surprising query parent-child
  • No, there is no Docker image just a bunch of classes for data and operation
  • It's a default parent-child construct. And some utility classes.
  • Take care in the description! A mix of Upper-Lower-case may cause problems.
  • Analyzing the provided code I had 2 surprises:
    • Why manually scan the index Global with $O() instead of SQL + SesultSet ?
    • Why manually composing the result instead of using SQL functions JSON_ARRAY
      and JSON_OBJECT ??
  • besides readability of JSON.
