sql - ignore insert of rows that violate duplicate key index -


मैं एक सम्मिलन निम्न प्रकार से करता हूं: 

  INEERT IN foo (a, b, c ) एफयूआर से एक्स, वाई, जेड का चयन करें ...

हालांकि, अगर कुछ पंक्तियां जो डाली जा रही हैं, foo पर डुप्लिकेट कुंजी इंडेक्स का उल्लंघन करती हैं, तो मैं चाहता हूं कि डाटाबेस उन पर ध्यान न दें पंक्तियाँ, और उन्हें सम्मिलित न करें और अन्य पंक्तियों को सम्मिलित करना जारी रखें।

प्रश्न में डीबी Informix 11.5 है। वर्तमान में ऐसा ही होता है कि डीबी एक अपवाद फेंक रहा है। अगर मैं इसके साथ अपवाद को संभालने की कोशिश करता हूं:

<पूर्व> में अपवाद पर (-239) एंड रेड्यूम के साथ अंत में अपवाद;

... यह मदद नहीं करता क्योंकि अपवाद के बाद पकड़ा गया है, पूरे सम्मिलित किया गया है।

मुझे नहीं लगता कि informix INSERT IGNORE का समर्थन करता है, या INSERT ... डुप्लिकेट कुंजी पर ..., लेकिन अगर मुझे गलती है तो मुझे सही करने में संकोच न करें।

IF स्टेटमेंट का उपयोग करें और मौजूदा रिकॉर्डों की जांच करने के लिए EXISTS फ़ंक्शन का उपयोग करें। या आप संभवत: नीचे दिए गए दाएं खण्ड में उस EXISTS फ़ंक्शन को शामिल कर सकते हैं 

  INFER IN FE (a, b, c) SELECT x, y, z fubar कहां से (वर्तमान में नहीं (एक से चुनें Foo WHERE ...))

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
