Prepare a document to insert a row that contains the Blob column. Is what sense this correct?

When we prepare the statement to insert a row that contains the Blob column. Is what sense this correct? And what is the difference? Does anyone know?

1 Preparestatement.setBlob(parameter number, blob type object)

2 Preparestatement.setBlob(parameter number, inputstream type object)

This link shows the test I did.

I answered in your other thread and provided a link to the JDBC Dev Guide section, which explains how to work with type LOB and BFILE data.

Have you read this article from doc?

Did you read my response to your other thread?

In java, a BLOB is just the index that gives you access to the content. In your case, you access by selecting a locator BLOB existing and getting his inputstream. This inputstream is what allows you to access the content real blob.

The Locator is just that; It specifies the LOCATION of the blob content, but NOT the content.

  • Find the Document color space &amp; find samples that contain the content of the text block.

    Hello world

    I tried to figure this out for the last three days. I've tried everything I can think and search all over the internet (GitHub, Forums, etc.). I'm not a javascript Wizard, and certainly a Newb Extendscript.

    I have a datamerge which creates the attached fields from a CSV file. It is an internal reference to a color code. I am able to test cycle using the for loop an enter the color code. But I can't seem to find a way to seek the shades. One thought was to put in a table and sift through them. The color code provided is not swatch set name that makes things interesting. For example, name is 2297R - 19995, where 2297r is the color code for the text frame. Possible?

    function main(){
    // setup some variables

  • Printing of documents that contain the letter and legal-size pages - Laserjet 600 M602

    We have a printer Laserjet 600 M602, that does not automatically select a tray to print every time someone tries to print a document that contains the letter so many pages of legal size.  The default printer for the Tray 1 (Manual power) and the user will have to walk over to the printer and the printer to select the correct tray.  I went in the printers settings via the web interface and I set the tray settings to the following: Tray 1 - any Type of Size/Any, bin 2 - letter/plain, plateau 3 - legal/Plain and it still does not print correctly.  Unfortunately for the printer settings, it was on that I'm comfortable doing.  I read the print driver may have changed, but we use the driver included with the disc and I guess that it would be sufficient that this driver.  Does anyone know of some setting that I might be able to change the printer or if it is indeed a print driver problem?  Any comments would be appreciated.

    Thank you

    I was able to receive help this morning from HP support.  He turns out, there were two things that I needed to change.  The first is that when printing from a pdf file, there is an option in the print area for "Choose paper according to the size of PDF page source" and the second thing, it was with the printer printing preferences.  In the printing preferences, under the "Printing shortcuts" tab, the paper Type has been set to Prepunched.  We changed this Unspecified.  After making these two changes, the user is able to print correctly in the printer.

  • Is it possible to get the name of the folder that contains the current document?

  • Cell that contains the formula paste between spreadsheets

    How do I paste the value of a cell that contains the result of a spreadsheet formula has, in a worksheet cell B and still have the operation of the formula? OS 10.11.14, numbers 3.6.1.

    Hi dad,

    It depends on what you mean by "still have the operation of the formula."

    If simply paste you it into a new table in another document, the formula will be stuck more or less intact, but it will not reference all the cells on the original table. If he refers only the cells on the table where he came from, he can refer to these same cells or cells in the same position relative to the new location on the table to which it is glued. You will have probably the best success with her work on the new table, if you copy and then paste the formula itself, rather than the containing cell.

    Repeat what I have not quite clear in the first line: the numbers documents cannot reference cells in other documents of numbers.

    Kind regards

  • The feature you are trying to use is on a network that is not available. Click OK to try again or enter a different path to the folder that contains the installation packagr 'TrayApp.msi'

    Original title: trayapp

    When I open the computer message appears, the component you are trying to use is on a network that is not available. Click OK to try again or enter a different path to the folder that contains the installation packagr 'TrayApp.msi' in the box below.
    C:\Users\user\AppData\Local\Temp\7zS5216\setup\TrayApp\
    When I click ok the message this way that c:\users\user\appdata\local\temp\7zs5216\setup\trayapp\ is not found. Verfy that you have access to this location and try again or try to find the 'TrayApp.msi' in installing a package file from which you can install the product'TrayApp.
    When I try to cancel the warning message, is that an installation package for the TrayApp product is not found. Again the installation again using a valid copy of the 'TrayApp of installation' package. I already uninstalled all HP products, but this message is still bothering me, how to solve this problem?

  • How to get a paragraph that contains the string selected in FDK?

    Hello

    I am writing a program that extracts content of the paragraph that contains a selection string. This program runs in the interaction point menu. When the user click on the menu item. The process as follows:
    1. find a chain on a document, for example: F_ApiFind ("ABC").
    2. the F_ApiFind ("ABC") API returns the F_TextRangeT structure.
    3. the string "ABC" has been highlighted on the document.

    Here's my question:
    How can I write code to locate an object ID paragraph (pgfId) that contains the string (or object) 'ABC '?.
    As the 'ABC' object belongs to the current paragraph, how can I get section ID (pgfId) and then get the content of the entire paragraph
    without a loop through FP_FirstFlowInDoc, FP_FirstTextFrameInFlow, FP_FirstPgf and FP_NextPgfInFlow.

    Thank you very much for you help,

    Thai Nguyen

    Hi thai,

    Paragraph ID is returned as part of the structure of F_TextRangeT, as the Member "objId". Let's say you have:

    F_TextRangeT tr;

    ... then:

    TR = F_ApiFind (...);

    On an action to search with success, "tr" will contain the pgfId of the paragraph. I'm assuming you're looking for a string that is entirely contained in a paragraph, in which case two ways contains the ID of the paragraph:

    tr.beg.objId

    TR.end objId

    If you want to retrieve all the text in the paragraph after the search, you could do something like: (attention, incomplete code!)

    F_TextItemsT ti;

    F_TextRangeT tr;

    F_ObjHandleT docId.

    ...

    TR = F_ApiFind (...);

    TR. Beg.offset = 0;

    TR.end.Offset = FV_OBJ_END_OFFSET;

    TI = F_ApiGetTextForRange (docId, & b, FTI_String);

    .. After that the text of the paragraph will be included in the ti TextItems structure. Navigate through this structure can be difficult and I will renounce any discussion about it for now unless you need more help. There is good information in the developer reference as to its use.

  • How can I get more results that contain the tag/bookmark appears in the awesome bar? Currently, it will show only 4.

    When I type a word in the address/url/awesome bar it's a word that I know that I used as a tag on several pages of a bookmark, only 4 results in the menu drop-down are marked pages of a bookmark. The rest of the pages in the menu drop-down are other pages available on the web. Because only 4 results are pages I tagged, the page I want to (and scoring) often does not appear. Is there a setting I can change to make it show more results? Or is there a way once I get the original results to add extra elements containing the tag / my favorites?

    It would not seem like an audio CD, as a drive in this way is a data disc when it contains mp3 files. You would need to access the file menu in iTunes, manage files here. If you manually manage music, you will need to access it as a regular folder on your computer. In iTunes, go to file > add file to library, and select individual files.
