Hi,   I work with Florian and have additional information about the issue.   First: It is easy to verify that a query on a large table (>500k rows) returns different rows for the same "first" and "skip" arguments when OrderBy is not given. (You have to skip ca 300k rows to trigger the problem.)   Second: The model information query for columns (Model information | Documentation (vismasoftware.no)) does not return information about which columns constitute the PK of the table. Because composite PKs are possible, the model information query should flag each PK column with its physical position in the composite PK. Requesting ordering by PK columns in different order than their physical order will return a correct result, but with a heavy performance hit. (Example: if a table has schema (A, B, C, D) with (A, B) as composite PK, then column A should be flagged with "PK[0]" and column B with "PK[1]".)   Third: Using GraphQL schema introspection query, it is possible to get a "description" for each column. The "description" for PK columns begins with "[PK]", but there is no indication of the column's physical position in the PK.   Lastly: The GraphQL API exposes date and time columns both as integers and as "proper" date/time types (with "AsDate", "AsTime" suffix). The schema introspection query flags both the "int" column and "AsDate" column as PK, presumably because they map to the same physical column. The "AsDate"/"AsTime" columns should never be flagged as PK (when present in the PK) because they're not even available for use in OrderBy. ... View more
