Oracle if updating column

The inner select does result in 53 rows, and the table being updated DOES have a primary key. @Phil The problem is that Oracle cannot guarantee that a single value will be found to set the Extended Attrs.

What matters is if you have a unique index for your "lookup" [email protected] This is a different problem entirely.You need to take a look at your view and see what parts of it can be updated.you may have to add an update trigger to the view itself. I have added a new column to an existing sales_order table to store the total value of the order. it solved my problem to some i want to know can we update multiple values at the same time using a single querry. Hello, when I try this, it gives me the following error: SQL Error: ORA-01779: cannot modify a column which maps to a non key-preserved table01779.i tried but it shows "missing right parenthesis"please send a reply to my id...thankx... 00000 - "cannot modify a column which maps to a non key-preserved table"*Cause: An attempt was made to insert or update columns of a join view which map to a non-key-preserved table.*Action: Modify the underlying base tables directly. Hi Felix, Without seeing the actual query, it's near impossible to troubleshoot. First, verify that the table you are updating has a PK.

Take a look at this example:update ( select profit_bonus, merit_bonus from employee_bonus b inner join employees e on b.employee_id = e.employee_id where e.bonus_eligible = 'N' ) t set t.profit_bonus = 0, t.merit_bonus = 0; Hi David, This time where the employee is eligible for a bonus :-)update ( select b.bonus, e.salary from employee_bonus b inner join employees e on b.employee_id = e.employee_id where e.bonus_eligible = 'Y' ) t set t.bonus = 0.1 * t.salary Hope this helps!

Also, I don't think you can update any part of the key using this method. Hi, I have a same problem while updating the table.

Unfortunately, there are some limitations with this syntax. Here is the query used in sql server but am not able to achive the same in oracle. Thanksupdate top(100) a set a.fng_calc_amt=(Is Null(b.rate_per_min, Is Null(c.rate_per_min,0))*Is Null(fng_duration,0))/60 ' from reference_tbl a left outer join SA01dbo.mea_req_1967 b on a.fng_incoming_operator = and Is Null(a.fng_npl_number_type,'Unknown') = b.moneta_cns_type and case when datepart(dw,a.fng_start_dttm_normalized)=7 or datepart(dw,a.fng_start_dttm_normalized)=1 then 'Weekend' else 'Weekday' end = b.day_type and case when a.fng_call_direction=2 then 'IN' else 'OUT' end = b.call_direction and datepart(hh,a.fng_start_dttm_normalized) = b.hour_of_day and b.mer_from_dttm=convert(datetime,convert(varchar(7), DATEADD(month,-1, GETDATE()),102)'.01',102) left outer join SA01dbo.mea_req_2000 c on Is Null(a.fng_npl_number_type,'Unknown') = c.moneta_cns_type and c.mer_from_dttm=convert(datetime,convert(varchar(7), DATEADD(month,-1, GETDATE()),102)'.01',102) where ((a.fng_exchange_id_normalized = 'ASDSSP2' or a.fng_exchange_id_normalized = 'RTDSSP2')) @dot Age If I am reading it correctly, the statement in the link you posted is different. The purpose of my statement is to only update certain records, but the condition is applied to a joined table.

great article :)i keep trying to optimize some updates of rthe last week, but I keep getting that nasty ORA-01779 error with basically everything.

I allready added a PK to the updated table, and still no luck :((my toad has just frozen trying to do something, so I can't give you the code, sorry) Hi, I've got nearly the same problem...
