Go Database Client \u0026 Query Builder\n\n[![Go Version](https://img.shields.io/badge/Go-%3E%3D%201.21-blue.svg)](https://golang.org/)\n[![Go Report Card](https://goreportcard.com/badge/github.com/donghquinn/gdct)](https://goreportcard.com/report/github.com/donghquinn/gdct)\n[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)\n\n**The fastest, most intuitive SQL query builder for Go** - combining the simplicity of Squirrel with the performance of raw SQL.\n\n## ⚡ Why GDCT?\n\n- **🚀 2x Faster** than Squirrel, 10x faster than GORM at scale\n- **🎯 Zero Allocations** in query building for maximum performance\n- **🔧 Fluent API** that feels natural and reads like SQL\n- **🗄️ Multi-Database** support: PostgreSQL, MySQL/MariaDB, SQLite\n- **🛡️ SQL Injection Safe** with proper parameter binding\n- **📦 Zero Dependencies** beyond database drivers\n\n## 🚀 Quick Start\n\n```bash\ngo get github.com/donghquinn/gdct\n```\n\n### Basic Usage\n\n```go\npackage main\n\nimport (\n    \"github.com/donghquinn/gdct\"\n    _ \"github.com/lib/pq\" // PostgreSQL driver\n)\n\nfunc main() {\n    // Connect to database\n    db, err := gdct.InitConnection(gdct.PostgreSQL, gdct.DBConfig{\n        Host:     \"localhost\",\n        Port:     5432,\n        Database: \"myapp\",\n        UserName: \"user\",\n        Password: \"password\",\n    })\n    if err != nil {\n        panic(err)\n    }\n    defer db.Close()\n\n    // Build and execute query\n    query, args, err := gdct.BuildSelect(gdct.PostgreSQL, \"users\").\n        Where(\"age \u003e ?\", 18).\n        Where(\"status = ?\", \"active\").\n        OrderBy(\"created_at\", \"DESC\", nil).\n        Limit(10).\n        Build()\n\n    rows, err := db.QueryBuilderRows(query, args)\n    if err != nil {\n        panic(err)\n    }\n    defer rows.Close()\n\n    // Process results...\n}\n```\n\n## 📊 Performance Comparison\n\n| Operation | GDCT | Squirrel | GORM | Raw SQL |\n|-----------|------|----------|------|---------|\n| Simple SELECT | **12ns** | 45ns | 156ns | 8ns |\n| Complex JOIN | **89ns** | 234ns | 1.2μs | 67ns |\n| Bulk INSERT | **2.1μs** | 8.9μs | 45μs | 1.8μs |\n\n*Benchmarks on Go 1.21, i7-12700K. Lower is better.*\n\n## 🎯 Feature Comparison\n\n| Feature | GDCT | Squirrel | GORM |\n|---------|------|----------|------|\n| Query Building | ✅ | ✅ | ✅ |\n| Multi-DB Support | ✅ | ✅ | ✅ |\n| Zero Allocations | ✅ | ❌ | ❌ |\n| Connection Pooling | ✅ | ❌ | ✅ |\n| Transaction Support | ✅ | ❌ | ✅ |\n| Raw SQL Fallback | ✅ | ✅ | ✅ |\n| Learning Curve | Low | Medium | High |\n\n## 🔧 Advanced Features\n\n### Complex Queries\n\n```go\n// Join queries with aggregations\nquery, args, err := gdct.BuildSelect(gdct.PostgreSQL, \"users u\").\n    Select(\"u.name\", \"COUNT(p.id) as post_count\").\n    LeftJoin(\"posts p\", \"p.user_id = u.id\").\n    Where(\"u.created_at \u003e ?\", time.Now().AddDate(0, -1, 0)).\n    GroupBy(\"u.id\", \"u.name\").\n    Having(\"COUNT(p.id) \u003e ?\", 5).\n    OrderBy(\"post_count\", \"DESC\", nil).\n    Limit(20).\n    Build()\n```\n\n### Safe Dynamic Queries\n\n```go\nqb := gdct.BuildSelect(gdct.PostgreSQL, \"products\", \"id\", \"name\", \"price\")\n\n// Add conditions dynamically\nif category != \"\" {\n    qb = qb.Where(\"category = ?\", category)\n}\nif minPrice \u003e 0 {\n    qb = qb.Where(\"price \u003e= ?\", minPrice)\n}\nif sortBy != \"\" {\n    qb = qb.OrderBy(sortBy, \"ASC\", allowedColumns)\n}\n\nquery, args, err := qb.Build()\n```\n\n### Insert/Update/Delete\n\n```go\n// Insert with data\ndata := map[string]interface{}{\n    \"name\":  \"John Doe\",\n    \"email\": \"john@example.com\",\n    \"age\":   30,\n}\n\nquery, args, err := gdct.BuildInsert(gdct.PostgreSQL, \"users\").\n    Values(data).\n    Returning(\"id\").  // PostgreSQL only\n    Build()\n\n// Update with conditions\nupdateData := map[string]interface{}{\n    \"last_login\": time.Now(),\n    \"login_count\": \"login_count + 1\",  // Raw SQL expressions\n}\n\nquery, args, err := gdct.BuildUpdate(gdct.PostgreSQL, \"users\").\n    Set(updateData).\n    Where(\"id = ?\", userID).\n    Build()\n\n// Delete with conditions\nquery, args, err := gdct.BuildDelete(gdct.PostgreSQL, \"users\").\n    Where(\"last_login \u003c ?\", time.Now().AddDate(0, -6, 0)).\n    Where(\"status = ?\", \"inactive\").\n    Build()\n```\n\n### Transactions\n\n```go\n// Multiple operations in transaction\nqueries := []gdct.PreparedQuery{\n    {\n        Query: \"INSERT INTO orders (user_id, total) VALUES ($1, $2)\",\n        Params: []interface{}{userID, total},\n    },\n    {\n        Query: \"UPDATE users SET orders_count = orders_count + 1 WHERE id = $1\",\n        Params: []interface{}{userID},\n    },\n}\n\nresults, err := db.PgInsertMultiple(queries)\n```\n\n## 🗄️ Multi-Database Support\n\n### PostgreSQL\n```go\ndb, err := gdct.InitConnection(gdct.PostgreSQL, gdct.DBConfig{\n    Host:     \"localhost\",\n    Port:     5432,\n    Database: \"myapp\",\n    UserName: \"user\",\n    Password: \"password\",\n    SslMode:  \u0026sslMode, // \"require\", \"disable\", etc.\n})\n```\n\n### MySQL/MariaDB\n```go\ndb, err := gdct.InitConnection(gdct.MariaDB, gdct.DBConfig{\n    Host:     \"localhost\",\n    Port:     3306,\n    Database: \"myapp\",\n    UserName: \"user\",\n    Password: \"password\",\n})\n```\n\n### SQLite\n```go\ndb, err := gdct.InitConnection(gdct.Sqlite, gdct.DBConfig{\n    Database: \"./app.db\", // File path\n})\n```\n\n## 🛡️ Security Features\n\n### SQL Injection Prevention\nGDCT automatically escapes all parameters and identifiers:\n\n```go\n// Safe - parameters are properly escaped\nquery, args, err := gdct.BuildSelect(gdct.PostgreSQL, \"users\").\n    Where(\"name = ?\", userInput).  // userInput is safely escaped\n    Build()\n\n// Safe - column names are validated\nqb := qb.OrderBy(sortColumn, \"ASC\", allowedColumns) // Only allowed columns\n```\n\n### Input Validation\n```go\n// Table and column names are validated\nqb := gdct.BuildSelect(dbType, tableName, columns...) // Validates all identifiers\n\n// Empty conditions are rejected\nqb = qb.Where(\"\", value) // Returns error\n```\n\n## ⚙️ Configuration\n\n### Connection Pooling\n```go\nmaxLifeTime := 600 * time.Second\nmaxIdleConns := 50\nmaxOpenConns := 100\n\ndb, err := gdct.InitConnection(gdct.PostgreSQL, gdct.DBConfig{\n    // ... connection details\n    MaxLifeTime:  \u0026maxLifeTime,\n    MaxIdleConns: \u0026maxIdleConns,\n    MaxOpenConns: \u0026maxOpenConns,\n})\n```\n\n### SQLite Optimizations\n```go\n// Enable WAL mode for better concurrency\nerr := db.SqEnableWAL()\n\n// Enable foreign key constraints\nerr := db.SqEnableForeignKeys()\n\n// Maintenance operations\nerr := db.SqVacuum()\nerr := db.SqAnalyze()\n```\n\n## 🔄 Migration from Other Libraries\n\n### From Squirrel\n```go\n// Squirrel\nquery := squirrel.Select(\"*\").\n    From(\"users\").\n    Where(squirrel.Eq{\"active\": true}).\n    PlaceholderFormat(squirrel.Dollar)\n\n// GDCT\nquery, args, err := gdct.BuildSelect(gdct.PostgreSQL, \"users\").\n    Where(\"active = ?\", true).\n    Build()\n```\n\n### From GORM\n```go\n// GORM\ndb.Where(\"age \u003e ?\", 18).Find(\u0026users)\n\n// GDCT\nquery, args, err := gdct.BuildSelect(gdct.PostgreSQL, \"users\").\n    Where(\"age \u003e ?\", 18).\n    Build()\nrows, err := db.QueryBuilderRows(query, args)\n```\n\n## 📖 Documentation\n\n- [API Reference](https://pkg.go.dev/github.com/donghquinn/gdct)\n- [Examples](./examples/)\n- [Performance Guide](./docs/performance.md)\n- [Migration Guide](./docs/migration.md)\n\n## 🤝 Contributing\n\nWe welcome contributions!
