Decode possible without column name?

Hi,
I am trying to reformat text using decode as follows:
SELECT DECODE('a1a1','a','X','Z') FROM DUAL;
in order to convert 'a1a1' inro 'XZXZ'
However, this didn't work, so I tried:
SELECT DECODE('a1a1' as VARIABLE,'a','X','Z') FROM DUAL;
Any ideas what is the best way to do it?
I can do it using TRANSLATE, but that only applies one substitution, whereas I need two.

Decode is possible without a column name but it is looking for exact matches, ie if ('a1a1') = 'a' then 'X' else 'Z'In your example you can use translate:
select translate('a1a1','a1','XZ') from dual;
TRAN
XZXZor a nested translate
select translate(translate('a1a1','a','X'),'1','Z') from dual;
TRAN

Why all the ugly upper case? You do realise that NO programming standard, ranging from Java and .Net, to C/C++ and Ada (of which PL/SQL is an implementation of), use upper-case-for-reserved-words as a standard.
The easiest and simplest way to address your requirement is as follows:

JTable can't display column names and scroll bar in JDialog !!

Dear All ,
My flow of program is JFrame call JDialog.
dialogCopy = new dialogCopyBay(frame, "Bay Name Define", true, Integer.parseInt(txtSourceBay.getText()) ,proVsl ,300 ,300);
dialogCopy.setBounds(0, 0, 300, 300);
dialogCopy.setVisible(true);        Then,I set the datasource of JTable is from a TableModel.
It's wild that JTable can diplay the data without column names and scroll bar.
I have no idea what's going wrong.Cause I follow the Sun Tutorial to code.
Here with the code of my JDialog.

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Maybe something like this is what you are looking for or at least will give you some ideas.
        public static DataSet MaterializeDataSet(string _connectionString, string _sqlSelect, bool _returnProviderSpecificTypes, bool _includeSchema, bool _fillTable)

Column name of custom columns is possible of translating automatic

In SharePoint 2013 is possible of translating automatic the column name of custom columns with machine translation services or it is necessary create resource files or source site and target site?

Hi,
When you create a column, the name you enter is just a constant string. SharePoint does not do translation based on known words. Internationalization is based on resource files.
Here are the steps I would take for creating international-able columns through the browser:
Create the column with the name you want as the internal name (ie, no spaces or symbols to avoid
_x0020_ and other encoding replacements).
Edit the column by changing the column name to a resource string that you know if defined in each language you want to support.
Here are similar posts, you can use as a reference:

GROUP BY Workweek, Type)
This sql query above does not run properly, gives invalid column name error. However, the entire select statement surrounded by the () works. There must be an error in the first 4 lines someplace, but I do not see it.

Assuming type is a string, I assume you meant
MAX( DECODE( type, 'T34', prct, NULL )) Badwhere T34 is a string literal. Otherwise, you'd need to have columns named T34, T35, and T36 in your inner select.
One note, though, it's probably a bad idea to have a column named Type. While it's legal to do so, TYPE is a keyword in SQL, so that name will at a minimum be confusing.

How to switch column names without moving song list?

Somehow I put the song names under the column labled "Artist" and the artist under "Names".
How can I change these column titles without having to retype each song title and artist under the correct column names?
Thanks

Why would you mess up song info like this?

Is there a way to change fixed width Flat file connection manager to delimited without losing all the column names ?

Is there a way to change fixed width Flat file connection manager to delimited without losing all the column names ?

Unfortunately not as it is a quite dramatic change causing the metadata being refreshed. I would try to open though the package file in a text editor and find them before doing the change, then after you made the change to the FF connector try to reconstitute
/ replace the autimatically generated columns with the old names.

Inserting values for all records except 1 or 2 column ,without specify column names.,?

Hi,
for example, in student table i am having 1000 columns, column names like(id ,name,class, dept,etc,.).
i want to insert 998 fields to department table from student tables except(id,class).
i don't want to mention all column names in the insert command,
is there any possibilities to filter the column names in insert command like (EXCEPT, NOT IN).
Thanks in advance..

Is it possible to return column names?

Hi!
Is it possible to return column names of a select statement?
Let's say I have table with the following columns:
Col1
COl2
Col3
And I have a select statement like this:
Select * from XX
Is it then possible either through SQL or PL/SQL to return the column names?

If you are looking at column names for a particular table,
then you can query aganist the sys.User_Tab_Columns.
here is the piece of code.
SELECT Column_Name
FROM Sys.User_Tab_Columns
WHERE Table_Name = 'TABLENAME';
Remember TABLENAME is the name of the table in CAPITAL letters.
You can use this in SQL or PL/SQL code.
You can also use the ALL_Tab_Columns but then you have add
another AND condition, because, the there may be a same table name for different users. so one has to use the owner Column in your query.
SELECT Column_Name
FROM All_Tab_Columns
WHERE Table_NAME = 'TABLENAME'
AND OWNER = 'TABLE_DESIRED_OWNER';

Is it possible to create a Synonym with different column names

Hi,
I want to create a Synonym with different columns names (Columns not in original table) . I am not sure if this can be done . Any suggessions...
Thanks in advance....

Synonyms are not limited to tables. Accroding to the SQL Reference, a synonym is:
an alternative name for a table, view, sequence, procedure, stored function, package, materialized view, Java class schema object, user-defined object type, or another synonym.
In fact, synonyms are not even validated until they are used:
SQL> create synonym my_synonym for table_which_does_not_exist;
Synonym created
SQL> select * from my_synonym;
select * from my_synonym
ORA-00980: synonym translation is no longer valid

Bulk Load data without specifying column names in control file

I am totally new to the world of Oracle databases and am having some trouble doing some basic data imports from a csv file. I have a large amount of data in an excel spreadsheet (a couple hundred columns by varying numbers of rows from 2- several thousand) which I want to import into my Oracle 11g Database. Currently I am trying to use sql loader and specify the import syntax in the control file. From the examples I've seen so far, it seems you must specify the columns individually for what you are importing. This is simply not reasonable for several hundred columns of data.
Is there sql loader syntax (or a better method all together) to import a comma delimited csv or excel spreadsheet into an oracle database where it automatically generates a table and columns based on the data in the target import file? Even if I must first create the table in the database, my key issue is being able to generate the column names during import to match the column headers in the import file. I appreciate any help you could provide.
FYI here is my first meager attempt at importing a comma delimited csv, here is my ctl file:
load data
infile 'C:\filepath\mock_data.csv'
into table allData
fields terminated by "," optionally enclosed by '"'
It says Syntax error at line 4. Expecting "(", found end of file.
I suspect there is more at issue here than a missing "("

You have to create the control file to map to the table.
Since you would already have created the tables, you could generate the controlfiles based on the table structures.
See the "unloader.zip" file under the Files link at http://asktom.oracle.com
-- it has scripts to create unload a table to a flat file and to create the SQLLoader controlfile to reload that data to another target database. It would be the second set of scripts that you can use.

Nested table - how to reference internal column without a name??

Hi guys, I've a question regarding nested tables - Ive searched around and cant find an answer.
Heres my sample code :
CREATE OR REPLACE TYPE scotttype AS table of number;
create table scott1 (col_a varchar2(10), col_b scotttype) nested table col_b store as col_b
insert into scott1 values ('onetwo',scotttype(1,2))
insert into scott1 values ('threefour',scotttype(3,4))
select t1.col_a, column_value col_b
from scott1 t1, TABLE(t1.col_b) t2
insert into table(select s.col_b FROM scott1 s WHERE s.col_a = 'onetwo')
values (5);Ok, so that seems fine.
If I want to do an update or delete though, how can I reference col_b as the nested table doesnt have a column name ?
Ie :
update table(select col_b from scott1 where col_a = 'onetwo') col_b
set col_b.XXXXX = 6
where col_b.XXXXX = 5won't work - so what do I put in place of the XXXXX ???
I'm sure its simple, but I can't find it!
Thanks all

SQL> select t1.col_a, column_value col_b
2 from scott1 t1, TABLE(t1.col_b) t2;
COL_A           COL_B
onetwo              1
onetwo              2
threefour           3
threefour           4
onetwo              5
SQL> commit;
Commit complete.
SQL> update table(select col_b c1 from scott1 where col_a = 'onetwo') t1
2 set column_value = 6
3 where column_value= 5;
1 row updated.
SQL> commit;
Commit complete.
SQL> select t1.col_a, column_value col_b
2   from scott1 t1, TABLE(t1.col_b) t2;

onetwo              1
onetwo              2

Can I use bind variable instaed of writing static COLUMN Name

Hi , I am having a table containing id and column names, the data is stored against that id in other tables. Now I wish to update data into another table so that it goes into apppropriate column without using decode function.
I am trying to do this:
EXECUTE IMMEDIATE 'update TEST set :1 = :2
where PROJECT_ID= :3 and UNIQUE_ID= :4' using P_DEST_COLUMN, P_TEXT_VALUE, P_PROJ_ID, P_TASK_UID;
the values P_DEST_COLUMN, P_TEXT_VALUE, P_PROJ_ID, P_TASK_UID are populated using a cursor in PL/SQl
Is this statement valid? If not can you tell me how to do it as I am getting some error I am unable to comprehend.
thanks
Rishabh

Column names cannot be substituted at run-time as bind variables. If you need to specify the column name at run-time, you'd need to construct a new string and execute that string dynamically, i.e.
EXECUTE IMMEDIATE 'UPDATE test SET ' || p_dest_column || ' = :1 ' || ...From a data model standpoint, storing column names as data elements in another table is generally a rather poor idea. It's likely to make ad-hoc reporting nearly impossible and to cause a lot more parsing than would otherwise be required.

Decode possible without column name?
