php - Do PDO tokens need to match the bindValue 1:1? -

-

i have code

$query = 'insert table                   (foo, bar, baz)                   values                   (:foo, :bar, :baz)           on duplicate key update foo = :foo,                                   bar = :bar,                                   baz = :baz'; $stmt = $dbc->prepare($query); $stmt->bindvalue(':foo', $foo, pdo::param_str); $stmt->bindvalue(':bar', $bar, pdo::param_str); $stmt->bindvalue(':baz', $baz, pdo::param_str);  $stmt->execute();

its throwing error:

fatal error: uncaught exception 'pdoexception' message 'sqlstate[hy093]: invalid parameter number: number of bound variables not match number of tokens

obviously, have twice many token bound variables, have same number of unique tokens. question is, can each token used once? need rename second instance of each token work, or there way without doubling bindvalue statements?

it turns out can reuse tokens. error else entirely. if find in future wondering same thing, yes it's possible. error else. missed colon or in mess of tokens forgot add bindvalue one.

as noted barmar below, functionality may need pdo::attr_emulate_prepares enabled occur. use mysql has enabled default, can not speak truth of off top of head.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
