Using toad to search for columns in entire datamart

can anyone inform me if it is possible, using toad, to conduct a "quick search" search though an entire datamart for a specific column name and if possible how?
eg: column <pubs_visited incambridge> exists in table <things_to_do_in_cambridge> in a datamart and i want to find out if the column <pubs_visited_in_cambridge> is repeated in another table within the datamart.

<QUOTE> Not really true, all_tab_columns will give you all tables for which you've grant.</QUOTE>
tried executing the query with both (DBA_TAB_COLUMNS AND ALL_TAB_COLUMNS) and I have received different results (more results with the dba). apparently, the schema i queried in our datamart, does not contain some of the tables that have been listed using the dba function.
how could it be possible that tables which do not exist in a specified schema get listed when quering using the dba function?

How can I use SQL to search for a pattern within a field?

Hello, Frank, Solomon, ect
I am now faced with this particular scenario, I've got the SQL to search through a field to find text within the field, but I have to know what it is before it can look for it.
What I have to do is this:
Search through a field, for a pattern, and I won't know what the data is I am looking for. Can this be done in SQL?
For instance, Here is my SQL this far, I was helped allot in order to get to this point.
select table_name,
 column_name,
 :search_string search_string,
 result
from (select column_name,
 table_name,
 'ora:view("' || table_name || '")/ROW/' || column_name || '[ora:contains(text(),"%' || :search_string || '%") > 0]' str
 from cols
 where table_name in ('TABLE1', 'TABLE2')),
 xmltable (str columns result varchar2(10) path '.')
When you execute the above SQL, you have to pass in a value. What I really need is to alter the above SQL, to make it search for a pattern that exist's within the text of the field itself.
Like for instance, lets say the pattern I am looking for is this" xx-xxxxx-xxxx" and it's somewhere in a field.
I need to alter this SQL to take this pattern and search through all the schemas and tables to look for this pattern match.
Can be done?

When you use something dynamically within a function or procedure, roles do not apply and privileges must be granted directly. So, you need to grant select on dba_tab_cols directly. If you want to do pattern matching then you should use regular expressions. The following example grants the proper privileges and uses regexp_instr to find all values containing the pattern xxx-xxxx-xxxx, where /S is used for any non-space character. I limited the tables in order to save time and output for the test, but you can eliminate that where clause.

SYS@orcl> ALTER USER test QUOTA UNLIMITED ON USERS

Search for column in all tables

I want to search for a column value(example instance_id=123456) in all the tables using one query rather than describing each table to find first if instance id exist and if so do a select from that table.

You could try some sort of variation of this:
DECLARE
   value_of_interest    NUMBER := 12345;
   vTable          ALL_TAB_COLS.TABLE_NAME%TYPE;
   vExist          ALL_TAB_COLS.COLUMN_NAME%TYPE;
BEGIN
   DBMS_OUTPUT.PUT_LINE(RPAD('TABLE',45,' ') || ' ' || 'EXISTS');
   FOR rec in (SELECT TABLE_NAME FROM ALL_TAB_COLS WHERE COLUMN_NAME='INSTANCE_ID')
           LOOP
                   EXECUTE IMMEDIATE 'SELECT ''' || rec.table_name || ''' AS TAB,DECODE(count(*),0,''NO'',''YES'') AS EXIST FROM '
                           || rec.table_name
                           || ' WHERE INSTANCE_ID=:value '
                           || 'GROUP BY ''' || rec.table_name || '''' INTO vTable,vExist USING value_of_interest;
                   DBMS_OUTPUT.PUT_LINE(RPAD(vTable,45,' ') || ' ' || vExist);
           END LOOP;
EXCEPTION
   WHEN NO_DATA_FOUND THEN
           DBMS_OUTPUT.PUT_LINE('No Results found!');
END;Please be aware this that has not been tested, and may have to be modified for your use.

Search for column name in DB tables

Hi Guys
Is it possible to search column name when we do not know the corresponding table in the databse
Cheers
shabar

You can use the data dictionary to search though a list of all column names. The <strike>table</strike> data dictionary view is ALL_TAB_COLUMNS.
Lets assume you want to search for ID columns:
example
select owner, table_name, column_name
from all_tab_columns
where column_name = 'ID';Edited by: Sven W. on Jun 21, 2011 1:47 PM

How to use resource bundle entries for column names/title in .rpt file

Our application needs to be able to support reporting in multiple languages. Hence we do not want to put language specifiec column names in the rpt file but rather use text for a particular locale during runtime which in java world is easily achievable using Resource Bundle entries.Does JRC allow for using resource bundle entries as column names or for that matter for titles etc. in the .rpt file?

Hi,
You can follow this step-by-step tutorial to find out how to achieve this using our User Function Libraries (UFLs). The walkthrough can be found here:

Messages icon not appearing on iPad 1, although able to use when I search for the application

I have an iPad 2 that has messages installed after updating to ios5. My step daughters iPad 1 has the messages built in app but it does not appear on any home screen. If we search for the application it shows up and we are able to use it.
Is there anyway he can get the app icon to appear on the home screen?

If you press Ctrl and F5 at the same time, does that change? I believe Google (I'm assuming that is what you are referring to) changes search results somewhat based on if you are signed in and your preferences, etc. Try signing out of google if you are signed in.

Use variable in SQL for column name

Hi All,
We want to use a user input as a column name in APEX.
For e.g user will enter "ALLOWABLE_AMOUNT" then the query will be as follows :
select Rule,rule_name,rule_desc,"User Input" from rule_dim
where "User_input" > 100
So here the User_input will be substitued with Allowable_amount. Is this doable using any bind/substitution variables ? I tried ":P2_USER_VARIABLE" and "&P2_USER_VARIABLE." but did not work.
Please advice.

Hi Andy,
You do that with an Interactive Report and a Dynamic Action.
I'll assume that you're using APEX 4.2
Here's how:
Create Page 2 with an Interactive Report
Create New Page > Report > Interactive Report > Next > Next
Enter a SQL Select statement: select Rule,rule_name,rule_desc from rule_dim
Next > Create > Edit Page
Create the item P2_USER_VARIABLE
Add Item > Number Field > Next
Item Name: P2_USER_VARIABLE
Next > Next > Next
Source Used: Always, replacing any existing value in session state
Source Type: Static Assignment (value equals source attribute)
Create Item
Create a Dynamic Action to refresh the Interactive Report when P2_USER_VARIABLE is changed
Add Dynamic Action
Name: Refresh IRR
Next >
Event: Lose Focus
Selection Type: Item(s)
Item(s): P2_USER_VARIABLE
Next >
Action: Refresh
Next >
Selection Type: Region
Region: Report 1 (10)
Create Dynamic Action
Add the ALLOWABLE_AMOUNT to the Interactive Report
Report 1
Region Source: SELECT * FROM (select Rule,rule_name,rule_desc, :P2_USER_VARIABLE AS ALLOWABLE_AMOUNT from rule_dim) WHERE ALLOWABLE_AMOUNT > 100
Apply Changes > Apply Changes
Get the Interactive Report to submit P2_USER_VARIABLE
Report 1
Page Items to Submit: P2_USER_VARIABLE
Apply Changes
Change the Heading for ALLOWABLE_AMOUNT in the Interactive Report
Interactive Report
Change the Heading of ALLOWABLE_AMOUNT to &P2_USER_VARIABLE.
Apply Changes
Run
Enter something into the USER VARIABLE field and select something else on the page. Watch the last column update to that value.

How to use the spotlight search for photos imported onto an apple ipod model MB528BT

I have an apple ipod model MB528BT version 4.2.1 (8C148) Im think its an iPod touch as opposed to the old iPod but cannot be certain. So first of all does this model number mean anything and/or can I confirm myself via the unit itself?
Assuming its an iPod Touch my question is :-
I have copied photos from a dvd I purchased for identifying birds onto my iMac which I readily search via spotlight.
Having downloaded these photos onto my ipod when I conduct a spotlight search it only finds the birdsong but not the image! Cannot get into settings for spotlight to set for images. If of course this is the answer.
Anyone know the answer please!
Thanks David

You can sync as many ipods/ipads/iphones as you like to one computer.

I want to delete some of the websides who where open on times and i used Google to search for it , but know i will delete it

Remove web pages from google search

As an ex-MobileMe user (I assume) your account storage has been increased for free until the end of September next year. At that time if you do nothing your account will revert to 5GB and there will be no charge. If you don't at that time wish to pay to continue to use the extended storage you should ensure that your account usage doews not exceed 5GB - if you exceed it at that time you won't be charged but you may lose some data. You won't at any point be charged without your specific agreement.

How can I change the default country Google uses when I search for things on the search bar on the Google Chrome app for the iPad 2?

Whenever I search using the search bar, the Google Chrome app always uses google.com.ph as I bought and set up the iPad in the Philippines. How can I change this to google.com or google.ca permanently?

Using JavaScript to search for dates in PDF

Hello,
I have a question about using JavaScript in Adobe Acrobat X Pro.
I want a script that automatically search dates which fall within one week of the date of today.
If this is true then the pdf file have to be deleted. If the date is later then one week of the date of today then the pdf file must be moved to a different folder.
I hope anyone can help me with a solution.
With regards,
Robert

Searching is the easy part. The problem is that a script can't delete a
file, nor can it move a file to another problem.

Query Builder: Search for column

The feature to dynamically expand/shrink the table list as I type stuff in the search box is great.
But some of my tables have over 100 columns, I want to display all the tables/views having "ACCNT" in the columnname.
How can I do that?
Thanks

Hello,
In the Query Builder you can't but that sounds like a very good enhancment. Please idrop it in the 2.0 bug/wishlist app and we'll see if we can get it into a future version.

Using pacman to search for packages - libraries no more used / needed

Is there a way to use pacmant to "clean out" the system, by searcing and deleting all packages and libraries no more needed nor used by anything?

Are you looking for options different from these? http://bbs.archlinux.org/viewtopic.php?id=88987
I don't think there's a completely automatic way. At least, not a way that I would trust.
