Your question is unclear, if not nonsensical. The use of the term, 'compiler', can be stretched to fit, possibly, but if you have to ask the question, you're missing some important background.
Neither Java nor SQL 'compile' to native machine code. Each can be 'pretreated' to reduce overhead under certain circumstances. Some people may refer to this as compilation or pre-compilation.
Java is a programming language. SQL is a database query language. One is an apple and the other is an orange, if you get my drift.
