Query.jl to SQL translation

I want to write code to translate the syntax supported by Query.jl into SQL. Then, the queries can be sent to a variety of database softwares. I can take inspiration from implementations in other programming languages (notably LINQ). This work will benefit any user who works with tabular data in Julia. The process to translate code to work optimally with columns might overlap with the process of translating code into SQL. If I am successful translating to SQL code, I will start working on column-based optimizations afterwards
