-

i'm getting following error:

mysql error

1064 - have error in sql syntax; check manual corresponds mysql server version right syntax use near 'distinct r.roomtype roomtype , i1.meal_plan mealplan , i1.`bed_t' @ line 3

my code is

select      distinct h.`hotelname` `hotelname` ,      distinct r.`roomtype` `roomtype` ,      i1.`meal_plan` `mealplan` ,      i1.`bed_type` `bedtype` ,      i1.`roomrate` `roomrate` ,      i1.`pax` `pax` ,      i1.`childrate` `childrate` ,      i1.`childrate1` `childrate1` ,      i1.`childrate2` `childrate2` ,      i1.`childrate3` `childrate3` ,      p.`profitmarkup_type` `profit_type` ,      p.`applyprofit_val_room` `applyprofit_val_room` ,      p.`applyprofit_val_bed` `applyprofit_val_bed`  `hoteldetails` h  inner join `roomdetails` r      on h.`hotelname` = r.`hotelname`  inner join `inventorypolicy` i1      on i1.`hotel_name` = h.`hotelname`      , i1.`room_plan` = r.`roomtype`      , i1.`bed_type`=r.`bedtype`      , i1.`meal_plan`=r.`mealplan`      , i1.`suppliername`=h.`supplier`  inner join `profitmarkup` p      on p.`hotel_name` = h.`hotelname`      , p.`suppliername` = h.`supplier`  h.`active`='1'      , h.`country`='mal'      , h.`city`='kl'      , h.`show2web`='1'      , h.`expiry_date` >= 11/09/2014      , i1.`inventory_status`='1'      , p.`markup_status` = '1'      , 20140911 between ((i1.`date1`)+(i1.`month1`*100)+(i1.`year1`*10000)) , ((i1.`date2`)+(i1.`month2`*100)+(i1.`year2`*10000))      , 20140911 between ((p.`date1`)+(p.`month1`*100)+(p.`year1`*10000)) , ((p.`date2`)+(p.`month2`*100)+(p.`year2`*10000))

i dont know how fix this. appreciated.

as can learn documentation of select mysql statement, distinct can placed before field or expression selected. automatically forces single instance of in query.

and somewhere down road there sentence says everything:

distinctrow synonym distinct.
