Column order in a select * query

Suppose I have 256 columns in a table and if I query select * from tablename ,what will the column order in the result.Will this be always same as order as in created statement?

If the columns were all in the original CREATE TABLE statement, then, yes, the ordering of columns in SELECT * FROM will match the order from the CREATE TABLE statement.
If columns were added after the initial create, then the original columns will come first (in their order) and then the added columns (in their order), etc.
In the real world, it is a very bad practice to use SELECT * and have expectations about the ordering of the columns. Consider this scenario:
Table T was created and implemented in production a year ago with columns A, B, C
A project started up three months ago and added column D but the project is stalled in development. So in development T had columns A, B, C, D
Later, another project started up and added columns E and F. Unlike the other project, it has progressed to Test. and Production. So in Development the table has columns A, B, C, D, E, F. In test and production the table has columns A, B, C, E, F.
Now that stuck project has progressed to Test and Production. Now T has columns A, B, C, E, F, D in test and production but still A, B, C, D, E, F in development.
Until someone notices and decides to fix it (where and how?)
Be very, very careful about using SELECT *.

Order by in select query

Hi guys
i am getting problem in my select query which is creating one long string, it is working fine without order by but when i run this with order by it get hanged. this query using on function to concatenate multiple strings in one string as well
Please help me what i am doing wroing.

Not sure about why it's only hanging on order by but looks like your query causing full table scan because of this in WHERE clause:
and pcb.st||jou.st||pcp.st='1'
I would change it to something like:
and ((pcb.st='1' and jou.st = '' and pcp.st = '') or (jou.st='1' and pcb.st = '' and pcp.st = '') or (pcp.st='1' and jou.st = '' and pcb.st = '') )

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.

Default in "order by" in select query may be different in 11g from 10g

Hi, I am wondering if when you are querying a table in 11g and you use the order by clause and there is more than one occurrences with the same values in the order by, if the 11g default is different than from 10g. For instance.
DECLARE MHBulk CURSOR FOR
select invoice_nbr,
               customer_nbr,
                post_century,
                post_yymmdd,
     from CUSTOMERS
     where customer_nbr = 1234
     order by
           post_century,
           post_yymmdd;
If you have more than one occurrence of the same customer_nbr, post_century, and post_yymmdd it looks like the default order for how 11g retrieves the records is a bit different than the 10g default.   Does anyone know why this is?

JustinCave wrote:
In any version of Oracle, if your ORDER BY does not specify a completely unique order, the order in which ties are broken is arbitrary. Realistically, it will depend on things like the specific query plan chosen, the physical order of data on disk, which parallel query slave read the row, etc. So it is subject to change within the same version of the database when, for example, a query plan changes. It is entirely plausible that the results would be returned in the same order for years and then suddenly change one day. If you care about the order of ties, you should add additional logic to the ORDER BY clause that specifies the order you want rather than assuming that there is a "default" order applied.
Upgrading to a new version of Oracle, particularly if that was done via something like exporting and importing the data so that you're changing the Oracle version and the physical order of data and various object statistics, it is not at all unusual that you would get slightly different plans and that ties would be broken differently. I wouldn't assume that there is a new "default" order, though. It's entirely possible for the order to change if the query plan changes again.

Well, what happened is we've gotten a few new customers and those customers are on Linux oracle 11g. All the other customers are on regular unix 10g. So, it sounds like we've just been lucky with the order until now. In our system we have a sequence number column which is unique and I solved this by adding that in the ORDER BY clause. I was just curious as to whether oracle had a default when it found duplicate fields in the ORDER BY clause. I can't imagine that oracle doesn't have a default like unique_session_id or something like that.

Is that important column order in a query with row_number function

Hi folks,
I am using Oracle 11g R2 on HP-UX machine.
I have 2 types of query with row_number and I think they are same but output of each of them are different. I changed only column order in query2.
Query 1 :
(SELECT
"LOOKUP_INPUT_SUBQUERY"."CONTRACT_SK" "CONTRACT_SK",
"LOOKUP_INPUT_SUBQUERY"."SIMCARD_SK" "SIMCARD_SK"
FROM (
SELECT row_number ()
OVER (
PARTITION BY "R_CON_SUBS_SIMCARD_LK".
"CONTRACT_SK"
ORDER BY
"R_CON_SUBS_SIMCARD_LK"."START_DATE" DESC,
"R_CON_SUBS_SIMCARD_LK"."SEQ_NUM" DESC NULLS LAST) /* EXPRESSION_3.OUTGRP1.SIRA */
"SIRA",
"R_CON_SUBS_SIMCARD_LK"."CONTRACT_SK" "CONTRACT_SK",
"R_CON_SUBS_SIMCARD_LK"."SIMCARD_SK" "SIMCARD_SK"
FROM "SRC_OZRDS"."R_CON_SUBS_SIMCARD_LK" "R_CON_SUBS_SIMCARD_LK")
"LOOKUP_INPUT_SUBQUERY"
WHERE ("LOOKUP_INPUT_SUBQUERY"."SIRA" = 1))
Output of this like that :
CONTRACT_SK SIMCARD_SK
1     1
1     3
1     4
1     5
1     6
1     11
1     12
1     14
1     15
1     16
Query 2 :
(SELECT
"LOOKUP_INPUT_SUBQUERY"."CONTRACT_SK" "CONTRACT_SK",
"LOOKUP_INPUT_SUBQUERY"."SIMCARD_SK" "SIMCARD_SK"
FROM (
SELECT
"R_CON_SUBS_SIMCARD_LK"."CONTRACT_SK" "CONTRACT_SK",
"R_CON_SUBS_SIMCARD_LK"."SIMCARD_SK" "SIMCARD_SK",
row_number ()
OVER (
PARTITION BY "R_CON_SUBS_SIMCARD_LK".
"CONTRACT_SK"
ORDER BY
"R_CON_SUBS_SIMCARD_LK"."START_DATE" DESC,
"R_CON_SUBS_SIMCARD_LK"."SEQ_NUM" DESC NULLS LAST) /* EXPRESSION_3.OUTGRP1.SIRA */
"SIRA"
FROM "SRC_OZRDS"."R_CON_SUBS_SIMCARD_LK" "R_CON_SUBS_SIMCARD_LK")
"LOOKUP_INPUT_SUBQUERY"
WHERE ("LOOKUP_INPUT_SUBQUERY"."SIRA" = 1))
Output of this like that:
2     874812
7     70097256
8     18734091
9     158024
10     815397739
13     22657919
19     83177779
20     82579529
22     5829949
23     35348926
25     3865978
I expected the second output, because there are lots of contract sk but there is one contract_sk in first query result. i did not get the point. What is the problem ?

I changed only column order in query2.So what else do you expect? If you order, for example, by last name, fist name don't you think rows will be returned in a different order (and therefore same row will have different row number) than ordering by first name, last name?

Changed column order not applied to interactive report

Hi,
I've changed column order for interactive report.
But it is not applied.
How can I solve this issue?
Thanks,
Guy

Hi Guy
It depends on where you have changed the column order. If you change the column order using the 'Select Columns' function when you click on the 'Wheel of Magic', then it should work.
If you are changing the column order from the Interactive Reports Attributes page then this will only affect the column order for non displayed items and the single row view.
I hope that helps

Report Does Not Follow Select Column Order

Hi all,
Apex 2.2 on 10gXE
I always encounter this problem, the display column on report does not follow the select column sequence order in the "region source".
It is very tedious clicking the up/down arrow one-by-one in the "report attributes" especially if the display columns are plenty like 40 columns.
Is there a fix/patch or alternative tips for this bug?
Thanks a lot,

This is not a bug. APEX maintains the original column order of the report. This avoids problems downstream in areas like the processing of <tt>g_fnn</tt> arrays in declarative tabular forms, where the assigned arrays are column-order dependent.
APEX 4.x fixes column ordering bugs that could lead to report corruption, and includes drag-and-drop column ordering in the new tree view in addition to the up/down arrow re-ordering.
If you really want column order to follow that in the source query, the workaround is to create a new report using the modified query.

Select query gives result in abc order instead of creation order

Hi,
I used the following command in sql command window to insert some rows to my table:
SQL>
SQL> insert into regions (Region_ID, Region_Name) values (1 , 'Zafon');
1 row inserted
SQL> insert into regions (Region_ID, Region_Name) values (2 , 'Hasharon');
1 row inserted
SQL> insert into regions (Region_ID, Region_Name) values (3 , 'Merkaz');
1 row inserted
SQL> insert into regions (Region_ID, Region_Name) values (4 , 'Jerusalem');
1 row inserted
SQL> insert into regions (Region_ID, Region_Name) values (5 , 'Hashfela');
1 row inserted
SQL> insert into regions (Region_ID, Region_Name) values (6 , 'Darom');
1 row insertedWhen I use select * query to see the table, I get the content in abc order:
SQL> SELECT * FROM REGIONS;
REGION_ID REGION_NAME
        6 Darom
        2 Hasharon
        5 Hashfela
        4 Jerusalem
        3 Merkaz
        1 Zafon
6 rows selectedHow can I get the result in the creation order (first created- first shown)?
Thanks

You can't - not unless you use a solution that you should NEVER use unless absolutely necessary.
WHY do you need to do this? You never provide a reason.
To get a result in creation order there are two requirements:
1. Use an ORDER BY when you query the table - this is the only requirement others have mentioned
2. Control and specify the creation order when you INSERT the data
Unfortunately there is only ONE way that I am aware of to implement #2 above (i.e. to control the insertion order) and that is to SERIALIZE the insertion of rows into the table. That means that only ONE user can insert rows into the table at a time perhaps by using a stored procedure to perform the insert.
In a multi-user system a USER can NOT see uncommitted data of other users. If a user uses a trigger and a SEQUENCE generator to generate ascending numbers another user can use that same trigger and sequence to generate numbers also. If the first user performs an INSERT and gets number 37 but doesn't commit a second user can perform an INSERT, get number 38 and COMMIT before the first user commits.
That means that the row with 38 was created (committed) first but has a higher sequence than the row with 37.
The best you can do is use a sequence generator to generate unique ascending numbers. Then you can query the data using an ORDER BY on the column that contains the sequence value. But, as shown above, that doesn't guarantee that the rows were actually committed in that order.
That may sound like a trivial distinction but it has a very important implication. It means that you can NOT use that sequenced column to extract data reliably for batch-type processing. For the above example supposed your batch process extracted data for values from 1 to 38 and then that first user did a COMMIT.
The next extract would be for values from 39 to 50 (or some other value) and the row with 37 would never be extracted. For the same reasons you can't use a CREATION_DATE value for such extract purposes either since you would have the same issue.

How to create a Type Object with Dynamic select query columns in a Function

Hi Every One,
I'm trying to figure out how to write a piplined function that executes a dynamic select query and construct a Type Object in order to assigned it to the pipe row.
I have tried by
SELECT a.DB_QUERY INTO actual_query FROM mytable a WHERE a.country_code = 'US';
c :=DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(c,actual_query,DBMS_SQL.NATIVE);
l_status := DBMS_SQL.EXECUTE(c);
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
FOR j in 1..col_cnt LOOP
DBMS_SQL.DEFINE_COLUMN(c,j,v_val,2000);
END LOOP;
FOR j in 1..col_cnt LOOP
DBMS_SQL.COLUMN_VALUE(c,j,v_val);
END LOOP;
But got stuck, how to iterate the values and assign to a Type Object from the cursor. Can any one guide me how to do the process.
Thanks,
mallikj2

Hi Justin,
First of thanks for your reply, and coming to my requirement, I need to report the list of items which are there in the dynamic select statement what am getting from the DB. The select statement number of columns may vary in my example for different countries the select item columns count is different. For US its '15', for UK it may be 10 ...like so, and some of the column value might be a combination or calculation part of other table columns (The select query contains more than one table in the from clause).
In order to execute the dynamic select statement and return the result i choose to write a function which will parse the cursor for dynamic query and then iterate the values and construct a Type Object and append it to the pipe row.
Am relatively very new for these sort of things, welcome in case of any suggestions to make it simple (Instead of the function what i thought to work with) also a sample narrating the new procedure will be appreciated.
Thanks in Advance,
mallikj2.

Facing problem with a date column in select query

Hi,
I am facing problem with a date column. Below is my query and its fainling with " invalid number format model" .
Query: SELECT *

LAST_UPDATED column is "DATE" data type.

You do not need the TRUNC here in any case.
I don't think so. What if the user wants only data for 22nd May and the table has records with date later than 22nd also? In that case your query willl not work. In order for the Index to work, I think the query can be written like this I think Sean is right though. Use of TRUNC Function is quiet useless based on the condition given here, since the to_date Function used by OP will always point to midnight of the specified date, in this case 22-05-2009 00:00:00.

Edit: I think Sean proved his point... ;)

Hi,
It is similar to bug which is raised in Timesten 11.2.2.2.. BUG 13896607 - COLUMN NAME MISSING FROM A VIEW IN TIMESTEN 11.2.2.2 . If you have MOS access then you can view about this bug. The bug is going to be fix in the future release. The bug basically indicates that we are not displaying the column name properly when select list contains complex expressions. The column itself can be accessed and values are displayed correctly.
Regarding your issue "column TIME_DIFFERENCE not found" , I would suggest you to access the column by position, not by name like below
I believe you are trying to access your column like below
resultset.getString(“TIME_DIFFERENCE”)
Instead of this you can use : -- resultset.getString(2) ( this position should based on the position of the column you are using in the query)
Hope this helps.

Column order in SQL Query (PL/SQL function returning a query)

MDO select query: how to control sort order using parameter

Hi experts, is there a way of controling the sort order of an MDO select query using some parameter?
I was thinking about using some statement like CASE [Param.1] WHEN 'abc' THEN [ORDER_NO]...END in sort section of the query but it is not working.
Of course I colud go for various select queries...but I am wondering if it can be done using only one?
Any ideas?
Thanks for any help

Hi Marco,
Yes this can be achieved dynamically using SortExpr under dynamic link assignment in MDOAction block if you are using a transaction to call it.
Please check below thread:
Re: MDO Query Action Block In MII Transaction
Or else, this [Param.1] thing should work as well provided it doesn't get the logic part in it, just pass the columns names separated by comma. Haven't tried it though, will check it for you.

Select * columns order

Is it possible, that "SELECT *" returns records, where columns are
ordered in a different order, than the order they were
positioned/specified when table was created?
For example, lets assume that table T contains columns c1,c2,..c10.
Can this be possible, that the * (asterisk) shows the columns in a
different orderm the c1 and c10 changed their position for example:
query:
"SELECT * FROM T"
results:
c10, c2, c3, .., c9, c1.
I think you anderstood my question now.
The sql-standard doesn't tell about it nothing, but i have heard that
"selesct *" can produce columns in a random order in some situations.
Notice, that i'm not talking about "ORDER"-operator. I have heard that if one make a table with plenty of columns and adds plenty of indexes and constraints to the columns, then "select *" really will produce mistery column order.
Thank you for answering,
Regards.

FWIW I suspect that block structure is not a factor either.
Consider

View created.

3 rows selected.This returns rows in a consistent (if apparently undocumented) order, which seems to be something like:
* Tables/views in FROM list
* SELECT list
* SELECT list within views in FROM list
* SELECT list of subquery factoring clause
* ALL_TAB_COLUMNS.COLUMN_ID (for tables and views)
* ALL_TYPE_ATTRS.ATTR_NO for attributes of object types
If it did not, it would break many valid PL/SQL constructions as others have mentioned, including %ROWTYPE , UPDATE ... SET ROW, INSERT ... VALUES [record], and INSERT without column list. This type of failure will be familiar to those developing invoker rights packages, since the table found at runtime could have columns in a different order than the one compiled against, which will produce effects such as values appearing in the wrong attributes of %ROWTYPE records.
