Enhance table_info.sql

[martindsouza]

It's missing a ton of information. I think there could be a lot more. Need to also think of it's structure.

I see you are missing a lot of extra stuff

• Column COMMENTS
• Table COMMENT
• DATA_TYPE_DESC -- returns VARCHAR2(30 CHAR) instead of just VARCHAR2
• NULLABLE column should be decoded to use the same values as "VIRTUAL_COLUMN" and "HIDDEN_COLUMN" columns
  • for {{#if}} to work, the boolean columns should be decoded to 1 or 0
• USER_GENERATED -- column for 12c+ or a calculated version for pre-12c
• SYSTEM_GENERATED -- Inverse of USER_GENERATED. Used for filtering.

Let me know if you are still working on this repository. (you still have an outstanding PULL REQUEST)
