Oracle UPDATE syntax with JOIN and WHERE clause

thank you for the attempt, but I get this error trying your method...
Error report:
SQL Error: ORA-01779: cannot modify a column which maps to a non key-preserved table
01779. 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.
as for the background of what I'm trying to...
I have 2 tables, one that has shipments with no miles (F4941 / Routing Steps), and another that does have miles (F4981 / Freight Audit History).
I want to update the miles & UnitOfMeasure columns for all shipments in the F4941 that currently have 0 miles with the miles found in the F4981 which are connected by Shipment number. Here's my same script, with simpler naming.
UPDATE RoutingSteps
SET RoutingSteps.Miles=FreightAuditHistory.Miles,RoutingSteps.UnitOfMeasure=FreightAuditHistory.UnitOfMeasure
FROM RoutingSteps
INNER JOIN FreightAuditHistory
ON RoutingSteps.ShipmentNumber = FreightAuditHistory.ShipmentNumber
WHERE RoutingSteps.ShipmentNumber = 647143
AND RoutingSteps.Miles = 0
AND RoutingSteps.ShipmentDate > 110365
AND FreightAuditHistory.Category = 'DIS';
hope this helps visualize my intent

Left join and where clause with not equal ( ) returns too many rows
Say I have something like this
Table A
=========
Id
OrderNum
Date
StoreName
AddressKey
Table B
========
Id
StreetNumber
City
State
select a.* from [Table A] a
left join [Table B] b on a.AddressKey = b.Id
where a.StoreName <> 'Burger place'
The trouble is that the above query still returns rows that have StoreName = 'Burger place'
One way Ive handled this is to use a table expression, select everything into that, then select from the CTE and apply the filter there. How could you handle it in the same query however?Hi Joe,
Thanks for your notes.
INT SURROGATE PRIMARY KEY provides a small footprint JOIN ON column. Hence performance gain and simple JOIN programming. In the Addresses table, address_id is 4 bytes as opposed to 15 bytes san. Similarly for the Orders table.
INT SURROGATE PRIMARY KEY is a meaningless number which can be duplicated at will in other tables as FOREIGN KEY. Having a meaningful PRIMARY KEY violates the RDBMS basics about avoiding data duplication. If I make CelebrityName (Frank Sinatra)
a PRIMARY KEY, I have to duplicate "Frank Sinatra" as an FK wherever it needed as opposed to duplicating SURROGATE PRIMARY KEY CelebrityID (79) a meaningless number.
This is how we design in SQL Server world.
QUOTE from Wiki: "
Advantages[edit]
Immutability[edit]
Surrogate keys do not change while the row exists. This has the following advantages:
Applications cannot lose their reference to a row in the database (since the identifier never changes).
The primary or natural key data can always be modified, even with databases that do not support cascading updates across related
foreign keys.
Requirement changes[edit]
Attributes that uniquely identify an entity might change, which might invalidate the suitability of natural keys. Consider the following example:
An employee's network user name is chosen as a natural key. Upon merging with another company, new employees must be inserted. Some of the new network user names create conflicts because their user names were generated independently (when the companies
were separate).
In these cases, generally a new attribute must be added to the natural key (for example, an
original_company column). With a surrogate key, only the table that defines the surrogate key must be changed. With natural keys, all tables (and possibly other, related software) that use the natural key will have to change.
Some problem domains do not clearly identify a suitable natural key. Surrogate key avoids choosing a natural key that might be incorrect.
Performance[edit]
Surrogate keys tend to be a compact data type, such as a four-byte integer. This allows the database to query the single key column faster than it could multiple columns. Furthermore a non-redundant distribution of keys causes the resulting
b-tree index to be completely balanced. Surrogate keys are also less expensive to join (fewer columns to compare) than
compound keys.
Compatibility[edit]
While using several database application development systems, drivers, and
object-relational mapping systems, such as
Ruby on Rails or
Hibernate, it is much easier to use an integer or GUID surrogate keys for every table instead of natural keys in order to support database-system-agnostic operations and object-to-row mapping.
Uniformity[edit]
When every table has a uniform surrogate key, some tasks can be easily automated by writing the code in a table-independent way.
Validation[edit]
It is possible to design key-values that follow a well-known pattern or structure which can be automatically verified. For instance, the keys that are intended to be used in some column of some table might be designed to "look differently from"
those that are intended to be used in another column or table, thereby simplifying the detection of application errors in which the keys have been misplaced. However, this characteristic of the surrogate keys should never be used to drive any of the logic
of the applications themselves, as this would violate the principles of
Database normalization"

CONNECT BY with CROSS JOIN and WHERE not executing as described in doc
Hello all,
please see these two statements. They are the same, but the 1st uses t1 INNER JOIN t2 while the snd uses a CROSS JOIN with WHERE.
The 2nd statement shows one row more than the first, but the CROSS JOIN with WHERE is the same as the INNER JOIN.
The result would be OK if Oracle did:
JOIN -> CONNECT BY PRIOR -> WHERE
But according to the docs it does:
JOIN (and WHEREs for JOINS) -> CONNECT BY PRIOR -> Rest of WHERE
See http://docs.oracle.com/cd/E11882_01/server.112/e26088/queries003.htm#SQLRF52332 for details. There it says:
Oracle processes hierarchical queries as follows:
A join, if present, is evaluated first, whether the join is specified in the FROM clause or with WHERE clause predicates.
The CONNECT BY condition is evaluated.
Any remaining WHERE clause predicates are evaluated.
+.....+
Is this a bug? I'd say yes, because it differs from the docs and it also is not what people are used to ("a,b WHERE" is the same as "a INNER JOIN b").
Thanks,
Blama

Hello Paul,
that means that "a,b" isn't the same as "a CROSS JOIN b".
I don't think that that is really the case.
Do you have docs on this one?No explicit docs just (my) logic - having said that, I suppose it is implied that if you are doing ANSI style joins, it's not the where clauses that
are specifying the join.
If you do t1,t2 where t1.a=t2.a then Oracle figures out the kind of join from the (relevant) where clauses and treats the other where clauses after the CONNECT BY.
If you do t1 cross join t2 where t1.a=t2.a then you are saying the join is completely specified by the CROSS JOIN - i.e it's Cartesian. Oracle doesn't look at the where clauses for this. Therefore
all where clauses are treated as 'other' and are evaluated after the CONNECT BY.
So, in my mind it's 10g that has the bug. -
Absolute dynamic select query with dynamic join and where
Has anyone ever tried creating an absolutely dynamic SELECT query with dynamic Join and Where conditions.
I have a requirement of creating such a query in an Utility Class, and i have written the code. But its throwing my sysntax errors.
Please let me know where am I going wrong OR is it really possible to create such a dynamic Query??
SELECT (FIELDS) INTO TABLE IT_TABLES
FROM ( (ME->TABLE1) inner join ( me->table2 )
on ( on_condition ) )
WHERE (me->where_fields).
Ags.It worked for me in a following way:
select * into corresponding fields of table <result_table>
from (join_string)
where (l_where).
Where the contents of join_string were dynamically build using concatenation. So it will be something like
concatenate ME->TABLE1 'as a INNER JOIN' me->table2 'as b ON (' into join_string separated by space.
<...>
add here matching/reference colums, something like
concatenate 'a~' me->TABLE1_JOIN_COL into temp1.
concatenate 'b~' me->TABLE2_JOIN_COL into temp2.
concatenate join_string temp1 '=' temp2 into join_string separated by space.
<...>
concatenate join_string ')' into join_string separated by space.
And then use similar approach for l_where variable. -
Update statement with joining other tables

If all the values needed to update a given row of table_x are coming from the same row of table_y (or from the same row of a result set of a query involving any number of tables), then you can do something like this:
UPDATE table_x x
SET (col1, col2, col3, ...)
= (
SELECT NVL (y.col1, x.col1)
, NVL (y.col2, x.col2)
, NVL (y.col3, x.col3)
FROM table_y y
WHERE x.pkey = y.expr
AND ...
WHERE ...
;If the WHERE clause depends on the same row of table_y, then it will probably be simpler and more efficient to use MERGE instead of UPDATE.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Cardinality estimator 2014 is off with OR in where clause
Here is my test setup on SQL Server 2014.
-- Create big table
CREATE TABLE [dbo].[Store](
Id int IDENTITY(1,1) NOT NULL,
City int NOT NULL,
Size int NOT NULL,
Name varchar(max) NULL,
CONSTRAINT [PK_Store] PRIMARY KEY CLUSTERED ([Id] ASC)
GO
CREATE NONCLUSTERED INDEX [IX_Store] ON [dbo].[Store] (City ASC, Size ASC)
GO
-- Fill with 100k rows
INSERT Store
SELECT i % 101, i % 11, 'Store ' + CAST(i AS VARCHAR)
FROM
(SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY s1.[object_id]) AS i
FROM sys.all_objects s1, sys.all_objects s2) numbers
GO
-- Create small table
CREATE TABLE #StoreRequest (City int NOT NULL, Size int NOT NULL)
GO
INSERT #StoreRequest values (55, 1)
INSERT #StoreRequest values (66, 2)
Now I execute the following query (I force the index to show statistics estimates)
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR r.City <> 55
Here are the estimates that I get (I'm not allowed to upload pictures):
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 50000
Fixing WHERE clause to use one table not two makes the estimate perfect:
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR s.City <> 55
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 89.74
Switching to 2012 compatibility mode gives estimate of 1 in both cases:
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 1
Could anyone explain the first result? I'm a bit worried about it. The fix in this case is trivial, but this problem gave us quite some headache in more complex real life queries with multiple joins.
Thank you!But not full statistics on a field basis, just sometimes some default stats like total row count that some plans will build. Even your StoreRequest table only has one two-field index that will have a full histogram.
But I've seen SQL Server make massively bad plans on two-field indexes.
I've seen SQL Server go wrong one-column indexes, so that is not a very relevant point.
Temp tables or not, the estimate here is clearly incorrect. SQL Server knows the density of Size and City. It knows the cardinality of the temp table. The density information gives how many rows the the join will produce. The WHERE clause will then remove
a certain number of rows. With no statistics for the temp table, it does not now how many, but it will apply some standard guess.
50000 is a completely bogus number, because the join cannot produce that many rows, and SQL Server is able to compute the join with out the WHERE clause decently. (Well, it estimates 90, when the number is 180.) No, this is obviously a case of the cardinality
estimator giving up completely.
It is worth noting that both these WHERE clauses gives reasonable estimates:
WHERE r.Size <> 11 OR r.City <> 550
WHERE s.Size <> 11 OR s.City <> 550
Whereas these two gives the spooky 50000:
WHERE s.Size <> 11 OR r.City <> 550
WHERE r.Size <> 11 OR s.City <> 550

Using Filter and where clause in GoldenGate
Hi,
I need to use where clause in extract process.
The condition i need to use is :- where (CODE LIKE '10%' OR CODE LIKE '0%')
how to use LIKE operation along with OR in extract.
I have multiple where conditions these are straight i.e = and <> which are working fine. But LIKE is not working.
Please do assist for the same.
Thanks.GoldenGate uses FILTER and SQLPREDICATE (and COMPUTE is a variation that can work, depending on how you are trying to manipulate the data).
To filter data, you can use:
● A FILTER or WHERE clause in a TABLE statement (Extract) or in a MAP statement (Replicat).
● A SQL query or procedure
● User exits
FILTER comparison operators include:
Comparison operators:
> (greater than)
>= (greater than or equal)
< (less than)
<= (less than or equal)
= (equal)
<> (not equal)
WHERE clause permissible operators:
Column names PRODUCT_AMT
Numeric values -123, 5500.123
Literal strings "AUTO", "Ca"
Built-in column tests @NULL, @PRESENT, @ABSENT (column is null, present or absent in the row). These tests are built into Oracle GoldenGate. See “Considerations for selecting rows with FILTER and WHERE” on page 155.
Comparison operators =, <>, >, <, >=, <=
Conjunctive operators AND, OR
Grouping parentheses Use open and close parentheses ( ) for logical grouping of multiple elements.
You could try using a GoldenGate string function. You know what the leading one or two characters (0 and 10) are.
Use the @STREXT function to extract a portion of a string and do a comparison there. Or take care of it using SQLEXEC on replicat (call a function to be able to use LIKE). -

Qualifying Expression and WHERE CLAUSE Extension
I would like to know the exact difference between 'Qualifying Expression and WHERE CLAUSE Extension'. Since both are meant to contain some CONDITION that would facilitate the Edit Check's success, So I am sometimes a bit confused with these too as to when to use what.
Can someone help Please??As you can tell from my previous posts (requests!) - I'm a newbie to OC.
From the documentation - it appears that both Qualifying expression and Where Clause work the same way but the way they execute is different.
Qualifying expression is applied after the fetch (key fields and question response data from DCM cursor i.e., after the cursor fetches the data) and Where clause filters before QG fetch.

I have the follow code snippet which is intented to go to a form on a successfull save. I query some data based on the save then build a url to navigate to a new form. I want the form to show only data that is lacking in one column not being populated (column is null). The url works, but the form detail where clause is ignored. Does anyone have any experience with passing detail where clauses to a form? Did I miss something in the code below?
begin
select count(rl_id) into n_rl_id_cnt
from rfq_lines
where part_part_id is null and rh_rh_id=n_rh_id;
exception
when others then
null;
end;
htp.p('cnt '||to_char(n_rl_id_cnt));
if n_rl_id_cnt>0 then
htp.p('cnt >1');
my_url := 'PORTAL30.wwa_app_module.link?' ||
'p_arg_names=_moduleid&p_arg_values=3677858481' ||
'&p_arg_names=_show_header&p_arg_values=YES' ||
'&p_arg_names=rh_id&p_arg_values=' || LTRIM(TO_CHAR(n_rh_id)) ||
'&p_arg_names=_rh_id_cond&p_arg_values=%3D'||
'&p_arg_names=_detail_where_clause&p_arg_values=part_part_id%20is%20null'; -- <this is not working right. where clause is ignored.
htp.p(my_url);
go (my_url);Hi Jeffrey ,
You need to use a custom Format script for the field.

Define a Standalone Download Integrator with an Additional Where clause - SQL error
Hi,
I am trying to create a standalone integrator with an Additional Where clause. Followed the steps mentioned in the metalink note 360105.1. When I run the integrator, I get the following error message.
Please resolve the following error to continue.
SQL error: ORA-00936: missing expression occurred
processing stored SQL for Content 20007:GENERAL_441_CNT.
When I look at the log file, here is what I can see:
10/22/14 10:50 AM AJPRequestHandler-HTTPThreadGroup-15 TRACE BneHrSQLControl - SQL:SELECT FROM PER_PEOPLE_V where last_name=$PARAM$.last_name
10/22/14 10:50 AM AJPRequestHandler-HTTPThreadGroup-15 TRACE validateSQLStatement value of sqlStatement is: SELECT FROM PER_PEOPLE_V where last_name=:RSQLP1
10/22/14 10:50 AM AJPRequestHandler-HTTPThreadGroup-15 DETAIL BneHrSQLControl.validateSQLStatement() paramName: last_name
10/22/14 10:50 AM AJPRequestHandler-HTTPThreadGroup-15 DETAIL BneHrSQLControl.validateSQLStatement() error in SQL: java.sql.SQLSyntaxErrorException: ORA-00936: missing expression
So, clearly, the SQL statement that is getting built internally is wrong. Ideally, I would expect the statement to be something like this:
SELECT * FROM PER_PEOPLE_V where last_name=$PARAM$.last_name.
RDBMS : 11.2.0.3.0
Oracle Applications : 12.1.3
Any pointers towards the resolution of the issue would be of great help.
Thanks in Advance!

Hi! Everyone, I have some problems with JOIN and Sub-query; Could you help me, Please?
Dear Sir/Madam
I'm a student who is interested in Oracle Database and
I have some problems with JOIN and Sub-query.
I hope so many of you could help me.
if i use JOIN without sub-query, may it be faster or not?
SELECT field1, field2 FROM tableA INNER JOIN tableB
if i use JOIN with sub-query, may it be faster or not?
SELECT field1,field2,field3 FROM tableA INNER JOIN (SELECT field1,field2 FROM tableB)
Thanks in advance!Hi,

As the others have said, the execution plan will give you a better idea about which is faster.
If you're trying to see how using (or not using) a sub-query affects performance, make the rest of the queries as similar as possible. For example, include field3 in both queries, or ignore field3 in both queries.
In this particular case, I guess the optimizer would do the same thing either way, but that's just a guess. I can't see your execution plans.
In general, simpler code is faster, and better in other ways, too. In this case
tableB
is simpler than
(SELECT field1, field2 FROM tableB)
Why do you want a sub-query in this example? -
Difference of 'Specify Fragmentation Content' and 'where clause Filter ' ?
What is the difference of ‘Specify Fragmentation Content’ and ‘where clause Filter ‘
As per my understanding Both looks like limit the data ?'Specify Fragmentation Content’ is for Union-ing tables, e.g. one table has data for 2008 while other has 2005-2007, so 'Specify Fragmentation Content’ tells server where to go look for data.
'Where clause Filter' is for limiting data from the table, e.g. where status = 'Funded'
