I'm trying to move code across from my Perl program over to MS SQL Server. But the following TSQL code: 

SELECT
SUM(A.Person_count/(B.Person_count*E.Number_of_years)/A.Total_pop*C.Pe
+rson_count))*1+(sqrt((SUM((A.Person_count/(B.Person_count*E.Number_of
+_years)/A.Total_pop)*(A.Person_count/(B.Person_count*E.Number_of_year
+s)/A.Total_pop)*C.Person_count))/(SUM(C.Person_count)))*(((SUM(C.Pers
+on_count)+1))*(1-1/(9*((SUM(C.Person_count)+1)))+1.96/(3*sqrt((SUM(C.
+Person_count)+1))))^3-(SUM(C.Person_count))))*1
 FROM        ************ A, ****************** B, ************** C, *
+************ E

Gives me the error message: 

Invalid operator for data type. Operator equals boolean XOR, type equa
+ls float.

Can anyone please point out the problem with this?
