SQL remote query and data-dictionary

Hi,
We are considering the implementation of SAP Business One 2005. I've installed a demo version but in order for it to continue to support some business functions I need to perform a number of SQL queries against the data. Unfortunately I'm having difficulties in getting the answer from our reseller.
Does anyone know the answers to the following question. I'd very much appreciate some help.
1) Is there a data-dictionary document showing which tables perform which roles and the associated joins/associations.
2) Is it 'advised' to open the SAP datasource directly to perform a SELECT query to obtain the results or should a third-party tool be used?
3) Do I need the SDK if I want to perform direct SELECT queries or if I want to automate posting invoices to SAP? We have competent programmers in the company - I believe they use VB6 and VB.net.
4) Is there an example if I simply wanted to query all suppliers within SAP? (e.g. SELECT NAME FROM Supplier_tbl...etc..etc)
Any help would be very much appreciated - it's a huge application and I'm struggling a little.
Many thanks,
Gavin Russell.

Gavin,
The forum that you have posted your questions in is or questions related to the SAP Business One Integration for SAP NetWeaver. Your questions seem to be along the line of general data access to SAP Business One. You should typically post those types of questions in the SAP Business One Discussion Forum or the SAP Business One SDK Discussion Forum.
As to your questions ...
1. The definition of the SAP Business One table schema is part of the SAP Business One SDK Help Center documentation. You simply need to install the SAP Business One SDK Help and you will have it. There is not a "data dictionary" other than this documentation.
2. Typically any direct access to SAP Business One data using SQL is discouraged as if data corruption occurs as a result of it, the environment would not then be supported by SAP.
3. If you want to push data into SAP Business One, as stated, direct access to the Business One database is forbidden. You would use the SAP Business One SDK for this.
4. You can use the SAP Business One Query Manager/Wizard in the SAP Business One product which in essence is performing SQL type SELECTS for data on Business One tables.

Eddy

Result_cache and data dictionary views

Hi,
Are there any special considerations when caching the results of a function which uses data dictionary views to determine it's results?
This question has popped because I have a such a result_cached function for which the result_cache objects are not getting invalidated even when the underlying data dictionary views have changed and the function gives 'stale' values in it's output. Adding the relies_on clause has not helped either.
Here is what I am trying to do:
The function accepts table name as its input and tries to determine all the child tables using the sys.dba_constraints view. The results are returned in a pl/sql table and are cached so that the subsequent calls to this function use the result_cache.
Everything works fine for the parent/child tables which have been created before the creation of this function. All the results are correct.
The problem starts when a new child table is added to an existing parent table.
The v$result_cache_objects view shows the result of this function as 'Published' and the output of the function does not show the newly created child table.
Same is the case when an existing child table is deleted; the function continues to return it in the output as it is pulled from the result_cache.
Oracle version:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

>
Restrictions on Result-Cached Functions*
To be result-cached, a function must meet all of these criteria:
* It is not defined in a module that has invoker's rights or in an anonymous block.
* It is not a pipelined table function.
* It does not reference dictionary tables, temporary tables, sequences, or nondeterministic SQL functions.
For more information, see Oracle Database Performance Tuning Guide.
* It has no OUT or IN OUT parameters.
* No IN parameter has one of these types:
o BLOB
o CLOB
o NCLOB
o REF CURSOR
o Collection
o Object
o Record
* The return type is none of these:
o BLOB
o CLOB
o NCLOB
o REF CURSOR
o Object
o Record or PL/SQL collection that contains an unsupported return type
It is recommended that a result-cached function also meet these criteria:
* It has no side effects.
For information about side effects, see "Subprogram Side Effects".
* It does not depend on session-specific settings.
For more information, see "Making Result-Cached Functions Handle Session-Specific Settings".
* It does not depend on session-specific application contexts.

Discrepancy in OUTPUTLEN in ALV_FIELDCATALOG_MERGE and Data Dictionary

Hi Gurus,
I have a program that uses ALV_FIELDCATALOG_MERGE to create a dynamic table. When running it using table VICDCONDCALC or VICDCONDDIST the output length produced for field CALCNUMBER (data element RECDCALCNUMBER) is 6 however when trying to view it in the data dictionary table like DD04L the output length is 5. When I debugged the program there is a statement IMPORT NAMETAB X030L_WA X031L_TAB ID TABNAME. in FM DD_GET_NAMETAB after it passes through this statement the internal table X031L_TAB has the field above with 6 as the External length. Where does the FM retrieved the value 6? Is there any database/transparent table in SAP that I could use to query the table that will produce value of 6?

There is always a problem with output length in the FM - REUSE_ALV_FIELDCATALOG_MERGE. Go to utilities> settings>ABAP Editor --> Editor --> select the check box Downwards-comp line (72). Try to run the program I think the output length will be same for both.
Hope it will work.

Preetham

Importing SQL Server Schema and Data

What is the best way to go about importing schema objects (tables, contstraints, triggers, stored procs, etc.) and data from SQL Server to Oracle?

No offence taken :)
But I have copied data from SQL Server DB to Oracle using SQL Server Enterprise manager Data transformation services.
About 30 tables with summary amount a few hundred thousand rows (~300K) took about 1.5 hour.
Did it several times when tested and run for production in a data conversion project. Of course when copied to Oracle all data was processed to adapt for our new data model, but that is another story.
It was quick and easy solution. OK if one needs to copy at least a few M rows then probably he needs to look for different tools.

Weird problem with mysql query and data table buttons !!!!

Hi,
I'm using jsc 2 update 1 on windows and mysql 4.1 . I have a page with a data table. One column of the data table contains "Details" buttons.
Source query for the table is :

The tbl_tesserati.data_nascita is a mysql date field.
The click event handler code for the "Details" Button is:
public String btnModificaTesserato_action() {
        try{
            TableRowDataProvider rowData= (TableRowDataProvider)getBean("currentRowTesserati");
            getRequestBean1().setId_tesserato((Long)rowData.getValue("idTesserato"));
        } catch(Exception ex) {
            log("errore nella query",ex);
        return "dettaglioTesseratoSocieta";
    }When i run the project and open the page the table is correctly rendered and populated with some rows. But when i click on details button nothing happens, the page is simply reloaded.
If i set a breakpoint in the code line TableRowDataProvider rowData= (TableRowDataProvider)getBean("currentRowTesserati");the debbuger does not stop the code execution ! As if the button was never clicked!
I tried to modify the source query to :
SELECT tbl_tesserati.idtbl_tesserati idTesserato,

Using this query everything works well !! The click handler works and the debugger too !!
I changed only the AND in OR !!!
I also tried to change mysql-x-x-connector driver but without solving my problem.
Can someone help me ?
Thanks

You'll find that it is more to do with the way MySql deals with dates than anything else! Depending on how your date field is setup, then try using a BETWEEN statement for those 2 lines in your first query e.g.
AND ( tbl_tesserati.data_nascita BETWEEN ? AND ?)
The date column needs to be in the ISO format to work. If you examine your second query output, you might discover that the output is only going to refer to one parameter (probably the OR one). Did you manage to view the output logs from the application server? You would have got an idea from there with a message like stating a conversion error'.
Alternatively, you could try using the to_days() function and convert it directly to a number which would be a lot easier to deal with. For example:
AND to_days(tbl_tesserati.data_nascita >= ? )
AND to_days( tbl_tesserati.data_nascita<= ? )
Or try the BETWEEN version with to_days() and see what you get.
More info about date formatting (v5) here:
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_to-days
Before I forget, sometimes you may need to treat dates as Strings rather 'Long' as you did.
As a matter of interest, did you try your query in a different piece of software?
If my queries are a little more complicated, I tend to try MySql queries out in the free MySql query browser and also double check in another to verify certain issues. I found it easier to develop SQL in a seperate program then import the final version to JSC making the required modifications for parameters.

Query on data dictionary results in large number of physical reads

I don't understand why I am getting 80,000 physicals for this query. I am not looking for help re-writing this. I just don't understand why I would hit the disk at all.
My understanding had been that v$views where sql structures that pointed to x$tables. These x$tables are sql structures.
underneath, the x$tables were linked lists stored in memory. This is why when you bounce the database, all the data, gets reset. Since it is not saved to disk.
I am doing a simple insert/select off of v$open_cursor that is resulting in 80,000+ physical reads. I am posting the tkprof. It is all from v$open_cursor.
mysid_table has 6 records. It is 1 mb in size
if I index mysid_table.sid the query reduces to 20,000 physical reads. (but all the physical reads are on v$session_event)
the sequence number I am passing returns 2 SIDs
insert into my_save_table
select *
from v$session_event
where sid in (select sid
from my_sid_table
where id = vseq);

SAPbouiCOM.DBDataSource.Query and Date fields

When I try to add a Condition that uses an Alias for a database field of type datetime, the Query method crashes.
Is there a specific Date format that I am supposed to use?
I am currently using the SAP date format and I also tried the database date format. Both crashed the Query method.

My customer's date format is mm/dd/yy and that is the format I was using. Here is what my code looks like for debugging this problem which is still crashing on the Query method:
conditions = new SAPbouiCOM.Conditions();
condition = conditions.Add();
condition.Alias = "U_PLS_PkgD";
condition.Operation = SAPbouiCOM.BoConditionOperation.co_GRATER_EQUAL;
condition.CondVal = "03/11/2004";
dbDataSource.Query(conditions);
I have also tried the following date formats:
condition.CondVal = "11/03/2004";
condition.CondVal = "03-11-2004";
condition.CondVal = "2004-11-01";
"U_PLS_PkgD" is a field in my user table that is of type datetime in the database. I can Query with varchar and int database fields. Just not datetime fields.
Please advise. Thank-you.

SQL 2000 Log and data file free space

HI ~ In SQL 2000, are there any tsql I can get the free space of the mdf and ldf file ?

I would like to look into EACH ldf too like SQL 2005 onward using sysfiles

DBCC sqlperf(logspace) will just sum all the ldf size.....
Hello,
Below would work in SQL2000.I did not tested it on 2000 ,I dont have 2000 anymore.This will give information for data and log file free space for all databases

Labview remote control and data transcation

Hi,
We have a complicated timing control system written in labview
6.1 running on our lab PC-1. Since it is not easy to upgrade to a most
recent version and limited PCI-slots, and we need to add a few device
control programs (written in C++ or updated labview), we are thinking of
an ultimate control system with two PCs and let the old timing program
be a "slave" of "master" computer PC-2. OS for both PCs are windows XP.
The communication between the two PCs are
fairly straight forward: suppose on PC-1, the program breaks into two
parts: part A and part B. PC-2 sends selection messages to PC-1 to
determine which part needs to be running during a particular shot. It is
true that to our best interest we might need PC-2 to send data to
PC-1, in case for a particular run we have to change some data values of
timing program.
The problem might appears to be a piece
of cake to you experts. It is worth mentioning that on PC-1, any
changes made to the timing program is nontrivial due to its structual
complexity. The program is DAQ based (finite) pattern generation (using a
lot of PCI 6534/PCI 6713/counters, external clocking).
The
reqiurement for speed is not high. PC-2 can in general wait for 1
second before PC-1 receives a message and start to output. On the
other hand, the smaller the delay, the better.
We have
considered a few communication options like TCP/IP, RS232 ports, etc.
But before we start implementing the changes, we would really appreciate
your suggestions/comments!
Thanks very much in advance
for your time!
Kunyan

Kunyan,
there are really several different ways to solve this. The major question is: Is this a handshake protocol or simple "notifications"?
If it's simple notifications, things are getting quite easy.
You can use TCP/UDP/DataSocket/STM if there is a network connection between both PCs. Otherwise, RS232 might be a good idea as well for sure.... but i suggest a network technology in order to reduce delays.
STM is a protocol built up on TCP and even if you do not use it (it is not available for LV 6.1!), it might get you some ideas about defining a custom protocol.
hope this helps,

Using cursor to query from data dictionary

Hi
I am having a weird problem.
In a procedure, I like to compress some tables
so I wrote a cursor like this:
CURSOR crs IS SELECT OWNER,TABLE_NAME FROM ALL_TABLES WHERE TABLE_NAME LIKE '%ABC';then I'm opening the cursor in for loop and running
xSql := 'ALTER TABLE ' || X.OWNER || '.' || X.TABLE_NAME || ' MOVE COMPRESS';
EXECUTE IMMEDIATE (xSql);Now strangely enough, my cursor is not fetching any record at all inside procedure!
But when I run the cursor select statement of its own in SqlPlus, it does fetch lots of record!
So, what's wrong??
Edited by: movilogo on Jun 30, 2010 9:25 AM

Working of LMT datafile and ASSM bitmaps + data-dictionary

Hi,
I was looking to have some clarification on effective changes that take place within the database during a datafile addition/resize in a LMT. Hence what are the scenarios where a datafile resize would be better than a datafile addition and vice-versa?
I have not been able to find clear guidelines to the above.

From the perspective of bitmap in datafile header is it not true that multiple datafiles with separate bitmaps in their headers can reduce the contention for multiple hot blocks in a single datafile?
To phrase my question differently, when does the additional calculations for LMT,ASSM and data-dictionary maintainance rule in favor of resizing a single datafile(ending in a sort of big file tablespace) rather than adding datafiles?
