Adding Column If It Does Not Exist?

Mar 31, 2010

I've been trying to write some code to add a column if it does not exist as the code will be run numerous times and will be parameterized in other software to run across multiple tables.

Here is what I have made so far:

DECLARE
COLEXISTS integer;
vCmdStr varchar2(4000);

[Code]....

I can't figure out where the invalid character is.

SQL & PL/SQL :: Adding Audit Column To Track Delete And Update

May 15, 2012

we received a design advise to add columns to track the update and delete done on each row in our tables:

- DELETED_DATE_TIME
- DELETED_BY
- UPDATE_DATE_TIME
- UPDATED_BY

In our architecture, the application can only access functions/procedures to access/modify data. Each function logs the action, the executed sql statement, oracle error, user terminal, and the user into a unified log table by using v$ tables to create a general log function that is called after execution or error.

The only advantage is that it will be easier to know the delete and last update information faster versus space and design modification.

SQL & PL/SQL :: Updating Column In Every Row Except For The First

Jan 16, 2012

I am trying to find a way to update all of the rows in a table for a column EXCEPT for the very first row. I am not sure if this can be done while I enter my SET parameter or not. I have also thought about using an EXCEPTION in a stored procedure. For example, say I have the table listed below:

SQL> select * from example1;

CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ---------------
A 100 A 200 John 20111225
A 100 A 300 John 20111225
A 100 A 500 John 20111225
A 100 A 400 John 20111225
A 100 A 250 John 20111225
A 100 A 700 John 20111225
A 100 A 800 John 20111225
A 100 A 900 John 20111225
A 100 A 1000 John 20111225
A 100 A 1150 John 20111225
A 100 A 1275 John 20111225
A 100 A 3000 John 20111225

12 rows selected

I am wanting to update the table so that if there were more than 3 J_id's on the table for the same I_id then it will set all of the code1's and code2's to a C except for the very first one. Such as:

SQL> select * from example2;

CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ----------------
A 100 A 200 John 20111225
C 100 C 300 John 20111225
C 100 C 500 John 20111225
C 100 C 400 John 20111225
C 100 C 250 John 20111225
C 100 C 700 John 20111225
C 100 C 800 John 20111225
C 100 C 900 John 20111225
C 100 C 1000 John 20111225
C 100 C 1150 John 20111225
C 100 C 1275 John 20111225
C 100 C 3000 John 20111225

12 rows selected

I have done some searches and haven't seen any results.

PL/SQL :: Is Updating A Non-indexed Column Slower

Oct 7, 2013

I have learnt that indexes slow down the DML operations. My question is specific to an update statement. Is it going to be slower if Im trying to update an indexed column on my table or it is slower overall (even when a non-indexed column is getting updated in the table) How does it behave in case of inserts & delete operation.

Above query is working fine to retrieve the previous column values.But when we are updating the SUM_PRE_COLS column with those values it's not working fine.

I tried by using the following query

PL/SQL :: Updating A Column Randomly With Selected Values?

Sep 26, 2013

We've an accounts table that basically represents hotel chains & brands. an example shown below.

account_id chain_id brand_id service1
NULL     NULL          111
NULL     NULL          122
NULL     NULL           11

Here I want to update the chain_id & brand_id which are currently NULL in order to make every row eligible for further processing.

There is another table(say chain_brand) which maintains the relationship between chain_id and brand_id. one chain_id can have multiple brand_ids eg.,

chain_id brand_id
101     2011          101
2012          102     2020

Now I need a script that could randomly pick values from chain_brand table and update the accounts table. condition is those values should be unique for an account_id eg.,

account_id chain_id brand_id service1
101          2011     111               101
2011     122               102          2020     11

so each account can be attached to only one chain_id and one brand_id.

Forms :: ORA-01461 When Updating A LONG-Column Via Trigger

Jul 5, 2010

I have a non-base-table item which I want to update in the pre-update trigger of the current block.

If the content of the field exceeds 4000 characters, i get the error message

ORA-01461: can bind a LONG value only for insert into a LONG column.

The code is

update tab set long_col = :formsblock.long_col
where tab.tabpk = :formsblock.foreign_tabpk;

Workarounds would be,
1.) to delete the old dataset and insert the new one:

delete from tab
where tab.tabpk = :formsblock.tabpk;

insert into tab (tabpk, long_col) values
(:formsblock.foreign_tabpk, :formsblock.long_col);

or 2.) to change the Item from a non-database item to a database item and use the internal update of the forms-module, but both workarounds are not very satisfying.

Do you know another way to update the LONG-column within the pre-update trigger (or any other PL/SQL part of forms)?

SQL & PL/SQL :: Adding High And Low To Zip Plus Four Values?

Jan 19, 2011

I have a table with zip codes and their plus four values. For ex: zip code of 10000, which has corresponding plus four values of 001, 002, 003, and 008, 009, 010. The issue is just that--a zip code can have sequential plus four values, and then it will skip several potential plus four values, and then start again. I would like to assign a low plus 4 value and high plus four value to a zip code, keeping in mind that the plus four values are not always sequential. So, it would be similar to this:

zip plus4 low plus4 high
10000 001 003
10000 008 010
