How to use select into a local variable in SYBASE ASE -


i using sybase ase 15.0.3. , want use type of logic, gives me error.

begin declare  @b int, @c int  select      @b = count(my_id)         some_table       (some_condition);   select      @c = count(my_sales)         some_table       (some_condition);   insert my_table (new_id, new_sales) value (@b, @c);  end;

and use these variables insert value table.

error: "attemp insert null value "new_id", table "my_table" column doesn't allow nulls. update fails"

you may have prepare sql statement before executing doing like:

 select @sql='insert my_table (new_id, new_sales) values ('+convert(varchar(10),@b)+','+convert(varchar(10),@c)+')'  exec @sql
