android 点滴积累

代碼錯誤提示: E/AndroidRuntime(1145): Caused by: android.database.sqlite.SQLiteException: near "*": syntax error: , while compiling: SELECT numbertype, new, duration, _id, numberlabel, name, number, type, date FROM calls WHERE (number = **9) ORDER BY date desc  解決:    	strQuery = "number = " + strQueryNumber; 			callLogCursor = TApplication.nowTApplication.getContentResolver() 					.query(CallLog.Calls.CONTENT_URI, null, strQuery, null, 							"date desc"); 							 							查詢代碼改成: 							 								strQuery = "number = " + "'strQueryNumber'"; 			callLogCursor = TApplication.nowTApplication.getContentResolver() 					.query(CallLog.Calls.CONTENT_URI, null, strQuery, null, 							"date desc"); 							 	總結:因為"*"為數據庫里的關鍵字(未經證實),所有查找是會報語法錯誤,只需要拼接字符串,把"*"改成非關鍵字即可
