Oracle if updating field

If you omit the WHERE clause, all records in the table will be updated!

oracle if updating field-3

for some reason when I try to add another zip file it did not work.

But when I added a jpg, it updated the field with JPG. Following is the working solution : DECLARE my_blob BLOB; my_bfile BFILE; my_length INTEGER; my_id INTEGER; my_bfile_offset NUMBER := 1; my_blob_offset NUMBER := 1; my_in_bfile_size NUMBER; my_in_blob_size NUMBER; bytes_rd NUMBER; bytes_wt NUMBER; BEGIN my_bfile := BFILENAME (ORACLE_DIR, 'test.zip'); UPDATE tbl_attach SET ATTACHMENT_DATA = EMPTY_BLOB() where attachment_id = 127; Commit; SELECT attachment_data INTO my_blob FROM tbl_attach WHERE attachment_id = 105 FOR UPDATE; DBMS_LOB.fileopen (my_bfile, DBMS_LOB.file_readonly); DBMS_LOB.

For instance, we have a table with a field that keeps track of which application last updated the table MYTABLE ------ ID PK APPLICATION_ID MORE_STUFF I want to write a PL/SQL trigger that requires the application to specify the appilication_id, and throw an error if the application fails to provide a value. this SQL command should fail: "UPDATE MYTABLE set MORE_STUFF = 'foo' WHERE ID = 123;" IOW, how does one determine the update list in a PL/SQL trigger? I've used the IF UPDATING construct before, but I didn't know you could specify a column. You wouldn't happen to have a pointer to some documentation to this feature, would you?

I can check to see if the value changed, but that won't do it. It's not covered in any of my Oracle Press or O'reilly PL/SQL books. I can check to see if the value changed, but that won't do it. If the record already has a non-null value for application_id, :new.application id will contain that value.

Plug-Ins allow for the Application Express framework to be readily extended with custom item types, region types, processes and Dynamic Actions.

Once defined, plug-in based components are created and maintained very much like standard Application Express components.

Now, my table of authrorised users literally just contains their username.

I'd like to expand this further to include a column containing the codes they can change to and from and then include this condition in the trigger For example: CREATE TRIGGER ...

And at the same time I can't find what's goes wrong. Hardware/OS: dedicated server 16GB RAM, i7 3.4Ghz, SATA3 HDD, Windows 2008R2. What do you mean by "How is the database laid out on the disks"?
