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 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 ?
Is there a seeded function by which I can check all the rows which stored dates in varchar column.
I have a table say test (test_data varchar2(100));
Now I will insert all types of records into the table varchar,number dates and then i will write q query to etch all those records only which has dates only
INSERT INTO test(1); INSERT INTO test('ABC'); INSERT INTO test(SYSDATE); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY')); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY HH24:MI:SS')); INSERT INTO test('15/01/2012'); ... commit;
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"
I have a text column having date data. In the format of YYYYMMDD.Some of the records might have invalid date data as well. Is there any function which checks whether it's value is a right DATE? Something like
I have been tasked to validate the date format of some attributes in a table. So, to verify the data we will be getting the filed and the format to check against.
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
My requirment is to find out the period names and transactions which are in valid date formats and are less than sysdate and the non date formats are adjustments made by different users for their transactions

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?
how to run a spell check on a column (contains desriptions) of a table and find out if any spelling mistakes are there in the text of that column. I want to run this in pl/sql.
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
create table teststr (indname varchar2(20), counter1 number,counter2 number,counter3 number,counter4 number); insert into teststr values('a',10,20,30,30); insert into teststr values('b',10,20,5,3); insert into teststr values('c',2,4,5,2); insert into teststr values('d',1,2,3,4); insert into teststr values('e',4,5,4,4);
Now i need the output if any of the column values are same.
output should be
select indname from teststr where counter1=counter2 or counter1=counter3 or counter1=counter4 or counter2=counter3 or counter2=counter4 or counter3=counter4

Is ther any other way to write the query instead of the numerous or conditions if i want to compare the column values in a table.
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.
In the below code, do I need the 'NOT NULL' after the 'state char(2)'? I am guessing that I do not need it since I have the CHECK constraint on the column.
CREATE TABLE employee( id PRIMARY KEY, first varchar(20) NOT NULL, middle varchar(20), [code]....
I'm going to do some testing, and for that I require to retrieve some data based on a single column e.g test_data_col, which -
1. Has 3 or more count(test_data_col) for a given set of group by columns e.g grp_col1, grp_col2, grp_col3 2. Within the set of rows retrieved, that particular column holds some duplicate values. I don't need the duplicates displayed, just know if duplicates exist or not.
This might explain what I'm trying to do -
grp_col1, grp_col2, grp_col3, test_data_col
1, A, xyz, HELLO 1, A, xyz, HELLO 1, A, xyz, BYE 1, A, xyz, GOODBYE
2, C, pqr, WELCOME 2, C, pqr, GOOD MORNING 2, C, pqr, BAD MORNING
So for condition 1, I do something like this -
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3 FROM test_tab GROUP BY grp_col_1, grp_col2, grp_col3 HAVING COUNT(test_data_col) >= 3;
In this same query, I want to do something that will tell me if the aggregate COUNT(test_data_col) has any duplicate values within it. Again, displaying the duplicates is not important here.
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3, /*some logic*/ dup_val FROM test_tab GROUP BY grp_col_1, grp_col2, grp_col3 HAVING COUNT(test_data_col) >= 3;With the proper coding to replace /*some logic*/, I get following values -
cnt, grp_col_1, grp_col2, grp_col3, dup_val
4, 1, A, xyz, Y 3, 2, C, pqr, N
I just gave dup_val column to explain what I'm trying to achieve.. any other way to know the existence of duplicates in the count aggregate will be fine.My Oracle version is Oracle Database 11g Enterprise Edition Release 11.1.0.7.0
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.
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 want to produce a function who return XmlType element if she checks that a parameter (that i passed to here is contained in a row in a defined table)
for example
create table sec_form( form_code VARCHAR2(8) , sec_code VARCHAR2(5) ) ; insert into sec_form values ('CSA','section1'); insert into sec_form values ('CSA','section2'); insert into sec_form values ('CSA','section3');
then i got my function
create or replace function checkIfSectionEnabled (elem XmlType,name_section varchar2) return XmlType is v XmlType; CURSOR myCursor IS select * from sec_form where form_code = 'CSA'; begin open myCursor; loop
[code]....
now i'm gonna call the function (elem XmlType,name_section varchar2) and pass here "section1" for example ; and she must return me my xmltype element if she find "section1" finds section1 present;
when i try t compile i got:
Error(18,13): PL/SQL: Statement ignored Error(18,26): PLS-00225: subprogram or cursor 'MYCURSOR' reference is out of scope
CREATE TABLE TEST ( X NUMBER(8), SNUM NUMBER ) SET DEFINE OFF; Insert into TEST (X, SNUM) Values (20100409, 1); Insert into TEST (X, SNUM) Values (20100317, 1);
[Code]...
For some reason, column x is a number data type, but the data is actually date.
My aim:
1. select the maximum of the dates stored in column x (in numeric data)..for a given snum.
2. check if it is within 3 days range and return 1 or 0
My program
CREATE OR REPLACE FUNCTION f_chk (in_num number) RETURN NUMBER IS v_chk NUMBER; v_max_dat number; BEGIN SELECT COUNT (*) INTO v_chk
[Code]....
I have following assumptions, correct me if I am wrong:
SELECT max(x) INTO v_max_dat FROM test WHERE snum = in_num;
1. The above will actually give me the maximum date for a given snum (correct result), since the data is stored in yyyymmdd format, it does actually picks up the maximum date (stored in number format) for a given snum ... or should i use to_date to convert it to date and declare v_max_dat as date ?
I want to change a table datatype from date to number where already existing data should get convert.any possibility of doing where i tried like this but no get changing. Even as Julian format is working a bit i want the data to come as GMT format
Scenarios where i tried are like this.
ALTER TABLE Contacts ADD ALERT_DATE1 NUMBER(20,0) / UPDATE Contacts SET ALERT_DATE1 = TO_NUMBER(ALERT_DATE) / ALTER TABLE Contacts DROP COLUMN ALERT_DATE / ALTER TABLE Contacts RENAME COLUMN ALERT_DATE1 TO ALERT_DATE /
but second statement failing.
Julian fomat like
SELECT sysdate, TO_CHAR(sysdate, 'J'), TO_DATE(TO_CHAR(sysdate, 'J'),'J') FROM dual;
