Hi all! I'm developing an algorithm with PL/PGSQL using statistical operations from a table. I have several differences between expected results and the results generated by the function. I want to know if there are differences in arithmetic operation sintax or if there's any special arithmetical operators precedence between pl/pgsql and other languages. My code looks like this: FOR iterator1 IN SELECT period, AVG(col1) AS avg_col1, STDDEV(col1) AS dev_col1, AVG(col2) AS avg_col2, STDDEV(col2) AS dev_col2 FROM scheme.table GROUP BY period ORDER BY period LOOP FOR iterator2 IN SELECT period, id, col2, col1 FROM scheme.table WHERE col1 IS NOT NULL LOOP IF grav = 0 THEN _standata := (iterator2.col1 - iterator1.avg_col1) / iterator1.dev_col1; ELSE _standata := (iterator2.col2 - iterator1.avg_col2) / iterator1.dev_col2; END IF; UPDATE scheme.table SET standata = _standata WHERE id = iterator2.id AND period=iterator2.period; _standata := 0.0; END LOOP; END LOOP; Thanks! -- View this message in context: http://www.nabble.com/PL-PGSQL-arithmetic-errors-tp22795583p22795583.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
