Free online SQL to entity class converter, no installation required. Convert CREATE TABLE to C# or Java classes
What is SQL to Entity Conversion?
SQL to Entity conversion automatically generates object-oriented class code (C# or Java) from SQL CREATE TABLE statements. This saves time when building data models, ORMs, or data access layers by eliminating manual class creation.
How to Use This Converter
Paste your SQL CREATE TABLE statement in the input area. Select your target language (C# or Java). Click Convert to generate the entity class with proper types, annotations, and mappings. The generated code includes attributes for primary keys, nullability, and column names.
Supported SQL Dialects
This tool supports SQL Server, MySQL, PostgreSQL, and other standard SQL syntax. It recognizes common data types (INT, VARCHAR, DATETIME, etc.) and maps them to appropriate language types. For complex schemas, convert one table at a time.
