View 6 RepliesIn the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO
AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
SELECT
DNO,
BNO,
c2,
c3,
c4,
c5,
c6,

how to use the MERGE Statement. actually I've used oracle Merge Statement before and it works very well. However today I tried to use and perform a command like that:
Merge into myTable mt using ( select 'data' field1, 'data2' field2, ect from dual
union
select 'data' field1, 'data2' field2, ect from dual
union
[code]...
This has not worked.What am I doing wrong?What could I do to solve this problem and axecute this statement sucessfully?
in Toad I am using this Merge statement , working accordingly.I want to use this merge statement in my form where can I use it.
I created a Procedure in Form Named Proc_merge and call it when validate item of :bankcode
PROCEDURE proc_merge IS
BEGIN
declare
v_com varchar2(5000);
BEGIN
V_COM := '
[code]...
when matched then
update set
trg.v_chq = src.cheque_no, trg.v_bankcode = src.bank_code ,trg.v_debit=src.debit, trg.v_credit=src.credit, trg.v_narration=src.narration
when not matched then
insert (trg.v_type, trg.v_no, trg.v_date, trg.v_chq, trg.v_bankcode, trg.v_debit, trg.v_credit, trg.v_narration)
values (src.voucher_type, src.voucher_no, src.voucher_date, src.cheque_no, src.bank_code, src.debit, src.credit, src.narration)
';
FORMS_DDL(V_COM);
end;
END;
no any result.

I want to write a Merge statement to update the negative values into 1.
I am using Merge statement to copy data from one table to other,
merge into tabA a
using tabB b
on a.id = b.id
when match
update (
)
when not matched
(insert )
This is working all fine, as SQL, but when there is large volume, it blows out as there are intermediate commits for this ?
I have two tables have almost the same columns, how can I use merge statement to update the target table only when there is difference between source and target table. Is there any easier way not compare each column one by one? I am using Oracle 11.2
Here is the MERGE statement:
Merge into tb_trgt trgt using tb_src src
on (src.id = trgt.id)
when not matched then insert (trgt.id, trgt.nm, trgt.addr) values (src.id, src.nm, src.nm)
when matched then update set trgt.nm = src.nm, trgt.addr = src.addr
where trgt.nm <> src.nm or trgt.addr <> src.addr
;
Is there any easier way to specify the where clause in the NOT MATCHED? I don't want compare each column of the tables. Since I may have many columns in the tables.
{code{
i want to apply merge stmt on single table.
CREATE TABLE TEST11(TNO NUMBER(5), TVAL VARCHAR2(100), TID VARCHAR2(10));
INSERT INTO TEST11 VALUES(1,'VIJAYA','TEST');
INSERT INTO TEST11 VALUES(2,'VIJAYA','TEST');
INSERT INTO TEST11 VALUES(3,'VIJAYA','TEST');
INSERT INTO TEST11 VALUES(4,'VIJAYA','');
INSERT INTO TEST11 VALUES(5,'VIJAYA','');

My requiremen is if record is exists then i wan to update some value, if record not existes the i wan to insert new record
I was reading about merge statement and tried some variations,
create table MERGE_TEST(
C1 number,
C2 varchar2(10 char),
c3 number);
insert into MERGE_TEST values(1, 'Name 3', 300);
insert into MERGE_TEST values(1, 'Name 2', 200);
insert into MERGE_TEST values(1, 'Name 1', 100);
commit;

why is result different in this querys?
mbr has 60,000 rows and member has 60,000 rows approx. two tables have indexes on ssn, and citi_no on them.
PK of mbr : mbr_id
PK of member : mbr_id
other columns are not PK, and have no index on it.
I'm wondering why the statment doesn't use index while ssn and citi_no have index.
MERGE INTO mbr t
USING (SELECT mbr_id,citi_no
FROM member) a
ON (t.ssn = a.citi_no)
WHEN MATCHED THEN
UPDATE SET t.asis_mbr_id = a.mbr_id
where t.ssn not in(select ssn from mbr group by ssn having count(*) > 1)
I am getting a (PL/SQL: ORA-00903: invalid table name) compile error in a procedure using a merge statement. I have seen many examples using this technique and am at a loss as to why I can't compile.
the pipelined function is:
FUNCTION f_crcli_pipe(pi_source_data IN sys_refcursor,
pi_limit_size IN PLS_INTEGER DEFAULT pkg_crcli_variables.c_cursor_limit_def)
RETURN CRCLI_AA
PIPELINED

the error is pointing to the TABLE function in the USING clause of the merge statement.
Can I have all the rows in a table updated at once in the merge statement?

UPDATE ....... I want to update all the other rows at once..

I am writing below MERGE statement. In this cardinality between table_a and table_b is 1:2. I.e. each record in table_b corresponds to 2 records in table_a based on columns in ON clause.
Well this query throws below error.

I have a merge statement in one procedure , this job runs on daily . It is running successfully since Jan-19-2010 and giving the below error now.

Intially thers is no records in the TAN_LIST table. When I run the merge statemnt I am able to insert all 15 records into that table.
When I run the same merge statemment second time I am getting the below error.
ORA-30926: unable to get a stable set of rows in the source tables
So that I have used partition by cluase in the slect statement and I am able to resolve the error.
But it's inserting only 14 records not all 15. How to process all 15 records without the error..
I am using the below code to update specific sub-partition data using oracle merge statements.
I am getting the sub-partition name and passing this as a string to the sub-partition clause.
The Merge statement is failing stating that the specified sub-partition does not exist. But the sub-partition do exists for the table.
We are using Oracle 11gr2 database.
Below is the code which I am using to populate the data.
declare
ln_min_batchkey PLS_INTEGER;
ln_max_batchkey PLS_INTEGER;
lv_partition_name VARCHAR2 (32767);
lv_subpartition_name VARCHAR2 (32767);

I want to know how the Oracle optimizer choose joins and apply them while executing the query. So that I will insure about optimizer join before writing any query.
View 2 Replies View RelatedI have a table which has 4 varchar columns( col1, col2,col3, col4). There is data in the table for col1,col2,col3 and col4 is a newly added column. I want to concatenate values from col1,col2 and col3( comma separated) and put it in col4( as col1,col2,col3). Note that col1 or col2 or col3 can have null values and the concatenation should ignore null.
Is it possible to do it in a single SQL statement or should I use a procedure to do this?
I am trying to create a SQL query which will check that various postcode formats are valid, but I am having trouble getting oracle sql to check for values within ranges - for example the following returns no rows, even though most of the postcodes I am dealing with start with 'P'.
select postcode from mytable.addresses
where postcode like '[N-R]%'
;
Am I getting my syntax wrong somewhere?

The conditional statements should not only be executed in sequence, but also if any of them are true they should not be overridden by any subsequent conditional statements being true.

from 'ABCDEFGH' to 'ACEG'
removing 'BDFH' from the source string 'ABCDEFGH'
i giving here the example you can take any valid string i want the result like the above example and also in a dynamic manner means we can give string to a select statement in run time.can it is possible in a select statement only.
