Column Searching

Dear Team
I required query to find the table name and schema name
My Question is
I have 5 schema and i know only the column name
i want to find the table and schema name.
Is there any query..?
Thank Advance..

You can query the data dictionary:
SELECT t.owner, t.table_name, t.column_name, t.data_type
FROM dba_tab_columns t
WHERE t.column_name = 'MY_COLUMN';If you don't have access to the DBA_TAB_COLUMNS view you may want to try it using ALL_TAB_COLUMNS or USER_TAB_COLUMNS logged as each of your 5 schemas to check them individually, just to make sure you have the privileges on the desired table.

Interactive report column search not working

Hi,
On Apex 4.01 and discovered that when using the individual column search functionality (clicking on the column label), the search on a column for a userid, the dropdown listing is not showing all userids that are clearly listed in the report. For example, the dropdown only shows up through IDs starting with 's--------' so when I search for an ID with 'vm' it does not show it, yet I can do a sort and go down the rows on the report and find it. Is there a limit to the dropdown list? Or is this a bug?

Multiple Column search based on column name

Hi, Can anybody please help me with my issue. I have a table containing about 100 columns, I am using application express. I want to use a textbox for input, and input will be column name i.e. say one of the column name is "PARK" when user type park in that textbox and click on go or search it will display the records for "PARK" column. How can I do that.
I am trying like this - select :P124_PARK_NAME from wp_parks.
it displays the result but display "PARK" instead of actual data for that column. Please help...

I would prefer some thing like this.

Reg: Nullable column search

Hi all,
I have a table DIAGNOSIS which has a QDESC as a nullable column.
columns DIAGCODE and SDESC are not nullable.
I have written a Stored Procedure to retrieve records from DIAGNOSIS table based on the columns values specified.
p_<column_name> indicates the parameter passed to the Stored Procedure
The correspong SQL statement goes as follows.
SELECT * FROM DIAGNOSIS
WHERE
UPPER(DIAGCODE) LIKE
(CASE WHEN LENGTH(p_DIAGCODE) > 0 THEN '%' || UPPER(p_DIAGCODE) || '%' ELSE '%' END)
AND UPPER(SDESC) LIKE
(CASE WHEN LENGTH(p_SDESC) > 0 THEN '%' || UPPER(p_SDESC) || '%' ELSE '%' END)
-- QDESC is a nullable field; but the following logic doesnt work :-(
AND UPPER(QDESC) LIKE
(CASE WHEN LENGTH(p_QDESC) > 0 THEN '%' || UPPER(p_QDESC) || '%' ELSE '%' END)
Sample data of the table is as follows.
DIAGCODE SDESC QDESC
123 DESC 1 AAA
123 DESC 2
123 DESC 3 BBB
123 DESC 4
When I use the above query to find records with DIAGCODE as 123, I get
DIAGCODE SDESC QDESC
123 DESC 1 AAA
123 DESC 3 BBB
i.e QDESC with null values are not displayed.
How am I supposed to modify the query to get the correct result?
Any help would be highly appreciated.
Thanks n Regards,
Tanuja

Let's assume the formal parameter is called p_column_name.
The actual content of that parameter is 'DIAGCODE' or 'Q_DESC' or whatever.
In static sql
you can only have
<column_name> = <constant>
and <constant> can be replaced by a bind variable.
This construct
select *
from <table>
where p_column_name is null
is not going to work, as there is no p_column_name in that table.
This construct
declare
dynstr varchar2(100);
p_dummy varchar2(100);
p_column_name varchar2(30);
begin
p_column_name := 'bar';
dynstr := 'select bar from foo where '||p_column_name||' is null';
execute immediate dynstr into p_dummy;
end;
although silly dummy code is going to work.

Comma Separated columns - Search

Hi fellow,
I need to query my db with a comma separated list but the results are not correct...What is the reason?
My typical db problem_code column has valuas as :
Problem_code
1
2,3
5,6,7,8
5
And the list values I am sending as ("1","3")...etc
SELECT * from table
whereproblem_code in ('2','1')problem_code in ('2','1')
Thank you in advance..

If you're sking SQL questions, you'd better off asking on a SQL forum. But here you are, so let's have a look at it.
Firstly, the other thing to always mention when raising an SQL question is to articulate what DB system you're using. Because all of them handle SQL differently, and have their own extensions.
In fact reading this is probably a good idea: http://www.catb.org/~esr/faqs/smart-questions.html
Problem_code
1
2,3
5,6,7,8
5
And the list values I am sending as ("1","3")...etc
SELECT * from table
whereproblem_code in ('2','1')problem_code in ('2','1')
Thank you in advance..
What are you seeing here that's not expected (I presume the double-up of problem_code in ('2','1') is a typo)?
Are you wanting to get any rows from TABLE which have either 1 or 2 in them? That's not what you're asking for in your WHERE statement though, is it?
Really, you should be normalising your data, because whilst you can write contorted logic to do what you need here, it will not perform well and certainly will not scale. So it for be somewhat poor practice to perpetuate the current situation if it's at all possible not to. The best thing to do is to normalise your data and refactor your code. Which will probably mean going to your boss and say "this DB schema is f*cked, and needs reworking. Needs reworking".
Depending on your DB system, you're probably going to need to loop over the list you want to filter on and do a "WHERE problem_code LIKE" on each element of the list. I think Oracle can do the sort of query you want to do - match elements of one list from another list - but I'm not sure.

Ranking search function based on column content

We need to search on many docs saved in database. These LOBs has one column KEYWORD VARCHAR2 (64), in which we should put some words that help user who want to search on these values.
Is there any explanation (code) how to rank found docs by this KEYWORD field. Something like google but much poorer and based only on one column search.
THX!
P.S:
My config is Oracle XE

You can use the score function.

Ability to query on all columns from a view with multiple tables

I have view with 4 tables. view has about 50 columns.
hypothetically, I want to build a form to give the user an ability to query on any of those 50 columns. user can search on one or more fields.
what is the best way to write the query to retrieve the results without performance impact.
please let me know if the question is not clear.

If you want to permit them to query any of 10 fields with no restrictions, you could create 10 separate single-column indexes. The optimizer would have to try to pick the best of these indexes if you specified multiple search criteria. But since you have a view which presumably means that you've got multiple other indexes involved for the underlying join conditions, you'd probably want/need to combine the column lists of the indexes you're adding for searches with the indexes you've created for joins, which requires looking at the text of the view and figuring out the best way to optimize the 10 single-column searches. Of course, it is possible that the optimizer could chose to do something like a b-tree to bitmap conversion on multiple indexes which could allow it to use multiple independent indexes for your queries, but that's generally not ideal performance-wise.
All this is a fancy way of saying that there probably isn't a cut and dried answer to your question. You need to figure out the queries you're trying to optimize (say, the 10 single-condition queries) and you need to figure out what set of indexes on the various underlying tables provides the best performance weighing those benefits against the cost on other side of maintenance during DML. Which is going to depend on the text of the view, the underlying tables, the existing indexes, etc.

Apex 3.1, Interactive Report Row Text Search, image bitmap as TEXT?

I think this IR thing is powerful which could save me lots of time in development.
One question: does the row text search(default: all columns) treat image column as regular text(string)? I did the following search on:
SAMPLE APPLICATION-->Products, I put 300 in the search column( for $300 list-price search), the search produces 3 lines( should only have 2). the 3rd line's list price is $1999, I looked it in SQL*PLUS and saw its image bitmap (long string) includes a "300" inside, so I believe the "default all columns search" treat image as regular string.
How can I avoid the image bitmap search included in IR? This bitmap strings are very long for each image and can EASILY match searching conditions for something like PRODOUCT DESCRIPTION, PRODUCT PRICE for our products data( about 25000)? thanks
sean

Sean / Russell,
Thanks for reporting this, it's certainly a bug.
By the way, the search is performed in SQL, on whatever column values are being displayed (run the page in debug mode to see the full SQL). So in the case of the sample application, it is not matching the image bitmap, but the image size, which is selected in the SQL. The bug is that the full search should not include columns which have filtering disabled or one of the special image format masks. We'll try to fix this for an upcoming patch.
Thanks,
Marco

New Masthead with a built-in search :: questions

I have created a new Page (2-column, wide and narrow) and in that Page I added my headerm iView and my search iView - header in the wide column, search in the narrow.
In my portal Framework, I made the existing header and the toolarea with search not visible. Effectively making the default masthead and toolarea go away.
I then added my new Page (new header iview with search iview built in) to the framework and positioned it in the masthead spot of the framework using the layout view.
My problem is that there is a visible border/padding/gaps between the header iView and the search iView. If my masthead area were all white (background color) this would not be an issue, but I am doing a similar gradient fade (like here at SDN) so these gaps do not look good.
I have set the "Show Padding Inside" property in all iView and the page to "NO" - this did not get rid of the gaps.
<a href="http://www.midnighttoast.com/images/mastheadWithSearch.gif">Example</a>
I believe the issue lies in the Page - that it has these gaps in it and they cannot be turned off through properties or other standard interface options. Can anyone help me get rid of the gaps in my masthead?
Thanks!

Hi Tony,
I don't have an exact answer for you but I may be able to point you to something that would help. If you are on NetWeaver 04 SPS14 or higher, there is new layout capabilities using tag libraries. Here is the link to the documentation. http://help.sap.com/saphelp_nw04/helpdata/en/42/ea3a29b28e1bcae10000000a11466f/frameset.htm
I have not used them but I have seen the results from people who have. They tell me you can change just about anything. Maybe someone with some experience will post and give you more info.
Good Luck.

Index Multiple Column of Multiple Tables

Hi All,
I would like to know how to create a index which can search through all column in my database tables. Eg: I have 30
tables and every tables have around 10 columns. I want to create a index which can search through the columns in
these tables.
I know that User_DataStore can helps in create multiple column search across multiple tables. But in my case the BLOB
created will be very huge. Any work around? I mean is there any solutions like concatenated datastore?
Thank You.
Regards,
LG Tan

Hi,
I figured out how to do this today. The first thing is that the type of index you need is a USER_DATASTORE.
The idea behind this type of index is pretty straight forward but the documentation does a very good job of not drawing attention to just how powerful it is.
The idea behind a USER_DATASTORE is that you can write your own stored procedure to extract the data that you want to index and return it to the indexer. Take an example where you have a master table which contains enough information to allow you to find associated data in other tables i.e. a shared key. The idea is that when you set up a USER_DATASTORE index, you specify the name of a stored procedure that the indexer will call for each row in the master table. The stored procedure has one input and one output parameter, rowid (in) and clob (out).
When the index is created, the stored procedure you specify is, as I said above, called for each row in the master table. Your stored procedure uses this ROWID to extract the shared key (this can be anything you want) from the master table and uses this to build the necessary SELECT statement to retrieve the related data from the other tables. The rest of the stored procedure simply appends the data returned from your select statement to the return CLOB. The indexer then indexes the inforamation in this CLOB and discards the data.
The index can of course only return hits against the master table. It's up to your application to extract shared key from the returned row(s), bind to the other tables and present the results.
You will find a basic example of how to implement USER_DATASTORES in the Oracle Text Reference Guide (http://download.oracle.com/otndoc/oracle9i/901_doc/text.901/a90121.pdf). Feel free to email me if you want some example code.

Search does not connect to Itunes store

I'm new to Itunes and downloaded Itunes 10.5.1. When I attempt to use the manual search function for music, the software attempts to connect to the Itunes store and then times out. However, when I tune on the column search, I'm able to call up listings from the store. I would like to use the manual search since I'm not sure of the category for some of the songs that I want. I've tried deleting and reloading the software three times and have tried other fixes suggested on the Apple website including the System Configuration Utility, using Safe Mode, creating a new Windows user account, etc. I haven't received an answer back from the Apple support folks yet. Any ideas?

Hi,
To solve this you must update your studio. In lower studio versions (PlanViz) does not allow "unknown" XML tags sent by higher version servers. A fix for this issue was made so that PlanViz parser can simply skip unknown tags.
Please go to version 74, if possible.

Hi! can any1 pls let me know how to create a look up table in labview and use that in the vi.

hello !
i have no idea how to build a lookup table(as v use in microcontroller) in labview and use that in vi.pls help me
txs

Solved!
Go to Solution.

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

How to use database look up table function in xsl mapping

Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,
