I've been browsing and to no avail, I can't find any information on how to select/show only the column header. My objective is to select only column header . I've uploaded a picture for better illustration on my objective. In the picture shown, I'm trying to only select and display the one ive highlighted in the red box.
Oracle table:
The only information I found from the net is selecting an individual column, and with that. It will display the data as well which is not my objective. my main objective is to only select column headings.
In Oracle APEX SQL Workshop you can describe a table with this command:
desc table_name
If you're using a query, you can click on the "Describe" tab below the query and above the result grid.
I had a similar requirement, so in page designer I plugged in a "Where Clause = Sysdate-1"
you can use select and null to pick columns and use alias to name them
select null AS column_name,null AS column_name
from TABLE_NAME

I am using Apex 18.2. I created an interactive report which has 10 records. I try to add a logic that user can only be able to edit those records which recently created. User cannot do an edit to an old records. Means when user try to edit old records, it show as 'Display only' or not editable. Is there any way I can do that? Your help is really appreciated. Thanks
One option is to create your own link (icon, if you wish), just like another column in report's query.
As you're in SQL now, use any condition you want. Obviously, you have to be able to distinguish "old" from "new" rows. If we suppose that it is some DATE datatype column, so whatever is "yesterday" or older is considered to be "old", you'd
select case when datum < trunc(sysdate) then null
else 'Click here'
end as link,
empno,
ename
from emp
LINK column's type would be "link" (of course) and you'd make it navigate to another page in this application, pass values from here to there, etc.
I'm new in Oracle Forms and I would like to display in "Hint" section of my forms a value from every column comments from the table used in the forms. Do you have any idea? Thanks.
You can use get_item_property and set_item_property to dynamically get and set the hint text from items:
Get_Item_Property(it_id,HINT_TEXT);
Set_Item_Property(it_id,HINT_TEXT,'value');
Maybe you want to retrive column table comments in the following way:
select comments
from all_col_comments
where table_name = 'EMPLOYEES'
and column_name = 'FIRST_NAME';
In a form trigger WHEN_NEW_ITEM_INSTANCE at form level,
you could retrive that comment according to the current item and current block.
How to see Table detail when writing query?
Hi, i am new to using Embarcadero DBArtisan for Oracle and Syabase queries executions.
but i am unable to see the tables and fields information when i write queries.
Forexample:
Databasname.User.Table.Fields
Suppose if i write first Database name and write .(dot) it should show me all users and when i pick one user and write .(dot) agian it should show me all tables inside and when i pick one table and write .(dot) it should show me all the fields inside.
But it is not doing that way. every time i have to describe table to find the specific field in the table.
I am woundering if i have to choose some option to see this information.
Thank you very much for your help.
Sybase, there is no User.
I think you have to write a cursor to loop over the DBs on a server.
For the rest of your question:
select db_name() 'databasename', b.name 'table', a.name 'fields'
from syscolumns a, sysobjects b
where a.id = b.id
-- and b.type = 'U' -- User tables only
It seems that there is a setting in Code Workbench. Please see page 733 in the DBArtisan User Guide.
From the Manual,
In the ISQL Window, when Enable Auto Replacement is selected on the Setting Tab,
the application uses "dot completion" auto population to display the list of columns
for the target table.
I am trying to filter the result using sql developer. I got the process to filter the record as right click on column header and select "Columns" option. but In my sql developer there is no option like columns.
The best way to do this, is to use the filter input line, not the column filter.
And then just type: column_name like '%value_to_search%'
Example: NAME like '%john%'
In SQL Developer Version 3.2.20.10, after running a query you can bring up filter on column dialogue box by one of two methods:
Click on the column heading (EMPLOYEE_ID in the screen shot below)
Right click on column heading (Again EMPLOYEE_ID) and select "Filter Column"
I am looking for a way to automatically insert column names in TOAD for Oracle to make it easier for writing queries.
Ideally, I would like to type something like the following:
select * from myTable;
Then, when I right-click on *, I would have the option to insert all known column names for that table.
Is it possible in Toad?
Press F4 on that the selected table name, and in the schema browser, select the Columns tab, then select all columns. Then drag the selection, do not copy&paste, back into the editor, and you have your comma separated column names.
select column_name || ','
from all_tab_columns
where table_name = 'SOME_TABLE'
and owner = 'SOME_OWNER'
order by column_id;
The right click on output of field names in data grid and select Export Data (to clipboard as tab delimited, don't include quoting or column headers).
Now copy/paste where u need it. Nice thing is that you can:
Use this SQL in any IDE, not just Toad
Modify output if needed, as I do in triggers to add ':old' or ':new' prefixes to each field for example, or change order.
It is also possible to generate the statement from the schema browser-> columns tab
Select the columns you want, then right click and select the 'generate statement' menu item,then select the command you want to generate (Select/Insert/Delete).
The script then gets copied to clipboard, for you to paste at your leisure.
