chore!: Change H2 Oracle longType and longAutoincType from NUMBER(19) to BIGINT and add CHECK constraint in Oracle and SQLite

[joc-a]

Description

Detailed description:

• What:
  The SQL type of H2 Oracle Long type were changed. A CHECK constraint was also added for SQLite and Oracle.
• Why:

1. H2 enforces the range on its own when BIGINT is used.
2. It is a preparation step for making detecting column type change for migration easier

• How:
  The CHECK constraint with a range doesn't reject out-of-range values in SQLite because SQLite can store values that exceed the 64-bit integer range as REAL (floating-point numbers), bypassing the constraint. Using the condition typeof(long_column) = 'integer' instead of the range ensures that only 64-bit integer values pass the check, preventing out-of-range values from being stored as REAL and slipping past the constraint. The reason all of this is done the createStatement() function and not in the column creation function as usual is because we need to invoke currentDialect to check the dialect and construct the CHECK constraint accordingly, and this cannot be invoke in the column creation function.

I don't know if it's ok or not, but to me it looks a bit suspicious at the current moment.

We actually modify the table object, so user will have changes in table object if he tries to create statement for that table.

The method createStatement() does not look like the one that should modify table object, so some users may be surprised

@obabichevjb I agree. I didn't like this solution, to be frank, but I didn't have any other ideas. If you have any suggestions on how to do this in a cleaner way, please let me know.

It's a good question, I'm not sure about what is the behavior we want to achieve.

If we want to guarantee that only long values would be stored in the database base and exception would be thrown otherwise, it could be problematic (like in the PR)

I tried to check SQLite, and I found out that if the column type INTEGER is used, then the column will store only Kotlin's Long values. But it would not complain if the user tried to save the value beyond Long.MIN_VALUE/Long.MAX_VALUE, it will just "cut" the values to the range.
