--------------------------------
Summary: wrong definition of Replace planner expression
Key: FLINK-13353
URL: https://issues.apache.org/jira/browse/FLINK-13353
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.9.0, 1.10.0
Reporter: Louis Xu
Fix For: 1.10.0
Replace definition in stringExpression.scala has another constructor with 2
arguments.
According to source code, the args' meaning are str, begin. And it call other
constructor with 3 args adding the 3rd arg which is the length of str.
But its expectTypes is (String, String, String), but actually is (String, int,
int).
So I think the 2 args defined constructor means search and replacement is ""
default, not begin and length of str.
