Finding sum based on the condition in Sql Server 2008 -


i have these columns in table

person      agent     unit        bsp            discount 

578           0      000023      32689525       0.1 578           1      000025      17589656       1 579           0      000021      32689525       0.1 579           0      000020      17589656       1 581           0      000022      32689525       0.1 583           0      000024      17589656       1 578           11     000023q     32689525       0 578           12     000025a     17589656       0 

actually have calculate incentive person. in case of above 578. since has booked total 4 units out 3 brokers , 1 individual. broker part incentive 2500 inr per unit 3*2500 = 7500. comes discount part. see points below:

conditions:

  1. if no discount has been given, 1% of bsp allocated incentive sales person.

  2. if discount given booking between .1% 1%, .75% of bsp allocated incentive sales person.

  3. if discount given booking between 1 .1% 2%, .50% of bsp allocated incentive sales person.

  4. if discount given booking between 2% , above, .25% of bsp allocated incentive sales person.

in above tables clear 578 has booked 4 units, 2 discounts 2 without discounts.

so incentive calculated :

  var incentive = total_no_of_units_booked_with_agent * 2500;  // since there might possibility more 1 units can // booked sales person.no have find if there discount  // applied there, if there, extract incentive each unit  //and total using above condition. table shown have //since has 4 records    incentive = incentive + (.75% of bsp)+ (.75%of bsp)+(1% of bsp)+(1%of bsp)  

for conditional sum, use sum case statement inside enforce conditions.

select   person,   sum(case when discount  = 0.00 0.0100 * bsp            when discount <= 0.01 0.0075 * bsp            when discount <= 0.02 0.0050 * bsp                                  else 0.0025 * bsp end       +       case when agent <> 0       2500.0                                  else    0.0       end)  incentive   yourtable group   person
