SQL to SQL Append

Hi,
I have a interface to load data from tables to table into same Oracle server, the target table is truncate every time that run interface and the data is just insert (don't update), i read that can use "IKM SQL to SQL Append" to avoid extra loading phases ( like flow tables, create index, etc. ). I put source table and datastore table from the same model, select "Staging Area Diferent from Target" and select the apropiate staging. The problem is that i can select the "IKM SQL to SQL Append" in the flow tab.
Please can you help me with that ? i need this option to improve performance and space, every time that this interfaces run load aprox. 3 million of registers about 9 times with diferent conditions.
Thanks.

Hola Juan, que tal estas?
Eso es muy sencillo....
Just import (or use if it is already imported) the KM Control Append and change the option "Flow Control" to No.
Plus, let the Staging Area together at Target.
I believe that will solve your problem because will generate just one step to load the data...
If you have big problems on this, is very simple to change a KM....
Un Saludo!

Slow Inserts Using IKM SQL to SQL Append

Hi all.
I'm in a big, big trouble.
I have a interface that gets that from the source and insert in the target (obvious)... but the unique way to insert into target is using SQL to SQL Append.
Unfortunately, the inserts are about 10 rows/sec. Very, very, very slow.
There are any ways to do the Agent faster than this?
Regards.

My Staging Area is different from the target area, but unfortunately I'm not able to change this 'cause my sources are accessed via DBLink and there are restrictions to it, enabling only the IP and HostName of my ODI database. My target tables are located in a third server, in the same domain as my ODI database, but there are no DBLinks between them so I have to use SQL to SQL Append.
Thanks in advance.

ODI - IKM SQL to File Append - Header not Generated

I'm using ODI IKM SQL to File Append to create a text file, but the header is not being generated. And the GENERATE_HEADER is set to Yes. The file is Tab delimited and the Heading (number of lines) is set to 1.
Seems to only be an issue with HFM files coming from the Unix server.
Any suggestions?
Thanks, Mike

The last two columns in the file are numeric which seems to be causing the issue. Will change formatting for the two columns (String, Numeric, etc.) to see if I can resolve the header issue.

I understand you were trying to post something helpful to people, but sorry, this list is appalling.
1) Use Bulk Processing feature BULK COLLECT with LIMIT and FOR ALL for DML instead of row by row processing
No, use pure SQL.
2) Use Data Caching Technique/Options to cache static data
No, use pure SQL, and the database and operating system will handle caching.
3) Use Pipe Line Table Functions whenever possible
No, use pure SQL
4) Use Global Temporary Table, Materialized view to process complex records
No, use pure SQL
5) Try avoiding multiple network trips for every row between two database using dblink, Use Global temporary table or set operator to reduce network trip
No, use pure SQL
6) Use EXTERNAL Table to build interface rather then creating custom table and program to Load and validate the data
Makes no sense.
7) Understand Oracle's Cost based Optimizer and Tune most expensive SQL queries with help of Explain plan
What about using the execution trace?
8) Follow Oracle PL/SQL Best Practices
Which are?
9) Review tables and their indexes being used in the SQL queries and avoid unnecessary Table scanning
You mean design your database and queries properly? And table scanning is not always bad.
10) Avoid costly Full Table Scan on Big Transaction tables with Huge data volume,
It depends if that is necessary or not.
11) Use appropriate filtration condition on index columns of seeded Oracle tables directly mapped to program parameters
No, consider that too many indexes can have an impact on overall performance and can prevent the CBO from picking the best plan. There's far more to creating indexes than just picking every column that people are likely to search on; you have to consider the cardinality and selectivity of data, as well as the volumes of data being searched and the most common search requirements.
12) Review Join condition on existing query explain plan
Well, if you don't have your join conditions right then your query won't work, so that's obvious.
13) Use Oracle hint to guide Oracle Cost based optimizer to choose best plan for your custom queries
No. Oracle recommends you do not use hints for query optimization (it says so in the documentation). Only certain hints such as APPEND etc. which are more related to certain operations such as inserting data etc. are acceptable in general. Oracle recommends you use the query optimization tools to help optimize your queries rather than use hints.
14) Avoid applying SQL functions on index columns
Why? If there's a need for a function based index, then it should be used.
15) Use appropriate hint to guide Oracle CBO to choose best plan to reduce response time
See 13.
In short, there are no silver bullets for dealing with performance. Each situation is different and needs to be evaluated on its own merits.

PL/SQL vs SQL

What are the fundamental differences between PL/SQL and SQL?

Just to expand on what was said.
PL/SQL is a formal procedural language based on Ada (Ada and Pascal are very similar). PL/SQL is in that respect equivalent to C, Pascal, Visual Basic etc.
What makes PL/SQL different (a 4GL instead of a 3GL) is that it is specifically designed to deal with data processing problems in Oracle using SQL.
In 3GLs you need to use SQL pre-compilers or special classes (wrapping the database's SQL call interface) to talk SQL to the database. E.g. Pro*C precompiler for use with C. The TQuery class in Delphi that wraps the Oracle Call Interface (OCI) into an object class.
PL/SQL goes further as it allows you to natively use SQL inside the language, as if it is part of the language. The PL compiler/PL engine is however clever enough to recognise SQL statements and do the complex stuff needed to make a SQL call to the SQL engine. It handles bind variables for you. It handles SQL data types for you. It does the SQL engine call for you. It fetches the data from the SQL engine for you. Etc.
Using SQL natively in the PL language is what makes PL/SQL so powerfull. It blurs the line between having to deal with two separate langauges - a procedure (and object orientated) programming language and the SQL language.
This blurring does have its cons . Developers often fail to recognise just what is PL and what is SQL ito doing a proper program design and implementation. Or they treat PL/SQL as something different than Java, Delphi or C/C++. A programming language is a programming language, Programming 101 fundamentals apply. Irrespective of the language. Period.
For example, they use PL/SQL cursor fetch loops to process SQL data in a row-by-row fashion, instead of using SQL to do that work instead. SQL is by far superior in this regard. Or they use SQL (i.e. SELECT func() INTO var FROM dual) to assign values from functions to PL/SQL variables. Why use SQL to do perform this variable assignment when dealing with PL variables?
There are numerous brain farts from developers in this respect. Not understanding PL/SQL. Not even bothering to familiarise themselves with the Oracle manuals on the language. Which is a pity as this result in crappy code and a developer that fails to understand Oracle. Worse, developers start to dislike Oracle because it "does not work properly" due to their utter failure to grasp the concepts of the database and the language.
However, if you understand what PL is and what SQL is in PL/SQL, and you treat both languages correctly, no other language on this planet allows you to process Oracle data more effectively. Fact: PL/SQL scales and performs better than whatever Java architecture and code you can deploy on an application tier.

XML parsing with SQL/PL-SQL

Hi,
My question is about how can an XML message can be best parsed using SQL/PL-SQL.
The scenario is as follow. The XML message is stored in a CLOB; only some of its data needs to be extracted; there are six different types of structures of XML; the size of each XML is about 50 lines (maximum depth level is 3); the data could be written in English or Greek or French or German or Russian; this is going to be done every hour and the parsing is going to be against 3,000 records approx.
In the development, I need to take into consideration performance. We are using Oracle 10, but we could migrate to Oracle 11 if necessary.
Apologies for this basic question but I have never done XML parsing in SQL/PL-SQL before.
Thank you.
PS I have copied this question to the XML forum.

SQL>The variable xml in the sample code is the XML DOM object. XML functions can be used against it (e.g. to extract values in a tabular row and column structure).

ORA-06512: at line 5This XML contains 2 fragments. A row structure and a data structure. It is not a valid XML and as such cannot be parsed. If a root tag is used to encapsulate these 2 fragments, then it will be a valid XML structure.
In the development, I need to take into consideration performance. We are using Oracle 10, but we could migrate to Oracle 11 if necessary.Have not run into any XML performance problems specifically - and am using it extensively. Even large XMLs (10's of 1000's of elements) parse pretty fast.

Dilemma of an OCA (SQL, PL/SQL) with 4 years work-ex

Dear all,
I am an OCA(SQL, PL/SQL) and working on a enhancement/production support project (Tech: JAVA and Oracle, Func: Insurance) in my firm. I am doing quite well here and keep updating myself using oracle documentation and application functionality. But in a long term, I am confused about my career path, what should I do next? Should I upgrade myself with certification in advanced PL/SQL or should I move towards DBA activities or should I learn JAVA to be an software architect?
Personally, I have great interest in oracle database, design and implementation, what can be a career path for a software architect?
Please help.

Please help.Bringing you PL/SQL up to OCP by studying for and taking 1z0-146 is probably a straightford and low impact descision.
It may not however be in the route you wish to take your career, but it is relatively low cost and good gain.
My impression is your not currently into Java ... learning that from the bottom may be a hard process and even having learn Java than in itself does not make one a software architect.
Take a browse down all Oracle Certifications at [http://www.oracle.com/education/certification] ... certifications ... view all certifications ... but remember not all Oracle products / technologies have associated certifications.
Consider SOA or BIEE or Oracle Application Express as well

Convert Oracle SQL line to SQL Server SQL

Hi All,
I'm trying to convert this Oracle SQL to SQL that will work with SQL Server 2008 and am having some trouble with the MOD function. Anyone have any SQL Server chops?
Oracle SQL
TBL_MAIN.AuthoredDate- MOD (TBL_MAIN.AuthoredDate - to_date ('2012-01-01', 'fxYYYY-MM-DD'), 7) + 6 AS "Week Ending"
SQL Server Code
TBL_MAIN.AuthoredDate - ((Cast(TBL_MAIN.AuthoredDate as DATE) % CAST('2012-01-01' AS DATE)), 7) + 6 AS "Week Ending" Thanks,
John
Edited by: Johnbr (Oracle10G) on Mar 1, 2013 8:41 AM

ahhh.. I just had to change my thinking... I got it now:
SQL Server SQL
DATEADD(dd, 7-(DATEPART(dw, TBL_MAIN.AuthoredDate)), TBL_MAIN.AuthoredDate) AS 'Week Ending'

You can assume that for the first timestamp entry, all SID are new.
eg:1.25.02timestamp new sid(10,20,30)
compare that sid with next timestamp of sid
eg:1.25.02timestamp has sid 10 and 1.30.02timestamp has sid 10 so existing sid is 10
1.30.2timestamp don't have 20,30 compare with 1.25.02 timestamp so sid 20,30 are deleted
1.30.2timestamp have 40 so newsid is 40
then compare the secondtimestamp(1.30.2timestamp ) to thirdtimestamp(1:35:00)

Cancel runnning SQL in SQL*Plus Worksheet?

Hi,
can I Cancel a runnning SQL in SQL*Plus Worksheet?
Thanks
Markus

Probably not in current versions.
SQL*Plus Worksheet is just a Java wrapper around
command-line SQL*Plus. I recall the EM team were keen
to see a cancelling feature in 10g, which is one of the
reasons EM 10g will call iSQL*Plus.
The iSQL*Plus web interface has had cancel for a few versions
already. It has a button specially for that.
(For reference, the EM forum is at Enterprise Manager

Suggest a book for oracle 8i :sql,pl/sql

hello friends,
i am new to this forum..
i am planning to write oracle certification (OCA) iz001 exam.
for that i need to prepare oracle 8i sql,pl/sql..
so please any1 of u suggest a book and the author name..
thank u..

I'd really recommend you study an actual supported version.

SQL, PL/SQL Expression and PL/SQL function

In a Post Calculation Computation field I wanted the following computation:
if B is X
then
field = A
else
field = B
end if;
or as a decode
Decode(B,X,A,B)
I could not get this to work so I wrote a database function that simulates the decode. So when I put:
My_decode(B,X,A,B)
in the field it did work.
Basically I am not sure what kind of code one is expected to put into SQL, PL/SQL Expression and PL/SQL function fields. Can someone give an example of each? Also the APEX help is sometimes incorrect.
For example if you click the "Post Calculation Computation" label it says:
The For example, if this item is named P1_X, you could use post calculation expressions such as UPPER(:P1_X), INITCAP(:P2_Y), MIN(:P1_X,:P2_Y-200), NVL(:P1_X,:P2_Y), or a function call such as return my_func(:P1_X); to set the final value of the item.
But if you put return my_func(:P1_X); in the field you get an error. It should be just my_func(:P1_X);
thanks Rene

DECODE is only available in SQL, so would have to be used in a SQL Expression.Yes, that's what APEX keeps telling me when I use in in a field that has "SQL or PL/SQL expression" above it. So what do you put in the field?

Using the equivalent of a BREAK ON command in SQL Developer SQL window

Folks.
In SQL*PLUS "BREAK ON Col1 ON Col2;", I can generate a report similar to the following:
Col1Value1 Col2Value1 Col3Value1
Col3Value2
Col3Value3
Col2Value2 Col3Value1
Col3Value2
Col3Value3
Col1Value2 Col2Value1 Col3Value1
Col3Value2
Col3Value3
Col2Value2 Col3Value1
Col3Value2
Col3Value3
etc.
I want to be able to do the same thing in my SQL Developer SQL window so that I can export the results to a spreadsheet file.
Does anyone know if this is possible?
I've tried using the SQL*PLUS BREAK command in my SQL Developer window but it appears to be ignored. My resultset looks something like
Col1Value1 Col2Value1 Col3Value1
Col1Value1 Col2Value1 Col3Value2
Col1Value1 Col2Value1 Col3Value3
Col1Value1 Col2Value2 Col3Value1
Col1Value1 Col2Value2 Col3Value2
Col1Value1 Col2Value2 Col3Value3
Col1Value2 Col2Value1 Col3Value1
Col1Value2 Col2Value1 Col3Value2
Col1Value2 Col2Value1 Col3Value3
Col1Value2 Col2Value2 Col3Value1
Col1Value2 Col2Value2 Col3Value2
Col1Value2 Col2Value2 Col3Value3
.

OK thanks.
I did get around this by using SQL*PLUS to generate an output file with a separation character between the columns and spooling the SQL*PLUS output to a text file.
I then open the text file with Excel and specify the same character as a column separator. Seems to load properly into Excel.
