cast( from_tz( cast( SYSDATE as timestamp ), 'US/Pacific') at time zone 'UTC' as date)


Date today I tested, its gives me the correct value, but for the test date when day light economy performed as June 25, 2013.

I wanted to define after date for my session and do some tests.

could if it you please let me know sql for the session with over date formatting.

Thanks 4 your help!

  • database stress test - datagenerator problem with import data from oracle

    Hi all

    Today, I'm doing a stress test on my new server. Someone from this forum told me that there is a nice software for it:

  • Problems with the date in the procedure on Oracle 11 g

    Hi gurus,

    I have some problems with the date under Oracle 11 g format.

    Let me explain the situation:

    When I start such a request
    Select to_number (to_char (to_date('01.04.2009','dd.mm.yyyy'), 'yyyy'))
    of sys.dual

    I had as a result 2009 under the number.

    When I do the same thing in a procedure of a package like this

    my_year: = to_number (to_char (to_date('01.04.2009','dd.mm.yyyy'), 'yyyy'));

    the my_year variable contains the value 9 instead of 2009.

    Can someone explain to me what goes wrong?

    I just tested with the evolution of the variable nls_date_format of environment for the session and the database is complete without success.

    Kind regards

    Yes, it has everything to do with your environment settings.

  • Importing bulk data into Oracle - with restrictions

    Hello

    I am trying to insert data from a stream (inside the ETL tool) of bulk in Oracle via a stored procedure, but under many restrictions. Hope you can help.

    Oracle 10 g database is.

    There is up to 1 000 000 records of about 100 bytes each, through delivery, to about 200 000 000 per day.

    Target table:

    CREATE TABLE TBL_STG
    ("KEY", NUMBER (13.0),)
    "ATT_1" NUMBER (1.0).
    NUMBER (14.0) "TIMESTAMP."
    "ATT_2" NUMBER (14.0).
    "ATT_3" NUMBER (14.0).
    "ATT_4" NUMBER (2.0).
    "ATT_5" NUMBER (1.0)
    )

    I can easily convert the stream of input documents in a collection (list separated by commas, for example) with the ETL tool that I use. I then call the stored procedure with the collection of records (delimiter: comma) as one of the parameters.

    The problem is that I am using the ETL tool in slightly modified middle (emulation of continuous treatment) which greatly limits my possibilities to load data into Oracle.

    Basically, I can't use utilities (for example, SQL * Loader), except when writing to disk first! Neither the tool provided support for the api.

    I'm now calling a stored procedure with a collection set however it gives the problem types are NOT taken in charge the following data:

    Nested table, VARRAY/ANYTYPE: gives an error of type 108 unknown column
    index - by table (old style): unknown col.tp. 152
    Clob/NCLOB: unkn.col.tp 112
    BLOB: 113

    All I have left is the stored procedure:

    LONG BELIEVED, GROSS, LONG.

    These data types are not recommended, but at least still supported by 10g.

    So where did that my question, in these circumstances, could you provide me with assistance towards passing the RAW collection /... and interpreting it as a digital table in Oracle. Your help is greatly appreciated.

    Thank you

  • Point cloud with missing data and 3 sets of data

    Hello

    I'm doing a scatter diagram that has 3 sets of data in it (i.e. 3 plots on the same graph), except that 2 of my sets of data have a missing value while my third set has all the values. I end up getting 2 lines that are disconnected. I can't just remove the line containing the missing data for the 2 sets of data because since my category axis is time, my data points get shifted and no longer appear at the right time. This is the chart that I have.

    Thank you.

    Hi Gabrielle,.

    If there is a diagram of dispersion, the x axis is a value axis. If you have auto selected for the min and max values on this axis, the scale may change when you remove the data point, 15, 85, but the rest remains in the same position relative to the values on each axis of ordinates. What change will be , however, is the curve on which 15 85 approached a local y maximum.

    Scatterplots will always leave a gap in the line/curve of connection where there are a pair of missing data. There are two ways to close the gap.

    If the chart is an essentially linear relationship, you can use a calculated value is pair up with the lack of value x. The downside of this is that the representation of this point will be indistinguishable on the map of the other data points, measured.

    A better way would be to make two tables, one with the full data set, the other with the partial sets, but with the pair missing completely removed.

    Adjust the cards the same size and have the same scales on each axis, then just remove one of the cards except the data points, the curves connecting the data points, the x axis of ordinates and the legend showing the color and the forms used to plot each series.

    Give a graphic a transparent filling and place it in front of the other.

    Kind regards

  • With FDM/ERPi of Oracle Data Source incremental data loads

    Hello

    I use ERPi 11.1.2.1. In the workspace, it is possible to set the option of the rule of the data load to be instant, or incremental. However, I use FDM/ERPi set to load data from Oracle GL in Essbase. Is it possible for me to put in place the FDM for the data to load incremental data rules charges? Could be a parameter in the source ERPi adapter?

    Thanks for any information you could provide.

    Yes, the source ERPi adapter there is an option for "Method of Load Data" that will allow you to define how the rule of the DL is run. By default, it is "FULL REFRESH" but can be changed.

    (A) connecting to the application via the workbench and the source system adapters
    (B) make a right click on the Source ERPI adapter and choose "options".

    You will see an option to load method and it will be the full refresh value, choose the value of the option you want in the menu drop-down and save.

  • Fill in the data in an Excel template (with pre-defined formulas) Oracle

    Hello

    Anyone know how I can fill (with PL/SQL) Oracle data in an Excel template (with pre-defined formulas)? I mean that the user provides the Excel model so I just transfer the data from Oracle in particular cells in the worksheet. The model can be large and can become 50 pages long.

    Thank you.
    Andy

    So, you want an Oracle process or a process of APEX to take an existing Excel file and simply plug data into it? What I would say is instead, you export your data out and into your writing Excel VBA code file to take you input file and treat it accordingly.

  • Problem with the date when you load the XML file into Oracle Database 10g

    Hi all

    I have the interface as shown in the screenshot below. In this document, among other things, I am mapping to an element XML file representing a date to an Oracle table column defined as DATE. The source and target columns are highlighted in the screenshot.

    ! http://img223.imageshack.us/img223/1565/odiscr275.jpg!

    When I run the interface, I get the following error message:

    java.lang.IllegalArgumentException to java.sql.Date.valueOf(Date.java:103)

    I guess that this is the conversion of the date!

    I already tried to replace SRC_TRADES. DEAL_DATE with TO_DATE (SRC_TRADES. DEAL_DATE, ' DD/MM/YYYY') on the implementation tab. This feature was not recognized when I executed the interface, so it did not work! The value of date in the XML file is in the format DD/MM/YYYY .

    I guess that Date SQL Oracle functions do not work in the implementation tab. Could someone let me know:

    1. what the Date Conversion function I could use instead?
    2. where can I find a reference to the methods/functions that I use in the implementation tab (if such a reference exists)?

    See you soon.

    James

    Hello.

    Try changing the area of execution at the staging area. Once you change it, write in the map box just SRC_TRADERS. DEAL_DATE. When you use TO_DATE, the source field typu should be varchar2, no date (as it is in store for your data source)

  • AMOUNT of Oracle with the date range

    Hello community,

    I'm having a problem with the addition of a field with a date range. It comes to my table

    JVREFVARCHAR210------
    SOURCEVARCHAR22------
    PERIODVARCHAR26------
    JVDATENUMBER-380-Nullable--
    GLCODEVARCHAR224------
    DESCRVARCHAR240---Nullable--
    AMOUNT_0FLOAT4848--Nullable--
    AMOUNT_1FLOAT4848--Nullable--
    JVTYPEVARCHAR24

    and I'm glad the the following statement works as expected

    SELECT AMOUNT_1 FROM 'TABLE' where

    TO_DATE ("PERIOD, ' YYYYMM") > = to_date ("'201501 ',' YYYYMM")

    and

    TO_DATE (PERIOD, 'YYYYMM') < = to_date ("'201502 ',' YYYYMM");

    E.g.

    AMOUNT_1

    56192.48

    59863.57

    48570.1

    72407.12

    21626.96

    35532.96

    75860.67

    25623.62

    54799.83

    16872.3

    The next thing I want to do is the sum of these amounts... so I changed my statement to become

    SELECT SUM (AMOUNT_1) 'TABLE' where

    TO_DATE ("PERIOD, ' YYYYMM") > = to_date ("'201501 ',' YYYYMM")

    and

    TO_DATE (PERIOD, 'YYYYMM') < = to_date ("'201502 ',' YYYYMM");

    and now I'm getting

    ORA-01841: (full) year must be between-4713 and 9999 and not 0

    I also tried

    SELECT THE PERIOD (AMOUNT_1) SUM OF "BRE". "' OPW_NMLTRX ' where

    TO_DATE ("PERIOD, ' YYYYMM") > = to_date ("'201501 ',' YYYYMM")

    and

    TO_DATE (PERIOD, 'YYYYMM') < = to_date ("'201502 ',' YYYYMM")

    Group by PERIOD

    with the same results... I can't figure out what I should do next?

    Thank you.

    Hello

    Solomon Yakobson says:

    Question:

    SELECT *.

    From your_table

    WHERE the TO_NUMBER (SUBSTR (PERIOD, 1, 4)) NO BETWEEN-4713 and 9999

    OR TO_NUMBER (SUBSTR (PERIOD, 1, 4)) = 0

    /

    To find the offending rows.

    SY.

    This can cause other errors, according to what is in this column.  A better way would be something like:

    Primary_key SELECT, period - add more columns you want

    'TABLE' - avoid names which need quotation marks

    (Period WHERE the TRANSLATION)

    '012345678'

    '999999999'

    ) <> = "999999"

    OR SUBSTR (period, 1, 4), not BETWEEN "1900" AND "2099"

    OR SUBSTR (period 5) NOT BETWEEN '01' to '12'

    ;

    Now there may be errors of conversion, because there is no conversion.

  • problem with implicit to the conversion of the date in oracle

    SELECT ROUND('12-FEB-2010') FROM DUAL; -gives error

    It needs explicit conversion using TO_DATE();

    My question is why what is happening?
    Is it because we have two functions ROUND (NUMBER) and ROUND (DATE)?

    Hello

    Welcome to the forum!

    user650693 wrote:

    All of the built-in functions will work fine as long as use you them as directed; in particular, pass arguments that have the correct data type. If a function requires a DATE for an argument, always place a DATE, not a VARCHAR2 you hope will be be implicitly converted to DATE.

    D MY separator2 R separator1

    the separator can be any sign of punctuation (/ $ % & *, ^) sapces, tabs...

    This applies to explicitly call the functions where a format string is used, for example, TO_DATE.

    as
    Select ADD_MONTHS('21$MAY*2010',2) from DUAL;

    SELECT MONTHS_BETWEEN ('23 ^ FEB & 2010', ' 11% jan(2011') FROM DUAL;)

    the two works perfectly,

    As the respondent previous said, the two work may , depends on several factors, such as your NLS parameters. It's a very bad habit to rely on such things. The 1st argument to ADD_MONTHS and two arguments to MONTHS_BETWEEN, are supposed to be DATEs, so always call these functions with the DATEs.

    but this does not work in the ROUND functions (date) and TRUNC (date);
    SELECT ROUND('12-FEB-2010') FROM DUAL; -gives error

    It needs explicit conversion using TO_DATE();

    My question is why what is happening?
    Is it because we have two functions ROUND (NUMBER) and ROUND (DATE)?

    No, it's because there is no ROUND function (VARCHAR2).
    The use of strings which are expected of the DATEs is simply asking for trouble. Sometimes, you get what you're asking.

  • I have a new backup disk (a disk of 5 TB of Seagate) and need help setting up with CCC!

    Hello world

    I have a new backup disk (a disk of 5 TB of Seagate) and could use help setting up with CCC.

    I did in the past without problem, but I want to assure you of a few things:

      1. This particular drive has software available in a folder on the disk backup (w / the PC and Mac versions). But... I intend to use this disk as an exact copy of my iMac HD; It must also be bootable.
      2. Should I format the drive with disk utility? Or load the software to the CCC on the disk and just leave their only backup software?
      3. One last question: I also have a MacBook Air, an iPad and an iPhone. I want to save them as well. Should I put them on separate partitions, I created? Or can we just one big happy family? The last is best.

    One last piece of information: two computers, etc, were all backed up via Time Machine. My data the most important, photos, etc., are also saved on deposit box and/or iCloud on a regular basis.

    Thanks for any suggestions or comments!

    Sally D.

    Delete and partition the drive by making a separate partition for each computer. The iPad and the iPhone is useless their own partition because they back up using iTunes and would appear in the clone of the computer that you use for each save. Each partition must be the size of the current cloned drive that can leave you with additional partitions for other stuff. Then format the drive Mac OS Extended journaled. Do not install any software that came with the drive, none of this is necessary.

    I use a very similar setup with a 3 TB drive. I clone my boot SSD in a single partition, my drive internal 1 Tb in a second, my Macbook to a third party, and I have a fourth partition which is currently empty, because I haven't decided what to do with it yet. I also have a 3 to Apple Time Capsule.
