--------------------------------

             Summary: Bug of 'JoinRelNode Convert SqlStatement'
                 Key: CALCITE-3207
                 URL: https://issues.apache.org/jira/browse/CALCITE-3207
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Xurenhe


Hi all
I have a problem when using calcite, which is 'relnode convert sql statement'

example:
```
Input relNode: 
LogicalProject(name=[$1], score=[$4])
 LogicalJoin(condition=[AND(=($0, $3), LIKE($0, 'lucy'))], joinType=[left])
 LogicalTableScan(table=[[db0, user_table]])
 LogicalTableScan(table=[[db0, score_table]])


Expect output sql statement: 
select name, score
from user_table
left join on score_table
and name like 'lucy'

```
this relNode cannot convert sql statement.

I try to debug it, `org.apache.calcite.rel.rel2sql.SqlImplementor#convertConditionToSqlNode` may forgot to handle this case, which sqlKind is SqlKind.LIKE.

If it is a bug, I am willing to fix it.

Thanks.
