---------------------------------
Summary: Add SHIFTRIGHT supported in SQL & Table API
Key: FLINK-26946
URL: https://issues.apache.org/jira/browse/FLINK-26946
Project: Flink
Issue Type: Sub-task
Components: Table SQL / API
Reporter: dalongliu
Fix For: 1.16.0
Returns a bitwise signed integral number right shifted by {{n}} bits.
Syntax:
{code:java}
shiftright(expr, n){code}
Arguments:
* {{{}expr{}}}: An INTEGER or BIGINT expression.
* {{{}n{}}}: An INTEGER expression specifying the number of bits to shift.
Examples:
The result type matches {{{}expr{}}}.
When {{expr}} is negative (that is, the highest order bit is set) the result
remains negative because the highest order bit is sticky. When {{n}} is
negative the result is 0.
