Trigger loops and update field based on sysdate

Hi people:

I have a trigger that can update an inactive ('STATUS') field when a vaccine is after expiry date ("matching").

This is the current structure of the table:

CREATE TABLE WAREHOUSE. () VACCINE_INVENTORY

VACCINE VARCHAR2 (200 BYTE) NOT NULL,

RECEIPT_DATE DATE NOT NULL,

CONTAINER_SIZE VARCHAR2 (200 BYTE),

QUANTITY NUMBER (6, 0),

NUMBER OF REQUISITION (6, 0),

NUMBER OF FISCAL_YEAR (4, 0),

RECEIVED_BY VARCHAR2 (50 BYTE),

DATE OF CORRESPONDENTS,

LOT_NUMBER VARCHAR2 (30 BYTE) NOT NULL,

VARCHAR2 (200 BYTE) OF THE SELLER,

STATUS VARCHAR2 (10 BYTE),

NUMBER OF CATALOG_NUMBER (5, 0),

CONSTRAINT PK_VACC PRIMARY KEY (VACCINE, RECEIPT_DATE, LOT_NUMBER) USING INDEX TABLESPACE STORAGE WAREHOUSE

So the idea is that if SYSDATE > correspondents the expiration date should be changed from active to inactive.

I guess I would need to create a loop so that when the trigger is executed, it will make a loop on all records in the table and set each vaccine expired to Inactive.

I'd appreciate some help...

Thank you

Matthew

Another alternative is to simply have a SQL statement that runs once a day:

UPDATE warehouse.vaccine_inventory

SET status = 'inactive '.

WHERE the correspondents<>

AND status = 'Active';

Help me in creating a trigger Insert and Update Options
Hello

Please help me in creating a trigger.

My requirement is that, after insert or update on a Table, I want to launch an event.

I have started this way, but does not know how to fully implement it.

I have a dept table

CREATE TRIGGER DepartmentTrigger
INSERT AFTER on Dept
BEGIN
INSERT INTO mytable VALUES("123","Kiran");
END DepartmentTrigger;

Please tell me how I can put the update option also.

Thanks in advance.
Please tell me how I can put the update option also.

Add "or update". ;-)

Here are a few suggestions, but you definitely need to refer to the manual page that suggested the previous poster.

CREATE OR REPLACE the TRIGGER DepartmentTrigger
AFTER INSERT or Update ON Dept
BEGIN
INSERT INTO mytable VALUES(:new.) Dept 'DEPT ADDED OR CHANGED');
END DepartmentTrigger;

The "or replace" means that you can replace the shutter button as you develop without having to type in a drop statement each time. Just change and reissue your script over and over again until you get it right.

The addition of "update or" or "Or remove" fact the trigger too much fire for these events. Note, you peut want separate triggers in different scripts and with different names for each event. You must decide whether your design is really the same thing either an insert or an update.

: new. Dept, this is how you should refer to the vale has changed the Dept column (: old.) Dept is the previous value). I changed the double quotes in the string in the clause VALUES of apostrophes.

Loop and masking subform based on checkbox

I have a form where forms have a box in them. I need a script when the user clicks a button to hide all forms of sub who do not have the enabled checkbox. Thanks for any help you can provide.
var allChildElements;
var intNumElements;
var currentElement;
var i;
allChildElements = CRT130.nodes;
intNumElements = allChildElements.length;
for (i = 0; i < intNumElements; i ++)
{
currentElement = allChildElements.item (i);
If (currentElement.className = "checkbox")
{
if(currentElement.RawValue == 0)
{
currentElement.presence = 'hidden ';
}
}
}

Hello

className of a checkbox control is "on the ground", if you want to check if the item is a checkbox, you must Access the field in the UI to be able to check what kind of field it is.

Even if a className checkbox checkButton instead of the check box.

You must create a recursive function to traverse each subform and also each elements in the subform.

function recursiveLoop (rootObject) {}

for (var i = 0, oLen = rootObject.nodes.length; i)< olen;="">

var currentElement = rootObject.nodes.item (i);

If (currentElement.nodes.length > 0 & currentElement.className == "subform") {}

recursiveLoop (currentElement);

} ElseIf (currentElement.isPropertySpecified ("ui") & currentElement.ui.nodes.item (0) .className == "checkButton") {}

{If (currentElement.rawValue == {currentElement.getDisplayItem (1)})}

rootObject.presence = 'hidden ';

}

}

}

}

Create a script object (xfaCheckBoxes) with the function above to the breast, and then you can call the function on the click event of the button

Button1::click-(JavaScript, client)

xfaCheckBoxes.recursiveLoop (CRT10);

This should do the trick,

I hope this will help!

You want to capture update dates, with trigger on a view to refresh quickly materialized. But trigger on MV consider inserting and updates are inserts only.

I create the structure of the table like that.
create table test1 (a primary key, b (2) char number, date c, d varchar2 (10), date of e);
create table test2 (number of ab, cd (2) tank, date of the ef, gh varchar2 (10), date of the ij, kl varchar2 (100));
Create materialized view log on test1;
create materialized view fast refresh test1_v on commit in select * from test1;
I have create a trigger of the sample
CREATE OR REPLACE TRIGGER test1_trig
AFTER INSERT OR UPDATE OR DELETE
ON test1_v
FOR EACH LINE
DECLARE
lr_test2 test2% ROWTYPE;
lv_error VARCHAR2 (4000);
BEGIN
lr_test2. AB: =: NEW.a;
lr_test2. CD: =: NEW.b;
lr_test2. GH: =: NEW.d;
IF THE INSERTION
THEN
lr_test2. EF: = SYSDATE;
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'INSERT ';
INSERT INTO test2
VALUES lr_test2;
ELSIF UPDATE
THEN
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'UPDATE ';
UPDATE test2 = lr_test2 ab WHERE = LINE: OLD.a;
ELSIF REMOVAL
THEN
DELETE FROM test2
AB = WHERE: old.a;
END IF;
EXCEPTION
WHILE OTHERS
THEN
lv_error: = SQLERRM;
INSERT INTO XXDOMINO_FG_DATA_LOAD_ERROR
VALUES ('test1_trig',
: OLD.a,.
"test1_trig,"
LV_ERROR,
SYSDATE);
COMMIT;
END test1_trig;
/
So, if check you my code,.
When I insert EF = SYSDATE, IJ = SYSDATE.
Update EF is not changed, IJ = SYSDATE.
So I like to capture their insertion and update dates.
But if updates or insert arrives on the materialized table. The trigger themselves as an INSERT only.
So how do you capture the updates?

I use the statemnet with out merger with performance and also able to capture the update dates.

CREATE OR REPLACE TRIGGER test1_trig_merge

AFTER INSERT OR UPDATE OR DELETE

ON test1_v

FOR EACH LINE

DECLARE

lr_test2 test2% ROWTYPE;

lv_error VARCHAR2 (4000);

BEGIN

IF THE REMOVAL

THEN

DELETE FROM test2

AB = WHERE: old.a;

ELSIF INSERTION

THEN

MERGE INTO test2 one

B using (SELECT 1 FROM DUAL)

WE (ab =: new.a)

WHEN MATCHED

THEN

UPDATE the VALUE ab =: NEW.a.

CD =: NEW.b,

GH =: NEW.c

IJ = SYSDATE,

KL = "Update"

AB WHERE =: old.a

WHEN NOT MATCHED

THEN

INSERTING VALUES (: NEW.a,)

: NEW.b,.

: NEW.c.

: NEW.d,.

: NEW.e,.

"INSERT");

END IF;

EXCEPTION

WHILE OTHERS

THEN

lv_error: = SQLERRM;

INSERT INTO XXDOMINO_FG_DATA_LOAD_ERROR

VALUES ('test1_trig',

: OLD.a,.

"test1_trig,"

LV_ERROR,

SYSDATE);

END test1_trig_merge;
