# ClickHouse Common Errors
## Overview
Quick reference for the most common ClickHouse errors with real error codes,
diagnostic queries, and proven solutions. The three highest-frequency errors are
inline below; the full catalog of 10 errors plus system-table diagnostics lives
in [references/error-reference.md](references/error-reference.md).
## Prerequisites
- Access to a ClickHouse endpoint — either the native `clickhouse-client` or the
HTTP interface (`curl` against `:8123`).
- Permission to read the `system.*` introspection tables (`system.parts`,
`system.processes`, `system.query_log`, `system.columns`, `system.replicas`).
