Hi I have executed following SQL Statement : *sql>select product_id, sum(unit_sales),avg(unit_sales), max(unit_sales), min(unit_sales),sum(store_sales),avg(store_sales), max(store_sales), min(store_sales), sum(store_cost),avg(store_cost), max(store_cost), min(store_cost) from sales_fact_1997 group by product_id; It Gives following result: (In my table very large data there for i have given starting and ending rows of result set) +-----------+--------------+--------------------------+--------------+--------------+--------------+--------------------------+--------------+--------------+ | product_i | L1 | L2 | L3 | L4 | L5 | L6 | L7 | L10 |> : d : : : : : : : : :> +===========+==============+==========================+==============+==============+==============+==========================+==============+==============+ | 337 | 333644.7415 | 3.4849771407382648 | 6.9998 | 0.0001 | 1145678.6601 | 11.966812134157813 | 23.9986 | 0.0005 | | 1512 | 336475.1207 | 3.4816655356884185 | 6.9999 | 0.0001 | 1158967.1049 | 11.992375001552128 | 23.9995 | 0.0011 | | 963 | 333727.8589 | 3.4994427668141643 | 6.9997 | 0.0003 | 1139917.6212 | 11.953082033429096 | 23.9998 | 0.0008 | | 181 | 334323.6059 | 3.4942578847801946 | 6.9999 | 0.0003 | 1145948.0178 | 11.977131815046297 | 23.9980 | 0.0002 | | 1383 | 334298.1724 | 3.4923130291254028 | 6.9999 | 0.0002 | 1145319.9025 | 11.964814492708198 | 23.9992 | 0.0015 | | 1116 | 337661.6147 | 3.4923165958195015 | 6.9999 | 0.0003 | 1161142.4618 | 12.009292477789144 | 23.9996 | 0.0003 | | 488 | 336083.8006 | 3.5025147266948111 | 7.0000 | 0.0008 | 1149952.2337 | 11.984286735448883 | 23.9992 | 0.0004 | | 121 | 336465.6749 | 3.486221285215461 | 6.9999 | 0.0001 | 1154632.2251 | 11.963489116492081 | 23.9998 | 0.0001 | | 1338 | 337204.2797 | 3.478592072170585 | 7.0000 | 0.0001 | 1162678.8747 | 11.994170179601195 | 23.9996 | 0.0015 | | 910 | 338799.1540 | 3.4927387758889044 | 6.9999 | 0.0001 | 1166834.3104 | 12.029095683549643 | 23.9996 | 0.0001 | | 438 | 335488.9579 | 3.5050823580421069 | 6.9999 | 0.0002 | 1150602.4234 | 12.021129639032544 | 23.9982 | 0.0005 | | 1560 | 338661.5694 | 3.4991844580143199 | 6.9997 | 0.0001 | 1154747.3055 | 11.93130307492018 | 23.9994 | 0.0019 | +-----------+--------------+--------------------------+--------------+--------------+--------------+--------------------------+--------------+--------------+ 1560 tuples (3m 55s) !4 columns dropped! note: to disable dropping columns and/or truncating fields use \w-1 Hear, Monetdb gives only 9 column in result table and gives message 4 columns dropped as i show in following query it gives result of only yellow highlighted statement / columns result. Monetdb can not show blue highlighted part's result. **sql>select product_id, sum(unit_sales),avg(unit_sales), max(unit_sales), min(unit_sales),sum(store_sales),avg(store_sales), max(store_sales), min(store_sales), sum(store_cost),avg(store_cost), max(store_cost), min(store_cost) from sales_fact_1997 group by product_id; my question is that, Monetdb calculate result of all SQL statement or it does not calculate dropped column value. My Next Question How will I see this Dropped result? I hope you will give me proper guidance. My Monetdb version : MonetDB-11.11.07 * * * -- Regards, Swapnil K.
