> ConvertJSONToSQL Statement Type provides fixed options :
> UPDATE,INSERT,DELETE.
> Usually, it can meet our needs. But in actual application,I think It's not
> flexible enough.
> In some cases, we need to dynamically indicate the Statement Type.
> For example,the data from CpatureChangeMysql owns the attribute of
> statement type（cdc.event.type, we need to convert the data to sql(DML)
> orderly; And we now have to use RouteOnAttribute to transfer data to three
> branches , Build SQL statement separately ,finally,we have to use
> EnforceOrder to ensure the order of SQL statements.
> But it will be easy if ConvertJSONToSQL supports dynamical Statement Type .
> It is easy to implement this feature just like PutDatabaseRecord.
> In practice, I did use PutDatabaseRecord instead of ConvertJSONToSQL.
