Given table metadata (name, columns/types, etc.), generate a well-formed SQL string. For example: String[] columns = { "a", "b" }; assertEquals("select a,b,c from x", sql.select(tableName, columns));

Do this for the usual SQL queries: SELECT, INSERT, UPDATE, DELETE. To simplify the problem, consider only this data types: strings, integers and booleans.

Remember to only do one thing at a time, and try not to think of the solution "ahead of time". Let the methods and objects just grow by themselves, as you write more and more tests.

Don't forget: Try to use TDD to write code. Free Spanish book here. Write unit tests for generated code. Try to apply SOLID Principles.
