Oracle updating - donna barnes life and dating coach

Regards, Amit Hi, I understood the usage of with clause now referring this case, but here my "Set" statement is using a constant value of 100.

Since my table is too huge and update will be on many rows(some cases upto millions) I face severe bad performance.

Hence I am trying to use a WITH clause during update but I'm hitting error in it.

Can you advise the solution or any alternative way to do this: WITH x AS (SELECT rowid,case when count(distinct leg_division)over(partition by leg_distributor_vendor) = 1 THEN NULL ELSE sap_division end FROM sap_x_tt_agreement_ss1 WHERE dep_error_code IS NULL AND val_error_code IS NULL) UPDATE sap_x_tt_agreement_ss1 y,x SET sap_division = NULL WHERE x.rowid = y.rowid; select * from v$version; Error: ORA-00928: missing SELECT keyword Do let me know if test script is required.

So as an alternative that doesn't have any GTK dependencies and comes with automatic updates too, I've set up an Ubuntu PPA for the latest Oracle Java 7 (JDK).

The PPA should work not only with Ubuntu but also Linux Mint and other Ubuntu-based Linux distributions.

--------------------------------------------------------------------------- We've previously written about installing Oracle JDK 7 in Ubuntu using a script with a GUI provided by Zenity.

Some may find this method hard to use and also, it comes with GTK dependencies.

So if that temp result of yours is large, thats going to be very expensive.

So you might be better off loading your own temp table and using that as a source.

Option2: update t x set object_id = (SELECT dense_Rank() over(partition by object_type order by object_name,created) FROM t y where owner = 'SAPMIG' and x.rowid = y.rowid); Option3: update t x set object_id = (SELECT dense_Rank() over(partition by object_type order by object_name,created) FROM t y where owner = 'SAPMIG' and x.rowid = y.rowid) where exists (SELECT 'x' FROM t y where owner = 'SAPMIG' and x.rowid = y.rowid) Hi, I understood the usage of with clause now referring this case, but here my "Set" statement is using a constant value of 100.

The current JDK version in the PPA is Oracle Java 7 Update 76 (7u76).

    The room was spotlessly clean and the bed was totally comfortable. I could hear all the staff were helping everyone they came into contact with.
