How do i know in how many tables particular column exists

i want to know in how many tables a particular column exists..
what i mean is
let us assume that there is a Column ABC in table SERVICE.
this particular ABC column is there in some other tables REQUEST,HHG,SS.... and so on
what exactly my query is..
how can i know where all in the database the column ABC is used..
i mean i want to get all the table names using this column ABC.
hope i am clear with my doubt..
thanks for the replies in advance

If I understand the question
SELECT owner, table_name
FROM dba_tab_cols
WERE column_name = 'ABC'Of course, depending on the requirements, you could use the ALL_TAB_COLS or USER_TAB_COLS tables as well.

Return the rows of the table where a column contains a specific value first

I want my query to return the rows of the table where a column contains a specific values first in a certain order, and then return the rest of the rows alphabetized.
For Example:
Country
ALBANIA
ARGENTINA
AUSTRALIA
CANADA
USA
Now i want USA and CANADA on top in that order and then other in alphabetized order.

If you store your "top" countries in a table you can then simply do something like...

Compare tables in two schemas for the table with particular column & value

Hello All,
I have a query to find out the list of table from a given schema to extract all the tables having a search column .
ex :
SELECT OWNER, TABLE_NAME, COLUMN_NAME FROM
ALL_TAB_COLUMNS WHERE OWNER='<SCHEMA_NAME>'
AND COLUMN_NAME='<COLUMN_NAME>'
I want to compare two schemas for the same above query .
Can we wirte a query on this - I am using SQL DEVELOPER , which has menu item - TOOL - database differneces to find the diffenence between two schemas but my requirement is to find the differences in two schemas for all the tables matching for a particular column ( as given in quer).
Appreciate your help.
thanks/Kumar

Hi, Kumar,
This is the SQL and PL/SQL forum. If you have a question about SQL Developer, then the SQL Developer is a better place to post it. Mark this thread as "Answered" before starting another thread for the same question.
If SQL Developer has a tool for doing what you want, don't waste your time trying to devise a SQL solution. The SQL Developer way will probably be simpler, more efficient and more reliable.
If you do need to try a SQL solution, then post some sample data (CREATE TABLE and INSERT statements for a table that resembles all_tab_columns; you can call it my_tab_columns) and the results you want from that data.

Table.rows.find() returns null in a table where the row exists.

Hi...
I am working in a Project in Visual Studio 2013 where I have to read an Excel report related with a list of business opportunities. Some of the Fields that are involved in it are: Opportunity ID, BU, Account, close date, Account Manager,
Total Value and so on. As soon as I get the conection with the Excel Report, I fill a DataTable and declare the columns [Opportunity ID] and [BU] as my Primary Keys. In that way, an Opportunity value may have one o more rows
with different BU code each of them. In consequence, you can define one row in the table if you specify the [Opportunity ID] and the [BU] values.
My problem starts when I try to get information of those rows that have an specific value of [Opportunity ID]. For that situation I make a "foreach" structure where I check the BU codes that are involved with that Opportunity. So
I use the Find() Method to get the information of the row specified by the Opportunity ID and BU. The first time it goes to find the information it gets the results successfully but in the next cycle changing just the [BU] using the same [Opportunity
ID] value, the find() method returns a "null" and I do not know why because I am sure that the row exists in the table. I have verified the "Unique" property for the [Opportunity ID] and [BU] columns (which are
my primary keys) and they are in false which is OK.
I share the code that I am using...
Hope someone can help.
Thanks.
Alfmar.
void ObtenTotalesxBUs(string Opportunity, string[] BUs, Object[] TotalBUs, Object[] ExpTotalBUs)
ArrayList TotalesBUs = new ArrayList(); //Required information from the row.
ArrayList ExpTotalesBUs = new ArrayList(); //Required information from the row.
foreach(string businessUnit in BUs)
Object[] LlaveBusqueda = { Opportunity, businessUnit }; //Provide values to the Primary Keys.
DataRow RenglonInfo = null;
RenglonInfo = TablaFunnel.Tabla.Rows.Find(LlaveBusqueda); //Find method receives the Primary Keys values. Here is where I have a "null" in return the second time changing just the [BU] field.
TotalesBUs.Add(RenglonInfo["Total"]); //Get the required information from the row.
ExpTotalesBUs.Add(RenglonInfo["Expected Total Value"]); //Get the required information from the row.
TotalBUs = TotalesBUs.ToArray();
ExpTotalBUs = ExpTotalesBUs.ToArray();}

Hi Viorel..
Thanks a lot for you help.
I am absolutely sure that the second ítem of BU is valid and exist in the table because I tried to make a "Select" statement in the table providing the values of [Opportunity ID] and [BU] and I get the expected record. So, why is not
working using Find() with the defined Primary Keys???
I tried this in order to test that the record exists...
if(RenglonInfo == null)
string strSelect = "[Opportunity ID] = '0000218256' AND [BU] = 'SFW'";
RenglonInfo2 = TablaFunnel.Tabla.Select(strSelect);

How to update column values in a table where that column is referring to different tables

i have a table Order it has columns
OrderID, Name, Total
1            trade   value populated from i.e. tradeorder table
2            fixed   value is populated from fixedorder table
3            annual value populated from another table
I m thinking of creating function for every order id to call those tables..
and there are many insertions taking place in order table ,,at the moment its 20 rows ..
kindly provide your suggestions

You can group rows in order table and update the set of row from the specific table. For instance
UPDATE [ORDER] SET [TOTAL]=B.[TOTAL] FROM [ORDER] A INNER JOIN [TRADEORDER] B ON A.ORDERID=B.ORDERID WHERE A.NAME='TRADE'
UPDATE [ORDER] SET [TOTAL]=B.[TOTAL] FROM [ORDER] A INNER JOIN [FIXEDORDER] B ON A.ORDERID=B.ORDERID WHERE A.NAME='FIXED'
UPDATE [ORDER] SET [TOTAL]=B.[TOTAL] FROM [ORDER] A INNER JOIN [ANOTHERTABLE] B ON A.ORDERID=B.ORDERID WHERE A.NAME='ANNUAL'

Particular column as control in table

Dear All,
Is there any way to make a particular column in a table as control and rest indicators?
I am creating a table where in 1 column i display the speed which is calculated by the program and in the next column the user wants to add the distance.
So, in the table i want the column representing Speed should act as an indicator and the Distance Column should behave as a Control as the user manually has to enter the distance.
how is this possible?
Thanks,
Ritesh

Hello ritesh024,
The attached vi is a small exemple of "Control column" and " Indicator column".
This Vi computes the hypothenuse of a triangle according to the big and small side lengths.
It is composed of a table where first column is small side, second bigside, and the third is hypothenuse calculation.
When the table changes, the hypothenuse is computed according to big and small side lengths.
The hypothenuse column could be considered as "indicator" as you cannot change the value without triggering a new computation
Hope this helps!

Sql join on two tables where column like another column

hi all,
been trying to get the results from a join between two tables where one column is like another one.
table1 (nameA) examples: black2, green1
table2 (nameB) example: black2.location.uk.com, green1.location.uk.com
so for example I want to match all those in table1 with black2 to the column in table2 that begins with black2 and so on if you see what im trying to get at!
my sql so far:
select * from schema.table1 a
join schema.table2 b
on a.nameA like concat('%', b.nameB, '%'); but it errors:
ORA-00909: invalid number of arguments
00909. 00000 - "invalid number of arguments"
Any help or advice would be greatly appreciated, thankyou!

Either of these should do it...
select * from schema.table1 a
join schema.table2 b on a.nameA like '%'||b.nameB||'%';or
select * from schema.table1 a
join schema.table2 b on instr(b.nameB,a.nameA) > 0

Selection in table with Master Column

Hi,
can anybody explain me how selection works in table with MasterColumn (TreeByNestingTableColumn)?
I've created a table with several columns and the "master" one behaves differently from others.
First of all, leaf elements of master column are not clickable (i.e. I don't receive notification "onLeadSelect" from the table, when user clicks in the cell of leaf element of the column). With expandable elements I receive loadchildren event and can react on selection.
I'm using TextView as cell editor, will try LinkToAction, may be it will resolve situation, but it's rather workaround as solution
Second, getLeadSelection doesn't work anymore for the table - it works with indexes of top level elements only.
However onLeadSelect action brings me selected row number, which I somehow should map to the tree.
I.e. when I get "25" as selected element, I recursively traverse context node to find 25th element. Which is rather slow operation as for any selection I have to reiterate whole structure and I hope that visual appearance is similar to context element order.
May be there is simplier ways to get selected element by its index in "flat" list?
And one another strange thing: first click on the table sends me onLeadSelect "0", but highlight points to the element user clicked - not necessary first one.
Context node is "single" selection, initLeadSelect=true,
selection = 0..1 (with 1..1 setTreeSelection doesn't work - method I want to use to be able to select a node in hierarchy on my own)
all quite similar to other tables I have, which works well. Just the problems with the table, where Master Column is used.
Thank you!
Best regards,
Nick

>Valery's proposal was to perform reverse traverse from current element to root and summarize parent element indexes.
It seems to work:
in method, which sets selection I applied
// we need to know index of the element not in whole context, but in scope of table-relevant node
int index = getIndexInContext(selElement, wdContext.currentXXXElement());
IContextElement curContext = wdContext.currentContextElement();
int firstVisibleRow = curContext.getTableFirstVisibleRow();
int visibleRows = curContext.getTableVisibleRows();
if (index < firstVisibleRow || index > firstVisibleRow + visibleRows) {
curContext.setTableFirstVisibleRow(index);
and method getIndexInContext looks as:
    private int getIndexInContext (IWDNodeElement element, IWDNodeElement root) {
          int index = element.index();
          if (element == root) {
               return index;
          IWDNodeElement parent = element.node().getParentElement();
          if (parent == null) {
// do whatever you like here for error diagnostic
               myMsgMgr.reportException("Internal Error: getIndexInContext - element is not under passed root", false);
               return 0;
          // +1 - every level adds 1 (otherwise indexes of first children of hierarchy will be 0)
          return index + getIndexInContext(parent, root) + 1;

Query to list tables with a particular column name in a schema!!

Is there any way to know?
Thanks in advance.

You can query the data dictionary views to get this information.
For example
untested
select table_name
from user_tab_columns
where column_name = 'my particular column name';There is also all_tab_columns and dba_tab_columns. Both of which would include the schema name.

Wanting data from a table without a particular column

I need the data from a table, except the data for a particular
column. I don't want to write the select list, as it would be
too clumsy for a large table. Can anybody suggest a solution. I
can certainly create a view, but I don't want that.

Hi,
Try this select Statement.
set haeding off
set feedback off
spool file.sql
Select 'Select ' from dual;
Select Column_name || ',' from all_tab_columns Where table_name = 'EMPLOYEE' and Column_Name != 'DEPARTMENT_ID';
Select '1' from dual;
select 'From Employee;' from dual;
Spool off

Deleting from multiple tables where few tables have same column name

Hi,
I am new to PL/SQL and need some help. I need to delete data older then X years from some 35 odd tables in my schema and out of those tables 25 tables have same column name on which i can have my "where" clause and rest 10 table have different table names. I am doing something like this :
declare
table_list UTL_FILE.FILE_TYPE;
string_line VARCHAR2(1000);
tables_count number:=0;
table_name VARCHAR2(400);
column_name VARCHAR2(400);
BEGIN
table_list := UTL_FILE.FOPEN('ORALOAD','test7.txt','R');
DBMS_OUTPUT.PUT_LINE(table_list);
LOOP
UTL_FILE.GET_LINE(table_list,string_line);
table_name := substr(string_line,1, instr(string_line,'|')-1);
column_name := substr(string_line, instr(string_line,'|')+1);
DBMS_OUTPUT.PUT_LINE(table_name);
DBMS_OUTPUT.PUT_LINE(column_name);
IF column_name = 'SUBMISSION_TIME' THEN
delete from :table_name where to_date(:column_name)<(sysdate-(365*7));
ELSE
delete from || table_name || where ( || to_date(column_name) || ) <(sysdate-(365*7));
END IF;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(table_list);
DBMS_OUTPUT.PUT_LINE('Number of Tables processed is : ' || tables_count);
UTL_FILE.FCLOSE(table_list);
END;
WHERE the text file "text7.txt" contains list of table name and column names separated by a pipe line. But when I execute the above proc it gives error "invalid table name".
Can something like this be done or is there any other way to execute this task of deletion from 35 tables.
Thanks.

Thanks for replies. I don't know what I am doing wrong but still not getting this damn thing work...This is the proc i am running now :
declare
table_list UTL_FILE.FILE_TYPE;
string_line VARCHAR2(1000);
tables_count number:=0;
table_name VARCHAR2(4000);
column_name VARCHAR2(4000);
code_text VARCHAR2(2000);
BEGIN
table_list := UTL_FILE.FOPEN('ORALOAD','test7.txt','R');
LOOP
UTL_FILE.GET_LINE(table_list,string_line);
table_name := substr(string_line,1, instr(string_line,'|')-1);
column_name := substr(string_line, instr(string_line,'|')+1);
IF column_name = 'SUBMISSION_TIME' THEN
DBMS_OUTPUT.PUT_LINE('do nothing');
ELSE
code_text:= 'begin delete from'|| (table_name) ||'where to_date' || (column_name) || '<(sysdate-(365*7))';
Execute Immediate code_text;
END IF;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(table_list);
DBMS_OUTPUT.PUT_LINE('Number of Tables processed is : ' || tables_count);
UTL_FILE.FCLOSE(table_list);
END;
But it gives following error :
" ORA-06550: line 1, column 51:
PL/SQL: ORA-00933: SQL command not properly ended
ORA-06550: line 1, column 7:

How to Determine Whether Columns Exist in a Table

Greetings,
Because of customizations to our product, certain database table structures vary between different client installations. Hence, in the code, I need to determine whether two columns exist in a certain table, in order to apply some business logic.
Please suggest a way for me to determine whether two named columns appear in a specific table. In other words, for example, I need to discover whether both columns SAL_GRADE and BONUS appear in the EMP table, or not. Only if both columns are defined, can I apply my business logic.
Thanks,
Avi.

Avi,
Like this ?
SQL> declare
2    l_count number;
3 begin
4    select count(*)
5      into l_count
6      from user_tab_columns
7     where table_name = 'EMP'
8       and column_name in ('SALGRADE','BONUS')
9    ;
10    if l_count = 2
11    then
12      dbms_output.put_line('Both columns exist, so apply business logic');
13    else
14      dbms_output.put_line('One or both columns are missing, so don''t apply business logic');
15    end if;
16 end;
17 /
One or both columns are missing, so don't apply business logic
PL/SQL-procedure is geslaagd.Regards,
Rob.

How to test if a column exists in a table

Hello,
Using SQL or PL/SQL how do I test if a column exists in a table. For example,
if column_aa exists in table_1
then do this....
else do that....
Thank you.

Set ServerOutput On;
CREATE Table a_Test (
Col1 NUMBER
, Col2 NUMBER )
DECLARE
lnCol1 NUMBER ;
lnCol7 NUMBER ;
PROCEDURE TestColumn( acColName IN VARCHAR2 )
IS
lnColX NUMBER ;
NoColumnExists EXCEPTION;
PRAGMA EXCEPTION_INIT(NoColumnExists, -904);
BEGIN
EXECUTE IMMEDIATE
'SELECT Max('|| acColName||') FROM a_Test WHERE RowNum = 0'
INTO lnColX ;
DBMS_OUTPUT.Put_Line('Column: '||acColName||' exists.');
EXCEPTION
WHEN NoColumnExists THEN
DBMS_OUTPUT.Put_Line('Column: '||acColName||' NOT exists.');
WHEN Others THEN
DBMS_OUTPUT.Put_Line( SqlCode ||' '||SqlErrM );
END
BEGIN
DBMS_OUTPUT.Enable ;
TestColumn( 'Col1') ;
TestColumn( 'Col2') ;
TestColumn( 'Col7') ;
END
DROP Table a_Test;
