Join two tables which stored in difference database

Hi, i have a problem how to join two tables which are stored in difference databases. I'm using MS access and need to use Jsp to solve it. is anyone have idea to solve it. thxx

Hi,
I think you cannot join the tables which are in two diff databases. You have to connect to each database ,get the result and manipulate in your program. Use a bean.

Join two tables to query the difference of both

Hi,
I think my problem is not the hardest, but I don't find a solution.
- i have two tables: t_old, t_new
- both have the same attribute (item_nr)
- t_new exists of some rows from t_old and some new rows
I want to query only the new rows from t_new, that aren't in the table t_old.
Who can help me please..???
Regards,
Steffen

wrong forum, sorry, but i got it in another forum:
select * from t_new n
where not exists
(select 1 from t_old o
where n.item_nbr = o.item_nbr)
(THX to Keith Jamieson)
or
select * from t_new
minus
select * from t_old
(THX to Boneist)

How to prevent Oracle from using an index when joining two tables ...

How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
O.K. I think I have to explain what I mean:
When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
I have two tables: table A and table B.
Table A has 4.000.000 entries and table B has 700.000 entries.
I have a join of both tables with a numeric column as join criteria.
There is an index on this column in table A.
So I instead of
where (A.col = B.col)I want to use
where (A.col+0 = B.col)in order to prevent Oracle from using the index.
When I use the join in a select statement it works.
But when I use the join as inline view in an update statement I get the error ORA-01779.
When I remove the "+0" the update statement works. (The column col is unique in table B).
Any ideas why this happens?
Thank you very much in advance for any help.
Regards Hartmut

I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.

Joining two tables having no common fields using one select query

Hi Experts,
How to join two tables which are NOT having any field in common using only one select query?
Your help will be appreciated.
Thank you.

Identify a third table (or more tables) with common fields with your two tables, or change your question either removing JOIN or removing NO COMMON FIELDS, else you wont get many responses and will be left alone in outer space, as suggested by Thomas.
If you acturally require what you written, better execute two select and merge the two internal tables merging every record from first table with every record of second table, til no more memory is available.

Need help to join two tables using three joins, one of which is a (between) date range.

I am trying to develop a query in MS Access 2010 to join two tables using three joins, one of which is a (between) date range. The tables are contained in Access. The reason
the tables are contained in access because they are imported from different ODBC warehouses and the data is formatted for uniformity. I believe this cannot be developed using MS Visual Query Designer. I think writing a query in SQL would be suiting this project.
ABCPART links to XYZPART. ABCSERIAL links to XYZSERIAL. ABCDATE links to (between) XYZDATE1 and ZYZDATE2.

Thank you for the looking at the post. The actual table names are rather ambiguous. I renamed them so it would make more sense. I will explain more and give the actual names. What I do not have is the actual data in the table. That is something I don't have
on this computer. There are no "Null" fields in either of the tables.
This table has many orders (MSORDER) that need to match one order (GLORDER) in GLORDR. This is based on MSPART joined to GLPART, MSSERIAL joined to GLSERIAL, and MSOPNDATE joined if it falls between GLSTARTDATE and GLENDDATE.

Joining Two Tables by Database View

HI There,
I'm trying to join two tables BNKA and LFBK to get the Bank details according to the requirement.
Now, I wanted to go head and create a Generic datasource and bring the fields from these two tables by Vew.
Can someone please explain me step by step to create the database view?
One more thing, do we need to have anything in common between two tables BNKA and LFBK ?
I really appreciate if someone can guide me through step by step method to create Database Table view?
Thanks
Madhuri

Hi Madhuri,
With out having common fields, we can not create data base view based on two tables.
1) goto SE11
2) select data base view and give the name and create.
3) in left side give the tables names
4) In left side define the relation
check the below article

How to join two tables

hi
how to join two tables using inner join if the first table has two primary keys and second table has 3 primary keys

Would describe type of joins in ABAP, which might differ with other joins.
The join syntax represents a recursively nestable join expression. A join expression consists of a left-hand and a right- hand side, which are joined either by means of INNER JOIN or LEFT OUTER JOIN. Depending on the type of join, a join expression can be either an inner (INNER) or an outer (LEFT OUTER) join. Every join expression can be enclosed in round brackets. If a join expression is used, the SELECT command circumvents SAP buffering.
On the left-hand side, either a single database table, a view dbtab_left, or a join expression join can be specified. On the right-hand side, a single database table or a view dbtab_right as well as join conditions join_cond can be specified after ON. In this way, a maximum of 24 join expressions that join 25 database tables or views with each other can be specified after FROM.
AS can be used to specify an alternative table name tabalias for each of the specified database table names or for every view. A database table or a view can occur multiple times within a join expression and, in this case, have various alternative names.
The syntax of the join conditions join_cond is the same as that of the sql_cond conditions after the addition WHERE, with the following differences:
At least one comparison must be specified after ON.
Individual comparisons may be joined using AND only.
All comparisons must contain a column in the database table or the view dbtab_right on the right-hand side as an operand.
The following additions not be used: NOT, LIKE, IN.
No sub-queries may be used.
For outer joins, only equality comparisons (=, EQ) are possible.
If an outer join occurs after FROM, the join condition of every join expression must contain at least one comparison between columns on the left-hand and the right-hand side.
In outer joins, all comparisons that contain columns as operands in the database table or the view dbtab_right on the right-hand side must be specified in the corresponding join condition. In the WHERE condition of the same SELECT command, these columns are not allowed as operands.
Resulting set for inner join
The inner join joins the columns of every selected line on the left- hand side with the columns of all lines on the right-hand side that jointly fulfil the join_cond condition. A line in the resulting set is created for every such line on the right-hand side. The content of the column on the left-hand side may be duplicated in this case. If none of the lines on the right-hand side fulfils the join_cond condition, no line is created in the resulting set.
Resulting set for outer join
The outer join basically creates the same resulting set as the inner join, with the difference that at least one line is created in the resulting set for every selected line on the left-hand side, even if no line on the right-hand side fulfils the join_cond condition. The columns on the right-hand side that do not fulfil the join_cond condition are filled with null values.
Note
If the same column name occurs in several database tables in a join expression, they have to be identified in all remaining additions of the SELECT statement by using the column selector ~.
Example
Join the columns carrname, connid, fldate of the database tables scarr, spfli and sflight by means of two inner joins. A list is created of the flights from p_cityfr to p_cityto. Alternative names are used for every table.
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
fldate TYPE sflight-fldate,
carrname TYPE scarr-carrname,
connid TYPE spfli-connid,
END OF wa.
DATA itab LIKE SORTED TABLE OF wa
WITH UNIQUE KEY fldate carrname connid.
SELECT ccarrname pconnid f~fldate
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( scarr AS c
INNER JOIN spfli AS p ON pcarrid = ccarrid
AND p~cityfrom = p_cityfr
AND p~cityto = p_cityto )
INNER JOIN sflight AS f ON fcarrid = pcarrid
AND fconnid = pconnid ).
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
Example
Join the columns carrid, carrname and connid of the database tables scarr and spfli using an outer join. The column connid is set to the null value for all flights that do not fly from p_cityfr. This null value is then converted to the appropriate initial value when it is transferred to the assigned data object. The LOOP returns all airlines that do not fly from p_cityfr.
PARAMETERS p_cityfr TYPE spfli-cityfrom.
DATA: BEGIN OF wa,
carrid TYPE scarr-carrid,
carrname TYPE scarr-carrname,
connid TYPE spfli-connid,
END OF wa,
itab LIKE SORTED TABLE OF wa
WITH NON-UNIQUE KEY carrid.
SELECT scarrid scarrname p~connid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM scarr AS s
LEFT OUTER JOIN spfli AS p ON scarrid = pcarrid
AND p~cityfrom = p_cityfr.
LOOP AT itab INTO wa.
IF wa-connid = '0000'.
WRITE: / wa-carrid, wa-carrname.
ENDIF.
ENDLOOP.

Compare two tables and log the difference

Hi,
I want to compare two tables and log the difference in new table with the fields as (old value,new value, column name). The column name should be the changes value column

Can you show an example?
SELECT Foo.*, Bar.*
FROM Foo
FULL OUTER JOIN
Bar
ON Foo.c1 = Bar.c1
AND Foo.c2 = Bar.c2
AND Foo.cn = Bar.cn
WHERE Foo.key IS NULL
OR Bar.key IS NULL;

If I want to join two table together .
I want to search the number of record in IMEI that have N_SIM_STATE =1 in RCA_SMART_CARD .
The MSISDN in IMEI is equal to C_SIM_MSISDN in RCA_SMART_CARD .
How can I do and what is the sql statment ??
Please advice .

First you need to decide, from where you want to execute the query.
Let us assume it is instance A(as per your example).
Then what you need to do is:
1.     Create database link to instance B
*[url http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm]Here* is the semantics.
2.     After creating the database link to instance B, you can achieve the result set by running the below query:
        SQL> select count(*) from IMEI t1 join RCA_SMART_CARD@<db_link_name> t2 on t1.MSISDN = t2.C_SIM_MSISDN where t2.N_SIM_STATE = 1
        Hope it helps!

Select Oracletbl and tbl2, right click on them open physical diagram, selected objects. In the physical diagram page Create a join between Oracletbl and tbl2 with the condition code=code.
In business model create a complex join between these two. Now reload metadata/restart services check output.
Let me know if this does not work you.

Error joining two tables in graph pane

While trying to join two tables by draging one column onto a column of another table in a graph pane, an error dialog with the following message appears:
"Drag and drop failed. Please drag a column from one table in the graph onto a column of another table in the graph pane. If you are trying to create a self join, please create another instance of the table and adding same table to the graph pane."
How do join two tables in the query editor graphically?

I also have the same problem. I use MySQL. I do not have any foreign keys in my tables. If I try to create table joins graphically myself I get the following error:
"Drag and drop failed. Please drag a column from one table in the graph onto a column of another table in the graph pane. If you are trying to create a self join, please create another instance of the table and adding same table to the graph pane."
When I type SQL query(similar to the following) in the in the query editor it dosent work: (As a result same row is appearing more than one time when I test the application)
WHERE login.USERNAME=me.NAME
In the above Mayagiri suggested a turorial using Pointbase and tables with foreign keys which is not directly connected with problem.(Beacuse it seems no problems in Pointbase tables with foreign keys)
Any further is very much appreciated. Thanks in advance.

Joining two tables in two different schema

Hi All,
I have a requirement to join two tables in two different schema. How to join these two tables in view object.
Many thanks in advance.
Regards
Kaushik Gopalakrishnan

1) If these tables are in one and same database instance, then you can join them by specifying the fully-qualified table names (inlcuding the schema name), for example:
SELECT ...
FROM schema_A.table1 T1, schema_B.table2 T2
WHERE T2.parent_code = T1.code
AND ...2) If the tables are in different database instances, then you can create a database link in one of the databases and access the table from the other database via the DB link, for example:
SELECT ...
FROM schema_A.table1 T1, schema_B.table2@mydblink T2
WHERE T2.parent_code = T1.code
AND ...3) If the tables are in different database instances and there is no option for DB links, then you cannot join the tables in an ADF ViewObject.

Using a view to join two tables

Thank you in advance for any advice you can lend.
I am using this code in my MySQL db to create a view.
select
    job.id as job_id,
    umr_cost_calculation.plant_name,
    max(umr_cost_calculation.id) as max_id
from
    job,
    umr_cost_calculation
where
    job.id = umr_cost_calculation.job_id
group by job.id , umr_cost_calculation.plant_name
I did this so I can join two tables and pull in the most current cost data for a specific plant. The report will, at times, show the wrong (older) data. I can re-run the report, filter to just the one job and see again the wrong data. When I add the max_id to the report, it display the id and updates the report with the correct data. It appears that the view was stale and by adding the ID to the report this fixed the issue.
1) Is this the best way to make this join? I don't see how Crystal supports a subquery to make a join (this is why I used the view).
2) If I leave the max_id on the report, will this force the view to always update?

Try:
Select
D1.EmpLoginID,
Count(D1.ID),
Count(D1.AlarmCode),
D1.EmpName,
D1.EmpAddress,
D2.Db2Count
FROM DB1.Data D1
LEFT JOIN (SELECT
empLoginID, Count(*) as Db2Count
FROM DB2.ALL_Database
WHERE site = 'Atlanta'
GROUP BY empLoginID
) D2
ON D1.EmpLoginID = D2.EmpLoginID
GROUP BY D1.empLoginID, D1.EmpName, D2.EmpAddress, D2.Db2Count
Order BY D1.empLoginID ASC
