Deleting from a table based on values in a second table

Is it possible to DELETE from (or for that matter do an UPDATE to) a table based on values in another table? I have gone through the online documentation but can't seem to find anything. I'm trying to delete rows from table A where A.field1 = B.field1 and B.field2 = 'X'. (B being the second table)

It is done using subqueries in the where clause.
delete from A
where A.field1 in (select B.field1 from B where B.field2 = 'X');
delete from A
where exists (select 'x' from B where B.field1 = A.field1 and B.field2 = 'X');
delete from A
where A.rowid in (select A.ROWID from from A, B where B.field1 = A.field1 and B.field2 = 'X');
And many other varieties. Eg. more specialised:
delete from A
where A.txdate < (select B.prune_date FROM B where B.field1 = A.field1 and B.field2 = 'X')
and A.txstate in (select S.txstate from S where S.prodlass=a.prodclass and s.deletable='Y');

How to exclude records from one table that is contained in a second table

I am trying to create a Crystal report that excludes records from one Table that is contained in a second table using the != link option and it is not working. I've tried all of the different enforce options, and it is still not excluding those records. Does anyone have any suggestions of what I'm doing wrong or any other suggestions how I can obtain the results I need?

Deleting rows from table based on value from other table

Hello Members,
I am struck to solve the issue said below using query. Would appreciate any suggestions...
I have two tables having same structures. I want to delete the rows from TableA ( master table ) with the values from TableB ( subset of TableA). The idea is to remove the duplicate values from tableA. The data to be removed are present in TableB. Catch here is TableB holds one row less than TableA, for example
Table A
Name Value
Test 1
Test 1
Test 1
Hello 2
Good 3
TableB
Name Value
Test 1
Test 1
The goal here is to remove the two entries from TableB ('Test') from TableA, finally leaving TableA as
Table A
Name Value
Test 1
Hello 2
Good 3
I tried below queries
1. delete from TestA a where rowid = any (select rowid from TESTA b where b.Name = a.Name and a.Name in ( select Name from TestB ));
Any suggestions..
We need TableB. The problem I mentioned above is part of process. TableB contains the duplicate values which should be deleted from TableA. So that we know what all values we have deleted from TableA. On deleted TableA if I later insert the value from TableB I should be getting the original TableA...
Thanks in advance

Select from different tables based on value

Hi Forum,
I'm stuggling with a problem:
In a table, I have two columns, pref_type and pref_value. Column pref_type stores a number value that is linked to a preference type, whereas column pref_value stores the value of that preference.
Unfortunately, the data model is such that per preference type a different tables needs to be used, so for example, if
pref_type = 1, table to query is A, whereas if
pref_type = 2, table to query is B.
I now want to write a query that resolves the preferences, ie it should branch to the respective table based on pref_type and search for pref_value and deliver back a different column of that respective table.
My first approach was like that:
select decode (pref_value, 1, (select result from A where pref_value = ???),
2, (select result from B where pref_value = ???)
where the three ??? depict the problem I'm having, as Oracle doesn't allow me to have a harmonized subquery here.
How do I achieve this?
Thanks for any help,
J. Sieben

I believe this is what you are trying to get at:
SELECT DECODE(m.pref_type, 1, (SELECT result FROM a
                               WHERE a.pref_value = m.pref_value),
                           2, (SELECT result FROM b
                               WHERE b.pref_value = m.pref_value)
FROM my_table mAlthough, if the tables are large, that might be pretty slow. Better than an outer join, but one of those correlated queries is going to be run for each row in my_table. You could lso try something like:
SELECT m.pref_type, r.result
FROM my_table m,
     (SELECT 'A' tbl, pref_value, result
      FROM a
      UNION ALL
      SELECT 'B', pref_value, result
      FROM b) r
WHERE DECODE(m.pref_type, 1, 'A', 'B') = r.tbl and
      m.pref_value = r.pref_valueHTH

Update table based on values from other table

Hi,
I am trying to update one table based on the values of another table. Since you can't use From in update statements, how do you execute this?
For example i have to tables, Table A and Table B. I want to update a column or columns in Table A based on another value in Table B:
So if the column in Table B was 1 then column in Table A would be Yes, if Table B was 2, then Table A would be Yes, if Table B was 3 then Table A would be N/A and so on...
Any help would be appreciated.
thanks,

Update 1 column,1 single table based on where results of multiple tables

I would like the my_id column in 1 table updated to the static value of 247 for my_id stored in the 1 single table based on the where clause, which uses the my_id column in it.
The update statement updates all rows in table1, instead of just the rows where
the condition ( (b.my_id=a.my_id)
and ( b.my_name like 'OIS SrClerk%')
and (a.f_id=m.f_id)
and (trunc(m.cr_time) < '02-Apr-2008')) is true
What needs to be changed?
update table1 a
set a.my_id=247
from table1 a, table2 b, table3 m
where
(b.my_id=a.my_id)
and ( b.my_name like 'OIS SrClerk%')
and (a.f_id=m.f_id)
and (trunc(m.cr_time) < '02-Apr-2008')

Are you looking for this?
UPDATE table1 A
   SET A.my_id = 247
WHERE EXISTS (SELECT 'x'
                 FROM table2 b,
                      table3 M
                WHERE b.my_id = A.my_id
                 AND b.my_name LIKE 'OIS SrClerk%'
                 AND A.f_id = M.f_id
                 AND TRUNC (M.cr_time) < to_date('02-apr-2008 00:00:00','dd-mon-yyyy HH:MI:SS') )changed date string to to_date

Creating a Detail Table Based on an Action in Another Table or Matrix to Display in the Same Report (Not a Drill-Through)

Hello,
I was wondering if it's possible have a matrix which shows total credits by month and have drill-down groupings to display the invoice numbers for each credit. Then, once the drill-down is expanded for a particular month, be able to click on the invoice
number and have another table under the matrix display the details of the invoice.
I don't really want a drill-through because that opens a different report in the window, what I want to be able to do is stay on the main report. I also don't want to drill-into the invoice details from the matrix as that expands the matrix out and
makes it unruly and ugly. I've been playing with subreports but not able to get what I want out of it.
I hope this makes sense - is there a way to do this in SSRS?
Thanks!!

Hi AvenueStuart,
After testing the issue in my environment, we can refer to the steps below to work around the issue:
Create a new table with the details of the invoice under the matrix.
Add a parameter named invoice which get available values from the invoice field in the dataset.
Right-click the [Sum(invoice)] cell to add an action with “Go to report” option, and specify the same report with the parameter below:
Name: invoice
Value: [invoice]
Right-click the table to add a filter in the table:
Expression: [invoice]
Operator: =
Value: [@invoice]
If there are any misunderstanding, please elaborate the issue for further investigation.
Thanks,

Using JOIN to two tables to find records NOT in second table...

I always seem to get these types of queries wrong and need a bit of help:
I have a table of relationships called MARKETER_ACCOUNT and another table of pending relationships called ACCOUNT_ENROLLMENT.
I have accounts that can be enrolled with a MARKETER. They enter the ACCOUNT_ENROLLMENT table as Pending and on a certain Effective Date the go active and then move to the MARKETER_ACCOUNT table. If a relationship ends, it can end by either enrolling with another Marketer or if no pending enrollment they are assumed to be going back to the parent company.
So I want to find all the records that came back to the parent company (i.e. they should not have a pending record in the ACCOUNT_ENROLLMENT table but have an end date in the MARKETER_ACCOUNT table:
Select * from MARKETER_ACCOUNT M
where M.account_no NOT IN (select E.account_no from ACCOUNT_ENROLLMENT E
where E.effective_date between '08-DEC-2009' and '07-JAN-2010')
and M.expiration_date between '08-DEC-2009' and '07-JAN-2010';
This query is still running and I'm not sure where I am going wrong. I want to say GIVE me all the accounts in the MARKETER_ACCOUNT table that have an expiration date between '12/07/2009' and '01/07/2010' and where those accounts are NOT pending in the ACCOUNT_ENROLLMENT table where the effective date is for the same period.
Any help would be greatly appreciated.
Sean

You could possibly try the NOT EXISTS version of the query:
SELECT *
FROM    MARKETER_ACCOUNT M
WHERE   NOT EXISTS
                SELECT NULL
                FROM    ACCOUNT_ENROLLMENT E
                WHERE   M.ACCOUNT_NO = E.ACCOUNT_NO
                AND     E.EFFECTIVE_DATE BETWEEN TO_DATE('08-DEC-2009','DD-MON-YYYY') AND TO_DATE('07-JAN-2010','DD-MON-YYYY')
AND     M.EXPIRATION_DATE BETWEEN TO_DATE('08-DEC-2009','DD-MON-YYYY') AND TO_DATE('07-JAN-2010','DD-MON-YYYY');Otherwise check out these threads:

Deriving 1 Value from 2 Fields Based on Values in Fields

I have a query that needs to return 1 of my values based on the values from 2 fields from 2 tables. However, the value should only be returned in 1 field and one of the fields should be evaluated first. If this first evaluated field has a certain value ('Y') then the other field is ignored.
To be more clear, per the normal query below, what I want is to somehow, if possible, combine the case t2.el_contr and case t1.contr_type statements so that one field, say: mbr_contr_type_desc returns a value.
So that if the value of t2.el_contr is 'Y' then 'SUB CHILD' is returned. It is important that this field should be evaluated first (If the value of it is 'Y' then the other field evaluation can be ignored). If this is not 'Y', then t1.contr_type should be evaluated and the values as listed below also returned to mbr_contr_type_desc.
I know the following isn't correct, but it might better illustrate what I'm trying to do (the normal query is below this)
case t2.el_contr
when 'Y' then 'SUB CHILD'
case t1.contr_type
when 'A' then '1 PARTY MALE SUB'
when 'B' then '1 PARTY FEMALE SUB'
when 'C' then '2 PARTY MALE SUB'
when 'D' then '2 PARTY FEMALE SUB'
when 'F' then 'FAMILY MALE SUB'
when 'G' then 'FAMILY FEMALE SUB'
end as mbr_contr_type_desc
In an Access query I would do the following in a column:
iif([el_contr]='Y',"SUB CHILD',SWITCH([contr_type]="A","1 PARTY MALE SUB",[contr_type]="B" etc.))
*NORMAL QUERY*
select t1.ssn
t1.type,
t1.grp_id,
t1.contr_type,
t2.el_contr,
case t2.el_contr
when 'Y' then 'SUB CHILD'
end as mbr_contr_type_desc_2,
case t1.contr_type
when 'A' then '1 PARTY MALE SUB'
when 'B' then '1 PARTY FEMALE SUB'
when 'C' then '2 PARTY MALE SUB'
when 'D' then '2 PARTY FEMALE SUB'
when 'F' then 'FAMILY MALE SUB'
when 'G' then 'FAMILY FEMALE SUB'
end as mbr_contr_type_desc_1
from member_elig t1
inner join grp_master t2 on
t1.grp_id = t2.grp_id

Perfect!
Thanks, didn't know that existed. Still learning my way around pl/sql..
One other (unrelated) question..when i hit the CTRL+LEFT ARROW* button in my SQL window, it will not tab back. This is really annoying! I have looked through PREFERENCES-EDITOR and can't seem to find any setting that will allow this. Do you know of any way to change this so I can tab backwards/fowards through code in the SQL window?
Thanks for any suggestions!

Calling functions and inserting tables based on values entered

Hello Everyone,
I am creating a function as below:
create or replace function func(flags in number,Ctry in varchar2) return number
is
maxv number;
flagv number;
begin
flagv:=1;
select max(num) into maxv from A;
if flags =1 then
insert into A(num,nam) values(maxv+1,Upper(Ctry));
else
flagv:=0;
end if;
return flagv;
end;
The function takes two parameters-The first one will be either 0 or 1.The second one will be name of a country.
If the first parameter is 1 then we would insert the country name passed, to the table name A.If its 0 then no insertion occurs and the function would return a value 0.
On compiling the function I get a success!.
When I do a
SQL>select distinct func(0,'UK') from B;
it works well and returns 0
However when I do
SQL>select distinct func(1,'UK') from B;
I expect an output of 1 & also expect UK to be inserted as anew row in the table A.However It throws an error saying "ORA-14551: cannot perform a DML operation inside a query .."
It is very important for me to use select to call the function, as my application would fire a select with that function and based on the value entered would insert or not insert at the back end.
Is there any way out to do this??
variable temps number
exec :number :=func(1,'UK');
does work but I cant use this in my application.
Hope you can help! Thanks!

create or replace function func(flags in number,Ctry in varchar2) return number
is
PRAGMA AUTONOMOUS_TRANSACTION;
maxv number;
flagv number;
begin
flagv:=1;
select max(num) into maxv from A;
if flags =1 then
insert into A(num,nam) values(maxv+1,Upper(Ctry));
COMMIT;
else
flagv:=0;
end if;
return flagv;
end;
Is the above changes in BOLD enough or I need to do something else too in order to incorporate the autonomous transaction??
I am not too familiar with autonomous transaction.Could you please suggest the changes I need if any more required??
Thanks a ton for your suggestions!

3. If the TABLE2.MNS_STATUS is 5 then set TABLE1.INCIDENTSTATUS='Acls' for all TABLE1.INCIDENT = TABLE2.TKT_NBR

For point 3 and 4 use decode. and dont forget to use EXISTS in your update.
UPDATE table1
   SET (severity,
        escalation,
        incidentstatus) = (SELECT svrt_cd,
                            escl_lvl,

                      WHERE TO_NUMBER(table1.incident) = TABLE2.TKT_NBR)
WHERE EXISTS (SELECT NULL

Execute process chain step based on value in a custom table

HI,
I have a requirement where i need to execute a process chain step based in the value of a field in a custom table.
e.g. If ztable-zflag = 'X' then execute next step else stop.
I am trying to use the decision between multiple alternatives process type, but i guess we can only use formulas in it.
Also, i created a custom method and called it through the badi RSAR_CONNECTOR, but the same isnt working as expected.
Would appreciate inputs from the experts.

Hi,
Thank you for your response.
I followed exactly what is written in the document. But when I execute the process chain with the Decision between Multiple Alternatives process type, it fails with an exception message.
Below is what I have done:
Below is the code that I entered in the method (Please note that ZPC_CONTROL is the table from which I need to check the value. This table contains 2 fields: Process Chain Name and Flag. My requirement is that when a particular process chain has the flag checked, then the process chain should move ahead):
Below is the GET method:
Finally, here is the formula that I have written in the Decision Between Multiple Alternatives process type:
And the event is Option 2 (which I assume will move the process chain forward if the flag is checked for the process chain ‘TEMP_TEST’)
Please note that the flag for process chain ‘TEMP_TEST’ is checked in the table ZPC_CONTROL.
Below is the error in the process chain:
Please let me know where am I going wrong here. Appreciate your help.

Update vs Merge - Updating one table based on values in another

Hello
I have two tables lets say TAB_A and TAB_B. I altered table B to include a new column from table A
I wrote a merge statement as follows to merge the data
MERGE INTO TAB_A
USING TAB_B
ON (TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)
WHEN MATCHED THEN
UPDATE SET TAB_A.PPYACCOUNT=TAB_B.PPYACCOUNT;
I know INSERT is for inserting new records
UPDATE to my knowledge is to modify currently existing records (loosely)
MERGE is one I rarely used, until this particular scenario.
The code works perfectly fine, but I was wondering how could I write an update statement? Or in this scenario should I even be using an update statement?

The MERGE is good and performs well, although it malfunctions (sometimes updating data wrongly) if the destination is a view with INSTEAD OF triggers.
The UPDATE with similar performance to the MERGE depends on SECURITYPERSONKEY being a unique or primary key on TAB_B. It is:
update (select TAB_A.PPYACCOUNT a_PPYACCOUNT, TAB_B.PPYACCOUNT b_PPYACCOUNT
        from TAB_A JOIN TAB_B on TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)
SET A_PPYACCOUNT=B_PPYACCOUNT;
This can set multiple columns. It also currently doesn't work on a view with INSTEAD OF triggers.
Frank's update also works with multiple columns (eg also updating col2 and col2), with this syntax:
