[feature](functions) impl scalar functions normal_cdf,to_iso8601,from_iso8601_date (#40695) #41049
Conversation
…_iso8601_date (apache#40695) Added three functions: `normal_cdf`, `to_iso8601`, `from_iso8601_date` 1. `normal_cdf(mean, sd, v) → double` : Compute the Normal cdf with given mean and standard deviation (sd): P(N < value; mean, sd). The mean and value must be real values and the standard deviation must be a real and positive value (all of type DOUBLE). 2. `to_iso8601(DATE/DATETIME) → string` For `DATE` type, it will be converted to `YYYY-MM-DD`. For `DATETIME` type, it will be converted to `YYYY-MM-DDThh:mm:ss.xxxxxx`. 3. `from_iso8601_date(string) → DATE` Convert iso8601 string to `DATE` type. The supported iso8601 string formats are as follows: a. Year : YYYY b. Calendar dates : YYYY-MM-DD , YYYYMMDD , YYYY-MM c. Week dates : YYYY-Www , YYYYWww , YYYY-Www-D , YYYYWwwD d. Ordinal dates : YYYY-DDD , YYYYDDD You can refer to this [document](https://en.wikipedia.org/wiki/ISO_8601) to understand what these formats mean Please note that: a. Each date and time value has a fixed number of digits that must be padded with leading zeros. b. The range of YYYY is 0001-9999. outside these rules, the correctness of the results is not guaranteed. For illegal values, the result is NULL.

Thank you for your contribution to Apache Doris. Since 2024-03-18, the Document has been moved to doris-website. |

Proposed changes
Added three functions:
normal_cdf,to_iso8601,from_iso8601_datenormal_cdf(mean, sd, v) → double: Compute the Normal cdf with given mean and standard deviation (sd): P(N < value; mean, sd). The mean and value must be real values and the standard deviation must be a real and positive value (all of type DOUBLE).to_iso8601(DATE/DATETIME) → stringForDATEtype, it will be converted toYYYY-MM-DD. ForDATETIMEtype, it will be converted toYYYY-MM-DDThh:mm:ss.xxxxxx.from_iso8601_date(string) → DATEConvert iso8601 string toDATEtype.The supported iso8601 string formats are as follows:
