SQLStatistics problem

От

Greetings,

I am having a problem with SQLStatistics.  I am using Hiroshi Inoue's
latest ODBC DLL's, PostgreSQL 8.1.2, all on Windows XP.

I issued the following SQL statements:


ALTER TABLE ONLY rights
    ADD CONSTRAINT rights_id_key UNIQUE (id);


CREATE UNIQUE INDEX blake ON rights (deny_flag);

When I do a dump of the database the two statements create different
results as I would expect.  By "different results" I mean the dump uses
different commands to re-create each of those things.  One is a constraint
and the other an index.

When I use ODBC SQLStatistics I get back records for each of those statements
but there is no way to distinguish the constraint from the index.

Any help would be appreciated.

Sincerely,

Blake McBride

One way seems to be to check the existence of pg_constraint data
whose name = the index_name.
