### Is your feature request related to a problem or challenge? While working on replacing GetFieldAccess with `get_field` function, I got the [name checking error](https://github.com/apache/datafusion/blob/b21bf9e8527de82e901c3a61127d63779f230163/datafusion/physical-expr/src/equivalence/projection.rs#L70-L73) that due to the mismatch of separator in creating name. I found that most of the name built with single comma and space, so I think we should switch others to this format `.join(", ")`. Error is like ``` External error: query failed: DataFusion error: Internal error: Input field name SUM(get_field(CASE WHEN get_field(t2.struct(t1.time,t1.load1,t1.load2,t1.host), Utf8("c3")) IS NOT NULL THEN t2.struct(t1.time,t1.load1,t1.load2,t1.host) END,Utf8("c2"))) does not match with the projection expression SUM(get_field(CASE WHEN get_field(t2.struct(t1.time,t1.load1,t1.load2,t1.host),Utf8("c3")) IS NOT NULL THEN t2.struct(t1.time,t1.load1,t1.load2,t1.host) END,Utf8("c2"))). This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker [SQL] select t2."struct(t1.time,t1.load1,t1.load2,t1.host)"['c3'] as host, sum((case when t2."struct(t1.time,t1.load1,t1.load2,t1.host)"['c3'] is not null then t2."struct(t1.time,t1.load1,t1.load2,t1.host)" end)['c2']) from (select struct(time,load1,load2,host) from t1) t2 where t2."struct(t1.time,t1.load1,t1.load2,t1.host)"['c3'] IS NOT NULL group by t2."struct(t1.time,t1.load1,t1.load2,t1.host)"['c3'] order by host; ``` I got one with `t2.struct(t1.time,t1.load1,t1.load2,t1.host), Utf8("c3")` and another `t2.struct(t1.time,t1.load1,t1.load2,t1.host),Utf8("c3")`. That is why I think we should fix the separator. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
