parameters

问题 I want to write a generic logging snip-it into a collection of stored procedures. I'm writing this to have a quantitative measure of our front-user user experience as I know which SP's are used by the front-end software and how they are used. I'd like to use this to gather a base-line before we commence performance tunning and afterward to show the outcome of tunning. I can dynamically pull the object name from @@PROCID, but I've been unable to determine all parameters passed and their values

问题 I have an android application that requests data from my mysql database. This works fine but when I try to send a parameter for how many items to retrieve I get nothing. This is my java code: result = ""; client = new DefaultHttpClient(); post = new HttpPost("http://www.XXX.XXXX.XX/XX.php"); nameValuePairs = new ArrayList<NameValuePair>(); nameValuePairs.add(new BasicNameValuePair("itemsToGet", itemsToGet)); try { post.setEntity((new UrlEncodedFormEntity(nameValuePairs))); response = client

问题 Previously I asked How to make a function which receive a function as param in C language. I get an answer Link to the question but this solution is based on the parameters of argument's function. I mean: int functionToPassAsParameter (int arg1, int arg2){ // do something } int functionWhichReceiveFunction (int (*f)(), int arg1, int arg2){ // do something f(arg1, arg2); // do something } // How to call the function functionWhichReceiveFunction (&functionToPassAsParameter, 1, 2); I would like

问题 According to the C++ Standard, function parameter's name is parsed by a declarator-id , and a declarator-id can also be a qualified name. That means, the following code is perfectly valid (if I've understood the relevant sections from the Standard correctly): template<class T> struct Sample { int fun(int T::count); //T::count is qualified variable name }; My question basically is, why would anyone write such code? In what situations, the use of qualified name (in function parameter-list) can

问题 I am trying to use the built-in Report Viewer control to generate my custom reports. Crystal Reports is heavy and doesn't work on all client computers therefore I'm giving the microsoft report build a try. The goal of this report is to print a list of all programs. They aregotten from the database and stored in a list like so: Private Function ProgramDataset() As DataSet Dim ds As DataSet = New DataSet("Programs") Dim allPrograms As List(Of clsProgram) = clsProgram.GetAll() 'Build datatable

问题 I have a route like this: match '/:search/:page', :to => 'search#create' and in my form: <%= form_for :search, :url => {:controller => 'search', :action => 'create', :page => 1, :search => ???} do |f| %> I need to pass something to :search but I want it to be the value that is submitted with the form. What do I do? 回答1: There is no straight way to do that as form with url (action) must be rendered before user types anything into search. So you need initial value, but it may not make sense

问题 In C# Asp.Net I need to pass my repeater occurrence index into a Javascript function when OnClientClick is depressed from an ASP button. Here is my code <asp:Button ID="btnGetNewQuote" Text="Get New Quote" class="pcbutton" runat="server" OnCommand="GetNewQuote" CommandArgument ='<%# Container.ItemIndex %>' OnClientClick="return getNewQuote(<%# Container.ItemIndex %>) /> If I hard code ....OnClientClick="return getNewQuote(0)"> it works and the JS gets invoked, but as soon as I put the #

问题 I've created an SSIS project, thinking it will be deployed in Project Deployment mode. A Lot of my packages have 2 Parameters (called P_OdsTbl and P_SrcEtl ), and whenever I used Execute package task I bound the Child Parameters to the Parent Parameters. I've since discovered that the project would be deployed in Package Deployment mode, which means I need to change the Parameters to Variables ( V_OdsTbl and V_SrcEtl ) and set their values with Variable Configurations. I have many references

问题 I have a problem with a question mark parameter in a prepared statement using PDO. My Query class looks like this ( for now, I'm still adding functionality like data limits, custom parameters filtering and automatic detection of supported statements for the driver being used ): // SQL query class Query { public $attributes; // constructor for this object public function __construct() { if ($arguments = func_get_args()) { $tmp = explode(" ", current($arguments)); if (in_array(mb_strtoupper

问题 edit see the bottom for how I fixed this I've written my own Keras layer, whose build method is as follows: class Multed_Weights(Layer): def __init__(self, input_dim, output_dim, **kwargs): self.output_dim = output_dim self.input_dim = input_dim super(Multed_Weights, self).__init__(**kwargs) def build(self, input_shape): # Create a trainable weight variable for this layer. self.kernel = self.add_weight(name='kernel', shape=(self.input_dim, self.output_dim), initializer=RandomNormal(mean=0.,
