How to retrieve last record entered into database
Hi all,
I want to retrieve the last resord entered into a database table.
I have a MS Access database.
This code does not return the last record but its my nearest attempt to.
Can anyone suggest the correct SQL or Solution.
Help is greatly appriciated.
Thanks.
String str = "SELECT * FROM Missions WHERE Mission = (SELECT MAX(Mission) FROM MISSIONS)";
ResultSet rs = null;
String f1 = null, f2 = null, f3 = null, f4 = null;
try{
rs = statement.executeQuery(str);
txtMissionInformation.setText("");
int row = 0;
while(rs.next()){
f1 = rs.getString(1);
f2 = rs.getString(2);
f3 = rs.getString(3);
f4 = rs.getString(4);
System.out.println(f1 + " " + f2 + " "+f3+" "+f4);
txtMissionInformation.append(f1 + ", "+ f2 + ""+","+f3+","+f4);
System.out.println("Query Complete !");
} catch(Exception e){
e.printStackTrace();
}
I fixed my problem, i aded an autonumber field to my database set it as primary key and called it ID. i then used the syntax from before and it worked.

Selecting the last record from a database table
In my ABAP Program, I have to use a select statement to retrieve the last record from the database table with the same key. In other words, the Program will get more than one hit on the database table for the selected keys and I need to retrieve values from only the last record and not the first. I know I can use an internal table to sort the records first and then retrieve the right value. But to make things easier, is there a SELECT statement keyword than I can use to do this in one single step? Thanks!
hi,
tables:mara.
data: begin of it_mara occurs 0,
matnr like mara-matnr,
meins like mara-meins,
mtart like mara-mtart,
end of it_mara.
select-options:s_matnr for mara-matnr.
select matnr
meins
mtart
from mara
into table it_mara
where matnr in s_matnr.
if not it_mara[] is initial.
sort it_mara by matnr descending.
read table it_mara index 1.
endif.
then you get the last record of the select statement.

suggestHi,
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.

Hi, all.
How do you get information entered into iCal and Contacts on an equipped iPhone to push to an equipped MacPro? So far it's been a one way street Macpro to phone, and that's not what I was told it would be. I've been through all settings on both devices and see no way to do this. Help! If I synch the old fashioned way, what's going to happen?First check that all your settings are correct, that contact syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the contacts you are adding are added to your 'iCloud' group and not an 'On My Mac', 'On My Phone' or other non iCloud group (you can do this by checking in groups), non iCloud contacts will not sync.
If you are sure that everything is set up correctly and your contacts are in the iCloud group, you might try unchecking contact syncing in the iCloud settings, restarting your device and then re-enabling contact syncing.
First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings. -

Formula to get last record entered for a specific code in a field
I work at an inpatient facility where our patients experience several movement actions -- transfers from unit to unit, Leaves, return from leaves, and change in commitment status. We collect all of these actions in one table. For our census report we use a subreport to show the list of patients who are on leave. The problem I am having is pulling the most current movement that was a leave if the last movement action code entered was a change in commitment status. We really should not have put the change in commitment in this table as it is not a movement. When a change in commitment occurs and the patient is on leave, they drop off my report because the last change was not a leave. We have to enter the leave again so it is the last record entered to fix.
The table contains these fields:
Doc_ID
Parent_ID
Folder_ID
Effective Date
From_Unit
To_Unit
Time_of_Change
Leave_status_Code
Move_Action_Code
Commit_Status_Code
The Move_Action_Code field contains these codes:
L = Leave
C = Change in Commitment Status
B = Return From Leave
I = Initial Admission
D = Discharge
R = Recommitment
V = Unit to unit transfer
A patient may have several leaves in the same admission (home visit, then back, etc.). I need a formula to show only most current leave if they haven't returned from leave and need to totally ignore any change in commitment status.
Thanks in advance to everyone for your help in this forum!Hi Jerri,
To identify a patient, I assume it would be Folder_ID. Create a group on this field. Also create a group on Effective Date.
Hide the Detail section and the Group Headers for both of these. You can also hide the Group Footer for Effective Date.
In the Group Footer for Folder_ID, drop in the Move_Action_Code and any other fields you want.
When you look at your report, this will show you the last Move_Action_Code for that patient.
If you can group your data properly, the Group header will always show the first record and the Group Footer will always show the last record.
Hope this helps,

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.

I am using the "fetch all" vi to do this, but it is retrieving one record at a time, (if you examine the block diagram) How can i retrieve all records in a faster more efficient manner?
If this isn't faster than your previous method, then I think you found the wrong example. If you have the Database Connectivity Toolkit installed, then go to the LabVIEW Help menu and select "Find Examples". It defaults to searching for tasks, so open the "Communicating with External Applications" and "Databases" and open the Read All Data. The List Column names just gives the correct header to the resulting table and is a fast operation. That's not what you are supposed to be looking at ... it's the DBTools Select All Data subVI that is the important one. If you open it and look at its diagram, you'll see that it uses a completely different set of ADO methods and properties to retrieve all the data.

How to retrieve the data from SAP database.
Hi Pals,
How to retrieve data from SAP R/3 System to my third party software. I will make my query little bit more clear. There is a list of assets entered and stored in the SAP system. For example 3 mobile phones.
1) Mobile 1- Nokia
2) Mobile 2 - Samsung
3) Mobile 3 u2013 Sony
Now think I do not know what all assets is there. I have to retrieve the data and get it on my third party software. Just display the list of assets. Lets say SAP XI is also there. Now how will I map it and get the details.
Please give me step by step method.
N.B: Just to read the data from SAP database.
Please make the flow clear step by step.
Thanking you
AKHi,
You can use RFC or ABAP Proxy to make synchronous call with SAP.
Under RFC or ABAP Proxy Program you can get the data from SAP tables. Direct access to SAP Database is not preferrable even if its possible.
The better way to go for RFC or PROXY.
You will send the request from Third party system and the it will be as input parameters from RFC/ Proxy it will response based on it.
This got it all..

How to select last record or first record value in a formula?
Post Author: d111
CA Forum: General
I am using a query in a report that in addition to other columns, has a column of month labels like:
There are no unique identifiers or sequence fields that can be used. There is only 4 columns: the label and 3 percent columns.
Jan07Feb07Mar07Apr07etc.
I would like to show the range of months I am using in a label on the report showing the last and first records value. like: "Jan07 to Jun07".
I can not see how to use the functions maximun or minimum since it sorts the months alphabetically.
I would like to use a formula to just grab the first and last record. I can't seem to find any information on this anywhere.
Please advise and thanks.Post Author: bettername
CA Forum: General
Hmm... I suspect what you actually want is the minimum and maximum dates in the report, rather than the first and last records (even if they do happen to come out in date order). So you need to convert the text dates to real ones, and then pick the min/max values.
If so, try these:
Formula "ConvertToDate" (for details section) which converts your text field into a real date - suppress it once placed!:
//Since you have 2-digit years, this conversion assumes that all your dates are >=year 2000
numbervar the_month;if left({YourTable.YourField},3) = "Jan" then the_month:=1 elseif left({YourTable.YourField},3) = "Feb" then the_month:=2 elseif left({YourTable.YourField},3) = "Mar" then the_month:=3 elseif left({YourTable.YourField},3) = "Apr" then the_month:=4 else
//...etc etc you fill in the rest!
if left({YourTable.YourField},3) = "Dec" then the_month:=12;
date(tonumber("20"+right({YourTable.YourField},2)), the_month, 1);
Formula "Show Date Range" (for anywhere on the report) to show the min/max values of the dates;
totext (minimum({@ConvertToDate})) + " to "+totext(maximum({@ConvertToDate}))
If, however, you really just want the first and last records, and you want it at the top of your report as a title (eg: in the Report Header), then I can't see how it can be done without using a subreport that looks at the same dataset, but only displays the first and last records (using the formulas below).
Stick this in the details section, and call it "HoldRecords" and suppress it:
whileprintingrecords;stringvar first;stringvar last;if recordnumber = 1 then first:={YourTable.YourField}; //if its the first record that crystal is displaying, store it in a variableif recordnumber = count({YourTable.YourField}) then last :={YourTable.YourField} //and again, but for the last record
Now create another formula, and put it into the report footer:
evaluateafter({@HoldRecords});stringvar first" to "stringvar last //will display "Jan07 to Apr07"
NOTE: if you have the report ordered by anything, this'll throw the record numbering, and therefore the first and last records, therefore... urgh.
Hope this helps... -
How to get last Record ior Total rows in For Loop Cursor ?

Hope i am clear
Any suggestions?

How to copy last record to a new record ?
Hello,
i have a question pls.
i want to copy last record to every new record
say,
multirecord forms has : Tank_no Last_measured Lab_Denisty
record1 : 1009aw 1532.94 .5796
what i want to do next record is copying last record (record1 ) as
record2 : 1009aw 1532.94 .5796
so the user may change the Last_measured only and not to have to rewrite the Tank_no and the Lab_Denisty cause it doesn't change.
May i do this ? if yessss, but How..?
Regards,
Abdetu..Hello poelger
i check it then found the following code :
DUPLICATE_RECORD Examples /*
** Built-in: DUPLICATE_RECORD;
** Example: Make a copy of the current record and increment
** the "line_sequence" item by one.
DECLARE
n NUMBER;
BEGIN
** Remember the value of the 'line_sequence' from the
** current record
n := :my_block.line_sequence;
** Create a new record, and copy all the values from the
** previous record into it.
Create_Record;
Duplicate_Record;
** Set the new record's 'line_sequence' to one more than
** the last record's.
:my_block.line_sequence := n + 1;
END; but then which trigger best fit the procedure should i use
w-c-r or w-n-r-i Triggers
and what is meant by line_sequence pls. ?
