sqlite - Insert only if id doesn't exist -

-

ठीक है, इसलिए हमारे पास एक टेबल सेटअप के साथ एक फोनगैप ऐप है

tblTest (actualid INTEGER प्राथमिक कुंजी, आईडी INTEGER, नाम पाठ)

वास्तविक डिवाइस के लिए एक अद्वितीय आईडी है और आईडी एक सर्वर साइड डाटाबेस में बनाए रखा है। हमारे डोमेन में डुप्लिकेट रिकॉर्ड्स लौटने वाले मुद्दों के साथ समस्याएं थीं और जब तक हम तय कर रहे हैं कि मैं अपने एसक्यूएल में कुछ जोड़ना चाहता हूं जो डुप्लिकेट को जोड़ने से रोकेगा (बुरे डेटा को ठीक करना एक दर्द है)।

हमारा वर्तमान

यदि आप डेटाबेस से दो बार चलाते हैं, तो

INSTERT में tblTest (id, name) VALUES (101, 'BOB')

<पूर्व> जैसा दिख रहा है आईडी | नाम 1 | 101 | बॉब 2 | 101 | बॉब

और इसके लिए मैं क्या चाहता हूं 

  actualid | आईडी | नाम 1 | 101 | बॉब   
 सम्मिलित करें या बदलें मुझे एक  actualid 2  उदाहरण में और किसी भी उदाहरण को मैंने पाया है जहां खंड की तरह सेटअप किया गया था  < पी <>> <टी> <टीटी> <टीटी> <<कोड>   
   
 काम नहीं करता क्योंकि कोई डेटा अभी तक तालिका में नहीं है (जब तक कि मैं ' एक नौसिखिया गलती कर रहा हूँ, मैं एसक्लाइट या सामान्य एसक्यूएल पर बहुत अच्छा नहीं हूं)।   
 
 
 उपयोग:  
  INSERT या tblTest (आईडी, नाम) मूल्यों (101, 'बॉब') में IGNORE   
 (यह  पर एक अद्वितीय अनुक्रमणिका की आवश्यकता है आईडी  स्तंभ, जो आपके पास पहले से है।)

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
