For eg. '==' tooltip as "Equals", 'Like' tooltip as "Contains", etc

It would be nice if there was a new clause which can be added to queries called callback.

For example:

def callback_handler(success, value):
    if success:
        print(f'The query was successful and returned {value}')
    else:
        print("The query failed")

Band.select().callback(callback_handler).run_sync()

The callback could be a function or coroutine, wh

The .returning() function currently only supports strings (which should be the target table's column names). In reality they can accept any expression and (returning) query.

This should be supported:

insert into bar (val) values (123) returning (select count(*) from bar), id, val || 'test'

which would equate to something like:

db.insertInto(bar).values({ val: 123 })

Summary

Implement the sqlx::IntoArguments trait for sea_query::Values, for the various DB types (sqlite, posgres, ...)

Motivation

When writing injection-free code with sqlx, the best would be to write in this style:

let (query, values) = Query::select()
    ...
    .cond_where(Expr::col(Users::UserId).eq(user_i
