SV: Calling procedures from 2 different databases
Hi there! One database per SqlmapConfig - that's the rule. But if your databases and the data is tightly coupled and if you don't need a different sqlMapConfig setting setup (don't need ping query, lazyLoadingEnabled setting etc) Wouldn't it be more clean to have one sqlMapConfig file ? Works super for me in a Spring app with connection to a Sybase and MS-SQL database, then the connectionUrl, username, password is located in a separated java.properties file. It's small web app with quartz jobs, but it's the most stable application I have every made and easy going :-) In general, you should keep the SQL for the different databases in different XML files - although this is not strictly required. I still have have one sql.xml file for each domain model bean, so if your domain model bean contains data from both databases, I don't see it's good thing to split it in two different xml's from my point of view. Why split it ? Where the data is located, doesn't matter, your domain model bean does :-) Anyway, feel this makes it more easy and less files to handle, from my point of view. So, a particular instance of a DAO is tied to one and only one database. Yes one DAO to one database . Good luck Vinaya still :-) Erlend -- Fra: Jeff Butler [mailto:[EMAIL PROTECTED] Sendt: 24. oktober 2007 21:51 Til: user-java@ibatis.apache.org Emne: Re: Calling procedures from 2 different databases One database per SqlmapConfig - that's the rule.

SV: Connecting to 2 different Databases
Hi there!
Your real problem working with 2 different databases, is that they are of
different versions and as long the driver class is the same in 8i and 9i, your
are stuck to one driver :-)
As far as I know how.
What you could try, is to use a 8i driver to see if the query runs agains the
8i database, if it runs, then the fun starts :-) Then you need to find a driver
that runs both for your 8i and 9i databases and your query :-) 9.0.2 is not the
one :-)
You could try to change from java.sql.Timestamp to java.sql.Datetime if it's
the timestamp is the problem ?
No you shouldn't have two config files, you could, but the problem is the same
name on the driver class for 8i and 9i.
A good sql tool, is DbVisualizer, recommend the Personal one, then you can set
up different db connetion to the same database with different jdbc driver, that
can maybe help you to figure this out.
Good luck !

Emne: Connecting to 2 different Databases
Hi,
I am using iBatis with Spring.
I need to connect to 2 databases of different versions.
I have both the data sources declared in applicationContext.xml
ERP is on Oracle 8i and dataware is on 9i
bean id=ERP class=org.apache.commons.dbcp.BasicDataSource
property name=driverClassName
valueoracle.jdbc.driver.OracleDriver/value
/property
property name=url

/bean
bean id=dataware

value
jdbc:oracle:thin:@ddd.xyz.com::DWD
/value
/property
property name=username
valueuser/value
/property
property name=password
valuepassword/value
/property
/bean
I am using jdbc_9.0.2.jar.
I am getting the following error while executing the query for a table in 8i
database..
Executing Statement: select PO_NBR, SCHEDULE_DATE, PROMISE_DATE,
ORDER_QTY, SHIPPED_QTY, CANCELLED_QUANTITY, ONHAND_QTY, HOLD_NAME

The same type of query works fine in 9i database. I hace a single sqlConfig.xml
Do I need to have 2 different sqlConfig files each for each database? How do I
specify the drivers?
Thanks

SV: Updated IDEA plug-in for iBATIS
Hi there! This plugin looks great, but are you also thinking about a feature like this: Generate CRUD SQL . with default class or alias as input param ? ??? This feature should also have the possibilities to change the default query names for each CRUD operation from e.g: Default: Custom: select$Class name$ ... to fetch$Class name$ ... delete$Class name$ ... to remove$Class name$ ... Then you could do this once, instead of 4 times in each xml for each bean. Keep up the good work! Best regards, Erlend Bjørge

Hi again! To quick respons last time: We now have intentions for automatically creating result maps and all CRUD operations (insert, select, update, and delete). Yes you are planning automatically creating all CRUD operations :-) That's realy good! ... but remember the option to override the default query names! Erlend

Automatic rollback with Spring for junit tests ?

Im trying to set
up some junit tests and want to take automatically a rollback for each test, in
a Spring context.
Any clues how to set this
property transactionManager (see below for the error) correctly in Spring ?
I have tried to use the AbstractTransactionalSpringContextTests
feature from Spring without any luck so far.
With the AbstractSpringContextTests
it works fine.

SV: Flushing of oscache in a cluster ?
Hi Brian! Are you sure you need to cache? Pretty sure :-) Have worked pretty well so fare. What metrics do you have to warrant the additional complexity? Until now we haven't seen it with extra complexity. When I started to use it, I liked it a lot :-) The shit hit the fan :-) when we tried to introduced load balancing, easily explained: 2 servers = 2 web and 2 admin = 4 applications :-) I think too many j2ee books convince developers to avoid frequent communications with the database without calculating the performance numbers in their own applications. The question is also, where to put the time to optimize your application, in the java code or the database. Of course the queries etc need to be good enough, but when you starts to talk about materialized views it's starts to get a little fishy. How much logic should you put in the application or database. Tricky question, I like to do it more in the application if I can. But when that's said we have similar solutions for the most heavy stuff. A Oracle guy made a package that made some kind of index table, he called it. Save us for many minutes in some quartz jobs we have running, also. I have removed N+1 selects etc. So we have focus on the query performance it's not that, of course we can be better too. -- Our application is something like yellow page catalogue +++, search text queries (we use Oracle Text), batch jobs counting up companies in business categories etc. http://www.aguiden.no (also a web cache over here...) Notice it's slightly quicker when searching the same word the second time = cached :-) The database server also server other applications and sometimes breath heavy. view and the database level with query rewrites. Each database vendor offers many features. That's why I like iBatis, it lets me work with my oracle database productively. Yes... I understand you, but as we want it with load balancing = 2 admin applications too, should also flush each other cache, I should realy want this oscache cluster mechanism to work. On paper it seems pretty easy, do a little stuff in the property file, setting up this GossipRouter, but where have a missed the point since it's not working ??? :-) Or should I do it a complete other way ? Find it strange that it seems no one seems to been trying this before ? h Anyway thanks for you thoughts still! Have nice weekend! Erlend

SV: Abator wishlist
Hi there Jeff! The primary key class is seperated so that the method signatures for selectByPrimaryKey and deleteByPrimaryKey can only require the primary key, and not the class that represents the entire row. I see, was thinking about that, but I havent got that problem, I always have like this fetchObjectById(Integer id), deleteObjectById(Integer key1, Integer key2). Shouldnt that be a better way ? If you need an update.. you have to have the data too, so what do you do then ? update(pk, bean) ? I did it that way because I have strong dislike ofusing half empty objects. Yes I see that problem (we have it J), but thats not related to select, delete methods where you only need the PK as an parameter, as we do it. For example,if the deleteByPrimaryKey method took the entire row as a parameter, everyone would have to remember what fields are in the primary key and only set those fields - yuck. Yes, Im agree, but why create and hole primaryKey object, instead of just sending in the PK itself as an parameter ? J But I guess this is related to the nature of how Abator works behind the scene ? Thanks for the answers anyway! Cheers, Erlend Bjørge
SV: Abator wishlist
Hi therae Christopher! PrimaryKey class in the first place the impact would have been greatly reduced and almost negligible. I learned my lesson and now always create a PrimaryKey class for every Domain object. And as you stated below, it provides a much cleaner interface to the selectByPrimaryKey and deleteByPrimaryKey methods. Yes, see that point.. .havent got that problem yet need to change the type of the pk J Need to think about that issue here. Thanks for info! Cheers, Erlend Bjørge

Connection hangs with SQL query string 1983 of length, can this be a SQLMap bug ?
Hi there!
When digging for the error in my previous message:
Possible to set timeout on the connection ?
I came over a very strange bug somewhere from SQLMap, the Oracle
driver classes12.jar and to the database Oracle 9.2.
I do a plain SQL without binding variables (I do $complexWhere$ -
myBean.geComplexWhere) in the
xml file) the query looks like this from the debug info:

com.ibatis.common.jdbc.logging.PreparedStatementLogProxy (Line: 50) -
{pstm-17} Types: []
(mine lineshifts in the query, and mine replacments of sql with .)
---
The query string is of 1983 length (if you count the spaces before the select
statment),
or 1973 without the spaces, no tail whitespaces counted. When I search e.g. for
'Galleri Henrik',
the query string get exactly total 1983 of length. But lets say it's 1983 then.
SO WHEN the query string is of exactly 1983 of length the SQLMap connection
hangs and I get some kind
of lock in the database (CURSOR BIND). Believe it or not !!! I still can't
believe it :-)
One Oracle guru told me that the case could be that Oracle are not able to
return the result
back again after doing this query and goes into somekind of wait modus. Waiting
for something
for the connection ?? I don't have a clue.
It's nothing wrong with the data or the SQL. I can copypaste this query string
into a SQL
tool, using the same Oracle JDBC driver as SQLMap does (I use DbVisualizer),
and run the
query with or without the whitespaces in front, and the query runs just fine
under 1 second.
This make me think, can this has something with SQLMap to do ? Do SQLMap
somekind of string
manipulating that could result in some kind of modus when the query string is
of 1983 in length ?
Oracle can handle more then that of course and should be discovered for a long
time agao if that
was the case ? Same with the driver, but what about SQLMap ??? A bug ?
It's a actually unbelievably this case, when the query string is less or larger
than 1983, no problem
at all, makes it even more strange. As my previous e-mail, when size is 1982 or
1984 no problem,
And it's not related to Galleri Henrik .. I can typ in '1234567 123456' - same
error, it's the length !!
--
Have you heard of this before ? :-) Any wild ideas ?? Something I should test ?
--
The quick solution is to remove many whitespaces in the sql string = become
less that 1983
of length with normal searches. Not that quick is to make binding variables.
Tested both, works just fine.
We use the SQLMap version available in january 2005.
Clues ?
Cheers,
Erlend
SV: Connection hangs with SQL query string 1983 of length, can this be a SQLMap bug ?
Hi there! Wow, that is a wacky one..it seems most likely that it is a driver issue (i can promise that there is no if(sql.length() == 1983) blowChunks(); code in SQL Maps. :-) Can you try it with the latest Oracle drivers? From all reports, the 10g drivers resolved a ton of bugs that were popping up. 10g drivers ? Not sure what you mean ? We are running 9.2, found det ojdbc14.jar driver and tested it and general speaking the driver worked with our code at least. BUT when I tried to reproduce the error from yesterday with old driver, I was not able to do it !! :-( What a luck. This error has been present for 1 week now. But it was yesterday I found out the 1983 case. Since yesterday, haven't done anything that should have caused any bug fix's with this problem, even brought back some CVS version of part of the code involved, no luck either to reproduce it now. The only difference I can think of is the load of the system at the moment from yesterday when I found the bug. Will try tomorrow again with the old driver to see if I can reproduce it, and then only switch to the new driver if it pop up again. It might not hurt to update to a more recent iBATIS build, too. Thougth of that too, but at the moment too much testing of rest of the application, to be on the safe side before an upgrade :-) But we should do it soone yes. -- Anyway thanks for the driver tip, think we has been using the classes12.jar by an old habit :-) Cheers, Erlend
How to force Integer instead BigDecimal with queryForMap for the value part ?
Title: Melding
Hi
there!
I have a queryForMap
like this:
HashMap codes
= (HashMap) sqlMap.queryForMap("retrieveAdminUserAccessCodes","testUser", "CODE", "VALUE"));
And the query like
this:
select
id="retrieveAdminUserAccessCodes" resultClass="java.util.HashMap"
parameterClass="String"
selectCODE,
VALUE from
ADMINUSERACCESS
where
ADMINUSERNAME = #value# /select
VALUE is
NUMBER(5) in a Oracle 9.2 database, when I get it back, codes,
the VALUE part
is of type BigDecimal,is it possible to get it as an
Integer instead ? hmm
Or is it other
ways to do this in a better way ?
Thanks!

One easy trick is to use the database function, in Oracle: initcap select initcap(name), initcap(contactperson) ... from company -- But still you have the problem with words that you don't want to initcap .. words like: and, or ... -- Let me know if you figure out a easy way handle those special word you don't want to initcap !! :-) Think you have to have some kind of list of words that should be in lower, maybe there are some kind of utility out there for that ? Take care, Erlend - -Opprinnelig melding-Fra: Folashade Adeyosoye [mailto:[EMAIL PROTECTED] Sendt: 10. juli 2005 14:27Til: ibatis-user-java@incubator.apache.orgEmne: Capitlizing first letter in words Is there any such feature in iBatis, where the first letters returned are capitalized, if all the data in DB are all lower cases? I know another alternative is to modify my setters to capitalize the first letter, I think its a pain in the rear to do that for all the attributes. Shardayyy
SV: SAXParseException, parsing the sqlMap-config.xml file!
Hi there! Apparently you have an element type that is not in proper order with the DTD. You are right, after downloaded the JEdit (thanks for the tip) with the xml parser plugin, tested with the sqlMap-config file from the sqlMap pdf file ... I found out it was the order. I had it like this: transactionManager typeAlias It should have been: typeAlias transactionManager Yes ! --- This problem started without my knowlegde for 1 month ago when I moved the typeAlias from the sql xml files to the sqlMap config file ... But didn't get any error messages then, so it seems to be cached somewhere in IntelliJ for me with out my knowlegde. But did a lot of refactoring of the alias... Strange that it's still cached somewhere. So that's why I though it was something else, but as usual you should trust the error messages :-) In away I did understand the error message, but couldn't beleive it :-) --- Check your sql map config and make sure your elements are properly ordered. Is there an reason why typeAlias should be first ? I found it more correct it should be after... But maybe because you can use typeAlias to more then just classes ?? Take care and thanks alot of clues to find the error! Cheers, Erlend
SAXParseException, parsing the sqlMap-config.xml file!
Title: Melding Hi there! In my IntelliJ, in our Resin web applications it all works just fine with SQLMap, but when I tries to run a scheduler job (Quartz) from command prompt using SQLMap from a .bat file (I run the job from IntelliJ it works fine)it seems thatsuddenly the parsingof theconfig file is not working anymore. I have also tried to copy the java command run by IntelliJ, into the bat file I'm starting so I get as close as I can get the same "environment" as the one in IntelliJ, still the same problem. Does anyone have any clues about what's wrong ? Some kind of conflict with the dtd ??? but why now ? Can it be some kind of conflict of .jar files ?Need to change the sequence ? Pretty lost here now. Thanks for any clues!
