personalDatabase 2.2.5

Description:

personalDatabase 2.2.5

Notes

about insert command
It is under the category of edit commands, which require committing after making the change.

Bug

insert method only allows for single insert and not bulk insert.
Corrected by changing a condition that checks if new table count is not one more than the previous table count to checking if both are the same. If they are, means that there is a problem, so return error.

Column types


timestamp


Concepts

timestamp

Base:

Minimum number of digits: 10
Any lower precision involve turning beginning digits to 0.


precision levels:
10 digits: seconds
13 digits: Millisecond
16 digits: microseconds
precision in python:

seconds: timestamp(0)
milliseconds: timestamp(3)

Foundation: Changed insert function operation (see .2 and .3) such that it allows for bulk insert in a single command.

New operation - If the new table state (count) is equal to the previous table state, return an error.

add:
fixed:

log_data package import problem involving conflicts due to codependency between log package and this package.

[2.2.3] - 2024-06-19
add:
fixed:

In foundation, custom_logger class init cannot find any class called foundation(the database class). Attempting to rearrange custom_logger to the bottom of the foundation file to solve the problem.
