sql - Variable not getting set by select -

-

I have an issue where a variable is not set with a selection statement.

A table variable @ contact (which is used to control a loop) and then is included in the real contract and contract line tables.

My selection is: 

  Select Top 1 @contract_id = c.contract_id, @account = ch.account, @service = cl.service, @model = Cl.model, @serial = cl.serial, @contract = ch.contract @ Contracts c inner in contractline cl C.contract_id = cl.contract_id Internal connected contactHard cl.contract = ch.contract where cl.contract_id = @contract_id

But when I do a select @contract_id, then return me a NULL , as all of my variables are

I Contract_ID = CLC with Contract_ID, a simple < Od> SELECT * is inserted C. CC contract = seed contract and it gives exactly 1 line with values ​​in all the right places, there is no vacancy in the selected values.

What have I done?

It seems that your WHERE block can be prevented from returning. You have mentioned that you have tested the same SELECT without setting the same, but the code you listed does not include this WHERE - so its not the same. Test your SELECT with WHERE and

dummy value (potential NULL ) and review. It seems like no result is not returning.

During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page.

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
