How to select the last elements in a string

Hi Guys
I am using UART RS232 protocol and i need to calculate the check sum. My data came in decimal and in the end it must be doubles to manipulate it. So my problem is, for example, the sum of all elemants is in decimal 1742 and in hex is 6CE and i wont only the last two elemants, CE that corresponds to 206 that is the result of my checksum. Can anyone help me?
Thanks
Solved!

Thanks Syrpimp
My data came from HMI in decimal like the example that i show above. Each cell is a value. You used an array, but i think that i can't use it because it must be done automatically and the data field have variable length.
The UART protocol frame has a start frame field that corresponds to two ‘{‘ characters and an end frame field that corresponds to two ‘}’. Additionally, besides the data field, that has variable length, it has a byte that corresponds to the command type and another that is the checksum. The following table illustrates the protocol.
Bytes considered in checksum

Data1
Data2

Data4

CHK SUM
End Frame
1 Byte CHK SUM (sum of all data bytes truncated to 1 byte)

How to Select the last price of parts

Hi Gents,
I have below table
TranNum | TranDate | PartNum | Price
1 | 1/1/15 | 111 | 5
2 | 1/5/15 | 212 | 7
3 | 1/7/15 | 111 | 4.5
4 | 1/8/15 | 212 | 6
5 | 1/9/15 | 212 | 5
I need to create new view to select last price per part.
TranDate | PartNum | Price
1/7/15 | 111 | 4.5
1/9/15 | 212 | 5
Thanks in advance.
Nothing is impossible

Something like this will work as well...
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
DROP TABLE #temp
GO
CREATE TABLE #temp (
TranNum INT PRIMARY KEY,
TranDate date,
PartNum int,
Price decimal(10,2)
CREATE UNIQUE NONCLUSTERED INDEX ix_Temp_PartNum_TranDate ON #temp (
PartNum,
TranDate
INCLUDE (
Price
WITH (DATA_COMPRESSION = PAGE)
INSERT INTO #temp (TranNum,TranDate,PartNum,Price)
VALUES
(1 ,'1/1/15 ',111,5),
(2 ,'1/5/15 ',212,7),
(3 ,'1/7/15 ',111,4.5),
(4 ,'1/8/15 ',212,6),
(5 ,'1/9/15 ',212,5)
SELECT
t1.TranNum,
t1.TranDate,
t1.PartNum,
t1.Price
FROM
#temp t1
WHERE EXISTS (
SELECT 1
FROM #temp t2
WHERE t1.PartNum = t2.PartNum
GROUP BY t2.PartNum
HAVING t1.TranDate = MAX(t2.TranDate)
Please note... Without any indexing on PartNum & TranDate, my solution will perform about the same as Martin's solution (currently the fasted of the supplied solutions).
Adding the following index, however, will show that the "EXISTS" solution can dramatically out perform the "NOT EXISTS" solution...
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
DROP TABLE #temp
GO
CREATE TABLE #temp (
TranNum INT PRIMARY KEY,
TranDate date,
PartNum int,
Price decimal(10,2)
CREATE UNIQUE NONCLUSTERED INDEX ix_Temp_PartNum_TranDate ON #temp (
PartNum,
TranDate
INCLUDE (
Price
WITH (DATA_COMPRESSION = PAGE)
INSERT INTO #temp (TranNum,TranDate,PartNum,Price)
VALUES
(1 ,'1/1/15 ',111,5),
(2 ,'1/5/15 ',212,7),
(3 ,'1/7/15 ',111,4.5),
(4 ,'1/8/15 ',212,6),
(5 ,'1/9/15 ',212,5)
SELECT
t1.TranNum,
t1.TranDate,
t1.PartNum,
t1.Price
FROM
#temp t1
WHERE EXISTS (
SELECT 1
FROM #temp t2
WHERE t1.PartNum = t2.PartNum
GROUP BY t2.PartNum
HAVING t1.TranDate = MAX(t2.TranDate)

Select the last saved records in a table

I all
I have this struct in a table
create table INT_OBJ
IDOBJ NUMBER(15) not null,
IDERP NUMBER(15),
IDE NUMBER(15),
CPO VARCHAR2(20),
VLR VARCHAR2(2500),
VLRC VARCHAR2(2500)
How to Select the last saved records in a table. I think usea a temp table for put the last row read and begin to read in the next row.
The table is reading each four hours.

Theoretically it can be done with ORA_ROWSCN and enabled ROWDEPENDENCIES, but there are so many nuances, so only adding column for ordering is right.

How can I select the last 2 chars of a string

Hello all,
I am trying to select the last 2 characters of a string to match them to another string. This is for a Poem generator that contains 20 or so words and I have to pick 2 words at random, them look at the last 2 characters to see if they match in each string. Say "Plain" and "Rain" would match because they both have "in" at the end. The length of each word could vary. I don't want this doing for me just what Method should I be looking at.
Thanks.

hi,
try this:
public class StringTest {
     public static void main(String args[]) {
          StringTest obj = new StringTest();
          obj.same();
     void same() {
          String rain = new String("Rain");
          String plain = new String("Plain");
          int rainLength = rain.length();
          int plainLength = plain.length();
          if(rain.substring(rainLength-2).equals(plain.substring(plainLength-2))) {
               System.out.println("same");
          else {
               System.out.println("different");
}you can use the length method to get the length of a string and then use the substring method, passing it length-2, so get the last 2 chars.

How to get the last day according to fiscal period input in selection scree

Hello expert
how to get the last day of fiscal period input.
the fiscal period inculdes 1-16
when fiscal period is greater than 12, only calculate the last day of 12nd month
your solution will be apprecaited, FM existing?
thank you
Kevin

Hi,
when you give a particular date in any month
the following fm will give you the last date of that month
here you can give
R_FDATE-HIGH as 01 and month as the period you wnat and year for current year
concatenates '01' month year into r_fdate-high separated by '.'.
then it will give g_ltdt for that month and year which wil be the last date of that month
    CALL FUNCTION 'RP_LAST_DAY_OF_MONTHS'
      EXPORTING
        DAY_IN            = R_FDATE-HIGH
      IMPORTING
        LAST_DAY_OF_MONTH = G_LTDT
      EXCEPTIONS
        DAY_IN_NO_DATE    = 1
        OTHERS            = 2.

Hi, San,
Here's one way:
WITH     sample_data     AS
     SELECT DATE '2011-04-04'     AS dt
     FROM     dual
SELECT dt
,     TO_CHAR (dt, 'WW')     AS week_num
,     NEXT_DAY ( dt - 1
           , TO_CHAR ( TRUNC (dt, 'YEAR') - 1
                  , 'Day'
           )          AS end_o_week
FROM     sample_data;Another way is to use date arrithmetic:
WITH     sample_data     AS
     SELECT DATE '2011-04-09'     AS dt
     FROM     dual
SELECT dt
,     TO_CHAR (dt, 'WW')     AS week_num
,     TRUNC (dt, 'YEAR')
      + (7 * CEIL ( (dt - (TRUNC (dt, 'YEAR') - 1))
            / 7
      - 1               AS using_date_arithmetic

I dont know what table names and fields you have but
say you have a table called XYZ which has a primary
key field called keyID.
So in order to get the last row inserted, you could
do something like
Select *
from XYZ
where keyID = (Select MAX(keyID) from XYZ);
Good Luckwhat gubloo said is correct ...But this is all in MS SQL Server I don't know the syntax and key words in MYSQL
This works fine if the emp_id is incremental and of type integer
Query:
select      *
from      employee e, (select max(emp_id) as emp_id from employee) z
where      e.emp_id = z.emp_id
or
select top 1 * from employee order by emp_id descUday

How to find the Last modified date and time of a package

Hi,
We need a clarification on how to find the Last modified date and time of a package in Oracle. We used the example below to explain our scenario,
Lets consider the following example
Let A, B be two packages.
Package A calls the package B. So A is dependent on B.
When A is compiled the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS gets updated.
Now there a modification in package B so it is compiled. There is no modification in package A.
Now when the package A is executed the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS gets updated but we did not make any change in Package A. Now we need to find last modified date and time of the package A . So we can not rely on the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS . Can u please tell us any other solution to get last modified date and time of the package A .
Regards,
Vijayanand.C

Here is an example:
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 10:57:32 2004-05-20:10:57:32 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 10:59:04 2004-05-20:10:59:04 VALID
SQL> CREATE OR REPLACE PROCEDURE A AS
2 BEGIN
3 NULL;
4 NULL;
5 END;
6 /
Procedure created.
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 11:01:28 2004-05-20:11:01:28 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 10:59:04 2004-05-20:10:59:04 INVALID
SQL> EXEC B
PL/SQL procedure successfully completed.
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 11:01:28 2004-05-20:11:01:28 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 11:01:53 2004-05-20:11:01:53 VALID
Note that the date under the column 'created' only changes when you really create or replace the procedure.
Hence you can use the column 'created' of 'user_objects'.

How to find the last modified date of a workflow.

How to find the last modified date of a workflow.
thanks.

Hi,
There is nothing as standard that does this - you could write some code to determine the latest begin_date from each of the workflow tables and assume that this was the last time that the definition changed.
What you need is something like this:
select max(wfa.begin_date)
from   wf_process_activities wpa
,      wf_activities          wfa
,      wf_item_types_tl       wit
where wpa.activity_item_type = wfa.item_type
and    wpa.activity_name      = wfa.name
and    wfa.version            = (select max(version) from wf_activities wfa1 where wpa.activity_item_type = wfa1.item_type and wpa.activity_name = wfa1.name )
and    wpa.process_item_type = 'your item type'
and    wpa.process_item_type = wit.namewhich I think gives what you want.

How to select the first record?

Hi,
Could anyone tell me how to select the first record of every
group?
ex, I want to find out every customer their first purcaseDate.
CustomerID PurcaseDate Region
A00000001 2001/01/01 AA
A00000001 2001/02/02 AA
A00000002 2001/03/01 AC
A00000002 2001/05/07 AC
A00000003 2001/03/05 DD
result:
A00000001 2001/01/01 AA
A00000002 2001/03/01 AC
A00000003 2001/03/05 DD
Thanks

Vincent,
You could do it as Carl suggested, with a couple of
corrections. You would need to include the CustomNo column in
the order by clause of your cursor. You would also need to add
a where clause to your update statement, otherwise everywhere
Region in the table would be updated with the same value of the
last CustomNo in the cursor, regardless of the CustomNo in the
table. See corrected code below:
DECLARE
CURSOR     cust
IS
SELECT     DISTINCT CustomNo, Region, Purchase_Date
FROM       my_table
ORDER BY   CustomNo, Purchase_Date, Region;
c_customer VARCHAR2 (9) := '...';
c_region   VARCHAR2 (2) := '..';
cntr       NUMBER := 0;
BEGIN
FOR x IN cust
LOOP
    IF x.CustomNo != c_customer
    THEN
      c_customer := x.CustomNo;
      c_region := x.Region;
    ELSE
      UPDATE my_table
      SET    Region = c_region
      WHERE CustomNo = c_customer;
      cntr := cntr + 1;
      IF cntr = 25
      THEN
        COMMIT;
        cntr := 0;
      END IF;
    END IF;
END LOOP;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
    NULL;
END;
Another option is that you could just use one update statement,
like this:
UPDATE my_table a
SET    Region =
       (SELECT DISTINCT Region
        FROM   my_table b
        WHERE (CustomNo, Purchase_Date) IN
               (SELECT   CustomNo, MIN (Purchase_Date)
                FROM     my_table
                GROUP BY CustomNo)
        AND    a.CustomNo = b.CustomNo)

Depending on your used databasee version, there are several options available, here are just a few examples:
Sorted Inline-Views & rownum:
SELECT *
FROM (SELECT *
          FROM user_objects
         ORDER BY timestamp desc)
WHERE ROWNUM <= 5;
;Inline-View with analytic function:
SELECT *
FROM (SELECT uo.*, ROW_NUMBER() OVER (ORDER BY timestamp desc) rn
          FROM user_objects uo
WHERE rn <= 5;
;C.
