before identical sql call stored procedure each row without using cursor let me clarify question: the stored procedure have side effects. in fact, it's side effects, results of each call influence further processing. think of this: table contains rule definitions, , proc executes rules literally rbar, making changes table. under conditions not see how set operation possible, cross apply can't used because of side effects, it's not needed, since i'm not joining rule table results. if solution rbar, should still try avoid using cursor? using while read top 1 key > @key better solution? why? the more searched, more came conclusion fast_forward read_only cursor simplest , fastest solution. cursors inherently bad no. cursors misused, , tend leapt upon people new sql because they're procedural background , haven't heard of "set-based". cursors have place, , if you've assessed available approaches , concluded cursors fit, ...

how pattern-matching type of argument works in f#? for example i'm trying write simple program calculate square root if number provided or return it's argument otherwise. open system let my_sqrt x = match x | :? float f -> sqrt f | _ -> x printfn "enter x" let x = console.readline() printfn "for x = %a result %a" x (my_sqrt x) console.readline() i error: error fs0008: runtime coercion or type test type 'a float involves indeterminate type based on information prior program point. runtime type tests not allowed on types. further type annotations needed. since sqrt works float check float type, guess there better solution - check if input number (in general) , if so, cast float? the problem here type of x string . adding comes console.readline , kind of information stored in string possible determine @ runtime. means can't use neither pattern matching, nor pattern matching coercion here. ...
