  • Select the last character of a string

    Hello
    I want to select the last character of a string address. "For example, as a result of select ' 165 John Ave W '-'W '. I tried to use the RIGHT but it does not work. I am using sqlplus.

    SELECT RIGHT(ADDRESS,1) FROM addresses;
    ORA-00904: "RIGHT": invalid identifier

    I can't find that any select statement to get the result I want. Ideas?

    Thank you!

    You want: SUBSTR (, - 1).

  • any easier way to replace the last character in a string?

    That's what I got:
    select SUBSTR('tjgb005dy_01_31_08',1,LENGTH('tjgb005dy_01_31_08')-1)||'1' from dual;
    
    --
    tjgb005dy_01_31_01
    and I am enough fan of it. It's ugly and it's long.
    so, I wonder if you have better ideas?

    Thank you

    Even easier:

    select regexp_replace('tjgb005dy_01_31_08','.$','1') from dual;
    
  • Looking for the last element of a string defined in a specific character style

    I should find each space which is the last character of a string in a particular character style. For example, in the "123 456 789" passage (the underlined part here indicating a passage located in a specific character style), my ideal GREP search would produce a match after the number 6.

    How to do this?

    Define your character style in the Format Panel find, use this GREP: \s$

    $ is the match end-of-string location, and when you search for text in a style character style, the end of what this style is applied to is considered the end of the string.

  • Select from the table where the last character of the string is numeric

    Hello
    I have a table of STREETS with a field called ADDRESS. I want to select all the records in streets where the last character in the address is a number.
    Select ADDRESS of STREETS where regexp_like (substr (address,?,?,), '[0-9]');
    --? means that I don't know what to put here!

    I don't know if substr is the best approach to do this, because I want only the last character and the records are of different lengths.

    Thank you!

    Hello

    If you want to use regular expressions:

    WHERE     REGEXP_LIKE ( address
                  , '[0-9]$'
                  )
    

    You can get the same results, no doubt more effectively, without regular expressions:

    WHERE     INSTR ( '0123456789'
               , SUBSTR (address, -1)
               )     > 0

  • [JS] To find the last updated the story?

    Hello.

    I can find the last story added.  (app.activeDocument.stories.lastItem ())

    But I want to find the last updated the story.

    Is there a way?

    Hello..

    Updated the story means that it is many possibilities... for example, if you add a cahracter, deletion of a character, track changes, change of font etc...

    so every change attribute will give the last updated the story...

    I hope that you should check the possibilities!

  • Retrieve the Position of the last character of Textlayer

    Dear script Experts!

    I wonder if there is a way to get the properties of the position of the last character in a text layer.
    For example, I used this in ActionScript: txt.getCharBoundaries (txt.length - 1);

    Thanks for any help

    Mike

    Available properties for a text layer are:

    applyFill

    applyStroke

    Dialoguegeneral

    boxTextSize

    fillColor

    Police

    fontSize

    Justification

    pointText

    strokeColor

    strokeOverFill

    strokeWidth

    text

    follow-up

    Last I saw, by the data type character recovery was still not available. Even in AE CC. Any extraction layer text property is based on the first character in the text string. So if each character used a font, point size, kerning, etc. only the values of the first character could be found.

    Re: Is it possible to access the text by character properties via script?

    Some other posts here that speak of the location of the text layer:

    Attribute boxTextSize ADBE Text Document

    Get a text box anchor point after scaling

    You can always ask too.

    Thank you myDavey. It's not exactly what I was looking for, but he had good information on something else, I'm trying.

    I found the solution to my problem. This highlighted selection apparently called the object 'key '.

    And it can be used in the script as app.selectionKeyObject. This solves what I was looking for.

    And you can find the last selection by selecting the last item in the selection table.

  • How to find the last pasted paragraphs FMP?

    I'm sticking FMP several objects at once in a file (a file of changes to the sections containing the changebars) in the main text flow. I want a separator line to go at the end of each pasted section, so I try to insert one after the paste operation. But instead of a line between each section, all lines are added at the end of the file, after all the sections. So if there are 3 glued sections at the end of the file are three lines. My code is below, do you know how I could fix this?

    Thank you, Mark

    function copyPasteChanges (doc, chgRange) {}

    Select the section with changebar and copy it.

    doc. TextSelection = chgRange;

    doc. Copy();

    Prepare for the changes doc and paste there the modified section.

    var firstChgPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

    var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

    var changesTRange = new TextRange (changesTloc, changesTloc);

    changesDoc.TextSelection = changesTRange;

    changesDoc.Paste ();

    To go at the end of the file again (I think)

    var lastPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

    var dividerPgf = changesDoc.NewSeriesPgf (lastPgf);

    var TLoc = new TextLoc (dividerPgf, 0);

    changesDoc.AddText (TLoc, '_');

    }

    Hi Mark,

    The problem is that the dough does not occur when you think. The dividing line is added at the end of the file, but are not your actions of dough. Actually, I think that maybe a little random where pasta is produced, because this line:

    var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

    .. .is does not create a valid text location. You can check this by abandoning the service after:

    changesDoc.TextSelection = changesTRange;

    .. and look at where's the insertion point. It will probably be everywhere where you left it last, because the call is not valid. I can't tell you exactly why, except that it has something to do with the fact that you are using the last paragraph in the stream. There is something weird to try to define a range of full-paragraph text with the last paragraph. I'm sure it's related to how the last TFP in a stream does not show a mark of FMP, but beyond that, I don't know how to do what you're trying to do with the last paragraph.

    Having no knowledge of how do it right, any time I need to do this, I create a paragraph "dummy" at the end of the flow to fill that space strange 'last FMP", then do the work around it. In the end, I just want to remove fake TFP. I don't know if it's a good idea or not, but it's the only way I ever get it to work and it sorts the mirror how you could do this manually in the GUI.

    With this, I modified your script as follows, and it seems to work better. Note that I also modified the logic of how to find the last paragraph of the flow by writing a separate function. Your call to the 'FirstTextFrameInFlow' is OK, unless your doc begins to span several pages and/or begins with several empty pages. The function I wrote ensures that you really the last TFP in the stream.

    I hope this helps.

    Don't forget that last TFP is now fake TFP

    lastPgf = getLastPgf (changesDoc);

    var dividerPgf = changesDoc.NewSeriesPgf (lastPgf.PrevPgfInFlow);

    var TLoc = new TextLoc (dividerPgf, 0);
