How to join two columns between two tables with different column names

Hi
How i can join 2 columns with different names between the 2 tables.
Can any one please give solution for this.
Thanks
Manu

Hi,
basic understanding of joins:
If you want to join 2 tables there should be matching column w.r.t. data and it's data type. You need not to have same column names in both the tables...
so, find those columns which has got same values..

How to join two tables with no similar columns

Hi all,
I have two tables as follows:
Table T1 have Attributes as follows:
GLCODE,
BRANCH,
ITEM_NUMBER,
DEMAND_DATE,
QUANTITY,
SOURCE
Table T2 have Attributes as follows:
FORECAST_DATE
Now in SQL if run the following stattement iam getting out put.
SELECT GLCODE,BRANCH,ITEM_NUMBER,DEMAND_DATE,QUANTITY, SOURCE,(SELECT DISTINCT FORECAST_DATE FROM T2) FROM T1
The above SQL Statement giving correct results for me.
The same SQL Statement how can we implement in mapping level?

You have to specify an outer join, but how do you do that if there is no join to begin with? I would do the following (which I didn't test yet):
add an extra column (say C_JOIN) to the T2-ingroup of the join operator and fill it with from a constant operator with say value 1. Then use T2.C_JOIN (+) = 1 as the join condition.
If every record in T2 is guaranteed to have the same value, instead of using a deduplicator, which will read all records, sort them and deduplicate them, you can use a filter with filter condition ROWNUM < 2, which only will read one record.
I am facing almost the same problem but not entirely thou and I was wondering if you have an idea how to even start.
Problem:
I got this table:SQL> desc ita.tpis32_job_status

This the above table, i am looking for JOBID (a five digit number) like 25875.
What I want to do is add or append this five digit number to a string to find the corresponding table in dba_tables or all_tables. The only way I have try to do this is by writing PLSQL as you see from here:
Re: Use PLSQL to delete tables dynamically
When the select is writing properly, the result of the five digit number from JOBID and the string should look like the below result (job_(five digit_%).
My problem is there is no relationship between ALL_TABLES and the my own table (ita.tpis32_job_status). Any help will be appreciated.
TABLE_NAME
JOB_58871_OUTDATA
JOB_58868_TS
JOB_58868_OUTDATA
JOB_58867_TS
JOB_58867_CMDLBL_2
JOB_58867_OUTDATA

Joining two tables with different DB

Hi
We have 2 sources DB2 and Oracle.
In DB2 we have two tables which stores.

Tbl1.case_no=Tbl1.case_no.
Oracle tbl
Code     Code_desc
111     Very good

My requirement is to join the tbl2 with Oracle tbl. Based on the codes in DB2 table I should display the Code_desc in my reports. Like this
Case_no     Code     Code_desc
11112     111     Very good
11113     123     bad

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.

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!

there are no matching records.
Table : Sections &Table : orders
I am expecting the final output like I have mentioned below.
How can i write a JOIN. Note there are no matching records from both the tables.
Pls.This is a very urgent requirement.Regards

Join two table in different instance

Hi,
I have two table in different instance .
IMEI in instance A
RCA_SMART_CARD in instance B
Below is the desc table :

EXTRA_DATA VARCHAR2(100)
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!

Two tables with different filter values base on a analysis

Hi guys,
let assume that I have a analysis with columns : group_id and sales.
Based on it I would like to create two tables : table1 where group_id =1 and table2 where group_id = 2.
Is OBIEE capable of doing it?
Regards,
Slavi

Hi Slavi,
You can do that in single analysis, but you need to have the group_id column two times.
That is, bring group_id_1, group_id_2 (same column), sales
Now in table 1,
bring group_id_1, sales
Then in selection steps for group_id_1 -> Select Members -> Action choose keep only -> choose the filter value 1
This will filter the table 1 with group_id 1
In table2 bring group_id_2, sales
Then do the same step for group_id_2 with value 2.
now in same report you have two reports with different filter.
If you want you can keep the same column name for both group_id columns, I just kept group_id_1, group_id_2 for easy reference.

How to put two files with the same name into the same folder?

How can I put two files with the same name and the same extention into the same directory?
Is this even possible?
Thanks in advance.

Are you sure? I would be very surprised if that was the case.
How does the computer/filing system differentiate the files, if not by their names?
How do you tell the computer which one you want? (On the command line.)

How to combine two applications with different workspaces in APEX

Hi,
Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
Thanks in advance,

Hello Satya,
>> I am Satya …
Please take one more step to help us and update your forum handle to something friendlier than user123… Thanks.
>> Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
This is not a trivial task.
You didn’t mentioned if both workspaces sharing the same APEX instance, or they are on two different instances (machines). I believe the latter is a pre-condition to a success.
First you need to remember that importing an APEX component, like a single page, is possible only to the same application that it was exported from. This is still valid if you have the same workspace on two separate APEX instances – one is an import of the other (which makes it an identical copy). Still, the application ID must be the same, or you’ll get the following error: “This page was exported from a different application or from an application in different workspace. Page cannot be installed in this application.”
You can’t simply manipulating the export file, if the two workspaces are sharing the same APEX instance, as all workspaces on the same instance shares the same APEX metadata files, and you’ll receive a “unique constraint violated” error messages. That means you can’t import one application into the workspace of the other, even if you are using a different application ID.
As far as I can see, the only viable way of doing an application merge is to have two identical workspaces, on two separate APEX instances. The two applications should share the same application ID, although this parameter can be changed in the import file. You should export the page in one application – on the first instance – and import it into the other application – on the second instance.
You should also make sure that the exported page ID doesn’t exist on the target application, otherwise it will be replaced by the new imported page. Also, if the imported page include references to shared components that are not defined on the second application, it might also pose a problem.
As I said, this is not trivial. The benefits are mostly depend on the amount and complexity of the pages you want to merge. If they are not many, and simple, you should consider just re-creating them on the target application. If they are very complex, the merge might fail anyway.

Arie.

Create n tables with different number names

Hi guys, I work with SQL Server 2008 and OS Windows Server 2008 R2 64 bits. I have to create 10 tables with different names e.g. 'Image1', 'Image2', and so on. For this goal, I use a loop and concatenation. Here is the code:
DECLARE @i INT
DECLARE @v_table_n CHAR
SET @i=1
SET @v_table_n='Image'
WHILE (@i<=10)
BEGIN
    DECLARE @STR VARCHAR(100)
       SET @STR = 'CREATE TABLE SQL_DB_Filestream.dbo.Image1' + @v_table_n + CAST(@i AS VARCHAR(10)) + ' (
   [ID_RowFeatVec] INTEGER NOT NULL PRIMARY KEY,
       [CF1] FLOAT,
   [CF2] FLOAT,
       [CF3] FLOAT
       EXECUTE @STR
    SET @i = @i + 1;
END
GO
As a result, an error message appears:
"The name 'CREATE TABLE SQL_DB_Filestream.dbo.Image1I1 (
    [ID_RowFeatVec] INTEGER NOT NULL PRIMARY KEY' is not a valid identifier."
I have tried a lot of versions but it doesn't work.
What am I doing wrong?
Best wishes

1) An SQL Programmer would write ten CREATE TABLE statements. Are you old enough to know about Rube Goldberg? He was a cartoonist who invented inanely complex device for simple task!
2) Ten identical tables is a huge design flaw. It is so awful I want to use it in one of my books. Tables are sets. A set is completed whole, or as Cantor said “a many that is treated as a one” (it sounds cool in German or Esperanto).
3) We hate loops in SQL. This is a declarative language. I will bet you have no idea what that means.
What you want to do is mimic a magnetic tape file system from the 1950's. We used to put a label on the tapes based on the date or a sequence number. Not a completed whole.
