Generating Unique No Based On Certain Data

Hi,

I have the following tables :




Code Block
Create Table #Request ( [requestid] int , [customername] Varchar(30) , [stateno] nvarchar(5) , [cityno] int , Callid int, UniqueNo int);

Create Table #Call(Callid int,Calltype int,callDetailid int ) // CallType 1=New 2=Change 3=Delete

Create Table #CallDetail(callDetailId int,empid int)




The tables are populated in the following order: One row for CallDetail, One for Call and one for Request and so on

I have to generate a UniqueNo - Per empid, Per StateNo, Per CityNo, Per CallType and insert into #Request table along with the other data. How do I do this?

SAMPLE DATA



Code Block
Insert into #CallDetail(12123,1)
Insert into #CallDetail(53423,1)
Insert into #CallDetail(6532,1)
Insert into #CallDetail(62323,1)
Insert into #CallDetail(124235,1)
Insert into #CallDetail(65423,2)
Insert into #CallDetail(56234,2)
Insert into #CallDetail(2364,2)
Insert into #CallDetail(34364,2)
Insert into #CallDetail(85434,2)

Insert Into #Call(111,1,12123)
Insert Into #Call(112,1,53423)
Insert Into #Call(114,1,6532)
Insert Into #Call(123,2,62323)
Insert Into #Call(134,1,124235)
Insert Into #Call(143,2,65423)
Insert Into #Call(145,1,56234)
Insert Into #Call(154,2,2364)
Insert Into #Call(185,1,34364)
Insert Into #Call(195,1,85434)

Insert Into #request Values('324234','Jack','SA023',12,111,0);
Insert Into #request Values('223452','Tom','SA023',12,112,0);
Insert Into #request Values('456456','Bobby','SA024',12,114,0);
Insert Into #request Values('22322362','Guck','SA024',44,123,0);
Insert Into #request Values('22654392','Luck','SA023',12,134,0);
Insert Into #request Values('225652','Jim','SA055',67,143,0);
Insert Into #request Values('126756','Jasm','SA055',67,145,0);
Insert Into #request Values('786234','Chuck','SA055',67,154,0);
Insert Into #request Values('66234','Mutuk','SA059',72,185,0);
Insert Into #request Values('2232362','Buck','SA055',67,195,0);




EXPECTED OUTPUT will be (See the last column for unique nos). :



Code Block
Insert Into #request Values('324234','Jack','SA023',12,111,1);
Insert Into #request Values('223452','Tom','SA023',12,112,2);
Insert Into #request Values('456456','Bobby','SA024',12,143,1); // Calltype = 1 empid= 1, but state is different, hence unique id is 1
Insert Into #request Values('22322362','Guck','SA024',44,114,1);
Insert Into #request Values('22654392','Luck','SA023',12,123,3);
Insert Into #request Values('225652','Jim','SA055',67,143,1);
Insert Into #request Values('126756','Jasm','SA023',69,134,1);
Insert Into #request Values('786234','Chuck','SA023',72,145,2);
Insert Into #request Values('66234','Mutuk','SA059',72,185,1);
Insert Into #request Values('2232362','Buck','SA055',67,195,2);





Please note that this will not be run as a batch query, but the no. has to be generated and inserted into #record table in realtime. I have given bulk of records for understanding of the problem

Plz help. I am stuck from 2 days on this :
