Writing CMP Finder SQL Syntax?

What is the syntax for writing the finder SQL for CMP? From the CMP sample code for the OAS it looks like it might be &fieldname <op> $1 (for the first parameter?)?
Joe McDaniel

You can create custom CMP Finder Methods which takes appropriate sql but not SQLJ and JDBC.
i.e if you are adding a custom finder method in orion-ejb-jar.xml it takes only SQL not java code
In JDeveloper select orion-ejb-jar.xml in the project and right-click on it and choose Settings option
Select the Entity bean in the navigator and choose Finder methods
Click on Add. The dialog box will allow to add a new finder method with SQL query
Click on Help for specific information
Couple of hints are
Partial
Whether or not the specified query is a partial one. A partial query is the 'where' clause or the 'order' (if it starts with order) clause of the SQL query.
Queries are partial by default. If partial="false" is specified then the full query is to be entered as value for the query attribute and you need to make sure that the query produces a result-set containing all of the CMP fields. This is useful when doing advances queries involving table joins and similar.
Query
The query part of an SQL statement. This is the section following the WHERE keyword in the statement. Special tokens are $number which denotes an method argument number and $name which denotes a cmp-field name. For instance the query for "findByAge(int age)" would be (assuming the cmp-field is named 'age'): "$1 = $age".
Return type can be collection if the query is returning more than one row of data or it could be the entity bean type itself (if it is only one row)

ANSI SQL Syntax - What belongs to join-clause and what to where-clause

Hello,
we currently have a discussion about the ANSI SQL Syntax where we do not agree what belongs to the join clause and what belongs to the where clause in an ANSI Sytnax SQL Query.
Lets say there is a query like this:
+SELECT *+
FROM employees emp, departments dept
WHERE emp.dept_country = dept.dept_country
AND emp.dept_name = dept.dept_name
AND dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Primary key of the departments table is on the columns dept_country, dept_name and dept_type. We have a Oracle database 10g.
Now I have rewritten the query to Ansi Syntax:
+SELECT *+
FROM employees emp
JOIN departments dept
ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name
WHERE dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Another developer says that this is not completely correct, every filter on a column that belongs to the primary-key of the joined table has to be in the join clause, like this:
+SELECT *+
FROM employees emp
JOIN departments dept
+ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name AND dept.dept_type = 'HQ'
WHERE emp.emp_lastname = 'Smith'
Can somebody tell me which on is correct?
Is there any definition for that? I couldn't find it in the Oracle Database definition.
I just found out the names of the ANSI documents here: http://docs.oracle.com/cd/B19306_01/server.102/b14200/ap_standard_sql001.htm#i11939
I had a look at the ANSI webstore but there you have to buy the PDF files. In my case thats exaggerated because both of the Queries work and i am just interessted if there is one correct way.
Thank you in advance
Marco

Hi,
As i guideline i would say, answer the question: should the result of the join be filtered or should only filtered rows be joined from a particular table?
This is helpful in the case of outer joins also, for inner joins it doesnt matters as said already be former posters, where there may be hughe semantical differences depending of where the predicates are placed.
From performance view, if we talk about oracle, take a look a the execution plans. You will see that there is (probably) no difference in case of inner joins. Even in case of outer joins the optimizer pushes the predicate as a filter towards the table if it semantically possible.

Converting XPATH to SQL syntax?

HI, all
I am looking for a third party tool to convert XPATH syntax to SQL syntax?

CMP Finder Method

Could you supply a couple of examples of setting up a custom CMP Finder Method using both SQLJ and JDBC?
In particular how is the SQL coded in the "SQL Query" textbox on the "Method" tab? How are the parameters and the result set referenced and returned? What is the return type?
Simple Select / Where clause multirow and single row examples should suffice.
I using JDeveloper 9.0.2.8.2.
Thanks.

SQL Developer 1.1.0.21: Issues with Data Grid and SQL syntax checking

In this new release of SQL Dev, when I execute a SQL in the SQL Worksheet and click in the Data Grid in the Results tab and try to navigate within a record using arrow keys, the grid cell enters into edit mode by default and so I cannot use the Left or Right arrow keys to navigate the grid. I am forced to use tab key to navigate. This is counter intuitive in my opinion.
Is there any option to change this behavior?
Another issue that I have come across is with SQL syntax checking. In some cases, when I press F9 to execute a SQL, it shows the SQL as executed i.e. shows something like 0.0134 seconds in the toolbar and no results displayed. In reality, the SQL had some syntax error which were NOT reported. This can be frustrating since now I have to fall back to SQL*Plus or TOAD just for syntax check.
I like the fact that SQLDev highlights the current SQL but it would be more useful if it just indicated the first line of the current sql instead of highlighting the whole sql.

I am forced to use tab key to navigate. This is counter intuitive in my opinion."
In the "Results" tab, Click Ctrl & Tab keys (at the same time) or with mouse click on any cell other than the first column (a sequence or rownum), you will be able to navigate using the arrow keys.

The 0.0134 seconds could be the result of the most recently executed successful statement. Check the Script Output tab for errors. Use F5 (Run Script option) instead of F9.
"I like the fact that SQLDev highlights the current SQL but it would be more useful if it just indicated the first line of the current sql instead of highlighting the whole sql."
On the SQL statement (or code), Right Click -> Format SQL (or press Ctrl & B), proper formatting would help.
I use version 1.0.0.15.57 and seems to be working allright.

Writing extension for SQL Developer

Hello all,
I'm new to writing extensions for SQL Developer using JDeveloper. Can you help me with some example with common functionality, like how to get the current connection? Is there some documentation for the oracle.sqldeveloper package? The example may include some techniques like how to get the schema name for a chosen table, get some other info for the table and so on.
Thank you in advance!

Sql syntax in jsp

Hey All!
Im trying ot use a a bean to select data from a table where email != ''
The funny thing is my code works in one couple of jsp/bean but not in another, even though it's the exact same code.
This works
The Bean:
String sql = "SELECT applicantid, firstname, lastname, dob, " +
"homestreet, homestate, homecity, homezip, " +
"email, college, major, standing, " +
"graddate, schstreet, schcity, schstate, " +
"schzip, schphone, resOne, resTwo, " +
"resThree, waiver, bioletter, password, " +
"homephone " +
"FROM apptest " +
"WHERE " + filter + " " +
"ORDER BY " + orderBy;
The filter is the String "email != ''" and orderBy ="lastname"
Works perfectly!
But when I use similar code for another table
Code:
String sql = "SELECT providerid, applicantid, pin, title, " +
"company, firstname, lastname, phone, " +
"email, recletter " +
"FROM provtest " +
"WHERE " + filter + " " +
"ORDER BY " + orderBy;
with filter as "email != '' " and orderBy = "lastname"
I get the following error:
Error in findRecords ProviderUtility(Syntax error or access violation, message from server: "You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1")
Keep in mind that email != '' (these are single quotes)
I am really baffled.
Ike

"The funny thing is my code works in one couple of jsp/bean but not in another, even though it's the exact same code."
If it's EXACTLY the same code, what did you need another bean for?
If you needed a new bean, then it's not exactly the same.
Why aren't you using PreparedStatement to escape strings and dates for you?
Believe the engine when it tells you there's a mistake.

How to find sql statement which generates LOCK

Hello,
In my plsql procedure i have used SELECT FOR UPDATE NO WAIT statement to avoid the current record used by another user.
Actually i want to find which sqlquery is locking the Object other than my procedure.
I can find the session id which is locking the object but i can not able to find sql text.
How to find the SQL text from particular LOCKING Session id as v$sql or v$sqltext or v$sqlarea dont have session id?
Any help can be appreciated.
Thanks in advance.

It's not necessarily that easy to find the statement that was responsible for the lock.
It depends.
First of all, it depends on version.
If you're >= 10g and you're lucky and you're licensed for Diagnostic Pack, you might find it in ASH.
If the statement that's responsible for the lock is also waiting on something else or runs for long enough, then ASH will almost certainly have it.
Doug Burns has a 10-part series on the subject.

SQL Syntax Issue

This is a weird one!!!
I am using Dreamweaver/php/mysql and I am in the process of
developing the forms that edit articles that have been added to the
CMS. I have a page called edit.php which has the current list of
articles. Each article has a radio button next to it and have given
it an id of "id" (which is what I called it in the DB). On
selecting this article, and hitting submit, this should load up a
editnews2.php. On editnews2.php I have a filtered recordset that
filters on "id " so that it loads the article selected into the
editnews2 form. I have bound the fields in the form to the related
fields in the recordset.
When I test this out using the TEST button, in the recordset
pop-up window and enter an id, it retrieves the correct article
from the database. However, when I do it using the forms, I get an
error:
"You have an error in your SQL syntax; check the manual that
corresponds to your Mysql server version for the right syntax to
use near " at line 1"
This is really weird because the recordset works and
retreives the data no problems, which mean the connection file path
is correct and other parameters are correct. I have tried lots of
times to try and figure this out but I am now really stuck.
Could anyone shed some light on this one?
regards

What that means is that the way Dreamweaver is building your
query
contains a mistake - probably an extra quotation mark or
something like
that.
Go into Code view and use echo to display the actual SQL
query being
sent to the database. That will give you a clue as to where
to start
troubleshooting the rest of the code.

Error in SQL syntax

Hi all,
I have an SQL database which up untli about 20 minutes ago was fine. I have a complex contact form whic is (was) all finished. I have added a couple more tables to the database (now totalling 4), in order to create a registration / login page.
(Is it okay to have 4 tables in 1 database?)
Anyway. I have just finished with the login stuff and all works fine. I decided to have a quick look around the site and make sure everything is okay - but for some reason when I navigate to the "complex contact form" - I get this message:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASCE LIMIT 0, 150' at line 1
The registration wizard and login pages still work, and in general the site is browseable. But this page will not work and I have no idea why?
Does anyone have any suggestion? All I have done since it worked is add 2 other tables as I said....
Thank you / please help!

There was a typo in my previous post. There should be only one $ in $query_recordsetName. I should also have added that "recordsetName" is the name of your recordset. I would have thought it was obvious, but I see you're limiting the number of results, so the name is slightly different.
The other thing is that you have not put it where I told you. Apart from that...
$query_rscontacts1 = "SELECT contacts.Logo, contacts.Industries,
contacts.coverage, contacts.misc, contacts.id, contacts.email,
contacts.website FROM contacts WHERE {$NXTFilter_rscontacts1} ORDER BY
{$NXTSort_rscontacts1}";
$query_limit_rscontacts1 = sprintf("%s LIMIT %d, %d", $query_rscontacts1, $startRow_rscontacts1, $maxRows_rscontacts1);
echo $query_limit_rscontacts1 . '<br />';
$rscontacts1 = mysql_query($query_limit_rscontacts1, $Contacts) or die(mysql_error());

How to find sql server backup was taken under compression mode

Hello,
How to find SQL server backup was taken under compression mode ? I have disabled the Compress Mode backup setting but I want to make sure the backup is taken without compression.
Is there a script for that?

That is only a default setting, in backup command you can always overwrite it to a different value.

This looks to be an error with the web site you are visiting, not a problem with your PC. I suggest you contact the web site owner. The error suggests a problem with programming against a MySQL database, which is not a Microsoft technology.

I have been trying to figure out how to find sql or user who are pharse sql but not executing them. thats becoz my execute to prase % in my AWR report is negative. meaning someone is parsing statements and NEVER executing them. They are just chewing up your CPU, latching the shared pool, killing your performance.
which is not a good thing and i want to find out what user is doing that or what SID or what sql is diong whats its doing. How can i find that out. Any querys out there to do that or ?? THANKS

SQL syntax error...

SQL Syntax:
select ename||'-'||job from emp
Initially, I was using the .Net Framework Data Provider for Oracle and had no problem bringing up the Query Builder in VS 2008. However, when I use the ODP .Net from Oracle, I get an error when bringing up the Query Builder:
Error in SELECT clause: expression near '|'.
Unable to parse query text.
It seems like when uing ODP .Net, it does not like the concatenation in the Select statment.
Any clue why?

Is this consistently reproducible for you? Is it query builder specific? What version of ODP are you using? I just tried this with 11.1.6.20 ODP and it worked fine..
Cheers
