• [SOLVED] Help, please! Name of column MySQL to FLEX

  Hello!
  I want the name of a column in a MySQL database table for my Flex output application. I searched and found the mysql_field_name PHP function.
  
  The NAME of the TABLE is
  -stations
  
  The FIELDS in table 'stations' are:
  -station_id
  -staiton_name
  
  When I run the application now, I get nothing! Try it yourself!
  Please, I beg you! Help! I am a beginner Flex/PHP, so if you have any ideas for a solution or a different approach to the resolution of this feature, Post it!

• I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I don't understand. You use vo and eo for you to use business components.

  Again, this kind of code call in trouble.

  You must post the changes to make them visible to the eo find vo. You must then run the query for the changes in the business layer strips then you must update the iterator he table is based on.

  In your code I see that happen, hooch maybe because it is more often than not formatted and undocumented.

  My advice is to do a small test case that you can manage with easy sql. Once you get it to run transfer you the results to the actual application.

• Please let me know how I can add a new column with a constraint not null, table already has data, without falling off the table... Please help me on this issue...

  Hello

  I have an emp_job_det with a, b, c columns table. Note that this TABLE ALREADY has DATA OF THESE COLUMNS

  IAM now add a new column "D" with forced not null

  Fistly I alter the table by adding the single column "D", if I do, the entire column would be created with alll of nulls for the column DEFAULT D

  ALTER table emp_job_det Add number D; -do note not null CONSTRAINT is not added

  Second... If I try to add the constraint not null, get an eoor as already conatained null values...

  (GOLD)

  In other words, if I put the query

  ALTER table emp_job_det Add number D NOT NULL; -THROWS ERROR AS TABLE ALREADY CONTAINS DATA

  So my question is how how can I add a new column with a constraint not null, table already has the data, without falling off the table

  Please help me on this issue...

  Add the column without constraint, then fill the column. Once all the rows in the table are given in the new column, and then add the constraint not null.

• Adding 2 columns HELP

  Hello thank you for taking the time to everyone reading this,
  
  I have 1 Table with 3 columns
  
  Column 1 - quantity
  Column 2 - unit cost
  Column 3 - Total amount
  
  I have the user to enter the quantity and unit cost
  
  is it possible to create a mutiplyes function both on a SQL report, which shows me a result.
  
  I tried to use the report attributes > column attributes TOTAL_AMOUNT
  
  HTML expression: #R_QUANTITY # * #UNIT_COST # (Am I close?)
  
  is there another way to gift of this?
  
  Thanks in advance.
  
  Jo3y

  If you talk about a report, then I suppose that the user has already entered data in a form and it has been saved in the database.

  In this case, it would be easier to do this in the SQL statement that retrieves data

  SELECT QUANTITY,  UNIT_COST,  QUANTITY * UNIT_COST AS TOTAL_AMT FROM TABLE_A
  

  The HTML EXPRESSION is not able to do any arithmetic it is purely a HTML string with a variable capacity of substitution.

  Hope that helps,

• How the XML element used in RTF PUBLIC/PRIVATE? I know how to hide columns in RTF, but do not know how to generate xml below way. Help, please.

  Hello

  I'm following link below to show/hide my columns dynamically. See "formatting of column.

  http://docs.Oracle.com/CD/E12844_01/doc/BIP.1013/e12187.PDF

  According to the doc element can be made in private/public.

  <items type="PUBLIC">
   <item>
    <name>Plasma TV</name>
    <quantity>10</quantity>
    <price>4000</price>
   </item>
   <item>
  

  And even can be used to hide the column with the help of State

  <?if@column:/items/@type="PUBLIC"?>
  

  MY QUESTION IS HOW TO DO THIS IN MY XML BELOW?

  Here's the part of my XML code that I use in the definition of the data to RTF.

  <group name="GH3" source="QH3">
  <element name="COLUMN_HEAD3" value="COLUMN_NAME" /> 
  </group>
  <group name="GH4" source="QH4">
  <element name="COLUMN_HEAD4" value="COLUMN_NAME" /> 
  </group>
  

  I'm out like that.

  <LIST_GH3>
  <GH3>
  <COLUMN_HEAD3>REBILL_TO_OTHER_BUSINESS_UNIT</COLUMN_HEAD3>
  </GH3>
  </LIST_GH3>
  <LIST_GH4>
  <GH4>
  <COLUMN_HEAD4>XYZ</COLUMN_HEAD4>
  </GH4>
  </LIST_GH4>
  

  In order to use the logic according to the oracle document I want output like this.

  <LIST_GH3 type="PUBLIC">
  <GH3>
  <COLUMN_HEAD3>REBILL_TO_OTHER_BUSINESS_UNIT</COLUMN_HEAD3>
  </GH3>
  </LIST_GH3>
  <LIST_GH4 type="PRIVATE">
  <GH4>
  <COLUMN_HEAD4>BLANK</COLUMN_HEAD4>
  </GH4>
  </LIST_GH4>
  

  Should what changes I make in my XML to get the result of the execution as above? Help, please. Where should I make changes in the XML above? Name of the Group? Name of the element?

  I intend to use it under condition in RTF model to hide the column, but do not know how to set the column as PRIVATE/PUBLIC type in the XML output that is used to populate the data in the RTF while running.

  <?if@column:/BTSPIEXP/LIST_GH3/@type=”PUBLIC”?>COLUMN_HEAD3<?end if?>

• Plotting bar help please

  Hello

  I have spent some time on it and could really use some help please. I have looked at the plot in real time in the help, searched the forum, but the examples isn't enough similarity for me change.

  The attached vi is a graph of the waveform (with bars) which I use to show a single value read from a text file. The value in the text file will update once every half hour (from a data logger), for a total of 10 hours (20 values)

  I would like to see each point on the graph from left to right with a spacing between the two. The value in the text file will pass (never down) so the plot resulting bars resemble a staircase (but with heights different step). The process will continue with a small break between two periods of update files and previous data points (bars) must therefore be kept (and available by zip, so I can code pretty easily).

  Could someone show me how this could be achieved?

  Thank you in anticipation

  Ray

  Hi Ray,

  Here are a few examples.

  The first - mod bar graph - uses a node back feeding to see if an item has been added to the data file.

  You can consider using a graphic as in the second example - graphic bar. With a graphic, you can change the number of data points to resize the waveform table. In this example, a shift register is used to allow only insert new values into the table.

• Need help with Sql Tunning

  Under Update taking 2 h complete 3000 sets.

  UPDATE ARR_TRANSACTIONS ARR

  SET = NUMBER99

  (SELECT ARR_1.NUMBER99

  OF ARR_TRANSACTIONS ARR_1, ARR_HEADER BH

  WHERE ARR_1.ARR_ID = BH. ARR_ID

  AND BH. FLAG = "Y".

  AND ARR_1.LINE_ID = ARR. ORIG_INV_LINE_ID

  AND ARR_1.NUMBER9 IS NOT NULL

  AND ROWNUM = 1)

  WHERE ARR BATCH_ID = 26219

  AND ARR. NUMBER99 IS NULL

  I added more some condition where to reduce cost and its working fine. But I need to rise more than performance on SQL.

  Please help with SQL.

  I do not see the number of 3000 lines in the plan - so I guess that the optimizer does not compute with the correct numbers. Could generate the plan with dbms_xplan.display_cursor? This could tell us something about filter predicates and access.

  In the given situation, I would check:

  • is the access to the index in step 1 (filtered by the relevant conditions: this could be BATCH_ID = 26219) return actually 248 entries (or something similar)?
  • Access table in step 2 returning 204 lines (or something similar) after applying the filters given? If the number of lines is much bigger then a Nested Loops is perhaps not a good idea.

  To make this much simpler check, you could create a plan with statistics of content (RowSource) given that the plan containing the real and the number of estimated rows.

  If the estimated cardinalities are not plausible the next question would be if the statistics are strong and up to date.

  Oracle doesn't like the ' (select max (bulletin_master_id) + 1 bl_btn_master)' statement incorporated in the CREATE SEQUENCE statement because if you look at the syntax it expects an acual number.» You can use run immediately to create the sequence in this way:

  {code}
  declare
  number of v_seq;
  v_statement varchar2 (200);
  Start
  SELECT max (bulletin_master_id) + 1
  in v_seq
  of bl_btn_master;

  v_statement: = 'CREATE the SEQUENCE BL_BTN_MASTER_SEQ |
  "MINVALUE 1' |
  "MAXVALUE 999999999999999999' |
  ' INCREMENT OF 1' |
  'START WITH ' | v_seq |
  "NOCACHE";

  execute immediate (v_statement);
  end;
  {code}
