Reading values from a dynamic report.

Question

Hi All.
I have an interactive report. It has built by a SQL query, the report has 6 columns, two of them have been dynamic created. Source Lines for this fields are as follow :
select
apex_item.checkbox(1,TRANSACTION_INTERFACE_ID) ,
apex_item.display_and_save(2,INVENTORY_ITEM_ID),
field 3,
field4,
from tables
Output example
transaction_id
(CheckBox) / ITEM_ID / Locator_ID / field4
1200 787 0 1616161
1201 788 7373 1616161
1202 789 0 1616161
1203 790 2625 1616161
The report looks fine, I tried giving some functionality, I added a submit button, that it has an update process :
DECLARE
l_count number;
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.count
LOOP
l_count := l_count + 1;
UPDATE TABLE SET STATUS = '1'
WHERE TRANSACTION_INTERFACE_ID = APEX_APPLICATION.G_F01(i)
AND TRANSACTION_TYPE_ID = 161;
UPDATE TABLE SET LOCATOR_ID = APPS.APEX_GET_LOCATOR_ID (to_number(APEX_APPLICATION.G_F02(APEX_APPLICATION.G_F01(i) ) ) )
WHERE TRANSACTION_INTERFACE_ID = APEX_APPLICATION.G_F01(i)
AND TRANSACTION_TYPE_ID = 112;
END LOOP;
:P_REC_COUNTER := l_count;
END;
The logical for this process is update certain fields for a specific table.
Case1.- update the status field for all the record selected. (This works perfectly using just the first update segment code) G_F01
Case2.- update the locator_id for all records selected. this location should be gotten by a function (APEX_GET_LOCATOR_ID (ITEM_ID)) that pass an IN-variable ITEM_ID. Is this case which is the one is giving me troubles, to read the value for ITEM_ID from the PLSQL variable G_F02 for the record selected, as you see I've been trying to get this value without success for this case.
Also I've been trying to get the number of rows selected to show it in the update message. I created a variable to hold this value and then pass it the value to an hidden ITEM but this is always Null. I know that there is another way to get the number of records. Actually I've read some blogs regarding this arrays but I've been trying to use but I couldn´t make this works.
Any advices really will be appreciated
Thanks in Advance.

Answer 1

Lets say your internal table name for table control is t_stock and table control name is tc_material.
in the PAI of Screen you would have something like this:
LOOP AT T_STOCK.
FIELD .......
*Insert a module here.
MODULE UPDATE_VALUES_TO_IT.
ENDLOOP.
and in the Module UPDATE_VALUES_TO_IT you should code .....
modify t_stock from wa_stock index tc_material-current_line.
hope this would help u.
