+# GlideRecord Conditional Batch Update
+
+## Description
+This snippet updates multiple records in a ServiceNow table based on a GlideRecord encoded query.  
+It logs all updated records and provides a safe, controlled way to perform batch updates.
+
+## Prerequisites
+- Server-side context (Background Script, Script Include, Business Rule)
+- Access to the table
+- Knowledge of GlideRecord and encoded queries
+
+## Note
+- Works in Global Scope
+- Server-side execution only
+- Logs updated records for verification
+- Can be used for maintenance, bulk updates, or automated scripts
+
+## Usage
+```javascript
+// Update all active low-priority incidents to priority=2 and state=2
+batchUpdate('incident', 'active=true^priority=5', {priority: 2, state: 2});
+```
+
+## Sample Output
+```
+Updated record: abc123
+Updated record: def456
+Updated record: ghi789
+Batch update completed. Total records updated: 3
+```
