🎯 COMPLETE TABLE CREATION FIX & GORM BUG REPORTING

🏆 MAJOR ACHIEVEMENT: Successfully identified, fixed, and reported critical table creation bug + filed upstream GORM bug report.

This release represents the complete resolution of the table creation issues that were blocking core functionality, plus the successful identification and reporting of a critical GORM callback bug to the upstream project.

✨ Major Achievements

  • 🔧 Complete Table Creation Fix: Resolved root cause - parent GORM migrator bypassing convertingDriver wrapper
  • 🛠️ Custom CreateTable Implementation: Complete rewrite using direct SQL generation and sqlDB.Exec() calls
  • ⚡ Auto-Increment Resolution: Implemented proper sequence-based auto-increment with DEFAULT nextval() syntax
  • 🐛 GORM Bug Discovery: Identified critical bug in GORM's RowQuery callback causing Raw().Row() to return nil
  • 📝 Upstream Bug Report: Filed comprehensive bug report (GORM Issue #7575) with reproduction case and working fix

🔧 Technical Implementation

Complete Migrator Rewrite

  • Root Cause: Parent GORM migrator calls bypassed convertingDriver wrapper, preventing table creation
  • Solution: Complete CreateTable method rewrite with direct SQL generation
  • Sequence Management: Automatic CREATE SEQUENCE for auto-increment fields
  • Direct Execution: Uses sqlDB.Exec() instead of parent migrator calls
// Before: Parent migrator call (broken)
return m.Migrator.CreateTable(value)

// After: Direct SQL execution (working)
_, err := sqlDB.Exec(createTableSQL)
_, err = sqlDB.Exec(createSequenceSQL)

GORM RowQuery Callback Bug

  • Bug Discovered: GORM's default RowQuery callback fails to set Statement.Dest causing Raw().Row() to return nil
  • Impact: Nil pointer panics in production applications using Raw().Row()
  • Workaround: Custom rowQueryCallback properly calls QueryRowContext() and assigns result
  • Upstream Report: Filed GORM Issue #7575 with comprehensive analysis and working fix

🧪 Complete Compliance Achievement

  • ✅ All Tests Passing: TestGORMInterfaceCompliance now passes 100%
  • ✅ Table Creation Working: HasTable, GetTables, ColumnTypes all functional
  • ✅ Auto-Increment Fixed: Proper sequence-based auto-increment with DEFAULT nextval()
  • ✅ End-to-End Functionality: Complete example applications working
  • ✅ Production Ready: Comprehensive error handling and logging

📊 Validation Results

  • HasTable: Returns correct boolean for table existence ✅
  • GetTables: Returns proper table list ✅
  • ColumnTypes: Returns complete column metadata ✅
  • TableType: Returns table information ✅
  • BuildIndexOptions: Generates correct index DDL ✅
  • Auto-Increment: Proper sequence creation and DEFAULT clauses ✅
  • Raw().Row(): Working with custom callback workaround ✅

🎯 Production Readiness

  • Comprehensive Logging: Detailed debug logging for all driver operations
  • Error Translation: Complete error handling via translateDriverError function
  • Interface Compliance: Full database/sql/driver interface implementation
  • GORM Compatibility: 100% compliance with GORM interface requirements
  • Future-Proof Design: Conditional workarounds for eventual upstream fixes
