Returning a piece of text in a SELECT

Hello!
I'm doing a search in a table that has four fields:
ID
NAME varchar(128)
TEXT1 varchar(500)
TEXT2 varvhar(500)
Well, I need to search for a word in fields TEXT1 and TEXT2. My
first step is to do the following:
SELECT ID,NAME
FROM TABLE
WHERE CONTAINS(TEXT1,'word',1) > 0
AND CONTAINS(TEXT2,'word',2) > 0
Well, til here is all ok, but now... I need something more
difficult:
I need to obtain for each ID, the piece (or the first piece) of
text where 'word' was found on, considering that this word can
be allocated in TEXT1 or in TEXT2.
Thank you very much!!

Carlos...
I'm not familiar with the CONTAINS function, but I'll assume it
returns a number greater than zero when the desired condition is
met.
The way your where clause is written, the result set will
include only those rows from TABLE where 'word' is in BOTH TEXT1
and TEXT2.
I'm guessing about what you want, but here goes...
SELECT id
     , name
     , CONCAT( DECODE( SIGN( CONTAINS(text1,'word',1) )
                     , 1, CONCAT( 'From text1: '
                                  SUBSTR( text1
                                  , 1
                                  , INSTR( text1
                                         , 'word'
                                         ) + 3
             , DECODE( SIGN( CONTAINS(text2,'word',1) )
               , 1, CONCAT( ' From text2: '
                            SUBSTR( text2
                            , 1
                            , INSTR( text1
                                   , 'word'
                                   ) + 3
             ) AS text
FROM table
WHERE CONTAINS(text1,'word',1) > 0
   AND CONTAINS(text2,'word',2) > 0
     ;The column text should contain the contents of columns text1 and
text2 up to 'word', prepended with the 'From text1;' and 'From
test2:'
If the AND in the where clause is replaced with and OR, then the
parts of text1 and text2 will only be returned if the
contain 'word'.
I did not test this code.
Good Luck...

Texting on iPhone 5. When texting to multiple people why does the contact list return to the "A"s after you select a contact and try to add the next one in order?

Texting on iPhone 5. When texting to multiple people why does the contact list return to the "A"s after you select a contact and try to add the next one in order? This really slows you down when trying to contact 50 people with information. iPhone 4 worked just fine. Any suggestions on how to fix this?

None of my pictures that I uploaded into iPhoto are in my Finder under Pictures. Should I copy and paste my folders from iPhoto into here, in case something happens to my iPhoto program (in addition to backing them up onto an external hard drive like I already do)?
No, that's just wasting space. A back up needs to be on a different disk.

Getting the Physical Length of a Piece of Text (in mm etc.) in Javascript

I'm trying to write a script in Indesign CS5 (Windows) that can measure the physical, 'rendered' length of two pieces of text of similar length (in mm etc.), calculate the average length of the two, and adjust the tracking/horizontal scale of one or both of the pieces of text so that the physical length of both texts are the same.
I need a script because this task must be done thousands of time in a long document.
I'm struggling to find a way to access the 'rendered' length of a piece of text in Javascript.
I know among the attributes of a text box is whether the text has overrun. So I could copy the text to a special text-box, and use a for loop to reduce the dimentions of the text box, 1mm at a time, until the text box overruns, thus determining the length..
I could also get the length of a rendered string using python with it's built in GUI toolkit Tkinter:
http://stackoverflow.com/questions/2922295/calculating-the-pixel-size-of-a-string-with-pyt hon
And then have an indesign script that takes some data from the python script and sets the tracking/horizontal in Indesign with some fudge factors.
Both ideas seem like real kludges.
Any other suggestions?
Many thanks
David

You can simply iterate through each line in text to get the widest line. Something like this:
Main();
function Main() {
    var text = app.selection[0],
    minLength, maxLength, start, end;
    for (var i = 0; i < text.lines.length; i++) {
        start = text.lines[i].characters[0].horizontalOffset,
        end = text.lines[i].characters[text.lines[i].characters.length-1].horizontalOffset;
        if (minLength == undefined || start < minLength) {
            minLength = start;
        if (maxLength == undefined || end > maxLength) {
            maxLength = end;
    var length = maxLength - minLength;
    $.writeln(length);
But this approach seems to be a little less precise than creating outlines since (I guess) it measures up to the beginning of the last character; discretionary hyphens, line brakes, etc. are not included into the measurement.

Adding a rectangle behind every piece of text in CS5

Hi,
I am making a series of map tiles (30) and would like to have a white rectangle behind every peice of black text in a certain layer. I know how to add a rectangle and position it behind the text, but want to avoid this repetive process.
I understand that each piece of text has a 'bounding box' - is there a way to add a fill to this box for all text at once?
Thanks,
Mike.

Mike,
You may:
1) Select all the instances of Type,
2) In the Appearance palette flyout tick Add New Fill, drag it down below Characters, and change its colour to white,
3) With the white Fill selected, Effect>Convert to Shape with the desired oversize.
Edit: Once again, hi Kurt.

Join multiple pieces of text

Does anyone know of a script that will take little pieces of text in CS4 & CS5, and join them into one piece so that the text is easier to edit? I've tried joining the text by selecting it, cutting it , and putting it into a text area, but the type often gets scrambled doing it this way.

There are a couple of scripts already about that do this… Is your broken up text from PDF where the kerning shatters it? This link has 2 examples:

Editing a PDF file with Acrobat XI pro... some "text" is not selectable and vanishes upon saving

Hi folks.
I've googled around for a few hours, but I'm completely stumped with this one.
I'm trying to edit a .pdf file that was generated from Word 2007. Mostly it edits fine, but for reason some of what appears to be text isn't selectable with the text and image editor... in fact it doesn't even have a bounding box around it. When I move around the document or save it in acrobat pro, the "text" then vanishes.
I include a dropbox link to a partial screenshot image which shows what I'm talking about. You can see that the italic bold A doesn't have a box around it in some cases.
https://www.dropbox.com/s/42i8xms78lvw12b/Screenshot%202014-02-07%2011.19.07.png
Can anybody kindly shed some light on what I'm doing wrong?
Thanks!

Hi Bill. Thanks for replying.
Unfortunately, I don't have the option of using the original DOCX file. The author lost it, leaving only the pdf around
I'm using AA XI 11.0.06. Upgraded this morning. That's running on Windows 7 Ultimate 64.
I get the boundary boxes by clicking on the 'edit text and images' tool, and they appear. Or don't in this case
I only need to change a few characters in the file. However, even just opening up the file in AA and then saving, the "A = " "text" gets deleted.
Could it perhaps be something to do with embedded or missing maths fonts on my machine? I mean, I don't get any warnings, just can't do anything with the A and AB italic bold text.
Thanks!

Change of variable text in BEx selection screen

Hi all,
in our BW system the key users are allowed to create queries and also create variables. In some cases, especially for often used info objects like 0DATE the number of variables is increasing very quickly. The reason for this is, that 0DATE is used for a big variety of meanings e.g. delivery date, order date, invoice date etc.
So the users always create new variables only to have a meaningful description in the BEx selection screen, because they do not want only "date" to be displayed here. As result we have many different varianbles with exactly the same technical settings with only different names.
So my question is: Is it possible to change the diplayed text in the selection screen for each query without having to create a new variable?
Thanek you and best regards

Hi Stephan,
Changing the diplayed text in the selection screen for each query is not possible.You have to create a new variable for each query.

When I run your query, I get NULL for sequence_no on the last 2 rows, where building_id=3000. The numbers 99 and 100 don't seem to occur in either table. Did you post the worng sample data and/or results?

     ,     ROW_NUMBER () OVER ( PARTITION BY building_id

ORDER BY      sequence_noThat means the row with the lowest sequence_no (for each building_id) will get r_num=1. If you want a random row from that building_id to be chosen as #1, then you can change the analytic ORDER BY clause to

How to Add/Concatenate to a text field, values selected in a combo box

I have a combo box form field that allows the user to select a value from a list and click on an Add button. The Add button should add/concatenate the vaue selected to a text field in order to create a list of values selected. I'm not sure how to do this using Javascript in Acrobat? I know I need to add the javascript to the Add button's Mouse Up action. Any help would be greatly appreciated. Thanks!

Thanks so much - it works!

Let's say the text field's name is "Text1", and the combo is called "Combo1". You can then use this code as the MouseUp script of the Add button:
var f1 = this.getField("Text1");
var f2 = this.getField("Combo1");
if (f1.value=="") f1.value = f2.value;
else f1.value = f1.value + ", " + f2.value;

at selection-screen.
   concatenate 'Today is' date into text.
   message text type 'I'.
If second
parameters pa_text type c length 50.
at selection-screen on date.
if date is not initial.
    concatenate 'Today is' date into pa_text.
enidf.
at selection-screen output.
   "show it as read only
   loop at screen.
    if screen-name = 'PA_TEXT'.
           screen-input = abap_false.
          modify screen.
    endif.
   endloop.

How to get the text boxes and select lists dynamically?

Hi,
I have a requirement such that I need to create the text boxes and select lists depending on the user input at the run time. It means that if the user requires four text boxes/select lists then I need to have 4 such thing. If the user need 6 then I need to have 6.
The design may be such that initially only one text box/select list will be available when the page launches. Then as ad when the user asks for more those will be available to the user accordingly.
regards,
Dipankar.

You can use Ajax to call textboxes and select list based on what user enters.
Otherwise make those items conditional and based on what user enters you can display textbox or select list.
You can call Single Textbox and Select List using Ajax for any number of conditions.

Chandra

Hi,
You mean to say parameter in selection screen
Just press F1 on parameter you will get all the option available for the parameter
for defaulting text just give your text in DEFAULT option for the parametr
And for disabling this checkbox you can explore the LOOP AT SCREEN concept
In at selection screen output event you can modify the selection screen.just give one modif id for your
paramete and use this at selection screen output event , loop at screen and modify screen with the screen input = 0
for ur parameter.
Thanx
