Logging Native SQL queries

Hi all,
using JPA, i get all my data by ORM Instances, sometimes my pages are slow to load, i want to log JPA queries executed. I've search in JAS admin console without results.
how can i enable Log queries and/or where can i list them?
Regards,

Logging depends on which JPA provider you are using.
If you are using TopLink use the persistence.xml property "toplink.logging.level" = "fine".
For EclipseLink use, "eclipselink.logging.level" = "fine".
You could also enable the PerformanceProfiler.

Can't map Booleans from native SQL queries with Code First, EF 6, ODAC 12c R3 (Beta 2)

We're using Code First, EF 6, ODAC 12c R3 (Beta 2). When I use LINQ-to-Entities, I can map NUMBER(1) to Boolean fields as documented here: https://docs.oracle.com/cd/E56485_01/win.121/e55744/entityDataTypeMapping.htm#ODPNT8300
<oracle.manageddataaccess.client>
<version number="*">
<edmMappings>
    <edmMapping dataType="number">
      <add name="bool" precision="1"/>
      <add name="byte" precision="3" />
      <add name="int16" precision="4" />
      <add name="int32" precision="9" />
      <add name="int64" precision="18" />
    </edmMapping>
</edmMappings>
</version>
</oracle.manageddataaccess.client>
So far, so good:
    [Table("USER_PROFILE")]
    public class UserProfile
        [Key]
        [Column("LOGIN_ID", Order = 1)]
        public string LoginId { get; set; }
        [Column("IS_SUPER_USER")]
        public bool? IsSuperUser { get; set; }
var query = db.UserProfiles.Take(20);
However, when I try to map to the same class from native SQL, I get an exception:
// The real query is much more complex. This is just an example.
private const string AllProfilesSql = @"
            SELECT login_id AS LoginId, is_super_user AS IsSuperUser
            FROM user_profile
var query = db.Database.SqlQuery<UserProfile>(AllProfilesSql).Take(20);
>The 'IsSuperUser' property on 'UserProfile' could not be set to a 'System.Int16' value. You must set this property to a non-null value of type 'System.Boolean'.
Do you know any solutions or workarounds for this? Is it a bug?

Hmm, a feature request is possible; however, I'm not sure how feasible it would be to implement (if it is possible at all) in this scenario.
The challenge is that when using SqlQuery like this, EF calls into our override of the ExecuteDbDataReader method in OracleCommand (via System.Data.Common.DbCommand.ExecuteReader). That in and of itself is not an issue it's just that we don't know that this call is from EF and so we should use the EDM mappings from the configuration. In a "normal EF" scenario we know the call is from an EF "source" so can respond accordingly and perform the mapping.

Logging sql queries without any changes in existing apps

Hi!
Is it possible to log all SQL queries send from application to database via JDBC without any (or really small) changes in code of existing applications?
I'm new to JDBC so any suggestions/ideas/best practices are welcome ;)
Best regards.

Is it possible to log all SQL queries send from application to database via JDBCFirst is an assumption that the driver does in fact sends SQL. It might send some other form.
But excluding that and excluding that the driver explicitly sends it then you can create a proxy driver. You implement the driver to pass everything to the real driver. Along the way it collects the information.
You will find that that is quite bit of work. However it impacts the actual code very little and requires nothing more than loading the driver and changing the connection string in the code where it is used.

Fetch join with Native SQL Query?

Hello all,
I am using the J2EE 5.0 persistence api with the SUN appserver v9. As the java persistence api does not yet support spatial queries ("... where contains(polygon, point)") I have to use native SQL queries for that purpose.
Now my question is how can I "join fetch" my ManyToOne-related entities when using a native SQL query? Is this somehow possible using the SqlResultSetMapping annotation?

Never mind - the problem was to do with not specifying a class when creating the native query.

SQL queries in JDBC log?

Hi all.
I am using CMP entity beans on Weblogic 7.0 and would like to see the SQL queries
which the EJB container is executing. I would think that I should be able to see
these in the JDBC log file, but all I see there is DB connection logging.
I've seen discussion in docs and various newsgroups that implies that these queries
should be logged in the JDBC log. Do I have to change some parameter in order
to see the SQL queries in the log file?
Thanks.
AL

I'm using Sybase 12.5 with JConnect 4.5. Since I posted my question, I've found
a suggestion to define weblogic.ejb20.cmp.rdbms.codegen.verbose=true on the java
command line when I'm booting WLS. I can now see queries (as well as a bunch of
other stuff) in the stdout of the weblogic server. But I would still like to have
the queries logged. Of course, I could redirect stdout, etc. But I thought there
should be another way, esp considering that the is a JDBC log file. Any suggestions
would be appreciated.

logging
is left to the particular JDBC driver being used. Some drivers can be
very informative
or even over chatty, while others will log very little. What DBMS and
driver are you
using?

How to find SQL queries from listerner log

Hi,
I have a question related to Oracle listener log. I've tried searching on this forum but couldn't find any threads on this
Let me give a background on this. There are plenty of MSaccess databases which connect to Oracle database via ODBC link. I need to find out all the data items (Oracle tables / columns) that are referenced in the MS access applications. One way of doing that is open all MS access code components and look out for the ODBC links and extract the data items. This will be time consuming as there are several MS access databases (~450).
I am wondering is there is way to find the data items from Oracle logs. The only information available to me now is the listener logs. A sample record id given below. Is there any way to obtain the SQL queries that was used from the lister log.
08-MAR-2007 15:31:30 * (CONNECT_DATA=(SID=opr11a)(CID=(PROGRAM=MSACCESS.EXE)(HOST=PC12111)(USER=andrew.King))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.111.200.2)(PORT=1921)) * establish * opr11a * 0
Any help in this regard is much appreciated

BSP Application connection to SQL Express DB to execute SQL Queries

Hi There everyone,
I am not sure if I am posting this discussion in the correct section, but please try and help me out.
I have been tasked to write a BSP Application in the ABAP Workbench. The purpose of this application is to enable our Weighbridge operators to execute pre-defined SQL Queries by selecting certain criteria from the Application. The application is based on an HTML frontend which includes the Web Form (Input Fields, Submit buttons). We have 6 Weighbridges, each has its own HTML page in this application.
What I need to achieve is the following;
I need to know how I must setup the connection between the BSP Application and the SQL Express DB. Each Weighbridge has its own dedicated SQL Express instance + DB. These SQL Instances are not on the same host as where the BSP Application is located, I think the correct term is "External SQL Instances". Everything is on the same domain though.
What code would I need to add to the "OnInitialize" section in the BSP Application, to be able to establish the connection to the SQL Express database using Windows Authentication?
And what code would I need to attach to my submit buttons in the "OnInputProcessing" in the BSP Application, to execute a SQL Query to that DB and display the results in .CSV format back to the user?
I have attached 2 screenshots of what the BSP Application interface looks like. (This is what the user sees)
I am very new to creating BSP's, and I have never had to link to SQL from HTML / PHP before, so I basically have no knowledge of this.
Any help will be greatly appreciated.

Sorry for the late reply.
Yes, database is always available and online, not involved in Log Shipping or other things.
At the time of the connection failure I can find the following in the log of the application:

An SQL error occurred when executing Native SQL.
What happened?
Error 600 occurred in the current database connection "LCA".
What can you do?
Print out the error message (using the "Print" function)
and make a note of the actions and input that caused the
error.
To resolve the problem, contact your SAP system administrator.
You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
is especially useful if you want to keep a particular message.
How to correct the error
Database error text........: "Work rolled back: DbpError -28814 in
APS_ORDER_CH"
Database error code .......: 600
Triggering SQL statement...: " ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
? ? ? ? ? ? ? or'"
Internal call code.........: "[DBDS/NEW DSQL]"
Please check the entries in the system log (Transaction SM21).
You may able to find an interim solution to the problem
in the SAP note system. If you have access to the note system yourself,
use the following search criteria:
"DBIF_DSQL2_SQL_ERROR" CX_SY_NATIVE_SQL_ERRORC
"/SAPAPO/SAPLOM_PLANNING" or "/SAPAPO/LOM_PLANNINGU08"
"/SAPAPO/OM_ORDER_CHANGE"
If you cannot solve the problem yourself and you wish to send
an error message to SAP, include the following documents:
1. A printout of the problem description (short dump)
To obtain this, select in the current display "System->List->
Save->Local File (unconverted)".
2. A suitable printout of the system log
To obtain this, call the system log through transaction SM21.
Limit the time interval to 10 minutes before and 5 minutes
after the short dump. In the display, then select the function
"System->List->Save->Local File (unconverted)".
3. If the programs are your own programs or modified SAP programs,
supply the source code.
To do this, select the Editor function "Further Utilities->
Upload/Download->Download".
4. Details regarding the conditions under which the error occurred
or which actions and input led to the error.
The exception must either be prevented, caught within the procedure
"/SAPAPO/OM_ORDER_CHANGE"

Hi,
the error DbpError -28814 denotes that an object cannot be found.
Can you maybe tell me your exact liveCache version (incl. Build level) and LCA Build?
Additionally, please copy the relevant error information from the file (/sapdb/data/wrk/<SID>/)knldiag.err into this thread.
Which exact 'liveCache test program' are your referring to (which of the /SAPAPO/... transactions)?
Kind regards,
Roland

Developing portlets for dummies (sql queries)

Hello, I've been trying to build a dynamic menu. First I went with just plain old plsql: i created a function in the portal schema that returns an unordered, nested list of the pages in my pagegroup and called that function in a regular pl/sql item on my portal page. I did this by querying the wwpob_page$ table and that went just great in my test&development setup (of which I am the admin of course :))
Then I realized that since I'm not an administrator of the server hosting our portal and I only have very limited privileges (I am only a page group administrator) I will probably not be allowed to utilize this function nor will they agree to install it in the portal schema, and I decided I should build a portlet that does the same thing (so it can be registered and so on, and so it can use the synonyms and tools that are available to registered providers). There already is such a portlet (and provider) registered for use in the target portal, but I don't like it because i uses tables and hard-coded styles so I will cook my own, better version. :)
So I downloaded an example portlet and am getting the hang of it, but now I just can't for the life of me figure out how to enable any sql-queries. I have run the provsyns-.sql script, logged in as test_provider/portal and installed my portlet-package as test_provider user. I can see the available pl/sql packages in Toad, but there are no tables or views for me to to see. That means I can't query the portal tables that I need to.
edit: ok, stupid user error; I suck at using Toad, so I was looking at the wrong schema altogether :D So now i see the public views and packages, so forget that bit of the question.
But still, I cannot see even wwsbr_all_folders -view, much less the wwpob_page$ -table. I cannot see any way to find the pages that are in my page group. Somehow it must be doable, right?
Have I done something wrong, missed a step in enabling my test-provider / schema perhaps? I don't really know what I'm doing, but I followed instructions here: http://home.c2i.net/toreingolf/oracle/portal/my_first_plsql_portlet.htm (excellent instructions, thanks!)
So should my portlet be able to access those tables or not? How the heck has the third partly portlet maker done it?
i'm on OracleAS Portal 10g Release 2 (10.1.4)

i see your perspective now. and let me give a perspective to my first reply too.
what i proposed to you was the answer of what i quoted in the message. that is, why didn't you see those views in the new schema you created! and it is still ok but it is done in the portal schema for which you should have privielges too and i assumed you had. my mistake!
now, i can relate your privacy concerns with your earlier message:

- by downloading an example portlet, you probably mean you created a new schema. because provsyns work on a schema.
- if you are not the administrator of the portal, and may not be able to access some portions of the portal, it means that you do not use the portal user (the user which serves as the owner of the portal schema).
- now, your plan to create a new schema and give those privielges would still not work. because, by creating a new schema you cannot sneak in to the oriignal portal schema if you do not have privileges to do it. obvious, right? otherwise, it would be a vulnerability of the software that you can see what you are not allowed to see by creating a new schema.
- however, there is a bright side here. the views give records based on your privileges.
- so if your administrators have generated them already or if they generate on the original portal schema, then you may see the pages and items that you have privileges to see and no more.
so now, you may ask the administrators if they have already done it, and if not, then if they would be willing to do it.
hope that helps!

? in SQL Queries and not using prepared statements

Using EclipseLink 1.1.1
Prepared Statements are disabled
In our production server something went wrong and one of our Read Queries started erroring. A DatabaseException was thrown and we log the "getQuery.getSQLString()" statement. We found this query in the logs:
SELECT t1.ID, t1.NAME, t1.DESCRIPTION, t1.EXTREFID, t1.STYLESHEET, t1.DDSVNVERSION, t1.FIRSTNAME, t1.LASTNAME, t1.EMAILADDR, t1.PHONENUMBER, t1.ADDRESS, t1.ADDRESS2, t1.CITY, t1.STATE, t1.POSTALCODE, t1.COUNTRY, t1.ADMINACCTNAME, t1.HASDOCUMENTS, t1.HASTIMEDNOTIFICATIONS, t1.STATUS, t1.ENTRYDATE, t1.EVALEXPDATE, t1.LASTREMINDDATE, t1.FULLUSERS, t1.LIMUSERS, t1.REQUSERS, t1.ISENTERPRISE, t1.EXPDATE, t1.ISDISABLED, t1.DISABLEDDATE, t1.NEEDLICENSEAGREEMENT, t1.ISWARNINGDISABLED, t1.LOCALE, t1.TIMEZONE, t1.CURRENCY, t1.DOMAIN, t1.DOCUMENTSIZE, t1.EXTRADOCUMENTSTORAGE, t1.ONDEMANDOPTIONS, t1.SSOTYPE, t1.RESELLERID, t1.ACCOUNTREPID, t1.LASTUSAGEREPORTDATE, t1.NEXTUSAGEREPORTDATE, t1.USAGEREPORTATTEMPTS FROM T_SSOOPTIONS t0, T_CUSTOMERS t1 WHERE *((((t0.SSOENABLED = ?) AND (t1.SSOTYPE IN (?, ?))) AND (UPPER(t1.DOMAIN) = ?)) AND (t0.CUSTOMERID = t1.ID))*
Notice the values weren't entered into the where clause. We had to bounce the application to fix the problem. I've never seen this before. I've added more debugging statements to the code - so if this happens again in the future I'll have more information to report on. In the mean time I'm wondering if anyone else has every seen a problem of this nature.

Database error due to invalid SQL statement.
I don't have a stack, we were catching the exception and not printing the stack :(
Like I mentioned in my first post, I added more debugging code (e.printStackTrace()). I understand this is hard to track down without more information. I was just hoping you guys had seen something like this before and had any insight. Like I mentioned before: this is on our production server. I've never seen this type of error before. That particular server (we run in a cluster mode) had been up for several days and then started generating that error. IT bounced the node and everything went back to normal. We have been using toplink for about 5 years now and have never seen this problem, until August 3rd 2009. The only thing that has changed recently is our migration from toplink 10 to EclipseLink. I was wondering if anyone knows if anything had changed in EclipseLink/toplink 11 with the generation of SQL queries.
I'll keep looking. There is more debugging code in there now. Since the error was "Database error due to invalid SQL statement" this implies the SQL was generated, exited that part of the code and was sent to the db where it failed. I'm afraid the printStackTrace won't help if this error happens again.

Named parameters in Native SQL

A little background first:
Our website uses Hibernate as it's JPA provider, but we've run into several issues with it, one of which they actively refuse to fix out of pure arrogance, even when we gave them a good patch for it. The other one is a performance issue that can be greatly improved by passing arrays as parameters, which I've read rumours is supported in EclipseLink. I first tried implementing a Hibernate UserType as they've specified and it turns out they never read them into the Map that looks-up parameter types during binding, even though it's loaded from their hibernate.cfg.xml. In other words, they're only pretending to support custom user types, but unless you're writing-out the full manual loading of their configuration, there's no way to do it.
After a day of trying to fix all the relation annotations that EclipseLink finds unacceptable in our project (which only uses native SQL and EntityManager.find for selects) I finally got it running and came to discover you don't support named parameters in native SQL. That was really disappointing, because a few months ago we migrated all our queries to named parameters, because positioning ones were too difficult to track and caused more bugs when we had to add more criterias.
My questions are these:
Are named parameters for native SQL not supported by JPA specifications or because they are considered low priority?
Would you accept a patch that supports them?
Can we really use arrays and/or lists as parameters in queries like this "SELECT * FROM some_table WHERE my_column_a IN ? AND my_column_b NOT IN ?"
If yes to above, would it still work if the first one is an array of integers and the second is an array of strings?
Would it work if it's in native SQL and the column types cannot be resolved due to query complexity?

Performance of native sql query detoriates

Dear Experts,
The performance of my native SQL query is bad. On the database the query takes less than 5 seconds to process. From my abap program I get a session timeout dump after 10 minutes. What might be the possible reason.
Warm Regards,
Abdullah

I am not a DBA, but this is a wild guess.
I have a native SQL query. It was running fine all morning(transported it to production today). By afternoon the report was not giving any output.
I went to the MS SQL query analyzer and executed the query, it returned the results in less than 5 seconds. The same query when I was executing from SAP using native SQL took more than 10 minutes and gave a dump(time exceeded).
My database guy asked me to execute the following on the database. Dbcc dbreindex('tablename')
The report is running fine since then. I am still not satisfied if this is the reason the performance is back on track, but yeah the report is running fine again. There seems to be some problem with the indexes.
I am using standard classes provided by SAP to execute my query and after execution the resultset reference object is being closed, I am closing the connection.
the code is as below.

How to see what SQL queries are made to my Database Server?

Hi all,
I'm a newbie. I'd like to know if there's a way to find out what SQL queries are being made to my Database server at the server end.
Is it possible that Oracle Database Manager logs this information (including the exact query/SQL)somewhere in its logs? How to enable such an option and/or view the recent SQL queries made ?
Please enlighten me. Thanks in advance.
Thanks and Regards

"I checked the V$SQLTEXT view too. It has only 64 characters for SQL_TEXT field." Yes yes but you might have noticed that it also has the column called piece. The view shows the full SQL statement broken up into little pieces. Use ADDRESS and HASH_VALUE to link to v$sql. There is also a view V$SQLTEXT_WITH_NEWLINES that throws in some line separators to make it "easier" to read.
Example below shows full text of SQL statements currently executing.

SQL> column hash_value noprint
SQL> break on hash_value skip 1

Performing sql queries in java without using java libraries

i wonder whether its possible to perform sql queries beginning from create table to updating queries without using the java sql library.
has anyone written such code.

You could use JNI to talk to a native driver like the Oracle OCI driver. Doing this is either exiting or asking for trouble depending on your attitude to lots of low level bugs.

Sql queries - slow database

hi all,
is there a general but specific way to generate a list of sql queries that are consuming most resources and resulting in slow database performance?
thanks.

There are very few ways in this world that are "general but specific".
You can use "general" tools like StatsPack and AWR.
You can write "general" queries on V$SQL, V$SQLAREA, V$SQLSTATS.
You can use "specific" methods like Tracing.
You can use "specific" methods like Client side (or Application Server side) Logs.
