favorite <https://stackoverflow.com/questions/51547864/apache-calcite-and-sql-parsing?noredirect=1#> I am working on a project that needs to connect to the database to retrieve the SQL Statements. Once I retrieved the SQL queries then I need to parse these SQL statement Conditions*/Qualifiers* and store them in a memory for doing some comparisons later on. I did some research and I came across Apache Calcite. As per the website link <https://calcite.apache.org/docs/>, it supports query parsing, validation, and optimization. The database that I want to connect is *Oracle DB* to retrieve the queries( like SELECT,WITH). Can you provide any info on how to get started for this and am I going in right direction in going with Apache Calcite? Thanks, Srikanth.
