Für SQL Select * where max (date) < bestimmtes Datum

Hello

I need help to create a SQL statement for the following scenario:

History of the table

Process of Date_updated
Process 125.03.2014
Process 120.03.2014
Process 110.03.2014
Process 210.03.2014
Process 201.03.2014
Process 305.03.2014

I want to get all processes what update is earlier than 15.03.2014.

So, the result would be:

-Process 2-> last update = 10.03.2014

-Process 3-> last update = 05.03.2014

How can I achieve this? with something like where max (date_updated) < = to_date('15.03.2014','dd.mm.yyyy') group by process, it does not work

Try HAVING to place WHERE.

SEPARATE is redundant.

  • Select Max (date) between multiple tables

    I need to retrieve a record from a Table in a set of similar tables with a common "date field". You can select the record where this "date field" value is greater between multiple tables.

    Here, any help is appreciated.  Thank you in advance.

    FOR EXAMPLE

    No. EMP is the primary key.

    Again, each table can have multiple records for EMP n ° 1

    TABLE1:

    FIRST NAME

    FAMILY NAME
    THE EMP NO.

    BASE SALARY

    DATE_FROM

    TABLE 2

    FIRST NAME

    FAMILY NAME
    THE EMP NO.

    SALARY GRADE

    DATE_FROM

    TABLE 3

    FIRST NAME

    FAMILY NAME
    THE EMP NO.

    COMPENSATION

    DATE_FROM

    Hello

    Said Knani, if you use the current design of the table, then here is a way to do what you want:

    WITH union_data AS

    (

    SELECT MAX (base_salary) AS sal FROM table1 UNION ALL

    SELECT MAX (grade_salary) table2 UNION ALL

    SELECT MAX (compensation) FROM table3

    )

    SELECT MAX (sal) AS max_sal

    Of union_data

  • ORA-28500 + 'String data, right truncation' when selecting nvarchar (max)

    Hello

    I was able to put in place a db Oracle 11.2.0.1 link to SQL Server 2005 using DG4ODBC.

    When you try to select a column with the data type of nvarchar (max) in the db link I get the following error:
    ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][SQL Native Client]String data, right truncation {01004}[Microsoft][SQL Native Client]String data, right truncation {01004}[Microsoft][SQL Native Client]String data, right truncation {01004}[Microsoft][SQL Native Client]String data, right truncation {01004}[Microsoft][SQL Native Client]String data, right truncation {01004}
ORA-02063: preceding 2 lines from SQLSERVER_DBLINK
    The actual data in the column do not exceed 31 characters, but the application still does not work.

    Any suggestions?
    Thank you.

    checked with DataDirect ODBC driver that returns for col2 = nvarchar (max) and col3 = varchar (max)

    Entry hgopcda at 2010/12/23-11: 55:17
    Column:2 (col2): dtype:-10 (WLONGVARCHAR), prc / scl:1073741823 / 0, nullbl:1, radix: 0 byte: 2147483647, sign: 1

    Out of hgopcda, rc = 0 to 2010/12/23-11: 55:17

    This driver correctly fills the buffer (0 no equal) and function of the buffer the gateway decided to map it to:
    DTY NULL-OK LEN MAXBUFLEN PR/SC CSE IND MOD NAME
    12 Y VARCHAR 20 20 0 / 0 0 0 200 col1
    -1 LONGVARCHAR Y 0 0 0 / 0 0 0 220 col2
    -1 LONGVARCHAR Y 0 0 0 / 0 0 0 220 col3

    and in Oracle when performing a describe statement I see the column as LONG.

    This type of mapping from nvarchar to LONGVARCHAR works in Dg4ODBC if the Oracle DB character set = Unicode. => and you meet this requirement.

    ==>> If it looks like a driver problem, and it might be useful to use a different driver.

  • Select the year max and max date for a code

    Hello

    I need to extract max year and month max for one code particulare.

    My table contains:

    YEAR MONTH CODE

    ====   =====    ====

    2014 6 X

    2014 7 X

    2013 5 Y

    2013 6 Y


    I need to extract:


    2014 7 X

    2013 6 Y


    I don't like max(YEAR|| le mois), I want the column separated.


    Thank you

    Try this:

    WITH test_data AS (
  SELECT 2014 AS yr, 6 AS mth, 'X' AS code FROM DUAL
  UNION ALL
  SELECT 2014 AS yr, 7 AS mth, 'X' AS code FROM DUAL
  UNION ALL
  SELECT 2013 AS yr, 5 AS mth, 'Y' AS code FROM DUAL
  UNION ALL
  SELECT 2013 AS yr, 6 AS mth, 'Y' AS code FROM DUAL
)
SELECT yr
     , MAX(mth) KEEP (DENSE_RANK FIRST ORDER BY 100*yr+mth DESC) AS mth
     , MAX(code) KEEP (DENSE_RANK FIRST ORDER BY 100*yr+mth DESC) AS code
FROM   test_data
GROUP BY yr
ORDER BY 1;

    Obviously by storing your dates as the DATE, then ranked by who would be more elegant!

  • Select Max (Date) in two different tables...

    Dear all,

    I need the date of last update of two different tables, I mean max (date). We will update one table at a time. Updated once I need to take the last update.

    It can be either in table A table B.

    for example.

    Table A

    Date of the ID

    100 16/05/2014

    101 20/05/2014

    102, 22/05/2014

    Table B

    Date of the ID

    100 04/06/2014

    101, 26/05/2014

    102 21/05/2014

    I need the date of table B (101 26/05/2014) last updated date...

    Hello

    Another way, using much more GRAND:

    SELECT LARGER (max1, max2) x

    FROM (SELECT MAX (mydate) max1

    OF mytable_a

    )

    (SELECT MAX (myotherdate) max2

    OF mytable_b

    Currently I am working on a site where users should be able to load the data of csv (comma is the separator) of their client machines (APEX 3.2 application) in the Oracle 11.2.0.4.0 EE database.

    My problem is:

    I can't use an external table (for the first time in my life ) so I'm a little clueless what to do as the csv data is stored by the application of the APEX in a BLOB column, and I'm looking for an elegant way (at least SQL PL/SQL/maximization) to insert the data into the destination table (run validations by a MERGER would be the most effective way to do the job).

    I found a few examples, but I think they are too heavy and there could be a more elegant way in Oracle DB 11.2.

    Simple unit test:

    drop table CBC purge;

    drop table dst serving;

    create table src

    (myblob blob

    );

    create table dst

    (num number

    , varchar2 (6) str

    );

    Insert in src

    Select utl_raw.cast_to_raw (1; AAAAAA ;'|| Chr (10) |

    2; BATH; »

    )

    Double;

    Desired (of course) output based on the data in table SRC:

    SQL > select * DST;

    NUM STR

    ---------- ------

    1 ABDELKRIM

    2 BATH

    Does anybody know a solution for this?

    Any ideas/pointers/links/examples are welcome!

    / * WARNING: I was 'off' for about 3 months, then the Oracle - the part of my brain has become a bit "rusty and I feel it should not be so complicated as the examples I've found sofar ' * /"

    Haha, wonder about regexp is like the blind leading the blind!

    However, it's my mistake: I forgot to put the starting position setting (so 1, 2, 3,... was in fact the starting position, not the nth occurrence. duh!)

    So, it should actually be:

    select x.*
,      regexp_substr(x.col1, '[^;]+', 1, 1)
,      regexp_substr(x.col1, '[^;]+', 1, 2)
,      regexp_substr(x.col1, '[^;]+', 1, 3)
,      regexp_substr(x.col1, '[^;]+', 1, 4)
,      regexp_substr(x.col1, '[^;]+', 1, 5)
,      regexp_substr(x.col1, '[^;]+', 1, 6)
from  src
,      xmltable('/a/b'
              passing xmltype(''||replace(conv_to_clob(src.myblob), chr(10), '')||'')
              columns
                col1 varchar2(100) path '.') x;

    Note: that's assuming that all the "columns" passed in the string won't be lame.

    If one of them might be null, then:

    select x.*
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 1)
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 2)
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 3)
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 4)
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 5)
,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 6)
from   src
,      xmltable('/a/b'
              passing xmltype(replace(';'||replace(conv_to_clob(src.myblob), chr(10), ';')||'', ';;', '; ;'))
              columns
                col1 varchar2(100) path '.') x;

  • ODI - SQL for Hyperion Essbase data loading

    Hello

    We have created a 'vision' in SQL Server that contains our data.  The view currently has every year and periods of Jan 2011 to present.  Each period is about 300 000 records.  I want to only load one period at a time.  For example may 2013.  Currently we use ODBC through a rule of data loading, but the customer wants to use ODI to be compatible with the versions of dimension metadata.  Here's the SQL on the view that works very well.   Is there a way I can run this SQL in the ODI Interface so it pulls only what I declare in the Where clause?  If yes where can I do it?

    Select

    CATEGORY, YEAR, LOCATION, SCRIPT, DEPT, PROJECT, EXPCODE, TIME, ACCOUNT, AMOUNT

    Of

    PS_LHI_HYP_PRJ_ACT

    Where

    YEAR > = "2013" AND PERIOD = 'MAY '.

    ORDER BY CATEGORY ASC ASC FISCAL_YEAR, LOCATION ASC, ASC, ASC, ASC, ASC, PERIOD EXPCODE PROJECT DEPT SCENARIO CSA ACCOUNT CSA;

    Hello

    Simply use the following KM to load data - IKM SQL for Hyperion Essbase (DATA) - in an ODI interface that has the view that you created the Source model. You can add filters to the source which are dynamically by ODI variables to create the Where clause based on the month and year. Make sure you only specify a rule of load method to load the data into the KM

  • selection of the dates not used for the list

    OK, the last one for today...

    I'm trying to fill a list with values of the month years between the first entry in the table and the month previous (sysdate - 1 month).

    At the moment I have this, which will select every month between the last entry in the table and sysdate-1.
    select to_char( add_months( start_date, level-1 ), 'MON-YY' ) d, to_char( add_months( start_date, level-1 ), 'MON-YY' ) r
from (select add_months(max(date_received),1) start_date, add_months(sysdate, -1) end_date from localdata) where start_date < end_date
connect by level <= months_between(trunc(end_date,'MM'), trunc(start_date,'MM') ) + 1
    But I want it uses the first entry and select all the months between then and sysdate-1 where there is no entry in the table.

    I tried something like that, but it returned no data:
    select to_char( add_months( start_date, level-1 ), 'MON-YY' ) d, to_char( add_months( start_date, level-1 ), 'MON-YY' ) r
from (select min(date_received) start_date, add_months(sysdate, -1) end_date from localdata) where start_date < end_date and to_char(start_date, 'MON-YY') not in (select to_char(date_received, 'MON-YY') from localdata)
connect by level <= months_between(trunc(end_date,'MM'), trunc(start_date,'MM') ) + 1

    Thanks for the comment tip, it works great now. I just need how to sort date wise.

    If missing_month is a string, such as "JAN-2013", then it's not good for sorting, since the string "JAN-2013" come after "FEB-2013"(et aussi après «FEB-2014"et «FEB-2015") because 'J' comes after 'F'. "»»» If you want to sort, and then keep the month as a DATE, like this:

    WITH     got_missing_month_s     AS
(
     SELECT     ADD_MONTH first_month, LEVEL - 1)     AS missing_month_s
     FROM     (
               SELECT TRUNC ( MIN (date_received)
                                       , 'MONTH'
                              )          AS first_month
               FROM   localdata
          )
     CONNECT BY     LEVEL     <= MONTHS_BETWEEN ( SYSDATE
                                             , first_month
                                      )
    MINUS
        SELECT  TRUNC (date_received, 'MONTH')
     FROM     localdata
)
SELECT       TO_CHAR (missing_month_s, 'MON-YYYY')     AS missing_month_d
,       missing_month_s
FROM       got_missing_month_s
ORDER BY  missing_month_s
;

    The main request has 2 columns:
    missing_month_d is for display: it's a string such as "JAN-2013".
    missing_month_s is for sorting: it's a DATE.

  • Select table Max

    Dear all,

    I have table userstat

    OUTPUT MUST BE
    27/10/2012 10:08:23 XYZ FAILED
    27/10/2012 12:08:23 DEF FAILED

    Thanks in advance.

    Test data:

    create table USERSTAT (CREATE_DATE, USERNAME, REPLY_MESG) as select
TO_DATE('27-10-2012 10:10:10', 'dd-mm-yyyy hh24:mi:ss'), 'ABC', 'FAILED' from DUAL union all select
TO_DATE('27-10-2012 10:20:10', 'dd-mm-yyyy hh24:mi:ss'), 'ABC', 'FAILED' from DUAL union all select

to_date('27-10-2012 12:08:23', 'dd-mm-yyyy hh24:mi:ss'), 'DEF', 'FAILED' from dual;

    Solution:

    select * from (
  select USERNAME, max(CREATE_DATE) CREATED_DATE,
  max(REPLY_MESG) keep (dense_rank last order by CREATE_DATE) reply_mesg
  from USERSTAT
  group by USERNAME
)
where reply_mesg = 'FAILED';

USERNAME CREATED_DATE REPLY_MESG
-------- ------------ ----------
DEF      10/27/2012   FAILED
XYZ      10/27/2012   FAILED

    Explanation: you seem to be the most recent record for each user name. If you want just the most recent date, max (create_date) would be enough, but you also need the response message. The DUNGEON (DENSE_RANK LAST function basically said 'Give me the response message which corresponds to the last CREATE_DATE', which is what you want.

    Note Please I am simplifying here: there may be multiple records with the last CREATE_DATE, that's why it is a function of aggregation , with max() around REPLY_MESG.

    The final WHERE clause keeps records where the last response message was 'IMPOSSIBLE '.

  • filling of datetime column SQL Server with the data in the date column oracle

    After a lot of "finangling", I think I have my link dg4msql works well between Oracle and MSSQL.

    Now, what I'm trying to do, is fill a table in MSSQL with an Oracle table column values, whenever a new row is inserted in the Oracle table. I use a very simple trigger on the oracle table that goes basically like this:

    mware is dblink to MSSQL database, oracle col worth DATE and mssql col is of type DATETIME

    This is the relaxation: (edited to show only the column in question)
    ==================================================================================
    CREATE or replace TRIGGER < oracleowner >. INSERT_INTO_NVDB
    AFTER INSERT ON < oracleowner >. < oracletable > for each row
    BEGIN
    insert into '< mssqlowner > '. «< mssqltable > @mware «»
    (
    "load_date_time,"
    )
    VALUES)
    : new.loading_date,.
    );

    END;
    ==================================================================================

    Now, when you enter a record in the Oracle trigger triggers ok table but does not insert a date in the MSSQL table, the 'load_date_time' in the mssql table can have NULL values so I guess there just inserts a null value.

    When I activate the triggers on the table MSSQL, which then takes these values and inserts them into another table with values from other tables, inserting in the Oracle table fails because the relaxation on the MSSQL database tries to pass the date (which is empty) table MSSQL in another table where the datetime field is not null.

    I guess it's because Oracle date format is not compatible with MSSQL, which I think is "yyyy-mm-dd hh: mm:"- so I have to either convert the date format by default Oracle to match a MSSQL, or convert a char of the trigger value. (The developer of the side MSSQL says if I can convert it to a char value that should be ok too)

    I think that it is probably better to leave it in the date format, the best way to do this would be to put an "alter session set nls_date_format ="at the beginning of the trigger?

    Can I convert the date to char the trigger easily? If there is a better way to proceed in the way I approach it I'm all for it.

    Thank you!

    Hello
    Your best option is to explicitly convert dates Oracle in a format recognized by SQL * Server. It's more coding, but then you know exactly what is being inserted and you give more control, if anything changes. You can also code to handle null data.
    I'm not sure than to try to change the format of date to 'alter session... ". "do what you want.
    You can use "to_char" on a date into character data-

    To_char (, "HH24:MI:SSxFF of MON-DD-YYYY")

    and use any mask format supported.
    You also use 'to_date' to transform the character data in a date format, as well as 'to_char' and 'to_date' in combination.
    For example -.

    SELECT TO_CHAR (TO_DATE (October 27, 98 ',' DD-MON-RR'), 'YYYY') 'Year' FROM DUAL;

    This is all discussed in the documentation-

    Oracle® database
    SQL language reference
    11g Release 2 (11.2)

    where it also describes the different format masks.
    If you need further assistance on the use of to_date, to_char formats then ask in the forum SQL/PLSQL.

    SQL and PL/SQL

    where they have more experience.

    Kind regards
    Mike
