I'm ttrying to use the ContentQueryManager to find out the rate of
change of entries into one of my tables... I am using the following
query:
private ContentQueryManager<Venue> mVenueManager = new
ContentQueryManager<Venue>(mDatasource, Venue.class);
NewVenuesThisWeek = mVenueManager.count
(mVenueManager.getCountQuery().where("creation_dt", "<", "CAST ('1
week' AS INTERVAL)"));
I get back a syntax error from the postgres driver -- notice that
the single quotes around 1 week have been turned into double
quotes, oddly however the error from the low level driver shows the
correct quoting; I tried a few variations of quoting the single
quotes but the quotes got multiplied ''' turns into '''' in the
compiled query, etc ...
(I've tried the query select count(*) from venue where
creation_dt < CAST ('1 week'as INTERVAL); by hand in phpPgAdmin
and it returns the expected results)
What am I missing?
_DHMS
Error while executing the SQL 'SELECT count(*) FROM venue WHERE
creation_dt = 'CAST (''1 week'' AS INTERVAL)''.
