Finding results from different tables
Hello,
I am makeing a query on 2 tables. It works. But I need to find out which result is coming from which table. e.g 1 table is having abc record and 2nd table is having xyz record. I need to find out that abc has come from 1 table and xyz has come from 2nd table. Is it possible? If yes, Please give me a sample code snippet.
Thanks
Well one way that I can think of other than duplicating every column is to add one additional column to your select such as a.table1 then only populate the a.table1 column if the data came from the first table (any dba can help you with that since it is database specific). Then you just check for a null in the column in the resultset and will know which table it came from (null = came from table 2, !null = came from table1). Does not matter what data you stick in there as long as it comes from a not null column you should be golden

Find duplicates from different tables
I need to write a sql query to find out in which table
holds the duplicate data.
Duplicate : AAA company should be present(mapped) only once with XXX Partner. If it is repeated then would be considered
as duplicate
Please help in writing this query
Table A
Table B
Table C
company Partners company Partners
company Partners
AAA XXX AAA
XXX
AAA XXX
BBB YYY BBB
YYY
BBB YYY
AAA XXXX (duplicate Data)
Expected o/p :
table A contains duplicate data , or Table B contains Duplicate Data ETc...Chelseasadhu, I do not think AAA is duplicating as the partners are different XXX and XXXX.
Could you please clarify how are you finding its a duplicate value? Just the Company duplicate is your criteria?
You may try something below:
create Table TableA(Company varchar(100), Partners varchar(100))
Insert into TableA Select 'AAA','XXX'
Insert into TableA Select 'BBB','XXX'
Insert into TableA Select 'AAA','XXXX'
create Table TableB(Company varchar(100), Partners varchar(100))
Insert into TableB Select 'AAA','XXX'
Insert into TableB Select 'BBB','XXX'
--Insert into TableB Select 'BBB','XXXCC'
create Table TableC(Company varchar(100), Partners varchar(100))
Insert into TableC Select 'AAA','XXX'
Insert into TableC Select 'BBB','XXX'
Declare @DuplicateTableA int =0,@DuplicateTableB int=0,@DuplicateTableC int=0
Set @DuplicateTableA=(Select Case when exists(Select COUNT(1) From TableA Group by Company having COUNT(1)>1) then 1 else 0 end)
Set @DuplicateTableB=(Select Case when exists(Select COUNT(1) From TableB Group by Company having COUNT(1)>1) then 1 else 0 end)
Set @DuplicateTableC=(Select Case when exists(Select COUNT(1) From TableC Group by Company having COUNT(1)>1) then 1 else 0 end)
/* Once you have the existence info, its easy for you to do the display at your application layer*/
Declare @DisplayText Varchar(MAX) =''
Set @DisplayText = (Select Case when @DuplicateTableA = 1 then 'TableA contains duplicate data' else '' end)
Set @DisplayText = @DisplayText+(Select Case when Len(@DisplayText)=0 then '' else ' ' End + Case when @DuplicateTableB = 1 then 'TableB contains duplicate data' else '' end)
Set @DisplayText = @DisplayText+(Select Case when Len(@DisplayText)=0 then '' else ' ' End + Case when @DuplicateTableC = 1 then 'TableC contains duplicate data' else '' end)
Select @DisplayText

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
PriyaHello,
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 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 SevalkarIf 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.

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.

and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.

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

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.

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); -
Getting Result from multiple table using code table.
I am having hard time getting data from different table not directly connected.
The data model is not proper. Why should you store the game details in separate tables?
IMO its just matter of putting them in same table with additional field gamename to indicate the game. That would have been much easier to query and retrieve results
Anyways in the current way what you can do is this
SELECT p.ID,p.Name,c.CategoryName AS [WinnerIn]
FROM GameParticipants p
INNER JOIN (SELECT ParticipantID, Value AS ParticipantName,'CGW Table' AS TableName
FROM CGWTable
UNION ALL
SELECT ParticipantID, Value AS ParticipantName,'FW Table' AS TableName
FROM FWTable
SELECT ParticipantID, Value AS ParticipantName,'WC Winner' AS TableName
FROM WCWinner
... all other winner tables
)v
ON v.ParticipantID = p.ID
AND v.ParticipantName = p.Name
INNER JOIN Category c
ON c.TableName = v.TableName
If you want you can also add a filter like
WHERE p.Name = @Name
to filter for particular player like Henry in your example

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...Hi,

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. -

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
seenuHI,
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.

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 AMU'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.

Find out from which table a ES gets his data
Hello,
I'm now asking myself (for a couple of hours) how I can find out from which table(s) a Enterprise Service gets his data. I don't find any hint about this on ES Workplace, sproxy or soamanager. Has anyone a usefull hint for me?Hi Marco,
This actually is an excellent question, as it allows to clearly realize, that ES Repository is only a modeling device and it does not contain any implementation details.
If you are interested in implementation details, then Services Registry and the respective backend system are your friends, as Enterprise Services are implemented in these backend systems and then published in the central phone book - the Services Registry.
If you haven't applied yet for the free access to the ES Workplace systems, do so as this will give you access to the SAP ERP discovery system that implements all the ECC related Enterprise Services.
Now, if you want to see the implementation details for a given service - start from the ES Workplace. Go to the Services Registry and find an ECC service of interest. Then, on the General tab of the service you will find the Namespace and Internal Name. Having these two values, log on to the ES Workplace ECC system, start transaction SE80 and select Enterprise Services Browser. If this option is not available, go to Menu -> Utilities -> Settings and select Enterprise Service Browser. Find the namespace and the service (by its internal name) then navigate to the implementing code - which typically is an ABAP Object interface and an implementing class.
The only reason I am referring to the ES Workplace Service Registry and its discovery system is, because it is a platform we all have access to. Each client builds their own SOA landscape, where only certain Enterprise Services are published in the Services Registry. And, of course, the system landscape can be more complex - containing not only ECC but other SAP Business Suite products.
I hope this helps a bit.

Andrzej
