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

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

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.

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.

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.

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.

Parent-Child Join on tables in Database Adapter

Hi,
We are doing a join on two tables(T1 and T2) in Database adapter for an Insert operation. There is no Reference Integrity between these two tables in Database, but join is done through bpel database adapter.
Here is a scenario - when we try to insert a record(parent-child), into these two tables, If there is any data issue in any of the child record, Adapter inserts parent-record, also inserts few child-records it processed before it encountered this data issue and terminates.
Issue here is , We want this to be transactional, it means, If any of the child record fails adapter should rollback the entire insert operation both from parent and child tables and exit with an error. Instead BPEL inserting half records into child table.
Is there any parameter I need to set or am I missing anything? Someone please suggest.
Thanks,
Phani

There are a few options I guess.
1. Add the referential key constraint.
2. Add custom logic in your BPEL project to compensate for any errors you encounter in your BPEL processes.

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!

Join two tables TPAR, TVPG

Dear Gurus,
I am a functional Consultant and do not know the ABAP.
I want to know that is there any way to join two tables (TPAR, TVPG) and extract the filed PARGR from table "TVPG" and field ERNAM from Table "TPAR" into a third table.
Wishes
Abhishek

Hi,
it´s complicated, because you must identify what you whant to relacionated....
view... V_TPAR you can see up level partner function...
is the best i can do.sorry.
but if you identify the element between the two tables, you can do a Z* view.
reguards,
Miguel
If this message help you , dont forget to give point´s. thanks

Join two table (Inner Join)

how to join two tables using inner join.

Tariq,
Pretty vague question. You can create joins in an ABAP program, or while creating a view, or when creating a SAP query of one type or another. Some people download tables and then join them using desktop software. If you can elaborate your question I may be able to give you a better answer.
I recently joined two wooden tables at a picnic. I used 24 gauge galvanized wire combined with duct tape, so I guess you couldn't really call that an 'inner join'.

Join Two tables in UI So that it look like one table.

Can anyone provide me how to join table in viewing..
Rite now i am reteiving fields in one table and other field in another table. But while viewing i want to join on UI.
I am getting gap between these 2 tables.
How to do that?
Thanks

Hi Nitin,
why you want to join two tables.? if you want to display the data from more then one data source (Node ) then you can use table variant in that case. See the following Links for reference hope it will help.

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.

How do you join two tables from different Oracle schemas using a subquery

I am trying to join two tables from different Oracle schemas using a subquery. I can extract data from each of the tables without a problem. However, when I combine the select statements using a subquery I get the Oracle error *'ORA-00936: missing expression'*. Since each SELECT statement executes on its own without error I don't understand what is missing. The result set I am trying to get is to match up the LINE_ID from PDTABLE_12_1 in schema DD_12809 with the MAT_DESCRIPTION from table PDTABLE_201 in schema RA_12809.
The query is as follows:
sql = "SELECT [DD_12809].[PDTABLE_12_1].LINE_ID FROM [DD_12809].[PDTABLE_12_1] JOIN " _
+ "(SELECT [RA_12809].[PDTABLE_201].MAT_DESCRIPTION " _
+ "FROM [RA_12809].[PDTABLE_201]) AS FAB " _
+ "ON [DD_12809].[PDTABLE_12_1].PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS"
The format of the query is copied from a SQL programming manual.
I also tried executing the query using a straight JOIN on the two tables but got the same results. Any insight would be helpful. Thanks!
Edited by: user11338343 on Oct 19, 2009 6:55 AM

I believe you are receiving the error because you are trying to JOIN on a column that doesn't exist. For example you are trying to join on FAB.PIPING_MATER_CLASS but that column does not exist in the subquery.
If you want to do a straight join without a subquery you could do the following
SELECT DD_12809.PDTABLE_12_1.LINE_ID
,       FAB.MAT_DESCRIPTION
FROM    DD_12809.PDTABLE_12_1
JOIN    RA_12809.PDTABLE_201    AS FAB ON DD_12809.PDTABLE_12_1.PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS HTH!

Joining two tables in PL/SQL

Hi there,
I have two problems...first being:
We are trying to run a sub-query within a WHERE/AND clause. I am not sure on the correct syntax on how to run the sub-query as denoted in the code below. Secondly I am trying to join two tables with a common column name (ie: CIPIDI_NR). Considering I cant fix the first problem I cant test out the sub-query. So any help on either would be grateful. Cheers
Select *
from TBL_CIPIDI
     WHERE CIPIDI_NR like nvl ('in_case_number%', CIPIDI_NR)
AND CIPIDI_NAME like nvl ('in_case_name%', CIPIDI_NAME)
AND COST_CENTRE LIKE NVL ('in_cost_centre%', COST_CENTRE)
AND CIPIDI_DESCRIPTION like nvl ('in_description%', CIPIDI_DESCRIPTION)
AND CLAIMANT_NAME LIKE NVL ('in_claimant%', CLAIMANT_NAME)
AND REQUESTOR LIKE NVL ('in_requestor%', REQUESTOR)
AND PROJECT_MANAGER LIKE NVL ('in_project_manager%', PROJECT_MANAGER)
AND TEAM_LEADER LIKE NVL ('in_team_leader%', TEAM_LEADER)
     AND ********RUN THE QUERY BELOW************
SELECT C1.CIPIDI_NR, C2.CIPIDI_NR
from TBL_TEAM_MEMBERS C1, TBL_CIPIDI C2
     WHERE C1.CIPIDI_NR = C2.CIPIDI_NR
     AND TEAM_MEM_NAME LIKE NVL ('in_team_mem_name%', TEAM_MEM_NAME)
);

You really need to start providing create table and insert statements for tables and sample data for testing, the results that you want based on that data in order to clarify the problem, your Oracle version, and a copy and paste of an attempted run of your code, complete with any error messages received. The following is my best guess at what you might be looking for.
Select *
from   TBL_TEAM_MEMBERS C1, TBL_CIPIDI C2
WHERE C1.CIPIDI_NR = C2.CIPIDI_NR
AND    c1.CIPIDI_NR          like nvl (in_case_number     || '%', c1.CIPIDI_NR)
AND    c1.CIPIDI_NAME        like nvl (in_case_name       || '%', c1.CIPIDI_NAME)
AND    c1.COST_CENTRE        LIKE NVL (in_cost_centre     || '%', c1.COST_CENTRE)
AND    c1.CIPIDI_DESCRIPTION like nvl (in_description     || '%', c1.CIPIDI_DESCRIPTION)
AND    c1.CLAIMANT_NAME      LIKE NVL (in_claimant        || '%', c1.CLAIMANT_NAME)
AND    c1.REQUESTOR          LIKE NVL (in_requestor       || '%', c1.REQUESTOR)
AND    c1.PROJECT_MANAGER    LIKE NVL (in_project_manager || '%', c1.PROJECT_MANAGER)
AND    c1.TEAM_LEADER        LIKE NVL (in_team_leader     || '%', c1.TEAM_LEADER)
AND    TEAM_MEM_NAME         LIKE NVL (in_team_mem_name   || '%', TEAM_MEM_NAME);
