I have table called INFO and the column called CREATED_DATE . Now the datatype of CREATED_DATE is of varchar2 . Now If I need to query the table through select statement where I need to order the result based on CREATED_DATE , how can i achieve this ?
View 1 RepliesI have problem to convert simply varchar to date data type.
For example: 2012-05-28 22:36:08 and I would like to get format 28.5.2012 22:36:08
However I try to do it I get always some errors.
select '2012-05-28 22:36:08',
to_date( '2012-05-28 22:36:08', 'dd.mm.yyyy HH24:MI:SS') ,
to_char('2012-05-28 22:36:08', 'dd.mm.yyyy HH24:MI:SS')
from dual
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');

Is there some functions to convert the long type field data to varchar2 type?

when used this code but it's not working
select sum(to_number(cheq))
from table_name but the code not working
second column "date_due"
i want search between to date i used this code but also not working

i have a varchar2 column containing string values that can be converted to date i.e. ('31-JUL-11') and that column also contains text strings in it. i.e. ('Some string data...')
records whose column value can be converted to date are extractable via where clause (i.e. those rows are associated with some fix number / flag)
now when i try to use to_date function i get the error that
" ORA-01858 a non-numeric character was found where a numeric was expected "
in sql i have added a where clause to only pick rows with flag, but even then it gives the error.
using a subquery in the from clause eliminates the error, but when i create it in a view it again gives the same error.

I have a query like below:
select col1, col2, col3, col4
from tab1, tab2, tab3
where conditions
union
[Code]...
Now, the col4 is a date column and I have to order by the entire result sets on it. I know I can do it by (order by col4) or by (order by 4) at the end of the entire query.
But the problem is that, the output is coming in dd-Mon-yyyy (i.e 31-Nov-2012).
I want every output in dd/mm/yyyy format so I need to use to_char function.
But in that case, I cant use the order by clause, because in that case it is getting arranged by character i.e by 1,2,3,4,5 like this.

This is my query
select to_char(exp_Date,'Mon-YYYY') dt, count(*) from exp_main
where exp_type like 'Income%Photo%'
group by to_char(exp_Date,'Mon-YYYY')
order by exp_date
When I run this I get :not a GROUP BY expression
If I remove the order by, it works fine.
Is there a way to order by since the output of the query is character-sorted.
I did search online most have suggested to use order by column_name. But does not work for me.

How do I make a Date field filter in a descending order when the form is opened? Also, can I add a 'when-mouse-doubleclick' trigger to sort the date field in ascending and descending order (this is a client requirement)?
i am fairly new in the oracle arena, but what would cause a statement such as

In the database, NLS_DATE_FORMAT = DD-MON-RR.I have a date field called LOAD_DATE in one of the tables. I want to store the value as '25-OCT-11 01:16:25 PM' in LOAD_DATE field. Is there a way to do it without changing the NLS parameter (ALTER SESSION...) ?
I am working with Oracle 8i and I have a problem while applying the below query:

I checked the DDL of both tables and the only difference is that the TBL_XX_PROGRAM have the ENTRYDATE field defined as not null and the ENTRYDATE on the TBL_BANDWIDTH_READS does not have the same constraint, could it affect?

First, I'm aware that the equals (=) operator is a "comparison operator compares two values for equality." In other words, in an SQL statement, it won't return true unless both sides of the equation are equal. For example:
SELECT * FROM Store WHERE Quantity = 200; The LIKE operator "implements a pattern match comparison" that attempts to match "a string value against a pattern string containing wild-card characters."
For example:
SELECT * FROM Employees WHERE Name LIKE 'Chris%';
Here,I query about date type data on ORACLE database, I found the following, when I write select statment in this way:
SELECT ACCOUNT.ACCOUNT_ID, ACCOUNT.LAST_TRANSACTION_DATE FROM ACCOUNT WHERE ACCOUNT.LAST_TRANSACTION_DATE LIKE '30-JUL-07';
I get all rows I'm looking for. but when I use the sign equal =
instead :SELECT ACCOUNT.ACCOUNT_ID, ACCOUNT.LAST_TRANSACTION_DATE FROM ACCOUNT WHERE ACCOUNT.LAST_TRANSACTION_DATE = '30-JUL-07';
I get nothing even though nothing is different except the equal sign.
I have a table with two columns called startsem and gradsem they are both CHAR(3). Within those colums are rows that are listed as SemesterYear. For example, F09 is Fall 2009, S09 Spring 2009, and M09 is Summer 2009. I would like to create a constraint that says GradSem must be greater than StartSem b/c no one can travel back in time to graduate. However, as you know you can compare S09 > F09 because it will treat it as a string. I thought I could use a substring and compare the last two digits as a year and that would work but how do I compare the semesters as a time frame? Because in my schema F > S because Spring 2011 comes before Fall 2011 but in reality F < S because to Oracle it is a string and the ASCII value of F is less than S. I cannot chage the coding of the database so editing the rows so they are more date friendly is not an option.
So how can I modify this database to acruately compare StartSem and GradSem.
