Populating a table using trigger

8 New Member
Hi,
I am inserting data in table1.using a trigger I want to populate TABLE2.My code is like this :
TABLE1 :ST_INFO
FIELDS : NAME (varchar),ACCOU NT_TYPE(varchar ),TIME(date)
TABLE2 :TOTALS
FIELDS : CURR_DAY(date), DISCONNECTIONS( number)
I am inserting data in ST_INFO using SQLLOADER.I want to populate TOTALS with the TIME,count of TIME field after insertion.
CREATE OR REPLACE TRIGGER TRI_TOTALS
AFTER INSERT ON ST_INFO FOR EACH ROW
BEGIN
IF(:NEW.TIME=:O LD.TIME) THEN
UPDATE TOTALS SET CURR_DAY=:OLD.T IME;
ELSE
INSERT INTO TOTALS(CURR_DAY ) VALUES(:NEW.TIM E);
END IF;
END;

With this only INSERTION operation is happening not UPDATION.
Can anybody help me ? and suggest a way to insert DISCONNECTIONS value in TABLE2.

How do I get the next int value for a column before I do an insert in MY SQL Server 2000?

I can't use the @@identity function because my application uses a connection pool and it's not garanteed that a connection won't be used

Instead of putting the same 12 columns on every table (these 12 columns contain info about who created the record and when, for example)... It may be more efficient to make a new table to hold that data. This new table would act as a universal extension table. Instead of having FKs back to any particular table, it would contain regular keys that point back to whatever table::record is its source. I was thinking of using two keys only:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
