SQLMaker Meta Table

The meta table description tells you everything you need to know about the internal SQLMaker table, which contains additional database information about alias names, relations, scripts (not implemented yet) and layouts.

 

structure.txt

Like the structure.txt file for normal tables, this file contains the basic structure and must not be altered.
