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 │
└──────────────────┴──────┴───────┘
This patch adds errorCode() function that will return macro name by the
exception code, useful for analyzing query_log and similar.
Later some descriptions can be added.
v2: replace hana::map/fusion::vector with external script
v3:
- use binary cmake dir for .sh
- use jump table over suboptimal std::unordered_map (with very poor hash
function for int -- std::hash)
- cleanup errorCodeToName (drop extra templates and headers)
- rename errorCode -> errorCodeToName
- fix arcadia build (by not providing those helpers there)
- fix build on CI, by using CMAKE_CXX_COMPILER for parsing the file
