SQL & PL/SQL :: Add A New Counter Column

Jul 25, 2011

I need to enhance the design of one of the tables by adding a primary key to it. i need to know how to fill this new column with sequenced serial before I change it to Primary key.

CREATE TABLE AFESD.REQUEST_TO_FINANCE
(
REFERENCE_NUMBER CHAR(10 BYTE) NOT NULL,
ISSUE_DATE DATE NOT NULL,
RECEIPT_DATE DATE NOT NULL,
DESCRIPTION VARCHAR2(250 BYTE),
FK_COUNTRYCODE NUMBER(3) NOT NULL
);

ALTER TABLE N_REQUEST_TO_FINANCE ADD REQUEST_SERIAL NUMBER(6);

Now I need to add values to REQUEST_SERIAL but can figure how to do that in SQL. I even tried to use your previous tip and use row_number() but it can only return a full set of values not a single one.

SQL & PL/SQL :: Using Sequence To Insert In Child Table Group By A Counter Column

Oct 1, 2011

I found nothing in SQL (all in PL/SQL).I have a table:

create table Parent (pk_id number primary key); --which is filled using sequence seq_Parent.

And I have a child table:

create table Child (rRef number, fk_parent number primary key (rRef, fk_parent);

that I need to insert into Child using seq_parent but I want to insert the same sequence for each group of rRef. I dont know how to do that using SQL not PL/SQL.

SQL & PL/SQL :: Associative Arrays Counter

Mar 30, 2012

oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE 11.1.0.6.0 Production"

declare
l_sql_stmt VARCHAR2(1000);
l_year NUMBER(4);
l_event_id NUMBER(2);

[Code]....

Sql gives result like

YEAR EVENT_ID
1995 111
1996 111
1997 111
1998 111
1996 111
1995 111
1995 111

SO I am trying to do like

l_my_arr(1995):= 1 ;
l_my_arr(1996):= 1 ;
l_my_arr(1997):= 1 ;
l_my_arr(1998):= 1 ;
l_my_arr(1996):= 2 ;
l_my_arr(1995):= 2 ;
l_my_arr(1995):= 3 ;

But if I put l_my_arr(l_year) := 0, immediately after FETCH, then the counter is always 1, and I cannot put it before because l_year has to be FETCHED.

SQL & PL/SQL :: Resetting Row Counter Based On Variable

Apr 17, 2002

I'm wondering how I can use a counter to number records in a table I'm inserting into. I need the counter to reset based on changing data in my table. For example, I have the following

seq_number name_type
1 Short Name
1 Short Name
1 Short Name
2 Short Name
2 Short Name

I'd like my results to be the following:
seq_number name_type
1 Short Name - 1
1 Short Name - 2
1 Short Name - 3
2 Short Name - 1
2 Short Name - 2

I'd like my counter to increment so that I can add a sequence number to the end of my name type, but when my seq_number field changes I'd like to reset and restart my counter.

Forms :: Way To Get Default Record Counter

Jan 25, 2010

I been looking high and low for a way to get the default record counter, at the bottom of the window, to provide how many records have been returned by any query.You know the record 1/? or record 1/10 at the bottom.

I don't want to do an:
execute_query;
last_record;
first_record;

Nor do I want to set the "query All Records" property of the data block to "Yes". Both result in the form opening up way too slow. I've a table with a total of 29500+ rows.

SQL & PL/SQL :: Create Counter For The Number Of Inserts Run In A Block

Feb 18, 2010

I have a plsql Proc, which accepts a few parameters and inevitably loops through a cursor and runs a bunch of insert statements. With quite a few IF conditions.

Each insert statement has a value which i want to increment by (+1) every time an insert statement is executed in the same loop.. This is for a student housing database and this is for their room preferences so 1 is the first, 2 is there second preference e.t.c.

Please take a look at the code below: in the Insert values() I have put a? Where I want the number to increment from.

There are a lot more inserts which I haven't put below. I hope I have made myself clear as this has been quite difficult to explain. So for example if the 2nd two inserts are run, then I was the first one to insert with a 1 and the second with a 2.

BEGIN
FOR rec IN c1
LOOP
IF c1%FOUND THEN
INSERT INTO table (PK_A, fk_rms_id, application_type, application_person_type) VALUES (NULL, rec.pk_rms_id, app_type, app_person_type) RETURNING PK_APPLICATION_NO INTO x;

XML DB :: Increment Counter In Loop Based On Condition?

Jan 24, 2013

I want to increment a counter in a loop based on a condition.

Here is how my xml looks like

<result>
<resultset id=1>
<value>

[Code]....

I need to look at each and every resultset and check if the value is >400 and if it is then display some text. Something like this

<outputvalue>
Yes, there is a value greater than 400
</outputvalue>

In my XSL, I declared a variable called count with value 0. I created a for-loop which goes through these results. Then inside the loop there is a condition to cehck if the value is > 400. If the value is >400, then the counter is incremented.

````````````````````
<outputvalue>
<xsl:variable name="Count" select="0"></xsl:variable>
<xsl:for-each select="/results/resultset">

[Code]....

There is a problem with the above code is that result is like this

<outputvalue>
*1*
Yes there is a resultset with greater than 400
</outputvalue>

Is there a way I can just remove the character 1 from the output? Or is there a better way to increment?

Application Express :: Hyperlink Column With Link Parameters As Region Column Values

Apr 10, 2013

On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.

I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.

So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:

a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?

The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.

I receive the error,

REP-1241 Circular column dependency originating with column 'cenvat_opening'

I have the following return statement for a column total_credit;

function total_creditFormula return Number is
begin
Return (return nvl(:cf_cenvat_closing ,0) - nvl(:cf_duty_on_goods_ed,0);

Now i am using this total_creditFormula for the error formula column 'cenvat_opening'

function cenvat_openingFormula return Number is
f_num_opn number(14,2);
begin
SELECT NVL(Amount,0) INTO F_NUM_OPN

[code]...

here the formula column 'total_credit' has the following return statements;

RETURN Nvl(:cenvat_opening,0) + Nvl(:cenvat_credit_manu,0)

so how can i use this formula column? is there any other option to return the value in the same column.

Pivot Query In Oracle To Get Years From Column And Make Separate Column For Each

Jul 22, 2009

I'm trying to do a pivot query in oracle to get the years from a column and make a separate column for each. I found an example of the code to use on the internet and i changed it for my own tables but i'm getting errors. Namely a "FROM keyword not where expected" error at the beginning of the 'avg(...' statements.

I have copied the code used in

select stud_id,
avg(case when year=2006 then ((present/poss)*100) else null end) 2006,

Reports & Discoverer :: Value In Table Column Based On Some Existing Column Value Automatically Without User Intervention

May 15, 2011

i have two questions.

(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'

(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.

Reports & Discoverer :: How To Make Name Of Column Appear As Many Times As Column On Page

Nov 21, 2010

This is what i want to do:

I have a basic report looking like this:

<Column name>
value 1
value 2
value 3
.
.
.
value n

Since the column is small it can fit in a page more then one time. I know how to make it print more then once: i switch the repeating frame to print down and across and i modify the frame that contains it so the horizontal elasticity is variable.

After these changes my report looks like this:
<Column name>
value 1-----------------------value n+1-----------------------value m+1
value 2-----------------------value n+2-----------------------value m+2
value 3-----------------------value n+3-----------------------...
.------------------------------- .
.------------------------------- .
.------------------------------- .
value n-----------------------value m

What i want is my report to look like this:

<Column name>-------<Column name>------------<Column name>
value 1-----------------------value n+1-----------------------value m+1
value 2-----------------------value n+2-----------------------value m+2
value 3-----------------------value n+3-----------------------...
.------------------------------- .

Application Express :: Column Link Where Column Number Changes With Query

Feb 11, 2013

We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report

<code>select * from(
select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site,
case when count(*) < 31 then '*' else
round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct
from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b
where Overall_Satisfaction is not null and year_dt = 2012

[Code]....

The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.

Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)

ie
Overall Satisfaction JAN FEB MAR APR MAY ...
Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
etc.

So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.

PL/SQL :: Bitmap Index On Number Column X Char Column?

Jul 23, 2013

is there some performance/access difference between a bitmap index on a number column and char(1) column? Both columns are not null with a default value.My application has a querie like this:  

select ass.column20,  ass.column30from table_a pucinner join table_b asson ass.column1 = puc.column1where pc.column_char = 'S'and ass.column_char02 = 'P'    

If I create a bitmap index on column "column_char", the access plan is not changed. But changing the column datatype to number(1) and obviously the values, the index is accessed and the cost decreases.This table has 4.000.000 rows. Oracle 11.2.0.2SO

SQL & PL/SQL :: Converting Number Column To Date Column

Dec 25, 2012

I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD

CREATE TABLE T1.monthly
(
SEQ_NUM NUMBER(10) NOT NULL,
DAY_DK NUMBER(10) NOT NULL
)
TABLESPACE USERS
PCTUSED 0
PCTFREE 10
[code]........

some sample data

SEQ_NUM DAY_DK
---------- ----------
990 20121225
991 20121225
992 20121225
993 20121225
994 20121225
995 20121225
996 20121225
997 20121225
998 20121225
999 20121225

When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.

desc t1.mth; ### my temorary table
Name Null? Type
----------------------------------------- -------- ----------------------------
SEQ_NUM NUMBER(10)
DAY_DK NUMBER(10)

Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.

alter table n546830.mth modify (DAY_DK date);

Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:

alter table t1.monthly exchange partition DEC_2012
with table t1.mth without validation;
alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation
*
ERROR at line 1:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION

Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"
