What field type would you select if you want to query records from another table on a form?

Show Suggested Answer Hide Answer
Suggested Answer: D

Comprehensive and Detailed In-Depth

In ServiceNow, to include data from another table within a form, the Reference field type is utilized. A Reference field creates a relationship between the current table and another table by storing a reference to a record in the target table. This allows users to select a record from the referenced table and display related information seamlessly within the form.

A . Use the Date field type: This is incorrect. The Date field type is designed to store date values and does not facilitate referencing records from other tables.

B . Use the Phone Number field type: This is incorrect. The Phone Number field type is intended for storing phone number data and does not support referencing other table records.

C . Use the String field type: This is incorrect. The String field type stores text data and does not inherently provide functionality to reference records from other tables.

D . Use the Reference field type: This is correct. The Reference field type is specifically designed to create a link to a record in another table, enabling the incorporation of related data into the form.

For example, in the Incident table, the 'Caller' field is a reference to the User [sys_user] table, allowing the selection of a user as the caller for the incident. This setup ensures data consistency and leverages existing records without data duplication.

Haha, can you imagine trying to use the Date field type for this? That's like trying to use a screwdriver to hammer in a nail. Nah, the Reference field type is the way to go, easy peasy.

I'm not sure, but I think C) Use the String field type could also work for querying records.

Ooh, the Phone Number field type, that's a bold choice! I bet that would be great for storing... phone numbers. But for querying other tables, gotta be the Reference field type, my dude.

Hold up, are we supposed to be able to call other tables on a form? That sounds like some advanced database wizardry. I'm just going to go with the String field type, keep it simple, you know?

I'm not sure about the Reference field type, I usually just stick with the String field type for basic forms.

I'm pretty sure the Date field type is not the right choice here. That's more for, well, dates! The Reference field type makes the most sense to me.

Hmm, I think the Reference field type would be the way to go. Querying records from another table sounds like a job for a foreign key, don't you think?

Yes, using a foreign key with the Reference field type is the best way to query records from another table.
