While there's numerous QAs about inserting an image into the DB using the Data Block, how does one remove an image? Obviously there's the "UPDATE ... SET X = EMPTY_BLOB();", however, that kills the Data Block/Form's flow, and it doesn't update.
I've tried a few things:
* :CONTROL.IMG1 := NULL; (bad bind variable)
* :CONTROL.IMG1 := EMPTY_BLOB(); (some other error, probably as above)
i have multi data block filed. and checkbox field which based on control block...My task is when i check checkbox only one field should enabled and my mouse goes to that field
e.g
item11 item21 item31 chkbox1
item12 item22 item32 chkbox2
Scenario like this :
My item field based on data block and checkbox based on control block,while i checked chkbox1 , only item31 on that current record should be enabled and i changed value only on that field
when i checked chkbox1 , my cursor goes to item31...not item32
I create a simple table for image
CREATE TABLE image_table (
Design_no varchar2(10),
filename VARCHAR2(255) PRIMARY KEY,
image LONG RAW);
Then i create simple block of image_table
its show me in this website [URL] My question is i don't want to give my form path always.i want to save my picture path in my database and the name of my picture always same as my design_no column.
For example i want to save a picture in my database i will copy my picture in d:shahzaib1234.jpg now i want the path d:shahzaib save in database and when i copy my picture which path= d:shahzaib and file name = Design no its will automatically save in database.
i want to create a simple form in this form i want to upload the image on the image item with browse button that open a diaglog box that go to the image i select the image and this image is display on image item on the form.

I want to select BLOB (image) data from a table into image item of 6i form. How to do it. I am using Oracle 9i with developer6i.
View 2 Replies View RelatedI am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.
i have created on query block , upon pressing the button there is a wehre clause in the block which will filter the records based on all alike items from two tables but my problem is , in one table there is no information of struct and in other there is struct information or data, what i want is even if i pass a parameter in the where clause all the records should be filtered.
CREATE TABLE OT_ACTUAL_ACT (ITEM_CODE VARCHAR2(30),ITEM_NAME VARCHAR2(30),WO VARCHAR2(12),STRUCT VARCHAR2(12))
INSERT INTO OT_ACTUAL_ACT(ITEM_CODE,ITEM_NAME,WO,STRUCT)
VALUES ('1001','HEA100X10','300',null);
[Code]...
I am getting this
ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010
i want all the records
ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010
1003 HEA100 300
1001 HEA100X10 300

I tried below approah in DEV DB:
1. create table ABC_BAK as select * from ABC;
2. dbms_metadata.get_ddl('TABLE','ABC')
3. Removed the subpartitions details from the output of step 2 and prepared the script of create table without subpartitions
4. Drop table ABC

1. i want to create form for student's attendance.
2. for this purpose i create a form . and create 2 Data Blocks
1. Non Database Data Block (layout type: form)
2. Database Data Block (layout type: Tabular)
3. in Non Database Data Block i add 3 Items.. on the basis of i get the records from database and show them into my into my 2nd Data Block...
4. my problem is this that how can i get records from database and show them into my forms and then save thats records into my table by using Database Datablock.
i made a master-deatil data block and when i completed all field on master-data block i can`t move to data block detail.
when i press (TAB OR ENTER) on last field, the cursor go back to first field.
i want to use cursor to get data from db to "control block "(db item =no ) this data had where clause depend on item on other block
this my code :
declare
cursor get_sol is
select SOL_STEP,PROB_ID
from MI_SOLUTION
where PROB_ID=:MI_FORM_PROB.PROB_ID;
begin
go_block('control');

when am using when_validate_item trigger error raise :
FRM-40737:Illegal restricted procedure next_record in when_validate_item
that's the trigger ? or how to solve ? in case of execute query in what trigger i will write the same code to get data in case of execute query by user .
I have control block. In which user enters two values. Next is data block in which two items have property 'copy value from item' set to 'control block.item1' and 'control block.item2' resp. If thees items are made database items then in execute query will they be sent as parameters in addition to default where clause? if I check last query then query does not hv these parameters but the records returned are already filtered by control block items.
View 1 Replies View Related I wonder if there is some tiny technique to trace a duplicity on a block label without committing the records ( Maybe on Validate or new record instance)
I have one procedure to check duplicate but what I remember that there is something very smart provided from oracle to do that.

View 1 Replies View RelatedI have data that the user is modifying on the form and a data block that is supposed to reflect those change (summaries) So I created
TYPE VehicleInfo IS RECORD (Vehicle_Desc ctl_fleet_vehicles.Vehicle_Desc%Type,
Miles timecapture.miles%Type,
Hours TimeCapture.Equipment_hours%Type);
TYPE VehicleTab IS TABLE OF VehicleInfo
INDEX BY BINARY_INTEGER;
VehicleObj VehicleTab;
I fill this up with the correct data, but I would like to be able to use this as a table in the data block (called Vehicle_Summary) In the past I have piped tables into data blocks from the server, but I'm unsure how to use a table I created in forms in the Query Data Source Name of the data block.
I have two block....both are the control block.. in first block i select the date and in second block the data of that date is populated.but the data is populated using cursor in when-button-pressed trigger of that first block button.in cursor the data is selected and placed in field of detail block using into clause.... each field and one item of detail block is srno which is create in post-query of detail block using :sysyem.trigger_record.
Now i want after populated the detail block the data is sorted desc one of the field of the detail block..Can this possible using set_block_property() of block although the block is control block if yes where i should do this?
I have a form with 3 blocks in our oracle application. Block1 is a single record block. Block2 and block 3 are multi record blocks with no of records 5. Block1 and block2 are in same canvas1 of a window1. Block3 is in canvas2 of window2. There is a relation between block1 and block2. Another relation with block2 and block3 is also available.
Now my issues is while creating a record, first i entered the data in block1 (which is a single record block). Then i entered data in five rows of second block. Then i entered data in block3(multi record block) by pressing the button in block2 (each button for each row). But before saving the entire form, when i checked the data in block3 by pressing the button of first record of block2, screen shows empty.
Code in button of block2 is as follows
show_window(WIN2');
Go_block('BLOCK3');
Code in button of block3 is as follows
hide_window('WIN2');
go_block('BLOCK2');
If post; is included in block3 button. then problem we will be solved. But we don't want to use post; as it lock the table.
How to create Data Block Using Stored Procedure in Forms10G ?
View 1 Replies View RelatedI 've noticed transactional triggers, as a value for Query data block property, How can i use it, and is it really 's mode advantages than using from clause and procedure based with DMLs on non-based items?
View 3 Replies View RelatedI have a real problem with form, specifically one of its data blocks. In the order by property of the block i specify it to sort on a branch in ascending order(i tried descending as well) but for some reason the form ignores that and sorts it on the ROWNUM. I even removed the where clause, the order by clause and changed the query data source type to FROM clause and changed the data source name to pre-query. I then created the query string in the block's pre-query trigger and set query_data_source_name property to that query string and still the data in the block is not being sorted on the branch number but instead on the ROWNUM.

We are on Oracle 10.2.0.4 on Solaris 10. There is a table in my production db that has 872944 number of rows. Most of its data is now unnecessary, we need to retain, based on a date column in the table just last one month's data and delete rest of the data. So after that the table will have just 3000 rows.
However as the table was huge earlier(872k rows prior to delete) , does the delete of data release its oracle blocks and does the size of the table reduce? If not, will it rebuild the table online (online redefinition) so that the query that does a full scan on this table goes faster?
I checked using an example table that just delete of data does not remove the oracle blocks - they remain in the user_tables for that table and cost of full table scan remains same. We have a query that does the full table scan so I am thinking that after this delete I should do an online table re-definition , is that the right decision?
I have data block that has hundreds of records. On a screen I display 20 records at a time. On that same screen I have "find badge" function where user types badge/employee id and presses a button to find the record in a data block. I have no problem finding the records in a list and pointing the curser to appropriate record. My question is (which is a user request) if the badge/employee id is found to make that record to be the first record in a list.
