Too many left parenthesis.

select cast(B1 as int)+cast(H1 as int)+cast(C1 as int)+cast(I1 as int) as [man] From Kanpur

B1, H1, C1, I1 should be declared in the database as INT data type columns. Then you would not have to use the CAST function. It is an unprofessional programming practice to store data in a database in a column that does not represent the type of data stored. INTs should be stored in INT data type. Dates should be stored in Date data types.
