SQLBuilder

SQLBuilder is a lightweight, cross‑platform library designed to simplify the construction of SQL statements in application code. It provides a fluent API that allows developers to build SELECT, INSERT, UPDATE, and DELETE queries by chaining method calls rather than concatenating strings. The library is implemented in several mainstream programming languages, including Java, Python, C#, and JavaScript, and is distributed under permissive open‑source licenses.

The primary motivation behind SQLBuilder is to promote safer, more maintainable code. By abstracting the syntax of SQL into a programmatic interface, the library reduces the risk of syntax errors and SQL injection attacks. Parameter placeholders are automatically handled, and values are bound using prepared statement mechanisms supplied by the host language’s database driver. The builder also supports table and column aliasing, joins, grouping, ordering, pagination, and condition composition with logical operators.

Developers often integrate SQLBuilder into ORMs or data access layers to add flexibility for complex queries that fall outside the scope of the automated mapping facilities. In many projects, it is used alongside transaction management frameworks, allowing statements to be composed and executed within a consistent transactional context. The API offers both a declarative style—using lambda functions or builder callbacks—and a programmatic style where developers explicitly instantiate query objects.

SQLBuilder first appeared as a small community library in 2012, and it has since seen contributions from multiple developers worldwide. Its design aims for compatibility with SQL dialects such as MySQL, PostgreSQL, Oracle, and SQLite, ensuring that generated statements are syntactically correct across different database engines. The project maintains documentation and example scripts to assist new users in integrating the builder into legacy and modern applications alike.
