In the future, the SQL parsing engine will continue to provide powerful functions such as SQL formatting and SQL templating. Features • Independent SQL parsing engine • The syntax rules can be easily which column is used to store cipher column data (cipherColumn), which column is used to store plain text data (plainColumn), and which column users want to use for SQL writing (logicColumn) How to understand column name of cipherColumn. Or delete plainColumn and choose to never store plain text and only store cipher text. As long as the user’s SQL is written according to this logical column, and the correct
