null VS trdsql

Use-case: working on PATCH requests, the body may or may not contain nullable values. I am using guregu/null and I can't use a pointer because if the json contains "null" as a value, the pointer will be set to nil in the struct, instead of a value representing the presence of null. In short I can't differentiate the absence of the field in the request from the presence of the field with a null value.

https://github.com/guregu/null is an awesome package implementing most SQL scanner Interfaces plus JSON

There’s also this: https://github.com/guregu/null

Unfortunately in Go, switching to *bool makes the api a little more awkward to use since users that need to set true or false have to define a local variable then use a pointer to that. Another option would be something like null, but that adds a dependency to your currently-dependency-free project. If anyone has a better solution to this pattern, I'd love to hear it.

Apparently, there were many who thought the same thing; Tools to execute SQL against CSV were trdsql, q, csvq, TextQL. They were highly functional, hoewver, had many options and no input completion. I found it just a little difficult to use.

Nice! Kinds of reminds me of trdsql

trdsql(https://github.com/noborus/trdsql) is a tool that executes SQL for files such as CSV, but it can also be used by connecting to MySQL. Therefore, SQL such as CREATE TABLE table AS SELECT * FROM csvfile.csv can also be executed.

trdsql can execute SQL against CSV, LTSV, JSON and TBLN, and the database can also use SQLite,PostgreSQL and MySQL.

The trdsql I made is feature-rich and fast (as a similar SQL tool).
