Database Numeric Display Drift

cluster-40

Floating-point and numeric types get rendered differently across tools and SQL queries, so values like NUMERIC(5,1) may appear rounded or altered (including missing separators or unexpected precision), breaking comparisons and display expectations.

INSTANCE_OFProblem

How to bind two input to act as date range? — I have data comming from an api like:. Tension: Date is comming as a string how can we filter in them? Outcome: What is the best way to solve this kind of issue of date range??

INSTANCE_OFProblem

it will display, for example `1029.6`, however I want a dash between then first and second digit — In my database I have an entry for a `NUMERIC(5,1)`. Tension: the number should be 1000<=n<6000. Outcome: how can I do this?

INSTANCE_OFProblem

The typemod rounds values above your specified precision. Tension: it complains before the `check` constraint. Outcome: 3333.8.

INSTANCE_OFProblem

ERROR: numeric field overflow. Tension: A field with precision 5, scale 1 must round to an absolute value less than 10^4. Outcome: ERROR: numeric field overflow.

INSTANCE_OFProblem

A PostgreSQL DATE column (start_date) queried via Vercel Postgres/Neon is returned in the client as a full ISO timestamp string with timezone (e.g., 2025-02-06T16:00:00.000Z) instead of the expected YYYY-MM-DD date format.

INSTANCE_OFProblem

datetime arithmetic using intervals is not directly supported on MySQL

INSTANCE_OFProblem

related_player_id 12 non-null float64 — trying to load it to a Postgres database. Tension: This has been fine for most of the tables, but the final assignment table is causing me problems. Outcome: bigint out of range.

INSTANCE_OFProblem

sort product names in a natural way. Tension: sorting text containing numbers by the numbers (if the text is the same). Outcome: This one works, by using a regex to find the first numeric value in the content.

INSTANCE_OFProblem

the actual return result was `2025-02-12T06:30:04-05:00` — For timestamp with timezone, the internally stored value is always in UTC. Tension: which represents a timestamp in US/Eastern rather than UTC. Outcome: Only the display differs.

INSTANCE_OFProblem

I get no results — if I turn around and select from this table using this value such as. Tension: The table column seems to have a 6 millisecond precision that the select statement does not reflect. Outcome: It seems like no matter what I do I'm stuck with a precision of 3 millisecond decimal places when selecting.

INSTANCE_OFProblem

Creating a generated column by using a PL/pgSQL function returned an error indicating the function returned more than one row. The function was defined to return a single int but the query inside effectively produced results for multiple rows in amp_pumpstations.

INSTANCE_OFProblem

Generated always column cannot use a non-immutable age calculation based on CURRENT_DATE and inservice

INSTANCE_OFProblem

How do I check if the timestamp is not between (start_hour1 and end_hour1) and (start_hour2 and end_hour2). — I have a table look like below. Tension: start_hour2 and end_hour2 could be null as well.

INSTANCE_OFProblem

this record is inserted with the date and time from my local host and not from the database server — inserting a new record into my PostgreSQL database. Tension: The time on this server is different than on my localhost.

INSTANCE_OFProblem

Type 'number[]' is missing the following properties from type 'GridRowSelectionModel': type, idsts(2739) — property 'rowSelectionModel' which is declared here on ty. Tension: no matter what I try, I'm unsuccessful.

INSTANCE_OFProblem

Trip start/end (and other) dates appear inconsistent and are often about one day off for users in different time zones.

INSTANCE_OFProblem

How can I truncate a temporal value to tenths of a second? — In Java, I can easily truncate a temporal value (`LocalTime`, `ZonedDateTime`, etc.). Tension: I was hoping to avoid that if possible. Outcome: I can certainly roll my own "tenths of second" `TemporalUnit` and truncate to that.

INSTANCE_OFProblem

JMX method invocation fails when passing java.time.Instant as a parameter

INSTANCE_OFProblem

I want map 1 field using several arguments, but not all arguments — @Mapping(target = "ss", source = ".", qualifiedByName = "sumThree"). Tension: Is it possible?

INSTANCE_OFProblem

Unable to parse the date: 2025-03-09T02:37:51.742. Tension: All the dates are working before and after that one hour.

INSTANCE_OFProblem

my SQLite Integers into a Java int which only holds 32 bits. Tension: I'd like it to put those values into a long instead.

INSTANCE_OFProblem

Creating OffsetDateTime from LocalDateTime at Europe/Paris is ambiguous during the DST overlap

INSTANCE_OFProblem

From simply looking at the code, `get` giving an error is obvious to me. — raw type is used in `Sub extends Super`. Tension: For backward compatibility, Java allows a non-generic method in subclass to override a generic method in superclass as long as they have the same erasure. Outcome: `get` giving an error is obvious to me.

INSTANCE_OFProblem

I need to retrieve some data from the db and I need to check if the given date matches the one in the table — I am converting the `String` I get from the front end app, transform it in a `java.util.Date` and then in a `LocalDateTime`. Tension: Is this approach correct, or am i missing something? Outcome: Format of the string from the front end and also stored in db: 2025-01-29 15:09:57.475000.

INSTANCE_OFProblem

Casting Iterator<SubClass> to Iterator<SuperClass> is rejected even when the iterator is read-only

INSTANCE_OFProblem

Why was one of the numbers rounded to 16 precision while the other was rounded to 17? — System.out.printf("x = %.20f , y = %.20f%n", x, y);. Tension: Why aren't they both 16 precision? Or why aren't they both 17 precision? Outcome: why the precisions are different?

INSTANCE_OFProblem

datetime(3) values lose trailing .000 fractional seconds when read back, breaking parsing

INSTANCE_OFProblem

a time zone abbreviation such as `PST` — whether the user is in the Philippines, US, Canada, etc. Tension: both provide an exhaustive list and don't give any guidance on which to pick. Outcome: a lot closer than having to guess when we get an ambiguous time zone as input.

INSTANCE_OFProblem

Quarkus - JAXB with OffsetDateTime?

INSTANCE_OFProblem

I don't understand when the very last disambiguation (using `round_to_nearest`) would actually happen. — If there are several such representations, the representation with the smallest difference from the floating-point argument value is chosen. Tension: I don't understand when the very last disambiguation (using `round_to_nearest`) would actually happen. Outcome: These examples are hypothetical, but they show when th.

INSTANCE_OFProblem

But I only get 12-18. — How can I get all of those url parameters (1, 12-18, 5,Happy birthday) in Django? Outcome: I only get 12-18.
