Comprehensive Example + +This example demonstrates the full capabilities of the GORM DuckDB driver, showcasing all major features and fixes implemented in this driver. + +## Features Demonstrated + +### ✅ Array Support + +- **StringArray**: Categories field in Product model +- **FloatArray**: Scores field in Product model +- **IntArray**: ViewCounts field in Product model +- Array creation, retrieval, and updates + +### ✅ Auto-Increment with Sequences + +- Automatic sequence generation (`seq_tablename_id`) +- RETURNING clause for ID retrieval +- Works across all models (User, Post, Tag, Product) + +### ✅ Migrations and Schema Management + +- Auto-migration support +- Custom migrator with DuckDB-specific optimizations +- ALTER TABLE syntax fixes for DuckDB + +### ✅ Data Types and Time Handling + +- Various numeric types (uint, uint8, float64) +- String fields with size constraints +- Time fields (time.Time) with manual control +- Proper type mapping for DuckDB + +### ✅ CRUD Operations + +- Create with auto-increment IDs +- Read operations with filtering +- Update operations (single field and multiple fields) +- Delete operations +- Batch operations + +### ✅ Advanced Features + +- Complex queries with WHERE, GROUP BY, aggregations +- Transactions with rollback support +- Analytical queries (AVG, COUNT, CASE statements) +- Database state reporting + +## Key Fixes Demonstrated + +### ALTER TABLE Syntax Fix + +**Problem**: DuckDB doesn't support `ALTER COLUMN ... TYPE ... DEFAULT ...` syntax +**Solution**: Custom migrator splits DEFAULT clauses from type changes +**Result**: ✅ No more "syntax error at or near 'DEFAULT'" errors + +### Auto-Increment Implementation + +**Problem**: DuckDB doesn't have native AUTO_INCREMENT +**Solution**: Custom sequences with RETURNING clause +**Implementation**: + +```sql +CREATE SEQUENCE seq_users_id START 1 +CREATE TABLE users (id BIGINT DEFAULT nextval('seq_users_id') NOT NULL, ...) +INSERT INTO users (...) VALUES (...) RETURNING "id" +``` + +### Array Type Support + +**Problem**: Go doesn't have native array types for DuckDB +**Solution**: Custom array types with proper serialization +**Types**: StringArray, FloatArray, IntArray + +## Running the Example + +```bash +cd example +go run main.go +``` + +**Note**: This example uses an in-memory database (`:memory:`), so all data is cleaned up automatically when the program exits. + +## Output + +The example produces detailed output showing: + +1. **Connection and Migration**: Database setup and schema creation +2. **CRUD Operations**: User creation, reading, updating, and deletion +3. **Array Operations**: Product creation with arrays and array updates +4. **Advanced Queries**: Analytics, demographics, and transaction examples +5. **Final State**: Summary of all created records + +## Model Definitions + +### User Model + +```go +type User struct { + ID uint `gorm:"primaryKey;autoIncrement"` + Name string `gorm:"size:100;not null"` + Email string `gorm:"size:255;uniqueIndex"` + Age uint8 + Birthday time.Time + CreatedAt time.Time `gorm:"autoCreateTime:false"` + UpdatedAt time.Time `gorm:"autoUpdateTime:false"` +} +``` + +### Product Model (with Arrays) + +```go +type Product struct { + ID uint `gorm:"primaryKey;autoIncrement"` + Name string `gorm:"size:100;not null"` + Price float64 + Description string + Categories duckdb.StringArray // Array support + Scores duckdb.FloatArray // Float array support + ViewCounts duckdb.IntArray // Int array support + CreatedAt time.Time + UpdatedAt time.Time +} +``` + +## Performance Notes + +- DuckDB excels at analytical workloads (OLAP) +- Arrays are stored efficiently in DuckDB's columnar format +- Transactions are lightweight but have different isolation semantics than traditional RDBMS +- Auto-increment sequences perform well for moderate insert rates + +## Limitations Addressed + +1. **Relationship Complexity**: This example focuses on core functionality rather than complex GORM relationships +2. **DuckDB-Specific Syntax**: All SQL generation respects DuckDB's dialect limitations +3. **Array Operations**: Advanced array querying would require raw SQL for complex operations + +## Next Steps + +After running this example, you can: + +1. Modify the models to test your specific use cases +2. Add more complex queries using raw SQL +3. Test with file-based databases instead of in-memory +4. Explore DuckDB's analytical capabilities with larger datasets + +This example serves as both a test suite and a reference implementation for the GORM DuckDB driver. diff --git a/example/go.mod b/example/go.mod index 8285751..033498a 100644 --- a/example/go.mod +++ b/example/go.mod @@ -2,14 +2,13 @@ module example go 1.24 -toolchain go1.24.4 -
