Re: Issue with Save and Release points

Thanks Hiroshi,

Is there anywhere I can do some reading up about the SQLStatistics() function and how to cache its results so that ODBC doesn’t need to run these repeatedly for each statement? Will I be able to call SQLStatistics() from VBA?

On a separate note – another way to tackle this might be to issue bulk insert statements but my approach so far has been to issue bulk statements using the postgres syntax from vba

i.e. to populate a string with an insert statement like

INSERT INTO tblA(field1, field2) VALUES

(1, 999),

(2, 888);

And to issue via the driver using following:

ThisDB.Execute strSQL, dbFailOnError

ThisDB is created using :

Set ThisDB = OpenDatabase("", False, False, DBName)

But I keep getting a syntax error for missing ; even though this exact query works on pgAdmin

Regards

Dan

Hi Daniel,

Unfortunately it needs an implementation change.
If you hope, I would try to cache the result of SQLStatistics().

Hi Hiroshi,

 

This is repeated about 2 times for each INSERT statement, how would I go about changing the driver to cache the result? (I tried switching on connection pooling for the Postgres Unicode driver with a 60 second timeout but those queries didn’t reduce).

 

Regards

Dan

Hi Daniel,

Looks like the log is a part of SQLStatistics call.
If SQLStatistics calls for a table are repeated, maybe the driver had better cache the result.

Hi Hiroshi,

 

Please find attached the mylog from when the job runs (have only switched on for 1 run and then switched off due to the time cost from this)

Hi Daniel,

Doesn't your connection string contain 'Protocol=7.4-2' option?
If so, please change it to 'Protocol=7.4-1'.

Thanks Takayuki,

 

We’ve tried with Transaction but are still seeing save points and release points in the postgres logs. Also on executing the same query on localhost (from my laptop) am getting slow performance (around 4 records per second).

 

We don’t see same performance drawback on inserting directly on the client
