If you’re a ServiceNow developer, you know that GlideRecord is at the heart of scripting and querying in ServiceNow. But are you using it to its full potential? In this week’s "Did You Know" episode, Kristy shares six GlideRecord tips that can improve your scripts and take your query performance to the next level.

###

### **1\. Boost Performance with `addExtraFields`**

Fetching related fields on reference records can often lead to multiple queries. With the `addExtraFields` method, introduced in the Washington release, you can grab these fields upfront, reducing unnecessary lookups and improving performance.

### **2\. Use `initialize` vs. `newRecord` for Custom Records**

When creating records programmatically, understanding the difference between `initialize` and `newRecord` is key. While `initialize` sets up a GlideRecord object without populating default values, `newRecord` includes defaults based on table configurations.

### **3\. Simplify Queries with `addEncodedQuery`**

Save time by using `addEncodedQuery` for advanced filters. Whether replicating UI filters or dynamically building queries, this method streamlines complex conditions in just one line.

### **4\. Optimize Subqueries with `addJoinQuery`**

Efficiently retrieve related records by using `addJoinQuery`. It’s perfect for scenarios where filters or conditions are applied to related data, minimizing the need for multiple queries.

### **5\. Dynamically Discover Fields with `getFields`**

Working with dynamic or unknown schemas? The `getFields` method lets you retrieve a table’s field names programmatically. It’s invaluable for debugging or creating flexible scripts.

### **6\. Implement Pagination with `chooseWindow`**

Pagination and batch processing become effortless with `chooseWindow`. Limit your query results to a specific range, ideal for scenarios like loading records in chunks or managing large datasets. Pair this with sorting methods like `orderBy` for consistent results.

### **Best Practices for GlideRecord**

* Always index your query fields to enhance performance.
* Combine pagination methods with sorting to avoid inconsistencies.
* Use dynamic scripting techniques to adapt to changing table structures.

**Conclusion**
These GlideRecord tips can save you time, reduce errors, and help you write cleaner, more efficient scripts. Which tip did you find most useful? Share your thoughts in the comments, and don’t forget to catch the next episode of "Did You Know" for more ServiceNow insights!
