I think I am almost there....
don't laugh but here is what I am doing...
String theSQL = "SELECT sum(c_amount_of_time) as c_amount_of_time FROM t_e_time
et WHERE c_user_id = '" +
userList.objectAtIndex(i).primaryKey() + "' AND " +
"et.c_job_id IN (SELECT id FROM t_job WHERE c_project_id = '" +
theProject().primaryKey() + "')";
NSArray<?> result;
result = EOUtilities.rawRowsForSQL(timeListEC, "TheWorkTrackerModel", theSQL,
new NSArray<Object>(new String[] {"c_amount_of_time"}));
NSLog.out.appendln(" **************** result = " + result);
my log shows..... **************** result = ({c_amount_of_time = 12;
})
ouch.. If I run the above SQL in the terminal, I get:
LOG: statement: select sum(c_amount_of_time) from t_e_time et where c_user_id
= 3 and
et.c_job_id IN (SELECT id FROM t_job WHERE c_project_id = 16);
sum
-------------
12.50000000
(1 row)
what happened to the decimal...??
