Join resuslt from different table

Continuing with my above post:
But if there are more then 1 rows in each table then there will be a problem so a common field (foreign key) will be required for proper results using join.
with table1 as (select 'AC11' col1, 'AC21' col2
                from dual
                union
                select 'AC111' col1, 'AC211' col2
                from dual),
table2 as (select 'BC11' col1, 'BC21' col2
                from dual
           union
           select 'BC111' col1, 'BC211' col2
                from dual)
                select table1.col1, table1.col2, table2.col1, table2.col2
                from table1, table2
COL1 COL2 COL1_ COL2_
AC11 AC21 BC11 BC21
AC11 AC21 BC111 BC211
AC111 AC211 BC11 BC21
AC111 AC211 BC111 BC211
4 rows selected.Instead of 2 the output will be 4 records as there is no JOIN condition.

How to join fields from different internal tables and display into one int

hai i have one doubt...
how to join fields from different internal tables and display into one internal table..
if anybody know the ans for this qus tell me......

hii
you can read data as per condition and then can join in one internal table using READ and APPEND statement..refer to following code.
SELECT bwkey                         " Valuation Area
         bukrs                         " Company Code
    FROM t001k
    INTO TABLE i_t001k
   WHERE bukrs IN s_bukrs.
IF sy-subrc EQ 0.
    SELECT bwkey                       " Valuation Area
           werks                       " Plant
      FROM t001w
      INTO TABLE i_t001w
       FOR ALL ENTRIES IN i_t001k

      LOOP AT i_output INTO wa_output.
        READ TABLE i_t001w INTO wa_t001w WITH KEY werks = wa_output-werks.
        READ TABLE i_t001k INTO wa_t001k WITH KEY bwkey = wa_t001w-bwkey.
        wa_output-bukrs = wa_t001k-bukrs.
        MODIFY i_output FROM wa_output.
        CLEAR wa_output.

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

How to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,
v_dstat LIKE marc-dstat,
END OF str_table,
i_table1 TYPE STANDARD TABLE OF str_table1.
DATA:
BEGIN OF str_table2,
v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.

Field selection from differant tables

hello all,
         i need to select differant fields from differant tables when i select common fields from both the tables, is it necessary that the common field need to be a primary key in both tables.
thanks in advance
seenu

HI,
    No its not required that the common field be part of the primary key in both tables only thing is you need to prefix the table name if the field names are same. But if you are using a INNER JOIN then there is no need to select both fields since you know the content of both fields will be same if JOIN is ON these fileds as well.

Report using Data from different tables

Hello,
I am trying to convert a Cobol batch program to Oracle 6i tabular report.
The data is fetched from many different tables and there are lots of processing(i.e, based on the value of a column from one table need additional processing from different tables) required to generate the desired columns in the final report.
I would like to know what is the best strategy to follow in Oracle Reports 6i. I heard that CREATE GLOBAL TEMPORARY TABLE is an option. ( or REF CURSOR ?) I do not know much about its usage. Can somebody guide me about this or any other better way to achieve the result.
Thank you in advance
Priya

Hello,
There are many, many options available to you, each of which has advantages and disadvantages. This is why it is difficult to answer "what is best?" without alot more details about your specific circumstances.
In general, you're going to be writing PL/SQL to do any conditional logic that cannot be expressed as pure SQL. It can executed in the database, or it can executed within Reports itself. And most reports developers do some of both.
As a general rule, you want to send only the data you need from the database to the report. This means you want to do as much filtering and aggregating of the data as is readily possible within the database. If this cannot be expressed as plain SQL queries, then you'll want to create a stored procedures to help do this work.
Generally, the PL/SQL you create for executing within the report should be focused on control of the formatting, such as controlling whether a field is visible, or controlling display attributes for conditional formatting.
But these are not hard and fast rules. In some cases, it is difficult to get all the stored procedures you might like installed into the database. Perhaps the dba is reluctant to let you install that many stored procedures. Perhaps there are restrictions when and how often updates can be made to stored procedures in a production database, which makes it difficult to incrementally adjust your reports based on user feedback. Or perhaps there are restrictions for how long queries are allowed to run.
So, Reports offers lots of options and features to let you do data manipulation operations from within the report data model.
In any case, Oracle does offer temporary table capabilities. You can populate a temp table by running stored procedures that do queries, calculations and aggregations. And you can define and initiate a dynamic query statement within the database and pass a handle to this query off to the report to execute (ref cursor).
From the reports side, you can have as many queries as you want in the data model, arranged in any hierarchy via links. You can parameterize and change the queries dynamically using bind variables and lexicals. And you can add calculations, aggregations, and filters.
Again, most people do data manipulation both in the database and in Reports, using the database for what it excels at, and Reports for what it excels at.
Hope this helps.

How to display multiple data from different table in one table? please help

Hi
I got sun java studio creator 2(the separate installation not the one in the net beans)....
My question is about displaying data that have been taken from the database.... I know how to display data in a table(just click on the table "bind data" )... but my question is that:
when i want to use a sql statement that taken the data from different table...
how can i display that data in the table(that will be shown in the web) ??? when i click bind data on the table i can only select one table i can't select more than one....
Note:
1) i'm using the rowset for displaying the data in the table, since the sql statement is depending on a condition(i.e. select a from b where c= ? )...
2) i mean by different table is that( i.e. select a from table1,table2 )..
thanks in advance...

I want display the details of emp table.. for that I am using this SQL statement.
select * from emp where mgr=nvl(:mgr,mgr);
when I give the input as 7698 it is displaying the corresponding records... and also when I won't give any input then it is displaying all the records except the mgr with null values.
1)I want to display all the records when I won't give any input including nulls
2)I want to display all the records who's mgr is null
Is there any way to incorporate to include all these in a single query..It's a little unclear what you're asking.
The following query always includes rows where mgr is NULL, and when the bind variable :mgr is NULL, it displays all rows:
SELECT *
FROM     emp
WHERE     LNNVL (mgr != :mgr)
;That is, when :mgr = 7698, it displays 6 rows, and when :mgr is NULL it displays 14 rows (assuming you're using the Oracle-supplied scott.emp table).
The following query includes rows where mgr is NULL only when the bind variable :mgr is NULL, in which case it displays all rows:
SELECT     *
FROM     emp
WHERE     :mgr     = mgr
OR      :mgr      IS NULL
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL it displays 14 rows.
The following query includes rows where mgr is NULL only when the bind variab;e :mgr is NULL, in which case it displays only the rows where mgr is NULL. That is, it treats NULL as a value:
SELECT     *
FROM     emp
WHERE     DECODE ( mgr
            , :mgr, 'OK'
            )     = 'OK'
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL, it displays 1 row.

Retriving of data from different tables

retriving of data from different tables depening of the primary key this key field is there in all tables if it is there in one v table it should continue to other tables otherwise it should get exit from that it should display information message or otherwise success message if it is there in all tables .

Im writing the concept, just check it.
SELECT * from kna1 into lt_kna1.
if sy-subrc eq 0.
selest * from lfa1 into lt_lfa1
for all entries in lt_kna1.
endif.

Retrieving Data from different Tables with same tuple name

Hi,
I am made the following query from different tables. A tuple "name" is appearing in some tables. So when I run the qiery in a Java class, it delivers the same result of c.name, bpl.name and p.name. The result of c.name is correct, but the other 2 names are overwritten. It works perfect in a postgreSql query tool. How can I correct it, plz?
SELECT c.ad_client_id, c.name, o.c_order_id, o.ref_order_id, bp.name, bpl.name, o.dateordered, o.datepromised, od.c_orderline_id,p.m_product_id,p.name, cur.iso_code, od.qtyordered

Hi,
create alias, if u have similar field names as below. Use the alias name (rs.getString("cname") and rs.getString("bpname") and so on ) to retrive data.
SELECT c.ad_client_id, c.name as cname, o.c_order_id, o.ref_order_id, bp.name as bpname, bpl.name as bplname, o.dateordered, o.datepromised, od.c_orderline_id,p.m_product_id,p.name as pname, cur.iso_code, od.qtyordered

TEXT ITEM from different table

When a TEXT ITEM from different table exists in the DATA BLOCK,
and when after EXECUTE_QUERY (in trigger POST_QUERY) we issue
the SELECT for filling the TEXT ITEM from different table, how
we can prevent FROM_STATUS and RECORD_STATUS to get the
value "CHANGED" (because othervise COMMIT is updating all the
records which are the result of EXECUTE_QUERY)?

Set the record status back to query in Post Query trigger:
SET_RECORD_PROPERTY(:SYSTEM.TRIGGER_RECORD, 'BLOCK_NAME', STATUS
, QUERY_STATUS);

Fetch data from different tables print them is assigned places

Hi Friends,
I have designed one SMART-Form (Receipt).
I need to fetch data from different tables and the data must be print in assigned places. Please help me how to achieve this requirement. Thanks for your help.
Best regards,
Manju.
Edited by: Alvaro Tejada Galindo on Feb 12, 2008 10:20 AM

U're right.
When it creates a smartform it needs to decide when the main data have to be extracted:
- or in driver program
- or in smartforms
The difference can be in the performance, because the program can select the data only once, the smartforms needs to extract them everytime it's called.
I prefer to use a complex structure for the smartform interface as so all data I need are in only one structure, the problem is the complex structure is harder to be managed.

How to Select Data from different Tables Using Linq

Hi,
I have two different tables, I just want to collect data from tables using Linq to SQL Queries.
The tables looks like This
ID Name ImageUrl
Other Table is
ID EmpID CheckInTime CheckOutTime
What I want to Collect data from CheckInTime and want to place it in a that is in a list view
Same thing I want to do it for CheckOutTime And One thing I want to tell is both tables are joined by a FK EmpID with ID.
What Are the suggestions for me
I have Used this code
var data = from emp in db.Employees
join chk in db.CheckInCheckOuts on emp.ID equals chk.EmpID
select new EmployeeCheckInOut
Name = emp.Name,
ImageUrl = emp.ImageUrl,
CheckIn = emp.CheckInCheckOuts,
CheckOut = emp.CheckInCheckOuts
Here the CheckInCheckOuts is another table, I don't how do I access fields of the Other table "CheckInCheckOuts"
Thank you
Ali

Mitja,
Kind of Tables, I don't Know but I can Tell you that these are Two table, first Table Have Data in It, Name, ImageUrl I have filled this table with names and ImageUrls And are string type.Other Table is for the CheckInTime And CheckOutTime of the employee.
What I need that when I click on the Image button it Should displays The Current Datetime into the label below the Image button.
So I have Problem accessing my CheckInCheckOut Table because I may not have Idea about.Did you understand what I need to do, if you have more question please ask to me.
Thanks

BLOBs from different tables on one report

Hi,
I think the declarative BLOB support enhancement in 3.1 is really great. I am running into a problem with a report that joins two tables that both have BLOB columns. I have a Letters table and a Response table. The Response table has a FK linkage to the Letters table with the Letters table being the referenced table. I have a report that joins the Letters & Response tables and provides download links for the BLOBs in both tables. However on the report, only one of the link works at a given point in time. Both the links work fine in isolation (if the other link is commented out in the query).
I am using the APEX_UTIL.GET_BLOB_FILE_SRC function to download the files. Has anyone tried using this function to download files from two different tables in a single report?
TIA,
Ramesh

Ramesh,
Is this application on apex.oracle.com by any chance? I just went to test there and am having all sorts of trouble with declarative display of BLOBs in a report but on our dev box, two works fine (except that the link for both is the default rather than what I selected).

Select from different tables based on value

Hi Forum,
I'm stuggling with a problem:
In a table, I have two columns, pref_type and pref_value. Column pref_type stores a number value that is linked to a preference type, whereas column pref_value stores the value of that preference.
Unfortunately, the data model is such that per preference type a different tables needs to be used, so for example, if
pref_type = 1, table to query is A, whereas if
pref_type = 2, table to query is B.
I now want to write a query that resolves the preferences, ie it should branch to the respective table based on pref_type and search for pref_value and deliver back a different column of that respective table.
My first approach was like that:
select decode (pref_value, 1, (select result from A where pref_value = ???),
2, (select result from B where pref_value = ???)
where the three ??? depict the problem I'm having, as Oracle doesn't allow me to have a harmonized subquery here.
How do I achieve this?
Thanks for any help,
J. Sieben

I believe this is what you are trying to get at:
SELECT DECODE(m.pref_type, 1, (SELECT result FROM a
                               WHERE a.pref_value = m.pref_value),
                           2, (SELECT result FROM b
                               WHERE b.pref_value = m.pref_value)
FROM my_table mAlthough, if the tables are large, that might be pretty slow. Better than an outer join, but one of those correlated queries is going to be run for each row in my_table. You could lso try something like:
SELECT m.pref_type, r.result
FROM my_table m,
     (SELECT 'A' tbl, pref_value, result
      FROM a
      UNION ALL
      SELECT 'B', pref_value, result
      FROM b) r
WHERE DECODE(m.pref_type, 1, 'A', 'B') = r.tbl and
      m.pref_value = r.pref_valueHTH
