) {
gr.deleteRecord();
}
Remember to replace 'incident' with the name of the specific table you want to work with and adapt the field names and conditions to your use case. GlideRecord is a powerful tool for working with data in ServiceNow, and it allows you to perform complex database operations in your server-side scripts.
