DataPup + +## โœ… Implementation Complete + +This document outlines the comprehensive pagination feature that has been implemented in DataPup to automatically limit SELECT query results to 100 records by default and provide pagination controls. + +## ๐Ÿš€ Features Implemented + +### Backend Implementation + +1. **Database Interface Updates** (`src/main/database/interface.ts`) + - Added `PaginationOptions` interface with `page` and `limit` parameters + - Added `PaginationInfo` interface with complete pagination metadata + - Extended `QueryResult` to include pagination information + - Updated `query()` method signature to accept optional pagination parameters + +2. **Base Database Manager** (`src/main/database/base.ts`) + - Smart SQL parsing to detect existing LIMIT clauses + - Automatic LIMIT/OFFSET injection for SELECT queries + - Logic to respect user-specified LIMIT clauses when smaller than page size + - Helper methods for pagination metadata generation + +3. **ClickHouse Implementation** (`src/main/database/clickhouse.ts`) + - Automatic pagination for SELECT queries only + - Total count calculation using `SELECT COUNT(*) FROM (query)` + - Efficient pagination with proper LIMIT/OFFSET syntax + - Enhanced result messages showing pagination status + +4. **IPC Layer** (`src/main/index.ts`) + - Updated `db:query` handler to accept pagination parameters + - Maintains full backward compatibility + +### Frontend Implementation + +5. **Type Definitions** (`src/renderer/types/tabs.ts`) + - Added `PaginationInfo` interface matching backend structure + - Extended `QueryExecutionResult` with pagination data + +6. **Pagination Component** (`src/renderer/components/Pagination/`) + - Reusable pagination component with full navigation controls + - Page size selector (25, 50, 100, 200, 500 rows) + - Current page, total pages, and record count display + - Proper disabled states and accessibility + +7. **Enhanced Export Functionality** (`src/renderer/components/ExportButton/`) + - Smart export component with pagination awareness + - Dropdown options for "Current Page" vs "All Data" export + - Automatic filename generation with pagination context + - Support for CSV, JSON, and SQL export formats + +8. **Query Workspace Integration** (`src/renderer/components/QueryWorkspace/`) + - Per-tab pagination state management + - Integrated pagination controls in results section + - Page navigation and size change handlers + - Export functionality for both current page and all data + +## ๐Ÿ”ง How It Works + +### Automatic Pagination Logic + +1. **Query Analysis**: The system detects if a query is a SELECT statement +2. **LIMIT Detection**: Checks for existing LIMIT clauses in user queries +3. **Smart Application**: + -
