SQL & PL/SQL :: Row To Column / Column Data Can Be Varied From 1 To Any Number Of Words
Mar 21, 2013
I have a table where i have description column which free text column, the data in description column is seperated and i want to corvert 1 row data in multiple rows dependeing on the number of words.
eg
id description
78664 Pumps Alarm from CAMS RTU154
In the above example this column has 5 word so i want data in 5 rows like below
78664 Pumps
78664 Alarm
78664 from
78664 CAMS
78664 RTU154
This column data can be varied from 1 to any number of words.
I am having issue with Oracle reserved words, one of the application is using table which has NUMBER as column. I am not able to query that table matching database with NUMBER column.
HERE
select a.* from DOC a , FOLDER B where a.NUMBER= B.INCIDENT_ID and b.open = 'Closed'; I tried double quotes (“”) and sigle quotes too, none of them worked.
I have a table with the following column and data is like this.
SQL>CREATE TABLE test ( column1 varchar2(50)); SQL>INSERT INTO test VALUES('ABC XYZ'); SQL>INSERT INTO test VALUES('MNO PQR'); SQL>INSERT INTO test VALUES('ABCD ABC'); SQL>INSERT INTO test VALUES('PQR MNOP');
My requirment is to find the top 20 most occurred words in the perticular text column accross the full table. i WILL have desc column which is plain text where user wites the essay. i have below 2 data example where i have 2 find which word occur most of the time. i have more than 1 million data where i have to perfor this calculation

After speaking to the Hainault DDM and the Hainault DMT it has been established that 70000031E105 on entering into platform by one cars lenght applied emergency brakes to stop the train due to a person under his train. Train stopped with two cars still outside the platform. I received a call from Line Controllor at 0823 hrs that a person has jumped in front of train 105 at Greenford. I informed Ian Williamson Train Operations Manager. We traveled on a special taxi with a spare Train Operator at 0839hrs and reached Greenford Station at 0859hrs.

'E105 on entering into platform by one cars lenght applied emergency brakes to stop the train due to a person under his train. Train stopped with two cars still outside the platform. I received a call from Line Controllor at 0823 hrs that a person has jumped in front of train 105 at Greenford. I informed Ian Williamson Train Operations Manager. We traveled on a special taxi with a spare Train Operator at 0839hrs and reached Greenford Station at 0859hrs. Emergency Services ( Police, London Ambulance, London Fire Brigade and ERU) were already on site. When spoken to Line Controlllor stated he received a normal radio call from E105 to inform him that he has got a person under his train. At 0826 Line Controllor had traction current switched off between Northolt and Greenford. Train service was suspended from North Acton to West Ruislip in both directions (east and west).
I could not speak to the Train Operator as Police was in the process of interviewing him and he was too traumatised to speak. Trauma Support was arranged from Loughton as we had no one available at West Ruislip and White City. Trauma Support spoke to T/OP over the telephone and Train Operator decided to travel in a special taxi which was booked for him on his own, although a Station Staff was was arranged to travel with him. During the process a spare T/OP stayed with this T/OP. When spoken to Mr. Clack Operations Security Manager stated he was traveling on this train from West Ruislip and made a telephone call to Network Operations Centre at 0826hrs to inform them of the situation. Mr. Clack travelled to the leading cab and confirmed that although the T/OP was badly shaken but he carried out his duties in a professinal manner by placing Short Circuiting Devise in front of the train and second SCD was placed on the rear of the track by Station Supervisor after traction current was discharged. Passengers were detrained by operation butterfly cock. Les Blaxwall Operations Standards Manager was also travelling on this train and offered his to T/OP. Mr. Blaxwall assisted in the wrong direction move and stayed till the end of the operation to assist. Wrong Direction move was carried out by T/OP Martin to assist emergency services for the track search. The deceased was an elderly of Asian origin approximately of 65yrs of age wearing white shirt, beige trauser and white trainers. When CCTV was viewed he was seen pacing up and down on the east bound platform near the waiting room. On approach of T105 he jumped in front of the train at 0824hrs and train stopped with two cars outside the station. The body was removed from platform at 0940hrs by ERU and taken in a body bag to the secure room at Greenford Station. Track was accessed by BTP to carry out track search for any trace of identification at 0932hrs and gave all clear at 0942hrs.
TOM Williamson assisted in closing the train doors by operating the butterfly cock to close position. Traction Current was switched on at 0948hrs and T105 was worked empty to North Acton and reversed to Ruislip Depot. All clear was given at 0951hrs and after station search, Greenford Station was re opened at 0955hrs. E142 was the first train to run in service on the east bound. Body was removed at 1013hrs from Greenford Station and taken to Uxbridge by the police. Trauma Support was offered to Station supervisor by his DSM, but he declined the offer. Service Manager and Line Controllor were kept informed by myself.'); Insert into tbl_incd ( INCIDENT_NO,SD_DESC) Values

I have one hirarchical query which return the parent to child hirarch level data. it has 11 level child data. i want to create column based on number of child in hirarchy. though i know it is 11 but it can change also.Is there any way i can create the column dynamically
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.
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:
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
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]........
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"
Now i have a problem which i am facing for the first time. The problem is:
I have created a table test1 with two column of number data type and the column witdth is 25. Then enter the data but when i select the recrod it does not display the column data as it was entered. SQL> create table test1 2 ( 3 startno number(25), 4 endno number(25) 5 );
my column type is NUMBER(10,0) ,it accept the input value from text field I using TO_NUMBER(?) to insert value into table, is the a way to handle if the input is 'aaaaaaaaaa' not digit?
In chapter 17 of the 'Oracle Database 10g, The Complete Reference' it says "You can increase or decrease the number of decimal places in a NUMBER column at any time". When trying to modify a column from NUMBER(38) to NUMBER(38,3) I get the ORA-01440 error. Is there a way around this when you have the maximum number of digits (precision = 38).
I have a column defined as Number( 8 ) which is supposed to have date values. I would like to check if all the rows in that table have valid dates. We could use to_date(coulmn_name, 'YYYYMMDD') and catch the rownums for error conditions using pl/sql. I would like to know if we could just do it using sql only and return the row numbers for those that are invalid dates?
I want update col1 whis is null to max(col1) ++ in a row, order by cr_date like 1,1,20110102 2,2,20110101 3,null,20110105 => 3,5,20110105 because this row is after 20110103 4,3,20110104 5,null,20110103 => 5,4,20110103 because this row is before 20110105
update test_table set col1 = (select max(col1) from test_table) + rownum where col1 is null;

The M column is used to count the total number of occurrences of a SLOT. Now, as for the N field, this is used to count the occurrence of the SLOT. In my example for the SLOT TRALTEST43S1, it has three occurrences so M will be 3. Why 3, is because of the WIPDATAVALUE. The WIPDATAVALUE of TRALTEST43S1 is 1-2 and 3. 1-2 WIPDATAVALUE signifies two occurrences (one to two) and 3 signifies only one occurrence. As for N, it should just count the number of occurrence. To further explain, see below:
WIPDATAVALUE SLOT N M 1-2 TRALTEST43S1 1 3 -> First occurrence in the total of 3 1-2 TRALTEST43S1 2 3 -> Second occurrence in the total of 3 3 TRALTEST43S1 3 3 -> Third occurrence in the total of 3 4-6 TRALTEST43S2 1 4 -> First occurrence in the total of 4 4-6 TRALTEST43S2 2 4 -> Second occurrence in the total of 4 4-6 TRALTEST43S2 3 4 -> Third occurrence in the total of 4 7 TRALTEST43S12 4 4 -> Fourth occurrence in the total of 4
This is the query that I have so far:
SELECT DISTINCT WIPDATAVALUE, SLOT , LEVEL AS n , m FROM ( SELECT WIPDATAVALUE , SLOT , (dulo - una) + 1 AS m [code]....
I think that my current query is basing its M and N results on WIPDATAVALUE and not the SLOT that is why I get the wrong output. I have also tried to use the WITH Statement and it works well but unfortunately, our system cant accept subquery factoring.
I want to decrease the size of testid column of number datatype in my "test" named table from size 20 to 15 and the data of maximum size is of 10 digits. but oracle throws an error "ORA-01440: column to be modified must be empty to decrease precision or scale". i cant understand why it is happening?
what is the reason behind it even though new size is maximum than the maximum size of existing data. but when i decrease the size of "varchar2" then oracle does not through any error.
here on your forum but has been following several threads ever since.So anyway here is the thing, I have a query that should return count the number of rows depending on the value of SLOT. Something like this:
As you can see above, on the SLOT TRALTEST43S1, there are three occurrences so M (Total number of occurrences) should be three and that column N should count it. Same goes with the SLOT TRALTEST43S2. This is the query that I have so far:
SELECT DISTINCT WIPDATAVALUE, SLOT , LEVEL AS n , m FROM ( [code]...
I think that my current query is basing its M and N results on WIPDATAVALUE and not the SLOT that is why I get the wrong output. I have also tried to use the WITH Statement and it works well but unfortunately, our system cant accept subquery factoring.
I have table customer which contains a column CUSTOMER_FIRST_NAME
CUSTOMER_FIRST_NAME VARCHAR2(50)
What will be sql statement to add a constraint on the CUSTOMER_FIRST_NAME column of the CUSTOMERS table so that the value inserted in the column does not have numbers ?
I need a generic query to generate total # of records for each table in a schema, total # of records that are not null for each column in the table, and total # of records that are null for each of those columns in those tables.
ex:
the output should look like this.
owner schema table_name total# recs in the table, column_name, ------ ------ ---------- ------------------------- -----------
# of records not null # of records null ---------------------- --------------------
