Case

Goal: Handle drizzle-orm SQLite column modes, timestamp default precision loss, null comparison vs isNull, and onConflict returning shapes HOW
Packages: drizzle-orm 0.45.2
Environment: node
Created: 2026-08-16T06:23:33Z

assert integer column with mode timestamp truncates/floors Date millisecond precision to whole seconds in SQLite, whereas mode timestamp_ms preserves millisecond precision
assert SQLite DEFAULT (CURRENT_TIMESTAMP) stores a text string in integer column, which Drizzle's mode timestamp mapper deserializes as Invalid Date (NaN), whereas DEFAULT (unixepoch()) or .$defaultFn() deserializes as a valid Date
assert eq(column, null) produces SQL column = ? with param null matching zero rows in SQL three-valued logic, and isNull(column) is required to query null rows
assert passing an empty array to inArray compiles to SQL 'where false' and notInArray compiles to 'where true' rather than throwing a SQL syntax error
assert onConflictDoNothing().returning() on a conflicting insert returns an empty array [] rather than the existing row
assert db.query is an empty object {} and tables are undefined on db.query unless an explicit schema option is passed into drizzle()
