Finding first occurrence of a numeric data in a string
Hi
Can you please suggest me in this.
I have a data set like following..
'LOMBORD 123'
'LOMBORDD'
'LOMBORDD45'
Here how i will ffind the first occurance of the numeric valu in each string there may be a space charecter like 'LOMBORD 123' .
As my database version is 9i i can't use regular expression.
Thanx in advance
Maybe something like:
SQL> set feedback on
SQL> WITH test_tab AS
2 (SELECT 'LOMBORD 123' col_1
3 FROM DUAL
4 UNION ALL
5 SELECT 'LOMBORDD'
6 FROM DUAL
7 UNION ALL
8 SELECT 'LOMBORDD45'
9 FROM DUAL)
10 -- end of test data
11 SELECT col_1,
12 TRIM (TRANSLATE (col_1, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', ' ')
13 ) numbers_in_col,
14 NVL
15 (INSTR (col_1,
16 TRIM (TRANSLATE (col_1, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', ' ')),
17 1,
18 1
19 ),
20 0
21 ) position_of_numbers
22 FROM test_tab
23 /
COL_1 NUMBERS_IN_COL POSITION_OF_NUMBERS
LOMBORD 123 123 9
LOMBORDD 0
LOMBORDD45 45 9
3 rows selected.

Grep to find first occurrence of a particular word in a story
Hello Grepers
I haven't had luck working out a Grep to find first / last occurrence of a particular word in a story.
To find the first occurrence of the word hello in a paragraph I would use this grep.
(Hello(?!=Hello*$))
For the last this works.
((?=Hello(?=.*Hello)))|(Hello(?!=Hello*$))
I have tried single line and multiline prefixes but they don't do the trick.
Waiting in suspence,
TrevorHi Marc,
Thanks for your reply, I'm glad you got my subtle hints.
1) First Hello in the paragraph(s)
Marc Autret wrote:
Also, it seems to me that the GREP patterns you've posted are wrong and only work by accident. For example:
(Hello(?!=Hello*$))
actually means: find 'Hello' if and only if the match is not followed by '=Hell' and 'o' zero or more times and an EOL.
Well Marc I made a Hell of a mistake!!!
I meant to write (Hello(?!=Hello.*$)) with a dot there which at least is not quite as stupid if not more correct.
In fact both (Hello(?!=$)) without a . and Hello(?!=^) work, well sort of work for the first Hello of the paragraph(s) depending on the were one start the search from (before the first Hello works otherwise it will find the next "first" Hello of the paragraph.
I said sort of because I naively presumed that GREP styles would work like GREPS, dumb hey.
I was really looking to use these GREPS in GREP styles, well you can't.
In a GREP style
(Hello(?!=$)) or any of its variants will apply the style to all occurrences of Hello in the paragraph.
I can partially circumvent this problem by adding a second GREP STYLE which applies an anti style to all words after the first Hello (?<=Hello).*
i.e. I have a want my first Hello to be bolded then set the first style for bold and the second to regular.
This however is not practical if one wants to auto style more than one word in this way in other words to do the same for the first Hi and the first Hello in the paragraph.
As a regular GREP solution providing that one starts the GREP search before the first occurrence of Hello It will work.
2 & 4) First and Last Hello in the story
Again these GREPs don't work using GREP styles, this I think is because GREP paragraph styles only look within the one paragraph at a time they are applied to. So they can't look at the preceding or following paragraphs to see if they contain Hello or not.
If I am correct I see no work around to this and am will to pay 10 Pounds, Euros or Dollars to whoever comes up with a non-script fully functional GREP styles solution for this (I think my money's safe)
Regarding the regular non styled GREPs they nearly work as stated.
When (?s)(Hello)(?!.*?\1) is used to find the last occurrence of Hello in the story, if the find tab is used it will firstly find the last Hello of the story then it will go back and find the one before that!! then it will go onto the next story.
Using the GREP in script works as stated.
The easiest way of course to find the first and last Hello in a story, document etc. by script would be
app.findGrepPreferences.findWhat = Hello"
myFinds = myWhatEver.findGrep();
First occurrence myFinds[0], last occurrence myFinds[-1].
HOWEVER NOT PARTICULARLY EFFICIENT!
3) Last occurrence of Hello in paragraph.
This one works perfectly both with regular GREPS and GREP styles.
In summary
GREP STYLES: only the (Hello)(?!.*?\1) last Hello in the paragraph GREP works.
GREP FIND TAB: the first Hello in the paragraph GREP finds the first Hello after the cursor, the first in the story works in the limited way as written, last in story has the problem of finding the second last Hello after finding the last Hello, Last in paragraph works flawlessly.
GREP SCRIPTING: all work without problem except for the first Hello in the story that has the problem of needing to extract the last 5 letters which for my automatic text / GREP changer is a bit of a problem but for general scripting would not be problematic.
Once again Marc thanks for your input, I doubt there's much if anything to add on the topic maybe Laurent Tournie from indigrep.com might have some ideas. I don't know his contact details so if you think it's a good idea please can you send him a tweet / mail.

How to use "FIND FIRST OCURRENCE...." with a very long text
When I store a certain text in variable p_texto -> FIND FIRST OCURRENCE is ok; sy-subrc = 0.
When Instead of assigning a text I read a long text from an excel into p_texto variable ->
FIND FIRST OCURRENCE is not working; sy-subrc = 4.
DATA: p_texto(5000).
DATA: posicion TYPE match_result.
p_texto = 'HI THIS IS THE FIRST LINE#AND THIS ONE THE SECOND LINE'.
FIND FIRST OCCURRENCE OF '#' IN p_texto RESULTS posicion.
How could I manage this problem?
Thank you very much in advance.As I told you before, the problem is not the length of the line.
The problem is that you see in your variable "#", but it is not "#". It could be a carriage return, a tabulator or other character that doesn't know how to display.
In my opinion you should search for cl_abap_char_utilities=>newline.

Hi gurus!
I want to check if the FI period is closed or not. If it is closed I want to find the open period, and then the first date in this period. How would you solve this?
check if FI period is closed.
If period is closed.

according to filter:

It sounds like you want a Top-N Query , something like this:
WITH got_nums AS
SELECT table_x.* -- or list columns wanted
, ROW_NUMBER () OVER (ORDER BY call_date ) AS a_num
, ROW_NUMBER () OVER (ORDER BY call_date DESC) AS d_num
FROM table_x
WHERE mobile_no = 989
AND call_date >= DATE '2013-04-25'
AND call_date < DATE '2013-04-26' + 1
SELECT * -- or list all columns except a_num and d_num
FROM got_nums
WHERE 1 IN (a_num, d_num)

Find All Occurrences always fails within loop
Dear forumers,
There's this strange problem that requires a fix.
Finding all occurences of '#' works fine here:-
REPORT zz_test.
DATA: lv_text TYPE string,
ls_result TYPE match_result,
et_release type table of yytc_release,
lt_result TYPE match_result_tab.
lv_text = '"RFC-1234#Create ""Payroll"" under NL directory"'.
FIND ALL OCCURRENCES OF REGEX '#'
IN lv_text
RESULTS lt_result IGNORING CASE IN CHARACTER MODE.
IF sy-subrc = 0. " SY-SUBRC is always 0
READ TABLE lt_result INTO ls_result INDEX 1.
WRITE :'Offset: ' .
WRITE: ls_result-offset .
WRITE: lv_text+00(ls_result-offset).
ENDIF.
But it always fails here, within a loop at an internal table:-
SELECT * .... INTO TABLE it_jira ...
LOOP AT it_jira ASSIGNING <jira>.
<release>-summary = <jira>-summary.
IF <release>-type CS 'Subtask'.
" <release>-summary is of data type CHAR255
PERFORM get_subtask USING <release>-summary.
ENDIF.
ENDLOOP.
FORM get_subtask USING pv_summary TYPE yytc_release-summary.
DATA:
lv_string TYPE char255,
lv_final TYPE char255,
lv_summary TYPE string,
lv_strlen TYPE i,
lt_result TYPE match_result_tab.
lv_string = pv_summary. " LV_STRING = '"RFC-1234#Create ""Payroll"" under NL directory"''
CONDENSE lv_string.
lv_strlen = STRLEN( lv_string ).
lv_strlen = lv_strlen - 1.
IF lv_string+0(1) = '"' AND lv_string+lv_strlen(1) = '"'.
lv_strlen = lv_strlen - 1.
WRITE lv_string+1(lv_strlen) TO lv_final+1(254).
ENDIF.
lv_summary = lv_final.
" FIND ALL OCCURRENCES OF '#'
" IN lv_summary
" RESULTS lt_result IGNORING CASE. * SY-SUBRC is always 4 here too
FIND ALL OCCURRENCES OF REGEX '#'
IN lv_summary
RESULTS lt_result IGNORING CASE IN CHARACTER MODE.
IF sy-subrc = 0. " SY-SUBRC is always 4 here - why?! :(
ENDIF.
CLEAR: lv_string,
lt_result.
ENDFORM. " GET_SUBTASK
Only when the string LV_SUMMARY is edited from within the debugger (add space to the string prefix, etc), the SY-SUBRC will be 0 and there'll be data found in LT_RESULT.
How can I resolve this issue? Please do help. Thanks.I think the subtle difference is that in your first example the character is actually '#' whereas in the second example it is actually another (unprintable)value such-as line-feed and only APPEARS to be '#'.
You must find out what the value in question is(will it always be the same value?) and then replace that instead of '#'. -
From where to get "First day of the week" data for all the locales, is it present in CLDR spec 24?
I am trying to get "First day of the week" data from CLDR spec24 but cannot find where to look for it in the spec. I need this data to calculate numeric value of "LOCAL day of the week".
This data to implement "c" and "cc" day formats that equals numeric local day of the week.
e.g if "First day of the week" data for a locale is 2 (Monday) , it means numeric value for local day of the week will be 1 if it is Monday that day, 2 if it is Tuesday that day and likewise.Hi
If you want to week to be started with Sunday then use the following formula:
TimestampAdd(SQL_TSI_DAY, 1-DAYOFWEEK(Date'@{var_Date}'), Date'@{var_Date}') if it's retail week(starts from Monday) then the follow below:
TimestampAdd(SQL_TSI_DAY, 1-DAYOFWEEK(Date'@{var_Date}'), Date'@{var_Date}')
I'm assuming var_Date is the presentation variable for prompt...

Find the number of consecutive numeric digits in string
I am trying to see if a string has say 9 consecutive numeric digits in it but it will only work if the long string of numbers is the first string of numbers.
e.g.
This would recongnise the following string (if p_len = 9)
Tel number 20 20 30 369 for 2nd meeting
but would not recongnise the following
For 2nd meeting tel 20 20 30 369
Could anyone give guidance on how to proceed / a better way of find consecutive numbers in a string?
Thanks
Simon
Code sample -
LOOP AT TLINETAB.
Remove blank spaces
CONDENSE TLINETAB-TDLINE NO-GAPS.
Find first number and its position *
IF TLINETAB-TDLINE CA '0123456789'.
pos = sy-fdpos.
Does the next x characters contain only numbers?
IF TLINETAB-TDLINE+pos(p_len) CO '0123456789'.
append i_report.
endif.
ENDIF.
ENDLOOP.Dear Simon,
you want to check for consecutive numbers in a string. Then you may do the following -
1. Get all the numbers in the given string into a table in a sequencial order, that is the order in which they appear in the string
2. Once you have all the numbers you may find out if the numbers are consecutive or not. The following is the code which is not tested
lv_len = 1.
lv_pos = 1.
lv_strlen = strlen ( lv_str ).
do lv_strlen times.
lv_alpha = lv_str+lv_pos(lv_len).
if lv_alpha co '0123456789'.
append lv_alpha to lt_number.
endif.
lv_pos = lv_pos + 1.
enddo.
loop at lt_number into ls_number.
if lv_no is initial.
lv_no = ls_number.
lv_no = lv_no + 1.
else.
if ls_number eq lv_no and
lv_consec is initial.
lv_consec = c_x.
else.
clear lv_consec.
endif.
endif.
endloop.
if lv_consec eq c_x.
* !!! string has consecutive numbers
endif.
Hope it helps. Thank you.

Incorrect numeric date displayed in month view
today is Saterday July 1st however when I open iCal it shows the current date to be Friday June 30th... (the icon on the dock is correct showing the 1st) In day and week views iCal believes that the current date is Friday June 30th however stranger things happen when viewing by month. Here the current DAY is correct (showing Saturday in light blue) however all of the numeric DATES are shifted ahead by one. My calendar shows the first day of July being Sunday with the 4th of July being Wednesday. All the events in the calendar are on the correct DAY ie, the 4th is on Tuesday, etc. Also the top of the month window says "June 2006" even though I am looking at the events in July.
Very strange... any ideas on what is happening are appreciated. Oh and the date on the computer is correct... go figure.
Thanks

PowerBook G4 Ti Mac OS X (10.4.7)The real answer is given: No, this is not configurable as it depends on how many weeks a month spans; rarely this is 4 weeks, most often this is 5 weeks, sometimes this is 6 weeks. It is called the "'Month" view, not the "4-weeks view" or anything like
that.
Your feature request is of course valid and to submit it as such, it is best to contact Microsoft Support by phone. You may need to provide credit card information to open a case but it of course won't be charged for a feature request. You'll get a reference

You may want to refine your request with a business case as well and give a clear example of what you want it to look like and what exactly should be configurable.
For instance, the default Multi-Week View should show; last week, this week and the next 2 weeks.

Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
