Subject SqlSpecialOperator.createCall method is overridden only for some nodes
Date Thu, 02 Feb 2017 16:09:57 GMT
Hi all,

I have noticed that for example, for SqlExplain
SqlSpecialOperator.createCall [1] method is overridden but for SqlInsert
[2] it is not. Thus in case with SqlExplain OPERATOR createCall returns
SqlCall instance that can be cast to SqlExplain but in case of SqlInsert
createCall returns SqlCall that can be cast only to SqlBasicCall (and I
can't take advantage of SqlInsert methods).

So I wanted to ask is there is any particular reason why some nodes do have
createCall method overridden and some don't? And in case of SqlInsert
should it be fixed or not?


Kind regards
