c# - Use OleDbDataAdapter to insert into an Access db -

-

मैं कुछ डाटा को एक्सेस डाटाबेस में डालना चाहूंगा। 

  DataTable dt = new विवरण सारणी(); स्ट्रिंग sql = string.Format ("SELECT * FROM {0} जहां 1 = 0;", tmap.SqlTableName); स्ट्रिंग con = string.Format (conn, accesspath); OleDbDataAdapter da = नया OleDbDataAdapter (sql, con); OleDbCommandBuilder cmdBuilder = नया OleDbCommandBuilder (da); Da.InsertCommand = cmdbuilder.GetInsertCommand (सच); // रिटर्न "INSERT परीक्षा (int, bdate, amt, text, bit) VALUES (?,?,?,?,?)" Da.Fill (dt); // DateTable के लिए डेटा जोड़ें (int i = 0; i & lt; rowCount; i ++) {DataRow dr = dt.NewRow (); // .... dt.Rows.Add (dr); } Da.Update (dt); // यह वह जगह है जहां चीजें दक्षिण चलती है

System.Data.OleDb.OleDbException
संदेश: निषेध बयान में सिंटैक्स त्रुटि। स्रोत: माइक्रोसॉफ्ट जेट डाटाबेस इंजिन।

अगर मैं बदल जाता हूं Insert command: 

  da.InsertCommand = new OleDbCommand ("INSERT परीक्षण ([पाठ]) मूल्यों (?)");

और इनकमिंग डेटा को केवल एक टेक्स्ट वैल्यू में बदलने के लिए जो मुझे मिलता है:

एक या अधिक आवश्यक पैरामीटरों के लिए कोई मान नहीं दिया गया है।

क्या मैं कुछ भूल रहा हूं?

समस्या डेटा प्रकारों में थी प्रश्न का कोड काम करता है यदि डेटा प्रकार संगत हैं।

Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
