# E2203

> BigQuery target — Partition column has the wrong type

The partition column is not `INT64`. `FLOAT64`/`NUMERIC` lose precision above 2^53 (Solana slot
numbers exceed this) and non-integer types break `RANGE_BUCKET` pruning, so reorg-cleanup `BETWEEN`
predicates become inexact.

**Fix** — type the partition column as `INT64`.
