Providing a more updated Detail

\n\n

Hi All, I have this select query above using UNION ALL. There is a column called Value and VariableID in tmp_datasets table. I need to create 2 separate columns and name them val1 for variableID is 1 and val2 if variableID is 4. If i use UNION ALL it works it creates 2000 records with the first 1000 as val1 records and next 1000 as val2 records but does not separate out into 2 sep columns. How do i separate this value column in 2 separate columns as stated above.

\n\n

I have 2 columns

\n\n
    \n
  • VALUE which has values TEST56,TEST57,230,245
    • \n

  • VARIABLEID = 1 and 4

    • \n

  • TEST56 AND TEST57 comes under variableid == 1

    • \n
  • 230 and 245 comes under variableid == 4
    • \n
\n\n

So based on this above example, I want to create a view where I have 2 columns called val1 if variableid == 1 and val2 if variable id == 4.

\n\n

So it should look something like this

\n\n
    \n
  • val1 = should show test56 and test57
    • \n
  • val2 = should show 230 and 245
    • \n
\n\n

Don't hit me too soon!

\n\n

I know how to add an image in a HTML page... But I want to add the actual image file in this HTML page.

\n\n

There it is, I want my html page standalone, without any folder or file with it. I put the css in the <style> balise for example. Now, I would like to do the same with an image.

\n\n

First question: Is it possible?

\n\n

Second question: Is the imported image file could be added more than once in the HTML?

\n\n

I don't know if I am understandable, so, there is an example of what I want:

I get a deadlock situation in SQL Server 2012.

After running SQL Server Profiler, I got a deadlock graph as below:

\n\n

\"Deadlock

\n\n

When moved mouse over the processes(oval), both processes showed identical PrepareStatement queries (I'm using JDBC).

\n\n

The query I'm using is as follow:

\n\n
MERGE INTO MA4TB_MT_LOG_MSG  USING (VALUES (1)) AS S(Num) ON ( MSG_ID = ? )\n            WHEN MATCHED THEN\n                UPDATE SET \n                    DIST_DATE   = ?,\n                    DIST_CODE   = ?\n            WHEN NOT MATCHED THEN\n                INSERT (\n                    MSG_ID, DIST_DATE, DIST_CODE\n                ) VALUES (\n                    ?,?,?\n                );\n
\n\n

The thing that bothers me is the Index name under the Key lock resource box.

\n\n

I don't have an index called '1' under the MA4TB_MT_LOG_MSG table.

\n\n

MSG_ID is the primary key of MA4TB_MT_LOG_MSG and there are no indexes on DIST_DATE, DIST_CODE.

Any forms of advice on this deadlock situation would be appreciated.

I have a custom listview that has two TextViews and one ImageView in it. It uses a custom ArrayAdapter as it's adapter, and I wanted to add a search function to it. I've looked through every single tutorial I could find, with no luck. However with one tutorial I was able to search through a regular listview (not using a custom adapter), however this will not work for me because I need to show both TextViews and the ImageView. I only need to filter one of the TextViews though, so I don't see how much trouble it could be.

\n\n

Anyway, here is the MainActivity:

\n\n
public class ItemId extends Activity {\n\n    // List view\n    private ListView lv;\n\n    // Listview Adapter\n    ArrayAdapter<String> adapter;\n\n    // Search EditText\n    EditText inputSearch;\n\n\n    // ArrayList for Listview\n    ArrayList<HashMap<String, String>> productList;\n\n    @Override\n    public void onCreate(Bundle savedInstanceState) {\n        super.onCreate(savedInstanceState);\n        setContentView(R.layout.testo);\n\n        Context ctx = getApplication();\n        Resources res = ctx.getResources();\n\n        String[] options = res.getStringArray(R.array.item_names);\n\n        lv = (ListView) findViewById(R.id.list_view);\n        inputSearch = (EditText) findViewById(R.id.inputSearch);\n\n        // Adding items to listview\n        adapter = new ArrayAdapter<String>(this, R.layout.list_item_test, R.id.product_name, options);\n        lv.setAdapter(adapter);\n\n        /**\n         * Enabling Search Filter\n         * */\n        inputSearch.addTextChangedListener(new TextWatcher() {\n\n            @Override\n            public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {\n                // When user changed the Text\n                ItemId.this.adapter.getFilter().filter(cs);   \n            }\n\n            @Override\n            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,\n                    int arg3) {\n                // TODO Auto-generated method stub\n\n            }\n\n            @Override\n            public void afterTextChanged(Editable arg0) {\n                // TODO Auto-generated method stub                          \n            }\n        });\n    }    \n}\n
\n\n

And here is the custom adapter:

\n\n
public class ItemIDAdapter extends ArrayAdapter<String> implements Filterable {\n\n    public LayoutInflater mInflater;\n\n    public String[] mStrings;\n    public String[] mIds;\n    public TypedArray mIcons;   \n    public int mViewResourceId;\n\n    public ItemIDAdapter(Context ctx, int viewResourceId,\n            String[] strings, String[] ids, TypedArray icons) {\n        super(ctx, viewResourceId, strings);\n\n        mInflater = (LayoutInflater)ctx.getSystemService(\n                Context.LAYOUT_INFLATER_SERVICE);\n\n        mStrings = strings;\n        mIds = ids;\n        mIcons = icons;       \n        mViewResourceId = viewResourceId;\n    }\n\n    @Override\n    public int getCount() {\n        return mStrings.length;\n    }\n\n    @Override\n    public String getItem(int position) {\n        return mStrings[position];\n    }\n\n    @Override\n    public long getItemId(int position) {\n        return position;\n    }\n\n\n\n    @Override\n    public View getView(int position, View convertView, ViewGroup parent) {\n        convertView = mInflater.inflate(mViewResourceId, null);\n\n        ImageView iv = (ImageView)convertView.findViewById(R.id.option_icon);\n        iv.setImageDrawable(mIcons.getDrawable(position));\n\n        TextView tv = (TextView)convertView.findViewById(R.id.option_text);\n        tv.setText(mStrings[position]);\n\n        TextView tv1 = (TextView)convertView.findViewById(R.id.itemids);\n        tv1.setText(mIds[position]);\n\n        return convertView;\n    }\n\n\n}\n

matplotlib.use('QTAgg')

\n\n

but as I use this for showing plots no plots are shown. Any suggestions what is wrong and how to fix this. \nI would like to add, that like a month ago before I updated python and python's packages on my workstation computer the matplotlib was working without problems, but now I get this error.

I know this is not a new question and there are already lot of similar questions, but my problem is bit different. I am trying to implement search functionality on ListView. i have a listview as following:

\n\n
ListView list;\nList<HashMap<String, String>> myDataCollection;\n
\n\n

I am reading lot of data from XML and creating from it.

\n\n
BinderMyrData bindingData = new BinderMyData(this,  myDataCollection);    \nlist = (ListView) findViewById(R.id.list);\n// Adding items to listview\ninputSearch = (EditText) findViewById(R.id.inputSearch);\nlist.setAdapter(bindingData);\n/*** Enabling Search Filter * */\ninputSearch.addTextChangedListener(new TextWatcher() {\n        @Override\n        public void onTextChanged(CharSequence cs, int arg1, int arg2,\n                    int arg3) {\n                // When user changed the Text\n                    //Some code to be added no clue..\n                }\n\n                @Override\n                public void beforeTextChanged(CharSequence arg0, int arg1,\n                        int arg2, int arg3) {\n                    // TODO Auto-generated method stub\n\n                }\n\n                @Override\n                public void afterTextChanged(Editable arg0) {\n                    // TODO Auto-generated method stub\n                }\n            });\n
\n\n

I know I have to add some code there in onTextChanged. I have no clue what code... Any help is highly appreciated.
