 <कोड> सम्मिलित करें dbo.FileColumns (FileID, RowID, ColumnID, मूल्य) का चयन करें FileID, RowID, ColumnID, मूल्य # से TempFileColumns;

मैं मेज dbo.FileColumns पर इस सूचकांक सेटअप: क्लस्टर, अद्वितीय, प्राथमिक कुंजी RowID, ColumnID

पर सूचकांक मैं इस त्रुटि मिलती है: प्राथमिक कुंजी के उल्लंघन बाधा 'PK_FileColumns' ऑब्जेक्ट 'dbo.FileColumns' में डुप्लिकेट कुंजी को सम्मिलित नहीं किया जा सकता।

डालने के दौरान ऐसी डुप्लिकेट पंक्तियां कैसे निकालें? धन्यवाद, धन्यवाद।

आपको यह तय करना होगा कि आप डुप्लिकेट रिकॉर्ड कैसे प्रबंधित करना चाहते हैं। एक तकनीक कुछ व्यापार नियम आपके द्वारा निर्धारित, तारीख या मूल्य आदेश की तरह के अनुसार पहले रिकॉर्ड को चुनने के लिए एक विभाजन के साथ एक ROW_NUMBER उपयोग करने के लिए है। 

  सम्मिलित करें dbo.FileColumns (FileID, RowID, ColumnID, मूल्य) का चयन करें FileID, RowID, ColumnID, मूल्य से (चयन ROW_NUMBER () से अधिक ROWNUM, FileID, RowID, ColumnID, #TempFileColumns से मूल्य के रूप में (द्वारा FileID आदेश द्वारा RowID, ColumnID वाला भाग)) टी कहां ROWNUM = 1

अन्य तकनीकों तुम क्यों डुप्लिकेट फ़ाइल आईडी जब अपने अस्थायी तालिका (शायद कहीं में एक बग) पैदा करने, या समुच्चय का उपयोग कर अद्वितीय fileids (जो इस फिट करने के लिए प्रतीत नहीं होता पाने के लिए मिल को देखने के लिए हो सकता है परिदृश्य)।

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
