database - Oracle - Compare rows with large number of columns -

-

I have to compare 2 rows with a large number of columns.

This is something like this: ID A column 1 column 2 ... ID B column 1 column 2 ..... ID C column 1 column 2 ..... < / Pre>

I want to compare columns in large quantities like subtract them from them. I do not want a zero from the tables, I want to take similar action on all the columns. Any call should tell me how to name each column without referencing 

  CDE01 A 06 CD PDE02 B 07 CD PDE 03 A 05 CD   < / P>  
 So if I compare with CDEAD then 2 and 3 columns in the other rows are identical. I have several columns that require matching. There are two types of rows in the table and I have to compare each row of a set, where there will be a section with the second row of the second row. There are two different types of lines, like PDE and CDE.  
  
 
 
 why you do not make two views or need more). Each scene shows what you consider as cloaking (you call them like rows). So you can end up with a sequence: CDE_Data and PDE_Data  
 Then you have to decide what it means for the rows to separate. I do not get any match from the data provided by you - You need to determine how a line from CDDAD will match a PDE_Data line, so that you can use that second column (A and B) To match. If this is the case, then join the cde_dta on pde_data based on it and then use the solution here:

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.

jsp - Google line chart x-axis shrinks on transition -

I am using a Google line chart on my page, which refreshes every 5 seconds but weird thing It is that every refresh chart causes the line to be removed, although the size of the chart remains the same. My script - google.load ('visualization', '1', {package: ['corechart']}); Google.setOnLoadCallback (drawLine); // call clickChart when the google.load () function meets the drawLine () {var gaugeData = new google.visualization.DataTable (); GaugeData.addColumn ('string', 'time'); // X-axis gazeta.dk column ('number', 'memory'); // Y-axis gazedata.edc column ('number', 'cpu'); // Y-axis square gauge option = {title: 'system description'}; // tile of var gauge chart; Var tempArray; // store json object value from server var tempArray2; // Server gauge = Modify the json object value = new google.visualization.LineChart (document.getElementById ('line_chart_div')); SetInterval (function () {$ aja...

java - Reaching JTextField in a DocumentListener -

So, I ended up making a Sudoku Solver, but I want to improve it. To do this, I need to reach betterJTextField to documentListener . I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) . I need to reach Better Zest Field that happened to DocumentEvent . For example, if invalid input, would be better zestfield turn red etc. I have all my better zestfield in the matrix if you should know. Each area handles a number in the Sudoku. @ Override public zero inserted (DocumentEvent e) {// Code removed which checks that the input in the fine zest field is OK. } ( JFormattedTextfield extended JTextField ) public class betterJeststeffiledJFormattedTextField {private int row; Private int column; Public BetterJustStस्टfield (format format, infinite row, EIT column) {super (format); This.row = Line; This.column = Column; // To-O Auto-Generated Constructor Stub} Public Ent Miller () {ret...
