Hello, I have a question about searching piavg.
When I execute the mext SQL statement, I got "#ERROR" in the "timestep" column.
SELECT * FROM piarchive..piavg WHERE tag = 'sinusoid' AND time BETWEEN '2011/3/1' AND '2012/3/1' AND timestep = '1mo'
When I specifiy "24h" at timestep, I got "#ERROR" again.
But, when I specify the value less than "23h", I don't get any "#ERROR".
I can't specify the value greater than "24h" at timestep when I search piavg table, can I?
