How to display data from the emp table?

• How to compare data from the two table column by column and connect the result compared to the separate table

  Hello experts...

  I'm new to this forum and Oracle coding complex.

  I have a task in which I want to compare two tables with the same structure, same columns. My Oracle database is 11g Release 2. I want this column-by-column comparison and save the result in a separate table. (say result_table)

  The structure of the table would be as follows:

  SQL > desc emp;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  SQL > emp_comp desc;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  Both of the tables EMPNO is the primary key.

  I want to compare these two tables based on the EMPNO (EMPNO even is both tables).

  The result log table would be as follows:

  SQL > create table result_table

  2 (check_sr_no, number (5),)

  table_name 3 varchar2 (30),

  ROW_ID 4 varchar2 (20).

  column_name 5 varchar2 (20).

  6 column_data varchar2 (1000).

  compared_by 7 varchar2 (10));

  Table created.

  SQL > alter table result_table

  2 Add the constraint result_table_pk

  3 primary key (check_sr_no);

  Modified table.

  The name of the table and the name of the column will not be hardcoded (based parameter by user)

  I tried to use the dbms_comparison package, but do not find comparison of column to column.

  I also used by using the query operator LESS. It's showing the difference in rank.

  I also went to https://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:2151582681236

  Your help will be very appreciated.

• Display data from the database in a table

  Hello
  
  How to display data from my database in an ADF table using a backing bean? I created an arraylist in the bean, but only the last row of my query is displayed in the table...
  
  Thank you...

  Hello

  Create a simple Java class that implements Serializable. Create attributes that represent each column in your table. This class represents on the row of your table. A list of these objects, and you can fill your af:table.

  Hello

  As I said on your other thread:

  In order to write in the shared directory/documents, your application should request action "access_shared" and it must be granted by the user. Make sure you have

  access_shared

  in your bar - descriptor.xml.

  Also note that the shared documents folder may not be the best place to write the application log data. There is one connects / in the sandbox to this effect, or the application directory data / directory if the information should be persisted. The documents/shared/folder is designed for documents that the user creates or interacts with.

• How to write data from the acquisition of data in NetCDF format?

  I connect to a set of data from the sensor through the DAQ assistant and want to write all data in NetCDF format. I have the required plugins installed, but still can not find how to do this.

  Or the labview can only read the netcdf files, but cannot write it! Please let me know if there is any other way out. I have looked everywhere but could not find something useful!

  Sorry, the sheet in effect only allows to read NetCDF files, not writing to the NetCDF format.

• How to send data from the client to the server using tcp

  1. as I am new to watch I need help with sending data from client to server. I went through various examples of labview, but each of them also explains transfer of data to the client server. But I need help regardng send data from the server to the client.

  2.i would use the data type variant for sending my data.

  Can someone help me please. Thank you

  Regardless of the meaning. Once you have a connection each end allows it to send data to another. Just create what you want to look like interaction.

  Do you want the client sends a command that request data?
  How do you think the response data to look like?

  You can send variants, but probably not worth the effort.
