## Quick Reference
141+
142+
### New SQL Functions (3)
143+
144+
```sql
145+
-- 1. Check if current
146+
SELECT gaggle_is_current('owner/dataset');
147+
-- Returns: BOOLEAN
148+
149+
-- 2. Force update
150+
SELECT gaggle_update_dataset('owner/dataset');
151+
-- Returns: VARCHAR (path)
152+
153+
-- 3. Get version info
154+
SELECT gaggle_version_info('owner/dataset');
155+
-- Returns: VARCHAR (JSON)
156+
```
157+
158+
### Common Patterns
159+
160+
**Pattern 1: Check before query**
161+
```sql
162+
SELECT gaggle_is_current('owner/dataset');
163+
-- If false, consider updating
164+
```
165+
166+
**Pattern 2: Conditional update**
167+
```sql
168+
SELECT CASE
169+
WHEN gaggle_is_current('owner/dataset')
170+
THEN gaggle_download('owner/dataset')
171+
ELSE gaggle_update_dataset('owner/dataset')
172+
END;
173+
```
174+
175+
**Pattern 3: Version audit**
176+
```sql
177+
SELECT
178+
json_extract_string(gaggle_version_info('owner/dataset'), '$.cached_version'),
179+
json_extract_string(gaggle_version_info('owner/dataset'), '$.latest_version'),
180+
json_extract_string(gaggle_version_info('owner/dataset'), '$.is_current');
181+
```
182+
183+
