ORDER BY timestamp column as a string

Does any one have any tips/tricks for using an ORDER BY clause for a timestamp column that is a string?
I am developing a UNION query that combines data from a table and an audit history table to show current data plus historical data.
I had to convert the timestamp column to a string so the datatypes would match for the UNION query, but now they ORDER BY clause does not work.
For example:
SELECT
location,
'CURRENT' as VALID_DATE
FROM
person
UNION
SELECT
location,
TO_CHAR(audit_date)
FROM
person_audit
ORDER BY 2 DESC

Using the 'yyyy-mm-dd' format works pretty well when ordering by the string. It looks like when ordering by a string Oracle just looks at the characters sequentially.
For example:
2009-1-14
2008-12-31
2007-6-6Looks like you have changed the format slightly?
Consider this
SQL> select TO_CHAR(sysdate,'FMyyyy-mm-dd')
, TO_CHAR(sysdate, 'yyyy-mm-dd') from dual;
TO_CHAR(SY TO_CHAR(SY
2009-5-28 2009-05-28

Problem fetching multiple values in a TIMESTAMP column

Hi all,
I'm having a problem trying to fetch multiple values in a TIMESTAMP column. I can successfully fetch the TIMESTAMP column if I do the following:
OCIDateTime tstmpltz = (OCIDateTime )NULL;
rc = OCIDescriptorAlloc(p_env,(dvoid **)&tstmpltz, OCI_DTYPE_TIMESTAMP,
0, (dvoid **)0);
rc = OCIDefineByPos(p_sql, &p_dfn, p_err, 1, &tstmpltz, sizeof(tstmpltz),
SQLT_TIMESTAMP, 0, 0, 0, OCI_DEFAULT);
This works fine. I can then do what I want with the OCIDateTime variable tstmpltz, like convert it to a text string, etc.
But what I am trying to do is fetch many rows of data that could include a TIMESTAMP column. For character columns this is no problem. I simply allocate a buffer of the correct width and length and then do my OCIDefineByPos to point to the start and the character data gets filled in. Same for numeric columns as well.
I can do this with a TIMESTAMP column if I do the OCIDefineByPos with a column type of SQLT_CHR. But the problem I'm running into when I do things this way is if I fetch a Timestamp value that is before 1950 I believe it is, I get back the wrong century. So for instance 1900 comes back as 2000. I think this is because the default date format when fetching is a 2 digit year. So I've tried to the do following:
long fetchrows = 50;
unsigned char *descpp1;
descpp1 = (unsigned char *)calloc(fetchrows, sizeof (OCIDateTime *));
int i;
for (i = 0; i != fetchrows; i++)
/* Allocate descriptors */
rc = OCIDescriptorAlloc((void *)p_env,(void **)&descpp1[i * sizeof (OCIDateTime *)], OCI_DTYPE_TIMESTAMP,
0,(void **)0);
// Bind the column
rc = OCIDefineByPos(p_sql, &p_dfn, p_err, 1, descpp1, sizeof(descpp1),
SQLT_TIMESTAMP, 0, 0, 0, OCI_DEFAULT);
rc = OCIStmtExecute(p_svc, p_sql, p_err, (ub4) 50, (ub4) 0,
(CONST OCISnapshot *) NULL, (OCISnapshot *) NULL,
OCI_DEFAULT);
And I get an "ORA-01403: no data found" error. I'm missing something here but I can't figure out what it is. Is this proper way to fetch multiple Timestamp columns ?
Thanks,
Nick

Hi Nick,
I think the "trick" here is that when you call OCIDescriptorAlloc normally you would pass a pointer to an OCIDateTime pointer (i.e. OCIDateTime**). However, you're being sneaky here and using unsigned char * with malloc/calloc for the reasons you have already mentioned. So, that changes things a bit because in this scenario the "destination address" where OCI is going to put the address for the OCIDateTime descriptor is in the memory you have dynamically allocated rather than in the target pointer of an OCIDateTime** declaration. So far so good, but the problem, as you've discovered, comes about when you need to get the OCIDateTime* to pass into the OCIDateTimeToText function. In your call you have this:
(OCIDateTime *)descpp1[0 * sizeof (OCIDateTime *)]However, that isn't the address of the descriptor it's a pointer to the address so, depending on your actual calls, etc. you'll either get a memory violation or an invalid OCI handle error. What you can do is get the address from that memory location and stuff it into a proper OCIDateTime* and then it can be used in the OCIDateTimeToText function.
I'm probably doing a terrible job explaining it, but I have cobbled together a sample which does what you want (at least as far as I can tell). Of course, being OCI, there's a fair bit of code, but here's the main parts.
I created a table called "ts_test" that has the following structure and sample data:
SQL> desc ts_test
Name             Null?    Type
TS_ID                     NUMBER
TS_VALUE                  TIMESTAMP(3)
SQL> select * from ts_test order by ts_id;
     TS_ID TS_VALUE
         1 01-JAN-09 08.00.00.123 AM

         4 01-JAN-09 10.00.00.314 PM
4 rows selected.I use the same query as above in the OCI sample code to get the values back out of the table.

Timestamp value[2]: 01-JAN-09 12.34.56.789 PM
Timestamp value[3]: 01-JAN-09 04.46.00.046 PM
Timestamp value[4]: 01-JAN-09 10.00.00.314 PM

How to get data with out having any date/timestamp columns by year wise

hi,
how can i select years wise rows from tables,if that have not any date/timestamp column.

Well Govind it quite depends on what is the data type of that column and the format in which it is stored.
If the data type is varchar2/varchar and all the values are in a uniform format then there is no problem. All you need to use is the to_date function to convert the supplied strings to default date format and then use to_char function to only extract the YY or YYYY or RR or RRRR aspect of the data.
For example: If the column is called 'hire_date' and it's data type is varchar2 and the entries in this column are all in a uniform format, say month,date,year like January,12,1999. What you need to do is convert this string to a default date value using to_date function, like to_date(hire_date,'format_model') In the format model mention the format of the hire_date string. The out put of this function can be fed into to_char to extract the year, like to_char(output_of_to_date,'YYYY')
I hope you got what I meant. Let me know if it was of any use.

Bug: Timestamp columns don't work in automatic row processing

It appears that automatic row processing doesn't work with timestamp columns. Here is the scenario:
- I have a view that contains a timestamp column
- I create an automatic row processing process that reads a row from this view
- I create a hidden item with a source type of "Database Column" and set its source value to the name of the timestamp column.
- The value of the hidden input is empty, i.e. value=""
I found that, as a workaround, if a change the view to convert the timestamp to a string (e.g. SELECT TO_CHAR(LAST_MODIFIED) LAST_MODIFIED rather than SELECT LAST_MODIFIED), it works correctly.
Adding a format mask or doing the conversion in a "post calculation computation" (e.g. TO_CHAR(:P34_LAST_MODIFIED)) doesn't work.

Later on in my exploration I found that some of the text boxes on the Keynote inspector were not accepting text, and so I couldn't even change the transition time for a slide. That prompted a restart of the program and that also seems to have solved the problem where the inspector wasn't accepting input for the columns and gutter. It's working now. So watch out for that. No idea what was at the root of it, which is annoying.

Controlling the sort order for a column?

I have a column which uses strings that I want to sort on. But, I don't want to do simple string sorting. Can I effect the sort order somehow? Maybe enumerate the values and assign integers to them?
For example, I want to use Low, Medium, and High. Or maybe: L-, L, L+, M-, M, M+, H-, H, H+
Any pointers on how to do this?

Todd,
Not knowing what you're trying to sort, it is difficult to make specific suggestions. Basically, two approaches come to mind. 1) start the lines of the column you want to sort with some type of sort code or 2) place that sort code in another column and sort on two columns - possible hiding the one with the codes.
The next problem is designing a code that fits your situation. In the example you gave something like 1L-,2L,3L,...,8H,9H may work because there are only 9 categories. If more than 9, two digit numbers may work but remember to use leading zeros to pad single digit numbers.
The code could also be alpha characters with relevance such as "Auto", "Clot", "Food", "Hous", "Misc", etc. But again, if these alphabetic categories are not in the order you like you may have to precede them with some sequence device to get what you want. Maybe something like "aFood", "bClot", "cHous", etc. would work. Designing a code applicable to a given situation that one can easily remember is not always easy.
Hope this gives to something to think about and if you care to give more details you'll surely get some specific suggestions.

Sorting Timestamp Column in Datagid

HI All,
How can we Sort the TimeStamp Column (Ex: containing
02/05/2007 16:44:03) in a DataGrid. Please help me
Thanks a lot
PSamanth

have a look at the sortCompareFunction property of
DataGridColumn component. This property allow you to define a
callback for sorting a given column. Sort it the way you like in
your function!
Of course, the easiest way would be to part the string as
Date object and use it's comparison methods.

Hi,
Always compare TIMESTAMP columns to other TIMESTAMPs.
To compare a TIMESTAMP column to a value that is being supplied as a string, convert the string to a TIMESTAMP, not the other way around. It's more efficient, and less prone to error.
For example:
SELECT      txn_dt
,     to_char (txn_dt,'dd-mon-yy hh24:mi:ss')
FROM      vcps_misc_ch
WHERE      txn_dt     >= TO_TIMESTAMP ( '18-DEC-2010 14:45:00'
                    , 'DD-MON-YYYY HH24:MI:SS'
;or
SELECT      txn_dt
,     to_char (txn_dt,'dd-mon-yy hh24:mi:ss')
FROM      vcps_misc_ch
WHERE      txn_dt     >= TO_TIMESTAMP ( p_date
                    , 'DD-MON-YYYY HH24:MI:SS'
Do not nest conversion functions (such as "TO_CHAR ( TO_TIMESTAMP ...)"). There's almost always a simpler, more efficient way.
TO_CHAR is appropriate for displaying a date (as in the SELECT clause above). If you're tempted to use TO_CHAR for any other purpose (in a WHERE clause, for example), ask yourself why.

Importing timestamp columns appears to use to_date instead of to_timestamp

I'm trying to import data (using the latest version 1.5.4 with Patch 2 applied) to an Oracle 10g database that contains timestamp columns. The input data has times with fractional (millisecond) values The data was exported using SQL Developer from a Sybase database and the timestamp format in the Excel (xls) file is YYYY-MM-DD HH24:MI:SS.FF3. When I specify this format for the TIMESTAMP columns on the import screens, the importer generates an insert statement like this:
INSERT INTO A (TMS) VALUES (to_date('2008-12-049 12:12:39.967', 'YYYY-MM-DD HH24:MI:SS.FF3'));
This command fails to execute with this error:
Error report:
SQL Error: ORA-01821: date format not recognized
01821. 00000 - "date format not recognized"
*Cause:
*Action:
I found that if to_timestamp is used instead of to_date, there is no issue inserting the row with the correct time precision. The question I have is why isn't SQL Developer using to_timestamp for importing a TIMESTAMP column, and should it?
Any advise woudl be appreciated.
Thanks

In 1.5.4 I see a bug where the "Format" field doesn't show up in the page in the import wizard, preventing the user from entering a mask when the column type is TIMESTAMP. This has been fixed in the code line under development and should be available when 2.1 gets released.
To give you a bit more detail on the confusing DATE/TIMESTAMP behaviour...
SQL Developer misrepresenting date as timestamp and vice versa stems from the behaviour of the Oracle JDBC driver. Following are the details I obtained from the JDBC team when I raised a bug("WRONG VALUE RETURNED FOR GETCOLUMNTYPE FOR DATE COLUMN ") on them:-
oracle.jdbc.mapDateToTimestamp is by default set
to true to indicate reporting DATE column as TIMESTAMP type. To turn off, pass
-Doracle.jdbc.mapDateToTimestamp=false" at the command line.
To effect this option in SQL Developer, you can add an AddVMOption -Doracle.jdbc.mapDateToTimestamp=false
A bit more history on the option:
8i and older Oracle databases did not support SQL TIMESTAMP, however Oracle
DATE contains a time component, which is an extension to the SQL standard. In
order to correctly handle the time component of Oracle DATE the 8i and
earlier drivers mapped Oracle DATE to java.sql.Timestamp. This preserved the
time component.
Oracle database 9.0.1 included support for SQL TIMESTAMP. In the process of
implementing support for SQL TIMESTAMP we changed the 9i JDBC driver to map
Oracle DATE to java.sql.Date. This was an incorrect decision since it
truncates the time component of Oracle DATE. There was also a backwards
compatibility problem trying to write java.sql.Timestamps to 8i databases.
These are separate problems but we "fixed" both under the control of a single
flag, V8Compatible. This flag was introduced in a 9.2 patch set.
By default the flag is false. When it is set to false the driver maps Oracle
DATE to java.sql.Date, losing the time component and it writes
java.sql.Timestamps to the database as SQL TIMESTAMPS. When the flag is set
to true the driver maps Oracle DATE to java.sql.Timestamp and writes
java.sql.Timestamps to the database as Oracle DATEs.
In 11.1 the V8Compatible flag was deprecated because it controlled Database
8i compatibility which is no longer supported. The additional behavior it
controlled, how SQL DATEs are handled, is controlled by a new flag,
mapDateToTimestamp. In 11.1 setting V8Compatible will just set
mapDateToTimestamp. This new flag only controls how SQL DATEs are
represented, nothing more. This flag will be supported for the foreseeable
future.
Finally, the default value for V8Compatible is false in 9i and 10g. This
means that by default the drivers incorrectly map SQL DATEs to java.sql.Date.
In 11.1 the default value of mapDateToTimestamp is true which means that by
default the drivers will correctly map SQL DATEs to java.sql.Timestamp
retaining the time information. Any customer that is currently setting
V8Compatible = true in order to get the DATE to Timestamp mapping will get
that behavior by default in 11.1. Any customer that wants the incorrect but
10g compatible DATE to java.sql.Date mapping can get that by setting
mapDateToTimestamp = false in 11.1.
About the only way to see the difference between mapDateToTimestamp settings
is to call getObject on a DATE column. If mapDateToTimestamp is true, the
default setting, the result will be a java.sql.Timestamp. If
mapDateToTimestamp is false, then getObject on a DATE column will return a
java.sql.Date.

Concatenate multiple columns into one string

Hello,
I am using Oracle 11.2, how can I concatenate the value of multiple columns into one string with one SQL:
create table testTb(classId number(5), classRoom varchar2(32));
insert into testTb value(101, 'room101');
insert into testTb value(101, 'room201');
insert into testTb value(101, 'room301');
insert into testTb value(202, 'room444');
insert into testTb value(202, 'room555');

Hi,
Since you're using Oracle 11.2, you can use the aggregate LISTAGG function:
SELECT       'Class ' || classid
               || ' is in '
             || LISTAGG ( classroom
                     ) WITHIN GROUP (ORDER BY classroom)
               AS txt
FROM       testtb
GROUP BY classid
;The generic name for concatenating all the strings in a group is String Aggregation . This page shows several ways to do it, suitable for different versions of Oracle.

Parse column with csv string into table with one row per item

I have a table (which has less than 100 rows) - ifs_tables that has two columns: localtable and Fields. Localtable is a table name and Fields contains a subset of columns from that table. Fields is a comma delimited list: 'Fname,Lname'. It looks like
this:
localtable         fields
========= =============
customertable   fname,lname
accounttable     type,accountnumber
Want to end up with a new table that has one row per column. It should look like this:
TableName             ColumnName
============ ==========
CustomerTable        Fname
CustomerTable        Lname
AccountTable          Type
AccountTable          AccountNumber
Tried this code but have two issues (1) My query using the Splitfields functions gets "Subquery returned more than 1 value" (2) some of my Fields has hundreds of collumns in the commas delimited list. It will returns "Msg 530, Level 16, State
1, Line 8. The statement terminated. The maximum recursion 100 has been exhausted before statement completion.maxrecursion greater than 100." Tried adding OPTION (maxrecursion 0) in the Split function on the SELECT statment that calls the CTE, but
the syntax is not correct.
Can someone help me to get this sorted out? Thanks

Max value for a TIMESTAMP column?

What is the max value for a TIMESTAMP column?
I'm using the ODP.NET provider 9.2.0.4. When i put C#'s DateTime.MaxValue (i.e. 12/31/9999 23:59:59,999) into a TIMESTAMP column, everything is ok. Retrieving this value (e.g. via SQL*Plus Worksheet) returns ora-01877 (string too long for internal buffer).
Any ideas?
Regards,
Daniel

Maybe you hit Bug 1782816 Select of TIMESTAMP gives ORA-1877 on some platforms

Get millisecond values from timestamp column in v$logmnr_contents

Hello
How do we get millisecond values from timestamp column in v$logmnr_contents.
I tried with following query.
select scn,To_Char(timestamp,'DD-MON-YYYY HH24:MI:SS:FF') from v$logmnr_contents WHERE OPERATION NOT IN('START') and username ='SCOTT' and sql_redo is not null and (seg_owner is null or seg_owner not in('SYS'));
it says ORA-01821: date format not recognized. I want to find the relation of scn with timestamp. In forums i found, scn is derived from timestamp value. I dont know its correct or not.
if i query with out FF in time format i get like
scn timestamp
808743 27-NOV-2007 00:12:53
808743 27-NOV-2007 00:12:53
808743 27-NOV-2007 00:12:53
808744 27-NOV-2007 00:12:53
808744 27-NOV-2007 00:12:53
808744 27-NOV-2007 00:12:53
if scn is derived from timestamp with milliseconds, each scn should be different right?More help please

May be there's an easy way solving your problem, I did it like that:
CREATE TABLE quota_test (test VARCHAR2(50))
INSERT INTO quota_test
VALUES ('update "SCOTT"."NEWTAB1" set a="34" and b="45"')
SELECT test normal, REPLACE(SUBSTR(test,INSTR(test,'"',1),INSTR(test,'.',1)+2),'"','') changed
FROM quota_test
Result is :
NORMAL
update "SCOTT"."NEWTAB1" set a="34" and b="45"
CHANGED
SCOTT.NEWTAB1
If you didn't understand, I can explain what I wrote

How to create a default value of timestamp column?

I am trying to create a table with a default value on a timestamp column, can it be done?
CREATE TABLE myTbl
FutureDateTime date default TIMESTAMP WITH TIME ZONE '2999-12-31 23:23:59.000'
)

)Yes, but you don't have a timestamp column, you have a date column.
CREATE TABLE myTbl
FutureDateTime date default to_date('2999-12-31 23:23:59', 'yyyy-mm-dd hh24:mi:ss')
4 );
Table created.
Elapsed: 00:00:00.09
ME_XE?And just in case you weren't aware, storing "end of time" information like this will be rough on your queries (it skewes the cost based optimizers estimates for cardinalities and could wildly throw off the estimates for your queries, resulting in bad plans). You're better off to store NULL values, NULL denoting not known values.
Just an FYI :)

How i pass table column value to string variable or return to java applete

Hi Master,
How do I pass a table column value into string variable. See my code below:
import java.sql.*;
public class Waheed {
public Waheed() {
public static void main (String args [])
String s = "9 23 45.4 56.7";
System.out.println ("going for connection");
// DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn =
DriverManager.getConnection("jdbc:oracle:thin:@fahim:1521:aamir","muhammad","mfa786");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select accid from accbal");
System.out.println ("going for connection");
while (rset.next())
s= rset.getString("accid"); this line give me error
System.out.println (rset.getString("accid"));
System.out.println (s);
catch(Exception e){
e.printStackTrace();
This line give me an error:
s= rset.getString("accid");
s is string variable
Plese give me an idea how I can pass accid in s variable.
Thanks.
Aamir
