Add system.errors table Contains error codes with number of times they have been triggered. Columns: - `name` ([String](../../sql-reference/data-types/string.md)) — name of the error (`errorCodeToName`). - `code` ([Int32](../../sql-reference/data-types/int-uint.md)) — code number of the error. - `value` ([UInt64](../../sql-reference/data-types/int-uint.md)) - number of times this error has been happened. Example ``` sql SELECT * FROM system.errors WHERE value > 0 ORDER BY code ASC LIMIT 1 ┌─name─────────────┬─code─┬─value─┐ │ CANNOT_OPEN_FILE │ 76 │ 1 │ └──────────────────┴──────┴───────┘ 2020-10-28 22:00:04 +00:00			`#!/usr/bin/env bash`
