SQL & PL/SQL :: Get Old Value Of Column In Update Statement
Sep 17, 2007While updating a table, is it possible to get the old value of a column. I need to get it inside a PLSQL block and not in a trigger.for example :-
DECLARE
l_amountNUMBER(5) := 0;
BEGIN
UPDATECustTransactions
SETamount = 150
WHEREcust_id = 5412
RETURNING amount INTO l_amount;
DBMS_OUTPUT.PUT_LINE ( 'l_amount= ' || l_amount );
END;
By using the RETURNING clause i am getting the new updated value. I need the old value for some processing. Do i have to explicitly query it before the update stmt? Pls reply.

View 2 Replies View RelatedDoes Update On A Partitioned Column Cause Fragmentation
Apr 11, 2008Does "Update on a Partitioned Column" cause fragmentation ?
See example below :
Suppose I have a table as below that has approx 3 million rows and growing :
1) Table ABC :
file_id number
status_flag varchar2(1)
file_Content clob
date_created date
2) This table is list partitioned on Column "status_flag".
Column "status_flag" can take 3 values "A" or "B" or "C"
3) A file_id can transition from 1 "Status_flag" to another. [ A--> B , C--> B, B-->C, A --> C, etc ]
This means its possible to UPDATE the "status_flag " - the partitioned column.
Question :
-------------
1) Would the movement of rows from 1 partition to another cause fragmentation ?
2) Or Instead, should this be achieved by maintaining 3 tables - 1 each for every "status_Flag" as Table_A, Table_B, Table_C
This would mean that, if file_id 1, changes "status_flag" from 'A' to 'B' :
-- The corresponding row from Table_A will be created in Table_B
--- The same will be deleted from Table_A
This would still cause fragmentation ... with the overhead of Inserting a CLOB column from 1 table to another.
3) How to determine how much percent of the table is fragmented ?
SQL & PL/SQL :: Update When ID Column Is Matched / But One Of Others Columns Not
Mar 12, 2013my need is to perform merge - update when id column is matched, but one of others columns not.When id column is not matched then I perform insert.

SQL & PL/SQL :: Update Clob Column Using Execute Immediate?
Aug 30, 2010I am encountering an error message while updating a xmltype column using dynamic sql statement. I am using dynamic sql here as the table is not placed in the same schema from where the plsql procedure is invoked. The schema name is passed to the procedure as an argument. I am using below pseudo code for this purpose.
Create procedure myproc(p_schemaname varchar2, p_id number)
is
p_clob clob;
p_str varchar2(2000);
begin
[code]...
This is throwing an error 'missing expression' at the line of 'exeute immediate'.
But it works if I run a static sql update by hard coding the schema name in the statement.
