How to find a column name in tables
Hello Guys,
I need to find a column name "company_id"
in all the tables in my schema. How can i dont this?
Is there any view that search for coulmns in a table. Please help.
Regards, Imran
Questions about the dictionary are best answered by querying DICT.
In this case
select * from dict where table_name like '%COL%'
Alternatively you can look in the Oracle reference manual for your version.
The information is online, there is little need to ask around here.

How to get the column name and table name from xml file
I have one XML file, I generated xsd file from that xml file but the problem is i dont know table name and column name. So my question is how can I retrieve the data from that xml file?
Here's an example using binary XML storage (instead of Object-Relational storage as described in the article).
begin
dbms_xmlschema.registerSchema(
schemaURL => 'my_schema.xsd'
, schemaDoc => xmltype(bfilename('TEST_DIR','my_schema.xsd'), nls_charset_id('AL32UTF8'))
, local => true
, genTypes => false
, genTables => true
, enableHierarchy => dbms_xmlschema.ENABLE_HIERARCHY_CONTENTS
, options => dbms_xmlschema.REGISTER_BINARYXML
end;
genTables => true : means that a default schema-based XMLType table will be created during registration.
enableHierarchy => dbms_xmlschema.ENABLE_HIERARCHY_CONTENTS : indicates that a repository resource conforming to the schema will be automatically stored in the default table.
If the schema is not annotated, the name of the default table is system-generated but derived from the root element name :
SQL> select table_name
2 from user_xml_tables
3 where xmlschema = 'my_schema.xsd'
4 and element_name = 'employee';
TABLE_NAME
employee1121_TAB
(warning : the name is case-sensitive)
To annotate the schema and control the naming, modify the content to :
<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb">
<xs:element name="employee" xdb:defaultTable="EMPLOYEE_XML">
<xs:complexType>
Next step : create a resource, or just directly insert an XML document into the table.
Example of creating a resource :
declare
res boolean;
doc xmltype := xmltype(
'<employee>
<details>
<emp_id>1</emp_id>
<emp_name>SMITH</emp_name>
<emp_age>40</emp_age>
<emp_dept>10</emp_dept>
</details>
</employee>'
begin
res := dbms_xdb.CreateResource(
abspath => '/public/test.xml'
, data => doc
, schemaurl => 'my_schema.xsd'
, elem => 'employee'
end;
The resource has to be schema-based so that the default storage mechanism is triggered.
It could also be achieved if the document possesses an xsi:noNamespaceSchemaLocation attribute :
SQL> declare
2
3 res boolean;
4 doc xmltype := xmltype(
5 '<employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
6 xsi:noNamespaceSchemaLocation="my_schema.xsd">
7 <details>
8 <emp_id>1</emp_id>
9 <emp_name>SMITH</emp_name>
10 <emp_age>40</emp_age>
11 <emp_dept>10</emp_dept>
12 </details>
13 </employee>'
14 );
15
16 begin
17 res := dbms_xdb.CreateResource(
18 abspath => '/public/test.xml'
19 , data => doc
20 );
21 end;
22 /
PL/SQL procedure successfully completed
SQL> set long 5000
SQL> select * from "employee1121_TAB";
SYS_NC_ROWINFO$
<employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceS
<details>
<emp_id>1</emp_id>
<emp_name>SMITH</emp_name>
<emp_age>40</emp_age>
<emp_dept>10</emp_dept>
</details>
</employee>
Then use XMLTABLE to shred the XML into relational format :
SQL> select x.*
2 from "employee1121_TAB" t
3 , xmltable('/employee/details'
4 passing t.object_value
5 columns emp_id integer path 'emp_id'
6 , emp_name varchar2(30) path 'emp_name'
7 ) x
8 ;
EMP_ID EMP_NAME

How to rename a column name in a table? Thanks first!

SQL> alter table student drop column age ;
but I found the following error
ORA-00905: 缺少关键字 (Lack of Key word)
I have oracle enterprise edition 8.0.5 installed at windows 2000
thank you
And I want to know how to rename a column name in a table?
thanksIn Oracle 8i, your syntax would have worked. However, if I
recall correctly, in Oracle 8.0, you can't rename or drop a
column directly. One way to get around that problem is to
create another table based on a select statement from your
original table, providing the new column name as an alias if you
want to change the column name, or omitting that column from the
select statement if you just want to drop it. Then drop the
original table. Then re-create the original table based on a
select statement from the other table. Then you can drop the
other table. Here is an example:
CREATE TABLE temporary_table_name
AS
SELECT age AS new_column_name,
other_columns
FROM student
DROP TABLE student
CREATE TABLE student
AS
SELECT *
FROM temporary_table_name
DROP TABLE temporary_table_name
Something that you need to consider before doing this is
dependencies. You need to make a list of all your dependecies
before you do this, so that you can re-create them afterwards.
If there are a lot of them, it might be worthwhile to do
something else, like creating a view with an alias for the
column or just providing an alias in a select. It depends on
what you need the different column name for. -

Kishore PHey john,
My requirement is as follows
I have created a Rank for Total sales by Region wise i.e RANK(SUM(Dollars By Region)) in a pivot table.
My pivot table looks like this
COLUMN SELECTOR: TOTAL US , REGION , DISTRICT , MARKET
---------------------------------------------------- JAN 2009 FEB 2009 MAR 2009
RANK REGION DOLLARS DOLLARS DOLLARS DOLLARS
1 CENTRAL 10 20 30 40
2 SOUTHERN 10 30 30 70
3 EASTERN 20 20 20 60
4 WESTERN 10 20 30 40
When i select the District in column selector
Report has to display rank based on Total Sales by District. i.e
------------------------------------------------- JAN 2009 FEB 2009 MAR 2009
RANK DISTRICT DOLLARS DOLLARS DOLLARS DOLLARS
for this i need to change the fx of rank i.e RANK(SUM(Dollars By Region)) to RANK(SUM(Dollars By District)) and fx of Region i.e Markets.Region to Markets.District dynamically.
so , i need to capture column name of the value selected from the column selector and dynamically i need to update the fx 0f RANK & fx of region.
do you have any solution for this?

How to use the column names generated from Dynamic SQL
Hi,
I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
Please find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
OPEN insert_csr FOR CASE
WHEN v_where IS NOT NULL
THEN 'SELECT '
|| v_select
|| ' FROM '
|| v_table
|| v_where
|| ';'
ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
END;
LOOP
v_ins_query :=
'INSERT INTO '
|| v_ins_tab
|| '('
|| v_insert
|| ') VALUES ('
|| How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;
Please help me out with the above problem.

I Built the statement as required but i need the column list because the first column value of each row should be inserted into one more table.
So i was asking how to fetch the column list in a ref cursor so that value can be inserted in one more table.

Then add a RETURNING INTO clause to the query to have Oracle return the first column values into a collection.

What version of oracle are you using? If it is 9i,

if it is 8i or earlier, you can create a view with the required names.
