Обсуждение: dblink: enable parameters
Hello I know so dblink is "deprecated" interface - but it has necessary functionality still - it support a writable statements. Very simple enhancing should be enable params to query - it's analogy to USING clause in EXECUTE statement. Regards Pavel Stehule

It would be nice to add support for SQL/MED "passthrough mode"... That would allow you to do any queries/updates to foreign servers. It wouldn't sound very difficult at first glance, though I'm not sure what it would mean to our parser, for example. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com

I think passthrough mode is almost impossible or has very limited usage because we cannot pass query texts that our parser doesn't accept; we cannot support foreign-table-specific queries. > On 22.11.2011 06:55, Pavel Stehule wrote: >> I know so dblink is "deprecated" interface - but it has necessary >> functionality still - it support a writable statements. So, "dblink on FDW connection" seems to be a possible solution. We pass a query as a form of a plain text. -- Itagaki Takahiro
