I am using developer 10.1.2.0.2 I have created a table to store the BLOB, which is jpg image originally. And I have uploaded those image into the database successfully.
Table name: images
img_id number
img blob
I know that I can set display one image each time if I create the image icon on the form using "data block wizard"..But the problem is that I cannot display multiple image on a form at the same time
I have a table containing records with a field representing a png image that is encoded as base64 text. The procedure responsible for creating the record receives the base64 information in a parameter of type CLOB. It then inserts it in a field of same type on the record. I want to transform the CLOB data into an image and display it back on the form.

FRM-40364: The data type of item 'ProductImage' does not match the corresponding column in the stored procedure.
I try to change 'myImage PRODUCT.ProductImage%TYPE' -> 'myImage BLOB' in my package but still get that error.

View 6 Replies View RelatedWe have apex application with one record report that shows image.We use database procedure to show image.And call it in apex like:
'<img src="show_image?p_id=' || NVL(dp.id, 0) || '" height="200" width="200" />' as image
But the image is not shown. We only see broken image icon.With right click on broken icon, we can save it and it's actual image we want to display.
If we call procedure like: URL.....
If we use the same procedure on another table with images which are smaller, then the image is shown.Minimum image length in table A is (DBMS_ LOB.getlength (file)): 105243..Maximum image length in table B is: 1702. URL....

i want to save mathematical equations / symbols. using forms 6i.
What characterset , font to be used.
(note, my client has equations written in MS Word 2007)
i am using form6i & oracle 8i.
i have master -detail form. both are database blocks.
i have inserted values for the master block bt not for the detail record my problem is.. "user should not be allowed" to move to next record of the master block before saving the current record
im now doin' my currently program, actually they requesting for an update. I added birth date column in the module,they asked to the request to put a validation on date, such as:
a. under age
b. :txt_ph_birthdate > SYSDATE
c. if :txt_plan_type = 212 then
17 yrs, 5 mos and 29 days and 40 yrs, 5 mos and 29 day - as validation
d. if :txt_plan_type = 214 then
40 yrs and 6 mos and 55 yrs, 5 mos and 29 days - as validation
e. if :txt_plan_type = 215 then
17 yrs, 5 mos and 29 days and above - as validation
they also instructed me to put the validations in birth date after the column of birthdate, which is the :txt_plan_type(list_item) and i put it in TRIGGER (when-validate-item)after i did the codes and compile it., theres no message for error but i think its not working..it working. i already updates also the insert and the other trigger and procedure, i just add the plan type on it.
i havent edit the save button because the as i read the codes the it just call the procedure that i edit.when i run the program and after i encode the data..and when i press the save button, nothing happens or any confirmation.in addition, why is it that my validation on age doesnt work?
heres the
declare
n_months_between NUMBER;
d_same_day_occur DATE;
n_years NUMBER;

I have used a template to create a form which has 3 below tables / blocks in the form:
1.'OIFC_INV_DEVICE_TYPES'
2.'OIFC_INV_SECTIONS'

The 1st 2 tables are used only to fetch values through a LOV and no insert happen during save and the 3rd has initial values defined and has to insert these values while click on the save (when button pressed trigger) button which has the below pasted code, but no error is thrown and neither the record is inserted,

I have a form with 2 datablocks, datablock 1 is the datablock in which I want to write data too that table within the database.
datablock 1(which i want to insert data too) is:
In forms layout this simply consist of a display box at the top of the screen which is populated by a LOV from another table within the database. The lov value selected will then be placed in the appropriate field of the table. For example the LOV contains a list of every single car make there is. i.e. Renault, Ford, Vauxhall etc
datablock 2 (in which i just want to read data from, and write the data to the table used in datablock1) is:
Below this is my second datablock, which on the trigger 'on-new-form-instance' reads data from an already existing table and displays a list of every single make of car ie, focus, clio, megane, astra etc (tabular layout displaying 12 records at a time). Beside these car models will be a checkbox which is a non database item, originally unticked.
What I want to do is the user selects a car type from the top LOV say Renault for example, then they will go down the list of car models checking each and every model of car Renault makes, i.e clio, megane, etc when these models are all checked, and the user clicks save, it will insert into my table (which is the top datablock) the car which was selected From the LOV at the top, plus each and every car model which has a checkbox checked. So for example, say the user selects Renault from the top LOV and checks models clio, megane, laguna. There should be 3 entries in the table consisting of:
Renault, clio
Renault, Megane
Renault, Laguna
Now I have got it to work partially, in the fact that if I load the screen, select my car type and then multiple models that it will add 1 car type and model to the database but not the others which I have checked. I think I need it to go down each row and check if the value is ticked or something like that? using row id or something?
Here is the code I have so far: Just so you know car_model is the name of my table used as my second datablock, contains all car models as u would expect.
BEGIN
if :model_chkbox = 'Y'THEN
v_model_id := :car_model.id;
INSERT INTO NOTE_ACCESS_DEFAULT (car_type, model_id)
VALUES (:car_type, v_model_id);
end if;
EXCEPTION
WHEN OTHERS THEN
MESSAGE('SQLERRM: ' || SQLERRM);
END;
Another option was to do a loop and go through each record and see if it is checked, not sure how I would implement this but it does seem like a very inefficient way to do such a task, perhaps it would be something to do with when a checkbox is ticked stamp it or something.
