## Neo4j Version Compatibility Notes
|
|
|
|
Neo4j had significant breaking changes between version 4.x and 5.x regarding schema introspection:
|
|
|
|
**Neo4j 5.x+ (current):**
|
|
- Use `SHOW INDEXES` instead of `CALL db.indexes()`
|
|
- Use `SHOW CONSTRAINTS` instead of `CALL db.constraints()`
|
|
- Use `CALL db.schema.visualization()` for full schema (works in both versions)
|
|
|
|
**Neo4j 4.x and earlier:**
|
|
- Use `CALL db.indexes()`
|
|
- Use `CALL db.constraints()`
|
|
|
|
**Safe queries that work across versions:**
|
|
- `CALL db.schema.visualization()` - Full schema visualization
|
|
- `CALL db.labels()` - Get all node labels
|
|
- `CALL db.relationshipTypes()` - Get all relationship types
|
|
|
|
When querying indexes or constraints, prefer the `SHOW` commands for Neo4j 5+ environments. |
