Обсуждение: Driver updates for 7.1
Unfortunately my understanding of the ODBC drivers internals is not such that I'm confident to do these mods myself (or my C for that matter!), but I've noticed a couple of things that probably should be updated for 7.1: 1) SQLGetInfo SQL_MAX_ROW_SIZE returns BLKSZ which is defined as 4096. With Toast in 7.1 presumably this is now incorrect? 2) SQLGetInfo SQL_MAX_STATEMENT_LEN currently returns MAX_QUERY_SIZE which is defined as 2* BLKSZ. Again, incorrect for 7.1 (and 7.0.x if I remember correctly)? 3) SQLGetInfo SQL_OUTER_JOINS currently returns 'N'. Should be 'Y' for 7.1? As the driver now claims to conform to ODBC v2.50, does SQLGetInfo SQL_OJ_CAPABILITIES also need to be implemented? Also, what with these and other recent updates such as referential integrity violation reporting, not to mention the recent confusion on the interfaces list as to what is the most up-to-date driver, perhaps the version number should be updated in psqlodbc.rc *and* psqlodbc.h. Regards, Dave.
OT Good to know someone else migrated to the list... was starting to think I was alone.

Yeah, me too. It does make me wonder if I need to post to interfaces to enure that messages get seen, or stay away from interfaces in the hope that more people will follow!

If it makes you feel any better, I'm here too ;)
IMHO, if ppl were to answer questions on -interfaces by redirecting ppl to
the proper lists, the original author would "get the idea" and follow his
message ...
Basically, reply, get rid of pgsql-interfaces@postgresql.org, change it to
pgsql-{jdbc,odbc}@postgresql.org, include the original author it in and
respond that way ...

I would post to JDBC with a blind CC to interfaces, mentioning the jdbc list.

Dave, did you fix all of these?

If you apply all three patches I submitted yesterday then yes, including SQL_OJ_CAPABILITIES. There is still a restriction on query size though as MAX_MESSAGE_LEN is used to define the message buffer length in a number of places. I've increased it from 8192 to 65536 which should be big enough for most people (i'd have thought), but I think a fair bit of work, beyond my expertise would be required to remove the limit completely.
