Joining two tables on two keys of differnt datat types

Hi,
I have two two tables,
create table table1( primkey1 double, name varchar(30))
create table table2( primkey2 varchar(40), name varchar(30))
Now I have to join these two table in RPD. I tried to join but i got an error.
plz tell me the way to join these two tables.
thank you,

Hi,
Please ask the Back End team to change the data type of any of one primary key column. Its always better if you do the change in the Back End

Dynamic SQL Joining between tables and Primary keys being configured within master tables

Team , Thanks for your help in advance !
I'm looking out to code a dynamic SQL which should refer Master tables for table names and Primary keys and then Join for insertion into target tables .
EG:
INSERT INTO HUB.dbo.lp_order
SELECT *
FROM del.dbo.lp_order t1
where not exists ( select *
from hub.dbo.lp_order tw
where t1.order_id = t2.order_id )
SET @rows = @@ROWCOUNT
PRINT 'Table: lp_order; Inserted Records: '+ Cast(@rows AS VARCHAR)
-- Please note Databse names are going to remain the same but table names and join conditions on keys
-- should vary for each table(s) being configured in master tables
Sample of Master configuration tables with table info and PK Info :
Table Info
Table_info_ID   Table_Name
1       lp_order
7       lp__transition_record
Table_PK_Info
Table_PK_Info_ID   Table_info_ID   PK_Column_Name
2               1   order_id
8               7   transition_record_id
There can be more than one join condition for each table
Thanks you !

Hi Rajkumar,
It is glad to hear that you figured the question out by yourself.
There's a flaw with your while loop in your sample code, just in case you hadn't noticed that, please see below.
--In this case, it goes to infinite loop
DECLARE @T TABLE(ID INT)
INSERT INTO @T VALUES(1),(3),(2)
DECLARE @ID INT
SELECT @ID = MIN(ID) FROM @T
WHILE @ID IS NOT NULL
PRINT @ID
SELECT @ID =ID FROM @T WHERE ID > @ID
So a cursor would be the appropriate option in your case, please reference below.
DECLARE @Table_Info TABLE
Table_info_ID INT,
Table_Name VARCHAR(99)
INSERT INTO @Table_Info VALUES(1,'lp_order'),(7,'lp__transition_record');
DECLARE @Table_PK_Info TABLE
Table_PK_Info_ID INT,
Table_info_ID INT,
PK_Column_Name VARCHAR(99)
INSERT INTO @Table_PK_Info VALUES(2,1,'order_id'),(8,7,'transition_record_id'),(3,1,'order_id2')
DECLARE @SQL NVarchar(MAX),
@ID INT,
@Table_Name VARCHAR(20),
@whereCondition VARCHAR(99)
DECLARE cur_Tabel_Info CURSOR
FOR SELECT Table_info_ID,Table_Name FROM @Table_Info
OPEN cur_Tabel_Info
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @whereCondition =ISNULL(@whereCondition+' AND ','') +'t1.'+PK_Column_Name+'='+'t2.'+PK_Column_Name FROM @Table_PK_Info WHERE Table_info_ID=@ID
SET @SQL = 'INSERT INTO hub.dbo.'+@Table_Name+'
SELECT * FROM del.dbo.'+@Table_Name+' AS T1
WHERE NOT EXISTS (
SELECT *
FROM hub.dbo.'+@Table_Name+' AS T2
WHERE '+@whereCondition+')'
SELECT @SQL
--EXEC(@SQL)
SET @whereCondition = NULL
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
END
Supposing you had noticed and fixed the flaw, your answer sharing is always welcome.
If you have any question, feel free to let me know.

Problem encountered when join two remote tables in a materialized view

I'm using oracle 9.2.0.6
1> I have two tables:
CREATE TABLE TEST
A VARCHAR2(100 BYTE),
C DATE
CREATE TABLE TEST1
A VARCHAR2(100 BYTE),
B TIMESTAMP
2>. I defined a prebuild table:
CREATE TABLE MV_TEST1
ID1 ROWID,
A VARCHAR2(100 BYTE),
ID2 ROWID,
B TIMESTAMP(6),
C DATE
3> I created mview logs:
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST
WITH ROWID
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST1
WITH ROWID
INCLUDING NEW VALUES;
4> when I create mview:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
test.rowid id1,
test.a,
test1.rowid id2,
test1.b,
cast(null as date) c
from test , test1
where test.a = test1.a(+);
It is created successfully.
5> problem:
when I use remote tables to do the same thing, say test and test1 are in another instance and are connected by a dbLink, I couldn't create the mview successfully:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
a.rowid id1,
a.a,
b.rowid id2,
b.b,
cast(null as date) c
from test@dbl a, test1@dbl b
where a.a = b.a(+);
when run above statement, I got:
ORA-12015: cannot create a fast refresh materialized view from a complex query
Any ideas? Or joining two table through a dblink for a mview is not allowed at all?
Thanks in advance.

No one has a clue?

Joining two fact tables with different dimensions into single logical table

Hi Gurus,
I try to accomplish in Oracle Business Intelligence 11.1.1.3.0:
F1 (D1, D2 and D3)
F2 (D1 and D2 and D4)
And we want to build a report F1 F2 D1 D2 D3 D4 to have data for:
F1 that match only for D1-D2-D3
and data for
F2 that match only D1-D2-D4
all that in one row, so D3 and D4 are not common dimensions.
I can only do:
F3 (D1, D2)
F4 (D1, D2 and D4)
And report
F3 F4 D1,D2,D4 (all that in one row, and only D4 is not a common dimension)
Here is the very good example how to accomplish the scenario 1
http://108obiee.blogspot.com/2009/08/joining-two-fact-tables-with-different.html
But looks like it does not work in 11.1.1.3.0
I get
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 14025] No fact table exists at the requested level of detail: [,,Clients,,Day,ROI,,,,EW_Names,,,,,,,,,,,,,,,,,]. (HY000)
I am sure I set up everything correctly as advised in the blog but it works with only one not a common dimension
Is it a bug in 11.1.1.3.0 or something?
Thanks,
Kate

Thanks for all your replies.
Actually, I've tried the solutions you guys mentioned. Generally speaking, the result should be displayed. However, my scenario is a little bit tricky.
table Y's figures are not the aggregation of table X for D dimension. Instead, table Y's figures include not only D dimension total, but also others (others do not mean A, B, C dimension). For example, table Y stores all food's figure, while table X stores only drink's figure. D dimension is only about drink's detail. In my scenario, other foods' figure is not provided.
So, even if I set D dimension to all/total for table X, table X's result is still not the same as table Y.
Indeed, table Y does not have a column key to join to D dimension's key. So, if I select D dimension and table Y's measures at the same time in BI Answer, result returns no data. Hence, I can't compare table X and table Y's results with selection of D dimension.
Is there any solution to solve this problem?

Can we join two totals tables in ABAP Query

Hey Gurus!
Can we join two totals tables in ABAP query.
I am tyring to join FAGFLEXT with internal orders totals table.
Thanks
S

Hi,
Report painter majorily operates around characteristics and key figures.
ABAP query comes even more handy. The advantage is -
1. You can link many tables
2. Create selection screen as you like to have
3. User friendly report creation
4. Logic can also be coded.
5. Authorization can be set
I have written a article in SDN, which gives you an idea as to how to go about using ABAP query. Have a look on this - [Article - Practical Usage of ABAP Query|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20f6b256-23be-2b10-8b93-cad83a617634]

How we relate two tables using foreign key(fk)?

hi to all,
what are the conditions has to follow to relate two tables.I.e.,
the two tables have same primary keys(pk). if we relate these two tables in one table the pk and fk will be the same then how that table in active.

Hi
To relate two tables..we have foreign key relationship.
In one table v have primary key and in the second table, the same key is foreign key for that table..
To relate two tables, we can use JOINS
If there is already a suitable foreign key between two tables used in the view, these tables can be linked with a join condition from this foreign key.
Create a view on tables TAB1 and TAB2. TAB1 is the primary table of the view. TAB2 is the secondary table of the view. TAB1 is the check table for TAB2. The foreign key fields are assigned to the check table fields as follows:
TAB1-FIELD_A assigned to TAB2-FIELD_1
TAB1-FIELD_A assigned to TAB2-FIELD_1
The join condition of the view generated from the foreign key is then:
CREATE VIEW ... AS SELECT ... WHERE TAB2-FIELD_1 = TAB1-FIELD_A AND TAB2-FIELD_2 = TAB1-FIELD_B.
Join conditions can also be copied from generic and constant foreign keys. If a constant is assigned to a field in the foreign key, it is also assigned to the field in the join condition. There is no join condition for a generic relationship in the foreign key.
The foreign key between tables TAB1 (check table) and TAB2 (foreign key table) is defined as follows:
TAB1-FIELD_A assigned to TAB2-FIELD_1
TAB1-FIELD_B generic
TAB1-FIELD_C assigned to constant C
The join condition for the view generated from the foreign key is in this case:
CREATE VIEW ... AS SELECT ... WHERE TAB2-FIELD_1 = TAB1-FIELD_A AND TAB2-FIELD_2 = C.
Hope it helps

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.

While joining two tables

Hi all,
Assume that someone needs to join two tables called PA0002 and PA0008 with keyword PERNR and
that person needs to read the data of PA0008 aedtm's max.
That is there are many records based on the aedtm and the user wants to read the last date update and wants to use this in join, not separately.
Any idea?
Thanks.

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.

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 18 tables -- one at a time or in two stages ?? best one..??

I have to join 18 tables,.. Is it best to join all 18 in a single shot or to go with
multi stages-- 9 tables in one stage and after that anotther 9 tables..
Please anyone give me a good suggestion on this with some reason...
Thanks in advance

If you can look at your query and recognise that it is trying to collect (say) two small result sets and then join the result sets, then it is actually a good idea to express the query in that fashion to Oracle.
Take for example a query that sums last week's profits for a supermarket by department using a 9 table query in about 2 minutes. A similar query reports the previous week's profits with a marginally different query in about two minutes. You write the two queries as inline views and join them to report the percentage change in profit by department - and the query takes 4 hours because Oracle has used "complex view merging" to turn your two 9-table queries into a single 18-table query.
In this case, a workaround is to use the /*+ no_merge */ hint. In outline, something like:
select     {columns}
from
     select /*+ no_merge */
          dept_no,
          etc.
     from     ...
     )     lw,
     select /*+ no_merge */
          dept_no,
          etc.
     from     ...
     )     pw
where
     pw.dept_no = lw.dept_no
;In less obvious cases you may still be able to find that you can break up a big query into a few smaller, logical sections, and use this technique to generate and join what are, in effect, intermediate results.
An alternative to the /*+ no_merge */ hint is to use subquery factoring to the same end. There's a more complex example of the method here: http://jonathanlewis.wordpress.com/2007/07/01/internet-sql/
In either case, avoid turning your 18-table query into 18 separate pieces and sticking them back together - it may make the optimizer do some very silly things. Karen Morton mentions an example of this on her blog: http://karenmorton.blogspot.com/2008/06/dont-do-work-you-dont-have-to-do.html

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

DataType conflict in the R/3 when joining two tables

Hi Experts,
I have created a view with two table in the R/3 side by joining two common fields,but one of the field is getting error with different data type, so could any one suggest me how to resolve this issue without changing type.
Thanks,

Hi
Actually I have to pull one of the field from one table and place in other table and create a generic data source on it,Can any one suggest me with any solution or exists to solve this issue.

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!

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!
