Dawid Wysakowicz reassigned FLINK-32815: ---------------------------------------- Assignee: Hanyu Zheng > Add HASHCODE support in Table API > --------------------------------- > > Key: FLINK-32815 > URL: https://issues.apache.org/jira/browse/FLINK-32815 > Project: Flink > Issue Type: Improvement > Reporter: Hanyu Zheng > Assignee: Hanyu Zheng > Priority: Major > Labels: pull-request-available, stale-major > > *This is an implementation of HASHCODE internal function* > The {{hashcode}} function generates a hash code for a given input value, > including support for computing hash values of binary data types. It creates > a unique integer that represents the value passed to the function. > *Brief change log* > * {{HASHCODE}} for Table APIĀ > *Syntax:* > {code:java} > HASHCODE(value){code} > *Arguments:* > * value: the value to be hashed. > *Returns:* The function returns a unique integer representing the hash code > of the value. If the input argument is NULL, the function returns NULL. > Because it is an internal function, so it will not support sql anymore. > *see also:* > Java: > [https://docs.oracle.com/javase/8/docs/api/java/lang/Object.html#hashCode--] > Python: [https://docs.python.org/3/library/functions.html#hash] > C#: [https://docs.microsoft.com/en-us/dotnet/api/system.object.gethashcode] > SQL Server: > [https://docs.microsoft.com/en-us/sql/t-sql/functions/checksum-transact-sql] > MySQL: > [https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_md5] > PostgreSQL: [https://www.postgresql.org/docs/current/pgcrypto-hash.html] > Oracle: > [https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/ORA-HASH.html] > Google Cloud BigQuery: > [https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#farm_fingerprint] > AWS Redshift: [https://docs.aws.amazon.com/redshift/latest/dg/MD5.html] -- This message was sent by Atlassian Jira (v8.20.10#820010)
