Sqlephant
Sqlephant is a desktop SQL development companion from Kawansoft that turns short schema definitions into typed database code. You describe tables with a compact notation, and it predicts column types, builds DTOs, fixes broken SQL statements, and generates language-specific wrappers plus CRUD functions for C#, Java, PHP, and Python.
Where most SQL assistants stop at query completion, Sqlephant focuses on the codegen layer around your schema. Its patent-pending SQL injection fixer runs in Batch Mode so you can submit every application file in one click, and the tool works only on metadata so corporate row data never leaves your machine.
Backend and full-stack developers who maintain multi-language codebases get the most from Sqlephant. Windows, macOS, and Linux builds install without admin or root privileges, and the full-featured version is free with no credit card required.
Compact schema language uses t for CREATE TABLE, * for primary keys, and nn for NOT NULL while inferring column types automatically
Generates SQL wrappers with DTO mapping for C#, Java, PHP, and Python from queries dropped into the editor
Patent-pending SQL injection fixer includes Batch Mode to scan all application files with one click
CRUD generation produces Create, Read, Update, and Delete functions plus matching DTOs from a selected SQL table
Runs on Windows, macOS, and Linux without admin or root privileges
Processes only database metadata; requests are discarded after completion and corporate data is not sent
Full-featured free version requires no credit card at signup
Desktop builds for Windows, macOS, and Linux install without admin or root privileges
Batch Mode scans all application files for SQL injection issues in one click
Wrapper generation covers C#, Java, PHP, and Python from the same SQL query
Web App Generation is still marked Coming Soon on the homepage
Requires a desktop download rather than a browser-based SQL editor
Schema input uses a proprietary shorthand notation you must learn first
