Help in Update Statement

Hello everyone..

I need help here in Writing this update statement on a Column 'emailaddr_'. One of our Clients have changed their emai Domain from say abc.com to xyz.com. I need to update all the Rows that abc.com to xyz.com.


For eg.

Source Table Column
--------------------
[email protected]
[email protected]


target Table
------------
[email protected]
[email protected]


I have like 950 Records whose email domain needs to be changed.

Can anyone help me here in Writing a sq ?..

Any help is appreciated

Look at the REPLACE function in sql. :rolleyes:

UPDATE table_name set column_name=replace(column_name,'abc.com','xyz.com')

Assuming that abc.com comes only as the domain name.

HTH.

And that there isn't a domain with fred_abc.com
Try
UPDATE table_name set column_name=replace(column_name,'@abc.com','@xyz.com')
where substr(column_name,-1*length(@abc.com')) ='@abc.com'

thanks a lot guys....appreciate it.

I think that is the same thing as

WHERE column_name LIKE '%@abc.com'

The LIKE should be fine in this context.
Generally, I prefer to use an equals because there's the potential for the contents of a variable to include LIKE wildcard characters (_ and %) which can confuse the result
EG
SELECT * from table(sys.dbms_debug_vc2coll ('@test.com','@tast.com','@t_st.com'))
where column_value like '%@t_st.com'

However, I did a quck check and these characters shouldn't be in the domain name so the issue should not arise
