sql - Total amount of columns in mySQL ! -

-

मेरे पास यह sql है: 

  SELECT *, (xnum * xprice) AS राशि, SUM (xnum * xprice) कुल से xxbasket LEFT JOIN xxsubproduct USING (xsubproduct_id) LEFT JOIN xxcolor USING (xcolor_id) WHERE xuserid = '3'

जब मैं SUM (xnum * xprice) का उपयोग करता हूं कुल मिलाकर यह मुझे केवल एक पंक्ति देता है, लेकिन जब मैं इस SUM (xnum * xprice) को निकाल देता हूं, तो मुझे सभी पंक्तियाँ दी जाती हैं

मेरा सवाल है कि मैं कैसे योग प्राप्त कर सकता हूं? जबकि मुझे क्वेरी से सभी पंक्तियों की आवश्यकता है? योग एक ऐसा कार्य है जहां सभी मूल्यों पर आपके मूल्य (xnum * xprice) का योग की गणना की जाती है।

"post-text" itemprop = "text">

। परिणाम एक पंक्ति है।

यदि आप पंक्तियों के कई समूहों की राशि की गणना करना चाहते हैं, तो आप ग्रुप बाय क्लॉज का उपयोग कर सकते हैं, जो समूहों को समूह में समूह (जैसे GROUP BY userid के बजाय आपके जहां खंड सभी उपयोगकर्ताओं के लिए SUM (xnum * xprice) की गणना करें)

c# - PInvoke of NetUserAdd returns 24 -

-
I am calling NetUserAdd and it is returning 24 for each call. Does anyone know 24 stands for? When I do not know what the error is, it is very difficult to debug it. I'm calling it a Windows XP machine running as a local administrator. I am also a local administrator on the target computer. I tried to do it with USER_INFO_1 and it worked fine. I need a level of control given by USER_INFO_2. This shows the return value for this call. They are further defined by numeric values. Unfortunately none of these values ​​= 24 I know this is a very specific question. I think I'm hoping to find a PInvoke / NetAddUser expert who can help me out there Here in case my code matters.
