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.

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;
[code]...
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
PARALLEL_ENABLE(PARTITION pi_source_data BY ANY)

the error is pointing to the TABLE function in the USING clause of the merge statement.

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.
----Error---
ORA-12801: error signaled in parallel query server P011
ORA-30926: unable to get a stable set of rows in the source tables
However, the same statement executes successfully when PARALLEL hint is removed altogether. (There are no duplicates in table_b based on unit,group,loc columns.)
-----Query--------
MERGE /*+ PARALLEL(8) */
INTO table_a a
USING table_b b
ON (a.unit = b.unit AND a.group = b.group AND a.loc = b.loc)

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);

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432
23 asdc 1 Audit 1996 June 17 1200
65 affc 2 Location USA TX AUS Hilton 92305
65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime
23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200

I am trying to find the best solution for the following problem
I have a table called HIERARCHY with 3 columns.
col1 col2 col3
------------------------
1
1 2
1 2 3
4 5
6 7 8
I would like to check if the table contains invalid records. Col1 , Col2 and Col3 are seen as hierarchy levels and col1 is the top level.
For instance record 1,2,3 (level3) is valid because it exists record 1,2 (level 2). Moreover 1,2 record (level 2) is valid because it exists record 1 (top level).
However 4,5 and 6,7,8 are not valid as higher levels are not completed.
How can I check in a single SELECT statement if the table contains invalid records? Maybe analitical functions or regular expressions?!

1) SQL Statements are not using IMPLICIT CURSORS.
2) Only the SQL statements of the PLSQL program create implicit cursors.

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.
