SELECTing records from two tables. Set Operators, CASE, DECODE, ...

Hi all,
I have two tables:
CRETE TABLE T1 (T1_COL1 NUMBER, T1_COL2 NUMBER)
CRETE TABLE T2 (T2_COL1 NUMBER, T2_COL2 NUMBER)
T1 may or may not have records. T2 always has records. There are two scenarios.
Scenario 1:
=======
SELECT * FROM T1 returns five rows, and SELECT * FROM T2 returns 10 rows.
Now I need the five rows from T1.
Scenario 2:
=======
SELECT * FROM T1 returns zero rows, and SELECT * FROM T2 returns 10 rows.
Now I need the 10 rows from T2.
In other words, if records present in T1, I need them all. If not, I need records from T2.
There are no common columns (for joins).
Now need a single query to achive this. I tried set operators, CASE and DECODE. But I'm unable to solve it.
Please help. Thanks in advance.

Yes, Justin. I'm sure that this is the way it's modelled. I also find it's tough and odd.Are you sure it's the right way for that data to be modeled? I understand that's the way it is being modeled, but a data model change may be the best option.
Is there any other way, which is simpler, without using RANK?That's the simplest option I can think of. You could also do something like
SELECT t1_col1, t1_col2
FROM (
    SELECT t1_col1, t1_col2, rownum rn
      FROM (
        SELECT t1_col1, t1_col2
          FROM (
            SELECT t1_col1, t1_col2, 1 tbl
              FROM t1
            UNION ALL
            SELECT t2_col2, t2_col2, 2 tbl
              FROM t2
         ORDER BY tbl
WHERE rn = 1I'm not sure that's any simpler...

Can i select Records from two tables into an itab.

Hi,
    Suppose that i have two tables spfli and sflight.
    Now i want the records from both the tables into a single internal table.
    If so please let me know how this can be done.
    itab should consist of all the columns in sflight and spfli.
Regards,
Sai

Sai,
Yes u can do it using JOINs.
Use this link for ref
http://www.sap-img.com/abap/inner-joins.htm
INNER JOIN results are an intersection of the tables being joined where in only if both the tables havethe data the result is pused onto the result set.
WHERE as in LEFT OUTR JOIN you can push the data of the LEF T table on the resultset even when the join condition is not met.
The use is that you wantto have all the data that is there in left table and also the right table if the join condition is a success then right table fileds will have data else they are initial.
OUTJOIN's are used in MAINTENANNCE VIEWS, HELP VIEWS .
INNER JOINS are used DATABSE VIEWS.
Inner Join:-
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
INNER JOIN sflight AS f ON pcarrid = fcarrid AND
pconnid = fconnid )
INNER JOIN sbook AS b ON bcarrid = fcarrid AND
bconnid = fconnid AND
bfldate = ffldate )
WHERE p~cityfrom = 'FRANKFURT' AND
p~cityto = 'NEW YORK' AND
fseatsmax > fseatsocc.
Left Outer Join
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 = 'FRANKFURT'.

Selecting data from two tables

I am trying to select data from two tables. The only problem that I am running into, is that i am only seeing results from my 'uploads' table. there is also a record in documents where user = 1 that should show up. here is my sql:
$userIDNum = 1;
$sql="Select *
from uploads, documents
WHERE uploads.user = documents.user AND uploads.user = $userIDNum
ORDER BY uploads.title ASC, documents.title ASC";

You'll need to explain a little more about your data and what you are trying to accomplish. Your current sql will select all columns from both the uploads and documents tables but only rows where the user id in both tables match, AND the user id equals 1. Is that not what you are seeing? Where's the code that outputs the results?

Selecting columns from two table is slow but same

I am selecting 27 columns from two tables
which running for more than 30 minutes. but
if I select count(*) with the same query
except the columns it is coming in seconds.
Where is the error?

If you post
1) The table definitions for the underlying tables
2) The indexes that are on the tables
3) The two SQL statements you're running
4) The explain plan for both statements
we can probably be of some assistance.
My guess is that the count(*) is able to return much more quickly because the optimizer is able to use a significantly faster query plan that is based on an index which the longer-running query cannot utilize. Without the information I've requested, though, it's hard to do more than speculate.

How to pass selected records from one table to another ?

Hi,
In my view i have designed a table with certain records. I need to pass only specific records of this table to another table which been designed in another view. Can anybody please give sum idea for this.
Rgds
Sudhanshu

hi,
Refer the below code:
1. I have selected some data from the table.
2. The selected data is moved to some other internal table.
3. Internal table is further binded to the node in which data is to be shown.
data : lo_nd type ref to if_wd_context_node,
lo_nd1 type ref to if_wd_context_node,
lt_temp type wdr_context_element_set,
wa_temp type ref to if_wd_context_element,
ls_node1 type sflight,
lt_node1 type STANDARD TABLE OF sflight.
lo_nd = wd_context->get_child_node('CN_MAIN'). <CN_MAIN is my node>
CALL METHOD lo_nd->get_selected_elements <here selected data is moved to lt_temp>
 RECEIVING
 set = lt_temp.
loop at lt_temp INTO wa_temp.
 CALL METHOD wa_temp->get_static_attributes
 IMPORTING
 static_attributes = ls_node1. <Selected data in work area.>
 APPEND ls_node1 TO lt_node1. < Data moved to internal Table>
 CLEAR ls_node1.
ENDLOOP.
Finally Internal table is binded to the node required.
lo_nd1 = wd_context->get_child_node('CN_MAIN2').
lo_nd1->bind_table( lt_node1 ).
In your case , map this CN_MAIN2 with the Component Controller and from component controller you can access data in your second view also.
I hope it helps.
Thanx.
Saurav.

Records from two tables in different DB's

I have two tables (in different DB's) that I need to build
results from. I want to return results from all records in table A
and when a matching record in table B is found, retrieve the value
of a sqlbit field. The catch is that there may or may not be any
records in Table B that match Table A, and there may be more than
one record in Table B, but always only one record for Table A.
Table A is [Order] (yes I know, a reserved word - not my
design) and Table B is tblOrderFollowup - here is my current SQL
statement:
****************BEGIN SQL*************************
SELECT o.StoreID AS xStore
, o.Time AS dCreated
, o.ID AS xPurchase
, c.FirstName AS sFirstName
, c.LastName AS sLastName
, c.Company AS sCompany
, c.ID AS xCustomer
, o.Type AS xType
, o.Closed AS bClosed
, o.Tax AS nTax
, fu.OrderID AS xFUOrder
, fu.bComplete AS xFUComplete
FROM [Order] o
INNER JOIN Customer c
ON o.CustomerID = c.ID
AND o.StoreID = c.StoreID
LEFT OUTER JOIN db2.dbo.tblOrderFollowup fu
ON o.ID = fu.OrderID
AND o.StoreID = fu.StoreID
WHERE o.StoreID IN ( #allowableStoreIDs# )
AND o.StoreID = <cfqueryparam cfsqltype="cf_sql_integer"
value="#FORM.StoreID#" />
AND o.Time >= <cfqueryparam
cfsqltype="cf_sql_timestamp"
value="#CreateODBCDateTime(StartOfDay(FORM.dFrom))#" />
AND o.Time <= <cfqueryparam
cfsqltype="cf_sql_timestamp"
value="#CreateODBCDateTime(EndOfDay(FORM.dTo))#" />
AND o.Closed = <cfqueryparam cfsqltype="cf_sql_bit"
value="1" />
ORDER BY o.Time DESC
***********END SQL**********************
The problem here is that when I have more than 1 record per
OrderID/StoreID pair in Table B, I get more than one result - I
only want one. I am guessing I need a sub query, but don't know how
to go about doing that at all ...

You say you want only one result. Do you know which one you
want?
By the way, your query is probably not giving you the right
answer. My experience is that if you do this:
select stuff
from table1 left join table2 on something
where table2.somefield = somevalue
you get the wrong answer. What I do instead is,
select stuff
from table1 left join
(select stuff from table2
where whatever) need_an_alias on somthing

Find matching records from two tables, useing three key fields, then replace two fields in table1 from table2

I have two tables - table1 and table2 - that have the exact same schema. There are three fields that can be used to compare the data of the two tables, field1, field2, and field3. When there are matching rows in the two tables (table1.field1/2/3 = table2.field1/2/3)
I want to replace table1.field4 with table2.field4 and replace table1.field5 with table2.field5.
I have worked with the query but have come up with goobly goop. I would appreciate any help. Thanks.

If your field1, field2, and field3 combinations in these tables are unique, you
can do a join on them.
Select t1.field4, t2.field4 , t1.field5, t2.field5
from table1 t1 inner join table2 t2 on t1.field1 =t2.field1 and t1.field2=t2.field2 AND t1.field3=t2.field3
--You can update your table1 with following code:
Merge table1 t1
using table2 t2 on
on t1.field1 =t2.field1 and t1.field2=t2.field2 AND t3.field3=t2.field3
When matched then
Update Set
t1.field4= t2.field4
,t1.field5 = t2.field5 ;

Selecting Records from one table where records don't exist in a linked table

CA Forum: Crystal Reports
Tables:
Stock (Main Table)
Transactions (Left Outer Join)
Criteria:
Select all items with no transactions between a selected date range.
The items will exist in Main table but I want to select all items that haven't been in a transaction between a date range so I can identify no movement with stock items just sitting in the database doing nothing.
Any suggestions??

Sorry for the delay. Dam meetings all day yesterday.You are essentially looking for something that doesn't exist in the db so you need to look at it from a different approach.You definitely don't want to use a full outer join. From what i can tell from your description above you are looking for stocks that are inactive/idle.So you need not look at data that doesn't exist but the last activity date.So you'd want something along the lines ofselect s.stock_name, s.stock_blah, max(t.transaction_date) Transaction_datefrom stocks sjoin transactions t on s.itemid = t.itemidwhere whatever restrictions you need to addgroup by s.stock_name, s.stock_blahthis will produce one record for each stock you have in the stock table showing you only the last date of activityput that in a command in crystalin the selection expert in crystal reports put in a simple criteriatransaction_date <= some datethis will only pull in records based on your date selection so if you say give me all records from dec 31, 2006 you will know all the records being pulled in are stocks that have been idle since dec 31, 2006 or earlierlet me know if this doesn't work

Select record from database table

how to select a record from data-base table for current month in module-pool, i.e if current month is august then records selected should between 1/08/10 to 31/08/10.
And, i also want to select records for last month i.e if current month is august then records selected should be between 1/07/10 to 31/07/10.
And one thing more, it should work for every scenario. Like for months are changing then it should work according to that.
Example: If month changes to October then current month ll be October and last month ll become September.

Hi Nishant,
You can use the option ORDER BY in your SELECT clause.

Sorts the selected lines in ascending order by the primary key of the database table. This variant is only permitted for SELECT * ....
Notes
Since views do not have a primary key, specifying ORDER BY PRIMARY KEY only makes sense with database tables. If, however, you do specify ORDER BY PRIMARY KEY with a view, all fields of the view are sorted in ascending order.
Variant 2
ORDER BY f1 ... fn
Effect
Sorts the selected records in ascending order by the specified column references f1 ... fn. If a list is also specified in the SELECT clause, the column references f1, ..., fn must appear in this list.
By supplementing the statement with DESCENDING, you can sort in descending order using any of the fields f1, ..., fn.
The default sort sequence is ascending order, but you can make this explicit by adding the addition ASCENDING.
Consider this code this will select the latest 10 records form DB table(Note can use Variant 2 for DB tables also.
REPORT zarun_1.
DATA : it_mara TYPE STANDARD TABLE OF mara WITH HEADER LINE.

 ORDER BY matnr DESCENDING. "Specify the Key Fields here.
LOOP AT it_mara.

ENDLOOP.

How do I extract matching records from two tables?

I'm trying to extract client records from our client database to put together a very targeted email campaign. As an example, the result I want is a list of names and email addresses of those clients who have a record in our system, have not had a visit in our clinic in the last year, and live within 200 miles of our clinic. I can capture the first two criteria in one extract, and the second in another. I can then import those as tab delimited data into Numbers. What I then need to do is create a third table that represents ONLY those records that exist in both tables.
Can someone tell me if this is possible and if so, how to do it?
I'd be very appreciative of any help, thank you.

You can create a column that generates a serial marker on the table from which you want to transfer the data, making all the names that also appear on the other table. Not that the formula will mark only exact matches.
Here's a short example:
Table 1 on the left, is one of the two tables imported from the tab delimited data files. It has other data, but only the names in column A are used to identify records appearing on both tables.
Table 2 on the right, contains the names and other data (represented by the email addresses in column B), to be transferred to the third table.
Column C of this table contains the formula that counts off the rows containing names appearing on both tables. The version below is in C2, and is filled down to the end of the column.
=IF(COUNTIF(Table 1 :: $B,A2)>0,MAX($C$1:C1)+1,"")
Note that jane Doe is not counted (or transferred) as her name is recorded differently on the two tables.
Table 3 is the results table. It contains one formula for each column to be transferred from Table 2 to Table 3.
A2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $A))
B2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $B))

EDIT: I was working in Numbers '09 when developing this, and got the following warning when I saved a copy as an iWork '08 document:
Referencing row or column ranges that include header or footer cells isn't supported. The formula references were updated to exclude header and footer cells.
The formulas in Table 2::C2 references C1. You may have to ensure that Table 2 does not include a header row.
B.
EDIT2: A check on the file in Numbers '08 showed no apparent change to the formula, and editing Jane Doe's name on table 1 resulted in her name being added to Table 3.

Hi Tulacenath
So your invoice table does not have a reference to the customers (companys) that the invoices belong to?
