Rename of table column messed up field in Edit Screen

I renamed a table column. I have a report page with an edit form page tied to it based on this table. I changed the SQL statement in the Region Source on the report. The appropriate column value is displayed in the report. I changed the Page Item name on the Edit Form page. I changed the Source Value to match the new field name.
The problem I am running into is when I run the Edit Form page and change the value in the item of the renamed column, the field in the database table is blanked out. Even if I change the value to be the same value, the column is blanked out.
What did I miss in renaming the table column?

I've had a similar problem. I added a couple of new columns to a table and attempted to manually add the fields to an existing form. However, as described above, whatever value was entered on the screen, a NULL was stored on the database.
I created a new form using the Form Wizard and copied the columns between pages and got them working. In the process, I tracked the problem down to the variable name.
For example: for the column PRC_SCHEDULABLE, a item named P5_SCHEDULABLE works but any other item name produces the NULL problem.

Please help me I am not seeing Database table column names in field explorer view

Hi,
I am developing a crystal report using eclipse and sql server. After creating connection, when i drag and drop tables, The table name and its columns should apper in field explorer view. Then we drag the columns onto crystal report. Unfortunately I am just seeing only table names but not column names in field explorer view. Could anyone help me?
After downloading eclipse I have plugged in the crystal report using the following instructions
1. Click on the Help menu, and then Software Updates > Find and Install... to open the Install/Update wizard.
2. Select Search for new features to install and click Next.
3. Click the New Remote Site button. This will launch the New Update Site wizard
4. Type the Business Objects Updsate Site for the Name field and the following for the URL: http://www.businessobjects.com/products/dev_zone/eclipse/
5. Click OK to complete the wizard.
6. Enable the newly created Business Objects Update Site checkbox as well as the Callisto Discovery Site (which should appear by default with Eclipse 3.2) and click Finish.
Expand the Business Objects Update Site node and enable the Crystal Reports for Eclipse 1.0.0v555 checkbox.
8. Expand the Callisto Discovery Site and click the button "Select Required". This will automatically select the required Eclipse features necessary to successfully install Crystal Reports for Eclipse.

Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
If you are using SQL Server 2012/2014, then you can use

Rename a table column

Can we rename a column in the database table? If, yes, then how?

In 9i you can rename the column directly:
ALTER TABLE static
RENAME COLUMN oldname TO newname;In previous version it takes more effort:
CREATE TABLE temporary (newname, col2, col3)
AS SELECT oldname, col2, col3 FROM static;
DROP TABLE static;
RENAME temporary TO static; You would also have to care about constraints, indexes etc.
But you could use TOAD, which generate all the necessary statements.

3 columns in table, but just 2 field in edit page = NullpointerException

Hi!
I have a h:dataTable with 3 columns (modul_id, modul_name, synonym_name), but i want to edit just 2 fields in the edit page: modul_name, synonym_name.
I must call an UPDATE sql statement, when the user click to submit and I need the value of modul_id as well.
UPDATE nxt_moduls SET modul_name=?,synonym_name=? WHERE modul_id=?But when I want to set the value of modul_id for PreparedStatement, I get a NullpointerException, the modul_id is null.
There are just two inputText on the edit.jsp one for modul_name and one for synonym_name. I think, that I must return the value of modul_id somwhow as well. When I put a third inputText for modul_id, then it worked, but I don't want to allow to edit this.
This is my edit.jsp:
<html>
     <body>
          <f:view>
               <h:form>
                    <h:panelGrid columns="2">
                         <h:outputText value="Module name"/>
                         <h:inputText id="modul_name" value="#{nxtModulsBean.itemNxtModuls.modul_name}"/>
                         <h:outputText value="Synonym name"/>
                         <h:inputText id="synonym_name" value="#{nxtModulsBean.itemNxtModuls.synonym_name}"/>
                    </h:panelGrid>
                    <h:commandButton action="#{nxtModulsBean.saveItemNxtModuls}" value="Save"/>
               </h:form>
          </f:view>
     </body>
</html>and this is the java code for save operation:
     void updateNxtModulsInDB() throws SQLException, NamingException {
          String sql = new String("UPDATE nxt_moduls SET modul_name=?,synonym_name=? WHERE modul_id=?");
          java.sql.PreparedStatement PreStat = ownGetConnection().prepareStatement(sql);
          PreStat.setString(1,itemNxtModuls.getModul_name());
          PreStat.setString(2,itemNxtModuls.getSynonym_name());
          PreStat.setLong(3,itemNxtModuls.getModul_id());
          PreStat.execute();
          PreStat.close();
          ownGetConnection().commit();
     }here stops: PreStat.setLong(3,itemNxtModuls.getModul_id());
Please help me!

Currency Key Reference field in WebDynpro Table Column

Hi Experts,
I am using a WebDynpro table (not ALV) showing multiple currency fields in a single row - each one potentially referencing a different currency key e.g. Japanese Yen and USD in a single row.
My currency context attributes are already defined as currency types, but how can I assign different currency key references to each of my currency context attributes? Or is this somehow done as a property of the table column UI element?
Thanks for your help,
Peter

Hi Kris,
You answer is very helpful, but I do have a question about going the DDIC route. So you are saying that if I take a DDIC structure into my context with multiple currency keys as reference fields for multiple currency fields, then my WebDynpro context will know exactly which currency key is the reference for which currency field without having do do this programatically as you described? If that's true, can I bring a whole DDIC structure over to the context and then delete the 'Dictionary Structure' refrence from my context node, so that I can add my own additional fields to the context node? E.g. in the case of DDIC structure VBAP can I get all my currency fields and their reference fields from the DDIC from VBAP and then delete 'VBAP' as a 'Dictionary Structure' from my context node and add my own custom fields. The fields I would have brought in from VBAP still retain their type and everything after the deletion of 'VBAP' as a 'Dictionary Structure', so my question is will it also retain the node_info of what currency key goes with what field?
Please let me know if you happend to have done this before.
Thanks,
Peter

How do you count the multiple columns of a field in a table

How do you count the multiple columns of a field in a table

Hi,
4396bf34-e890-4202-a6b0-4e08c9ff0e89 wrote:
How do you count the multiple columns of a field in a table
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002
"Field" isn't a standard database term. Some people say "field" when they mean "column", but I don't think that's what you mean ("How do you count the multiple columns of a column .."). Do you want to know how many times a column is used (as opposed to NULL), or the number of different values in a column? You really need to show what you want.

Add columns with custom fields in the table control of MIGO

Hi,
I have to add custom fields in the table control view of item in the MIGO. I have added the fields in the GOITEM structure and i am able to display it in the item details tab. I want the same fields to be visible as columns in the table control view of the items.
I found that TV_GOITEM is the control in SAPLMIGO program referring to the table control of items but it is referring only to the standard fields available in Screen 200.
Please let me know if there is any screen exit or option to add the custom fields in the control TV_GOITEM.
Thanks.

Hi,
Thanks for your reply. I have added the custom fields in the item detail. But the customer wants the custom fields in the table view also.
Is there any screen exit available to modify the table control of MIGO?
Thanks.

Rename a table

I am using Crystal XI. The database table has been renamed and I need to rename the table in several reports. I used to be able to use SetLocation and point the new one to the old one and press update... but that does not appear to work.
What is the easiest way handle renaming a table? If I drop and re-add it, it messes up all my groups and fields that I have placed in the report
Thanks,
Jeff

Hello Jeff,
I recommend to post this query to the [Crystal Reports Design|SAP Crystal Reports; forum.
This forum is dedicated to topics related to the creation and design of Crystal Report documents. This includes topics such as database connectivity, parameters and parameter prompting, report formulas, record selection formulas, charting, sorting, grouping, totaling, printing, and exporting but also installation and registering.
It is monitored by qualified technicians and you will get a faster response there.
Also, all Crystal Reports Design queries remain in one place and thus can be easily searched in one place.
Best regards,

Multi-record / spread table...moveable fields in designer generated form

Good morning all;
I hope you are doing good...
Imagine a multi-record block layout with it's overflow property set to spread-table to accomodate 10 varchar2(25) fields. Now, of the hundreds of users working with this generated form, not one of them wants to see the fields in the same order on the screen.
What i would like to do is generate the form from designer so that a user could 'drag'n drop' let say, field #10 to the field #2 spot on the screen. Something like windows explorer where you can move the 'Size' column around so it is viewable without having to use the spread-table bar at the bottom of the screen...
Any idea on how to generate this form from designer?
Thank you and wish me luck!

I don't know a solution, but I think a solution could be easier found if it was a read-only block. You did not specify that. Then maybe you could dynamically change the query behind the block.
Good luck, Paul.

Which option to use to search text in multiple table columns

Hi, I have a case where I have 4 db tables. On the UI there is an option to search a keyword from some columns of these 4 tables.
Table1 = summary, description are the columns user can search on
Table2 = project_name is the column user can search on
Table3 = need_by_date is the column user can search on
Table4 = owner is the column user can search on
On the UI, user can enter a keyword and check the columns they want to search on. Out of the above, they can check one column, or more, or all.
My question is what is the best option to use oracle text search in this case.
Option 1 = I create a procedure to select these columns and then create an index on this procedure. In this case, is there a way to specify
which columns to search on?
Option 2= Create 4 separate indexes on these table/columns and then query the columns which user has selected to search on.
Any other better idea?

Hi,
multicolumn only works on columns in the same table.
If you can also query just on one field, then an index per field will be preferable. If you query always on all the fields then the one index approach is good. For this last the options are:
1. Use User_datastore, create a procedure and a dummy column
2. Create a materialized view for the query and build an index on this materialized view
3. Store the fields as an xml in the main table and index the xml column.
The maintanance of options 1 and 3 are bigger, because you need triggers to be aware of an update. Option 2 and 3 will need more storage.

Table Column - Different UI elements in a column

Hi,
I have the following requirement. I need to create a table shown below.
            COLUMN1              COLUMN2
ROW1      cell11                    cell21
ROW2      cell12                    cell22
I need cell11 and cell22 to be textviews and cell12 and cell21 to be inputfields. In other words, I need different cells in a table column to be of different types.
How do I do this.
Thank

Hi,
An easier way to switch between input field and text view is to just bind the readOnly property. Why actually switch between InputField and TextView.
Create an attribute 'EDITABLE' type Boolean in the node that is bound to the table.
1.Create all the cell editors as input field.
2.Bind the readOnly poperty with the attribuite 'EDITABLE'
3.Now pass abap_true to make it a text view and abap_false to make in input enabled.
However it is possible to switch between different UI elements using Cell Variant .

I need the "Real" Table / Table Column names from a sql view

Firstly, we have a system with ~1000 tables and ~250 views. We have field level security on the table columns (in our code)
Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
I know there are view columns that is not linked to a specific table column, (or concatenation of columns) so those columns can just return NULL.
From the sample you will see there is a view selecting data from another view. I know it is not the best sql performance (execution path) but that is another topic on its own.
I went through a lot of the sys.* stored procs or sys.* views to try and figure out if there is a view that we can use to get the expected results.
here is the sql code:
if

sys.all_objects

drop view dbo.AliasView2
if

drop view dbo.AliasView1

BEGIN
