batch file - Start worker job from where it was left off with php resque? -


In the process, batching queries in a php job is curious to me if there is a way to leave where to leave the job.

psdeuo code 

  function display () {$ batch_limit = 0; While ($ batch_limit & lieutenant; 20) {result = gatestream ($ batch_limit); Dostuff (result); $ Batch_limit + = 2; } Function getstuff ($ batch_limit) {$ result = $ con- & gt; Query ("Select * To $ Latch $ batch_limit, 2); $ Result Return;}

For example if

'Limited from the table * 4, 2 'Select

Can I choose and execute anyway

' Table LIMIT 6, 2 '

Write the current limit in a simple key / value table and execute .

I have a table for this kind of information, because it is often The key is VARCHAR and the value is integer.

Then enter your batch limit at the beginning of each call GetStuff () < / P>

getstuff ($ batch_limit) {$ con- & gt; query ("UPDATE keyvaluetable SET value = $ batch_limit WHERE key = 'batch_limit'"); $ result = $ Con- & gt; Query ("SELECT * FROM table LIMIT $ batch_limit, 2"); Return $ result;}

and select it at the beginning of your display () 

  Function Performance () {$ result = $ conn- & gt; Query ("Questions before receiving value"); If ($ result) {$ batch_limit = $ result; } And {$ batch_limit = 0; } While ($ batch_limit & lt; 20) {result = getstuff ($ batch_limit); Dostuff (result); $ Batch_limit + = 2; }

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
