[jira] [Commented] (CALCITE-3732) Implement bit functions and
operators
[ https://issues.apache.org/jira/browse/CALCITE-3732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17015117#comment-17015117 ]
Stamatis Zampetakis commented on CALCITE-3732:
----------------------------------------------
As you said bitwise and, xor, and or are already implemented so what exactly are you proposing? The syntactic sugar for them (&, ^, |)?
Are you planning to work on this?
> Implement bit functions and operators
> -------------------------------------
>
> Key: CALCITE-3732
> URL: https://issues.apache.org/jira/browse/CALCITE-3732
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.21.0
> Reporter: hailong wang
> Priority: Major
> Fix For: 1.22.0
>
>
> Bit function is non-standard operators, but all db has implemented, such as mysql, postgresql.
> Calcite has implemented BIT_AND, BIT_OR in https://issues.apache.org/jira/browse/CALCITE-2770, BIT_XOR in https://issues.apache.org/jira/browse/CALCITE-3591. BIT_COUNT is in progress https://issues.apache.org/jira/browse/CALCITE-3697, BIT_NOT(~) is in progress https://issues.apache.org/jira/browse/CALCITE-3592.
> So I think we should also implement Bitwise AND(&), Right shift(>>), Left shift(<<), Bitwise XOR(^), Bitwise OR(|). And data types support tinyint, smallint, int, bigint like before.
