########## File path: docs/sql-ref-datetime-pattern.md ########## @@ -199,11 +231,15 @@ The count of pattern letters determines the format. - Number/Text: If the count of pattern letters is 3 or greater, use the Text rules above. Otherwise use the Number rules above. -- Fraction: Outputs the micro-of-second field as a fraction-of-second. The micro-of-second value has six digits, thus the count of pattern letters is from 1 to 6. If it is less than 6, then the micro-of-second value is truncated, with only the most significant digits being output. +- Fraction: Use `'S..S'` pattern for parsing and formatting fraction of second. + For parsing, the acceptable fraction length can be [1, `'S..S'`.length(<=9)] and with `[]` surrounded can be [0, `'S..S'`.length(<=9)]. Review comment: And we don't need to mention `[]`, as it's semantic is well defined and orthogonal to the second fraction. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
