Join several tables of two different patterns - is it possible?

If this is the case, what are the measures?

THX

This is the case.

You must prefix the tables with the schemaname tables is in, or create a synonym for the table. In addition, you must grant select rights from of a the reference schema owner schema:

SELECT A.*,B.*
  FROM SCHEMA1.TEST_TABLE A,
       SCHEMA2.TEST_TABLE B
 WHERE somecondition

  • Join several Tables versioned

    Hello

    We are working on a data warehousing project and wonder how do to join several tables that each are versioned separately (type SCD 2 with a valid and valid to date).

    Because for example, we get our client from a single source of information (id customer, name, etc.) and the information on the rate of customer from another source.  The sources are different, we have the separate tables for them and each of them gets versioned independently.

    Here's my customer table (with its own valid and valuable to the columns).

    IDName of the customerValid fromValid until the
    1CitiBank1 JANUARY 14JANUARY 1, 15
    1New CitiBank2 JANUARY 15FEBRUARY 1, 15
    1Latest CitiBank2 FEBRUARY 15APRIL 1, 15

    And similarly the Client side ID and rating information.

    IDNoteValid fromValid until the
    1Platinum1 JANUARY 14FEBRUARY 1, 14
    1PremiumFEBRUARY 1, 141ST MARCH 15

    I want to merge the two tables above and present information at a glance.  I have some difficulty to determine validates the valid columns.

    IDName of the customerNoteValid from (Calculated)Valid until the (calculated)
    1CitiBankPlatinum1 JANUARY 14FEBRUARY 1, 14
    1CitiBankPremiumFEBRUARY 1, 14JANUARY 1, 15
    1New CitiBankPremium2 JANUARY 15FEBRUARY 1, 15
    1Latest CitiBankPremium2 FEBRUARY 151ST MARCH 15

    And it's the query I used to get the above result:

    SELECT client. id ,

           customer . name ,

           CRM . level ,

           Greatest (client. vld_fm , crm. vld_fm ),

           Least (client. vld_to , crm. vld_to )

    DE    client client,

           client_rating crm

    OÙ   client. id = crm. id

           AND ( client. vld_fm <= crm. vld_fm

                 AND client. vld_fm <= crm. vld_to

                 AND client. vld_fm >= crm. vld_fm

                 AND client. vld_fm >= crm. vld_to )

            OR ( client. vld_fm BETWEEN crm. vld_fm AND crm. vld_to )

            OR ( client. vld_to BETWEEN crm. vld_fm AND crm. vld_to );



    The problem is we have several data sources (and each with its own versions) and joins become so very very complex.  Is there a better way to write the query?

    Or maybe a better way to design our tables?

    Thanks for your help.

    Hello

    you only need ranges that overlap to join.

    Re: How do to sql query in a loop

    Is a simpler way to test if the x_start to x_stop range comes into conflict with the range of y_start to y_stop

    WHERE     x_start <= y_stop AND     y_start <= x_stop

    In other words, two overlapping if and only if everyone will start before the other ends one. If this is not obvious (and it was certainly not clear to me when I heard it), then look at it this way: two ranges are not overlapping if and only if one of them starts after the end of the other.

    Now for the tables A and B I have the simple join as condition

    Now, I have to use

    (trim (b.UPPERMATERIALCODE)). » -'|| Trim (b.PROCESSNO) = Trim (c.PRODUCTIONCODE) | » -'|| Trim (c.REVISIONNO)

    condition to get the data for the WAVY and DRUMTYPE1 fields.

    But at the same time, I have to use

    substr (Trim (b.UPPERMATERIALCODE), 1, 2). » -'|| Trim (b.PROCESSNO) = Trim (c.PRODUCTIONCODE) | » -'|| Trim (c.REVISIONNO)

    conition to derive the CHAFER field.

    And for this reason I am come so many duplicates and do not correct results for JUNEBUG, WAVY, DRUMTYPE1, and STARTDATE field.

    I need some advice as how can I do so that I get the correct results without duplicates for the PRIMARY KEY.

    Thank you

    Mahesh

    It would have been easier to answer if you gave us your example query that gives incorrect results - which both show us what you are doing and give us a starting point.
    Insert instructions for data, rather than only the data would have helped too, making it more quick to test this point.
    You do not show what you have done with your two outer join criteria, but I think you need to list TIREMASTERPROCESS_TEMP in your query twice, with alias names. Here's what I did:

    select a.BUILDINGSIZE, a.GTCODE, b.PROCESSNO ,  c1.FIELDNAME, c1.DATACHR, C2.FIELDNAME, C2.DATACHR
, CASE WHEN c1.FIELDNAME='BTDrumNo1' then c1.DATACHR end drumtype1
, CASE WHEN (trim(c2.DATACHR) = '1' and trim(c2.FIELDNAME) = 'No-of-Nch') THEN 'YES' ELSE 'NO' END CHAFER
, case when c1.FIELDNAME='Wavy' AND c1.DATACHR='Use' THEN 'YES'
       when c1.FIELDNAME='Wavy' then 'NO' else null end wavy
from BUILDINGSCHEDULEMASTER        A
join materialcode b on a.GTCODE=b.UPPERMATERIALCODE
left outer join TIREMASTERPROCESS_TEMP c1
   ON trim(b.UPPERMATERIALCODE)||'-'||trim(b.PROCESSNO) = trim(c1.PRODUCTIONCODE)||'-'||trim(c1.REVISIONNO)
left outer join TIREMASTERPROCESS_TEMP c2
   ON substr(trim(b.UPPERMATERIALCODE),1,2)||'-'||trim(b.PROCESSNO) = trim(c2.PRODUCTIONCODE)||'-'||trim(c2.REVISIONNO)

    C1 is an alias for the TIREMASTERPROCESS_TEMP line which is necessary for drumtype1 and wavy, c2 is an alias for the TIREMASTERPROCESS_TEMP line required for JuneBug. There was some minor errors in your calculations of field I tried to correct.

    The results are:

    BUILD GTCO PRO FIELDNAME    DATACHR    FIELDNAME    DATACHR    DRUMTYPE1  CHA WAV
----- ---- --- ------------ ---------- ------------ ---------- ---------- --- ---

  • Two constraints of primary key of a table with two different constraint name

    Hi guys

    I am creating the table below

    Table name: TITLE_COPY

    Column name Copy_id Title_id Status

    Key type

    		PKPK, FK
    UniqueNN, UNN, UNN
    CheckAvailable, destroyed, leased, reserved
    Table Ref FKTitle
    FK Ref ColTitle_id
    Data typeNumberNumberVarchar2
    Length101015

    The SQL statement below can create it

    CREATE TABLE title_copy (copy_id NUMBER (10),)

    title_id CONSTRAINT NUMBER (10) title_copy_title_id_fk title (title_id) REFERENCES.

    primary key constraint title_copy_title_id_pk title_id (copy_id)

    status VARCHAR2 (15) NOT NULL CONSTRAINT status_ck CHECK (status IN ('AVAILABLE', 'DESTROYED', 'RENTAL', 'RESERVED'))

    );

    Two primary keys (title_id, copy_id) are created with the same name of constraint (title_copy_title_id_pk) (-> table-level constraint). What happens if I want to have two different names of the primary key constraint, say title_copy_title_id_pk for the title_id column and title_copy_copy_id_pk for the copy_id column?

    I can do that with a column-level constraint? Something like below (complains about the additional primary key)

    CREATE TABLE title_copy (copy_id NUMBER (10) CONSTRAINT title_copy_copy_id_pk PRIMARY KEY,)

    constraint title_copy_title_id_pk primary key (title_id).

    title_id CONSTRAINT NUMBER (10) title_copy_title_id_fk title (title_id) REFERENCES.

    status VARCHAR2 (15) NOT NULL CONSTRAINT status_ck CHECK (status IN ('AVAILABLE', 'DESTROYED', 'RENTAL', 'RESERVED'))

    );

    In summary, I can define two primary keys with the name of different constraint in a column-level constraint?

    There are no two primary keys. There is a primary key made up of two columns - also called a composite key.

    A table can have at least a primary key. You can, if you wish, create a unique constraint on a different set of columns.

  • M476dn: Printer in two different networks - is it possible?

    I got the following requirement:

    Printing from iPad should be possible on one of our network printers. As known, Apple Airprint is available only via WiFi. Question: Network printers are in another network than iPads.

    My idea:

    -Buy a Wifi capable HP printer network (for example. M476dn)

    -Configure the LAN port for normal office network (printer connected to the network via a cable)

    -Configure the printers WiFi interface for the Wifi network, which is used by iPads

    Then the PC and laptops should be able to print via normal office network (print server) and iPads via Airprint.

    Question: Is it possible to set up a printer HP in this way, so that it is located in two different networks? Especially the M476dn this would support? I would like to clarify this point of course before buying a ;-)

    In fact the user must move the network for printing.

    It is the only possible option I can think, other then get a different printer for each network.

    Kind regards

    Here is an explanation of the output.  a user will have a front screen where it can enter itemlist info.
    then in a submenu may enter a category or sub or both or none of them. the user can select multiple categories or sub
    When the user presses the button Save, an entry will be made in the itemlist table, for example the cid = 1.
    If he choose a category but without Subs, then will be entered into the table at say cid = 1


    but no entries will be made for sub because he chose not to all values.  If he chooses void instead of category values
    then sub taable will fill and category is not. If he chooses the category and under, then both will be filled.

    what I want to do is to join the itemlist with table category and sub table and get the data to the Scriptures, this intervention of the user.
    These entries not found will be the null value column in the result.
    for example, the cid = 1 itemlist, if user enter category but not void, itemlist will be the join with the table category and sub
    but since sub has no entry for the cid = 1, the column object will be empty in the output, but catcode will fill

    I'm so confused.

    It is a query (that is, just a SELECT statement, which shows the data already present in the tables), or is this a DML statement, that will add data to the tables?  If it's just a query, then do not say things like "entries will be taken" or "filled with tables.

    Assuming you want a request maybe you want something like this:

    WITH c_and_s AS

    (

    SELECT NVL (c.cid, s.cid) AS cid

    NVL (c.sub, s.sub) AS topic

    , NVL2 (s.cid, c.catcode, NULL) AS catcode

    CATEGORY 1 c

    FULL OUTER JOIN void s ON c.cid = s.cid

    AND c.sub = s.sub

    )

    SELECT i.cid, i.listname, i.flg

    cs.subject, cs.catcode

    Itemlist I have

    LEFT OUTER JOIN c_and_s ON cs.cid = i.cid cs

    WHERE the i.cid (1) - you can do the cids 2 or several at the same time, if you want to

    ORDER BY i.cid, cs.subject, cs.catcode

    ;

    This example gets the output you asked data sample you posted.

  • How to join several tables source and do the research?

    I have a requirement to load a target table by joining 4 source tables. Also, I do a search on a field of table to transform codes and check for NULL values. What will be the best approach for load table target?
    Is it possible to do it in a single interface, or do I need to create multiple interfaces to achieve this?

    My basic source and target are oracle, and I am planing to use incremental update Oracle merge.

    Thank you

    You are in the right direction by creating an interface for this transformation.
    You will need to drag the source drop 4 tables + the lookup table in the Sources of Interface window and then make the appropriate joins.
    Also, look for NULL values in the transformation. Depends on what you want to do with NULL values. If you want to ignore, use a filter.
    If you want to make mistakes, use a constraint.
    If you want to convert them, use NVL

    Start with Oracle Update incremental and once successful, use incremental update Oracle MERGE.

  • Comparing the same tables of two schemas

    I had already posted a similair on this thread. So, I thought I would start a new thread on this to avoid confusion

    I want to generate a report that shows the difference in the data type of the columns in the same table in two different patterns.

    The query using LESS shows the difference below.

    create table SCOTT.mytab1 (empid number);
create table HR.mytab1 (empid varchar2(34));


SELECT   table_name, column_name, OWNER schema, data_type
FROM     dba_tab_cols where owner = 'SCOTT'
AND TABLE_NAME = 'MYTAB1'
MINUS
SELECT   table_name, column_name, OWNER schema, data_type
FROM     dba_tab_cols where owner = 'HR'
AND TABLE_NAME = 'MYTAB1'

Result:
TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
--------------- --------------- ---------- ------------
MYTAB1          EMPID           SCOTT      NUMBER
    But, since it is a report, I want to see the form of results the two schemas that has column of different data types with the same names of table

    Expected results:
    TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
--------------- --------------- ---------- ------------
MYTAB1          EMPID           SCOTT      NUMBER
MYTAB1          EMPID           HR         VARCHAR2
    Anyway I could do this?

    Why not get a single line with two types of data:

    select a.table_name, a.column_name, a.data_type schema1_type, b.data_type schema2_type
from all_tab_columns a, all_tab_columns b
where a.owner = 'SCOTT'
and b.owner = 'HR'
and a.table_name=b.table_name
and a.column_name=b.column_name
and a.data_type!=b.data_type;

    This extracted single query columns present on the two schemas but with different data types. These columns only on one of the two schemas are not extracted.

    Please see the attached link for table structures and data of the sample.

    There will be several lines in the table of SALES with different SALETYPEs. There may be several lines in the table RETURNS, corresponding to some of the points of SALE. RETURNS the table has a foreign key to the SALE. The report that I am trying to generate with a select sql statement must include a line for each type of sale (from table SALETYPE) and the sum of sale amounts corresponding to this type of sale of the SALES table. The table may not return the entries for all types of sales and the amount of Scripture must be reported as zero. The SQL I use is below, but does not work. I hope that I have explained this correctly. Please see the doc attached for typical data that I work with. Can someone please?
