SQL query to get last 10 records in the table?

Hi,
Can anyone tell me the SQL query to get last 10 records in the table?
Thanks!!
MCP

Please, define what "last" means. Sets are unordered by definition, so if you want to retrieve rows from a table in a specific order you need to specify what that order is - e.g. by maintaining a value in a column (or a combination of columns) that you can use in the ORDER BY clause of the SELECT statement.
If, for instance, you kept the time when the row was inserted in a special column (InsertedTime), you could use this in your query like this:
select top (10)
<column list>
from <table or view>
where <restriction(s)>
order by InsertedTime desc;

How to fetch last record from the table to display in screen painter?

Hi Gurus,
              I have a requirement where i have to fetch the last record value in the table.
I have a screen where the TEXT name is REQUEST and I/P field name is REQ and SAVE push button.
In this I/P field automatically 1 should display when i excecute the program and when i save this, the request number should turn to 2 that is dynamically..once agin save then 3 and so on....and this 1, 2, 3 will be storeing in table.
I have succeeded till generating the values dynamically and saving in the table like 1 is displayed and when i click save it is changeing to 2..but the problem is when i am coming out of program and logon again the request number is again displaying as 1 rather it has to start with 4 because already 3 request are there in the table.
My code is...
Table zsave.
data declarations....
data req type i.
req = 0.
req = zsave-req.
PROCESS BEFORE OUTPUT
req = 0.
select req into table fun_st from zsave.
req = zsave-req.
zsave-req = req.
req = zsave-req + 1.
PAI
req = zsave-req + 1.
zsave-req = req.
when 'save'.
wa_funst-req = zsave-req.
Please can you provide me with the solution....answer will be rewared.
THKS

Can you tell me, when updaing the ZSAVE table with the counter value are you modifying the exisiting value or inserting the value as new record?
From the code in your first post, i see that you are extracting records into internal table but when you are moving to variable REQ, you are moving from table work area which is blank, so everytime when you execute it may be starting as 0.
Hope below code can help you understand on handling your requirement
Global Declaration:
>DATA: l_req TYPE i.
PBO:
SELECT MAX( req ) INTO l_req FROM zsave.
l_req = l_req + 1.
PAI:
DATA: wa TYPE zsave.
CASE ucomm.
WHEN 'SAVE'.
    wa-req = l_req.
    INSERT zsave FROM wa.
ENDCASE.

How to get the only the last raw of the table

Hello All,
While fetching a table into internal table, how to get only the last record of the table.?
Thanks and Regards, Pradeep

I hope following code will solve your problem.
DATA : it_bseg TYPE TABLE OF bseg,
x_bseg TYPE bseg,
v_index TYPE i.
SELECT COUNT(*)
FROM bseg
INTO v_index.
SELECT *
FROM bseg
INTO TABLE it_bseg.
READ TABLE it_bseg INTO x_bseg INDEX V_INDEX.
First SELECT will give you the number of rows in a table in v_index. Second SELECT will fetch all table data and then READ will give you the last record of the table in a structure x_bseg.

How to get the last record from the database

I am using MS Access database and Swings as GUI. I want to get the last record of a particular column from the table and store it as a varaible.

Hi
To get Last record of resultset, you have pass some parameter in constructor of CreateStatement.In such case Resultset should be scrollable and Readonly
Example
objStatement=objCon.createStatement ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
mwwResultSet=cwwStatement.executeQuery(mwwSqlQuery);
while(mwwResultSet.next())
if(mwwResultSet.isLast())
//Fetch the required column record.
String abc=mwwResultSet.getString(1);
I think this will work. Try it.
bye

SQL query to get the Datetime 06 hours prior to the table Datetime value

Hi Experts,
I'm just trying to create a SQL query to get the Datetime which should be 06 hours prior to my Table column value(Executiontime),
Eg: my Executiontime(column) value is 07:00AM means, this query should fetch the detail of first VMName from table at 01:00AM,
SQL Table Name: TestTable
Columns: VMName(varchar),status(varchar) Executiontime(Datetime)
SQL Query : Select Top 1 VMName from
TestTable where convert(date,Exeutiontime)=convert(date,getdate()) and
status='0' and ExecutionTime > dateadd(hour,6,getdate())
Request someone to alter this Query to my requirement or give me the new one.
Regards,
Sundar
Sundar

Hi All,
Thanks for your Prompt response. I tried the below queries, but still I don't have any luck. Actually the queries are returning the value before the condition met (say when the time difference is more than 06 hours). I want the
query to return exactly @ 06 hour difference or less than 06 hours,
Query 01: Select Top 1 VMName from TestTable where
convert(date,Exeutiontime)=convert(date,getdate())
and status='0'
and ExecutionTime >
dateadd(hour,-6,getdate())
Query 02: Select
Top 1 VMName from TestTable where
status='0'
and ExecutionTime >
dateadd(hour,-6,getdate())
Query 03: Select
Top 1 VMName from TestTable where status='0'
and ExecutionTime >
dateadd(hour,-6,ExecutionTime)
Can someone point out the mistake please.
Regards,
Sundar

SQL query to get the list of approvals

Hi,
Could someone let me know the SQL query to get the list of all the pending approvals for a user in OIM 11g R2.
Thanks

There are a few ways to do this:
- The easiest would be to use a Relationship Query from the CMC. To do this, go to the Universes section on the CMC, right click on the relevant universe, select tools >> Check Relationships.
- Use Query Builder. You will need more than one query to pull the information you need. You could try something like the below (for Webi)
SELECT SI_NAME, SI_WEBI, SI_DATACONNECTION FROM CI_APPOBJECTS
WHERE SI_KIND = 'universe' and SI_NAME = 'Universe Name'
This will give you a list of Webi Reports by SI_ID.
You'll need another query to list Webi report names:
SELECT SI_NAME FROM CI_INFOOBJECTS WHERE SI_ID IN (SI_ID from query above)
- This is trivial via Auditing / the Activity universe. This of course will only return reports that have already run.
Best.

Sql query to get union of matching rows

I want to write a sql query that shows union f all the [Type] for each [Key] if [Key] has atleast one [Type] in common and for non matched [Key]s it will return the row as it is.
For example In the sql table below [Key] '1' and '2' has [Type] 'B' in common and [Key] '1' and '4' has [Type] 'A' in common. In this case [Key] '1', '2' and '4' are related so result will be union of [Type]s in [Key]s '1', '2' and '4' which are 'A', 'B', 'C'
and 'E' for each [Key]. And [Key] '3' has no [Type] in common so it will return itself.
Input:
declare @categories table ([Key] int, [Type] Char(1))
insert into @categories ([Key], [Type]) values (1, 'A')
insert into @categories ([Key], [Type]) values (1, 'B')
insert into @categories ([Key], [Type]) values (2, 'B')
insert into @categories ([Key], [Type]) values (2, 'C')
insert into @categories ([Key], [Type]) values (3, 'D')
insert into @categories ([Key], [Type]) values (4, 'E')
insert into @categories ([Key], [Type]) values (4, 'A')
insert into @categories ([Key], [Type]) values (5, 'F')
insert into @categories ([Key], [Type]) values (5, 'G')
insert into @categories ([Key], [Type]) values (6, 'G')
insert into @categories ([Key], [Type]) values (6, 'H')
Desired output:
Key Type
1 A
1 B
1 C
1 E
2 A
2 B
2 C
3 D
4 A
4 B
4 E
5 F
5 G
5 H
6 F
6 G
6 H


The data element names are wrong. KEY is a reserved word; “Categories" and "type" are called attribute properties in ISO-11179 rules. Matthias Kläy is right; this is a graph problem in disguise, but you can do it with set theory to get what are called
equivalence classes.
An edge in a graph has two nodes. Some authors allow a single node to count as a edge, but a better way is to put the same node on both ends of the edge. Here is the graph in a table with all the needed constraints. This is why you should post DDL and not be
so rude.
DROP TABLE Graph;
CREATE TABLE Graph
(edge INTEGER NOT NULL,
node_1 CHAR(1) NOT NULL,
node_2 CHAR(1) NOT NULL,
CHECK (node_1 <= node_2),
PRIMARY KEY (node_1, node_2));
Here is your data in the correct format.
INSERT INTO Graph
VALUES
(1, 'A', 'B'),
(2, 'B', 'C'),
(3, 'D', 'D'), -- orphan node
(4, 'A', 'E'),
(5, 'F', 'G'),
(6, 'G', 'H');
Now Google Warshall's Algorithm. It uses three nested loops and an adjacency array. This is very clean and fast in a procedural language. Not so much in SQL. Let us do this in steps:
WITH X1 (edge, node1_1, node1_2, node2_1, node2_2 )
AS
(SELECT CASE WHEN G1.edge <> G2.edge
THEN G1.edge ELSE G2.edge END,
G1.node_1, G1.node_2,
G2.node_1, G2.node_2
FROM Graph AS G1, Graph AS G2
WHERE G1.node_1 IN (G2.node_1, G2.node_2)
AND G1.edge <> G2.edge),
X2 (edge, node_1, node_2)
AS
(SELECT edge,
CASE WHEN node1_1 IN (node2_1, node2_2) THEN node1_2 ELSE node1_1 END,
CASE WHEN node2_1 IN (node1_1, node1_2) THEN node2_2 ELSE node2_1 END
FROM X1)
SELECT DISTINCT edge,
CASE WHEN node_1 < node_2 THEN node_1 ELSE node_2 END,
CASE WHEN node_2 < node_1 THEN node_1 ELSE node_2 END
FROM X2;
The X1 subquery gets the paths of length two. The X2 subquery removes the middle node and creates a new sorted edge. Insert these new rows into Graphs, if they are not there. Repeat the process until no more rows are added.
DROP TABLE Graph;
CREATE TABLE Graph
(edge INTEGER NOT NULL,
node_1 CHAR(1) NOT NULL,
node_2 CHAR(1) NOT NULL,
CHECK (node_1 <= node_2),
PRIMARY KEY (node_1, node_2));
INSERT INTO Graph
VALUES
(1, 'A', 'B'),
(2, 'B', 'C'),
(3, 'D', 'D'), -- orphan node
(4, 'A', 'E'),
(5, 'F', 'G'),
(6, 'G', 'H');
Here is the monster rolled up into a single statement.
INSERT INTO Graph
SELECT DISTINCT edge,
CASE WHEN node_1 < node_2 THEN node_1 ELSE node_2 END,
CASE WHEN node_2 < node_1 THEN node_1 ELSE node_2 END
FROM (SELECT edge,
CASE WHEN node1_1 IN (node2_1, node2_2) THEN node1_2 ELSE node1_1 END,
CASE WHEN node2_1 IN (node1_1, node1_2) THEN node2_2 ELSE node2_1 END
FROM
(SELECT CASE WHEN G1.edge < G2.edge
THEN G1.edge ELSE G2.edge END,
G1.node_1, G1.node_2,
G2.node_1, G2.node_2
FROM Graph AS G1, Graph AS G2
WHERE G1.node_1 IN (G2.node_1, G2.node_2)
AND G1.edge <> G2.edge) AS X1(edge,node1_1, node1_2, node2_1, node2_2) )
AS X2(edge, node_1, node_2)
EXCEPT
SELECT * FROM Graph;
SELECT * FROM Graph ORDER BY edge, node_1, node_2;

SQL query to get a list of relations between workitems

How can I create a SQL query to get a list of all problems with related changes? And all problems with related incidents?
I have tried to join the tables RelationshipTypeDim with ProblemDimKey and ChangeRequestDim, but the results are not correct.

The relationships in the data warehouse can be kind of tricky. The relationships are contained in the WorkItemRelatesToWorkItemFactvw table. This table lists the related items by their WorkItemDimKey, so you cannot reference directly from the ChangeRequestDimvw
or ProblemDimvw. You will need to reference the WorkItemDimvw to get the WorkItemDimKey for each entry.
The query below will get all of the related work items from the Change Request class. The way the joins work is ChangeRequestDimvw gets the list of change requests. Then inner joins WorkItemDimvw to get the WorkItemDimKey for each CR. Then inner joins WorkItemRelatesToWorkItemFactvw
to get all of the CRs with related work items. Then inner joins the WorkItemDimvw again to get the ID of the related work item.
Now the tricky part is it appears that these relationship are set based on which item that created the relationship. So you need to union a second query that reverse the relationship on the WorkItemRelatesToWorkItemFactvw.
This query should give you a good start on getting the related work items. You can filter it down from here if you only want to include problems.
SELECT C.ID, WIWI.ID
FROM dbo.ChangeRequestDimvw C
INNER JOIN dbo.WorkItemDimvw WI ON
WI.EntityDimKey = C.EntityDimKey
INNER JOIN dbo.WorkItemRelatesToWorkItemFactvw AS WIRWI ON
WIRWI.WorkItemDimKey = WI.WorkItemDimKey
INNER JOIN dbo.WorkItemDimvw AS WIWI ON
WIWI.WorkItemDimKey = WIRWI.WorkItemRelatesToWorkItem_WorkItemDimKey
union
SELECT C.ID, WIWI.ID
FROM dbo.ChangeRequestDimvw C
INNER JOIN dbo.WorkItemDimvw WI ON
WI.EntityDimKey = C.EntityDimKey
INNER JOIN dbo.WorkItemRelatesToWorkItemFactvw AS WIRWI ON
WIRWI.WorkItemRelatesToWorkItem_WorkItemDimKey = WI.WorkItemDimKey
INNER JOIN dbo.WorkItemDimvw AS WIWI ON
WIWI.WorkItemDimKey = WIRWI.WorkItemDimKey
Order by C.ID
